    Recycling is very important and necessary in today's world. The most important reason for this is that human progress and industry have made it possible for people to have lots of things, and when people have many material possessions, they are bound to throw some of them away.

    Recycling is a way for us to keep the world clean as items are broken down and used again, preventing the littering of the environment. Instead of throwing all your garbage into the dustbin, you should separate paper, metal, glass, and plastic into different containers. They can be turned into valuable compost, which is the perfect plant food and soil disease fighter.

    You can see if an item has been made from recycled materials by its label. If it's been recycled, it will say so. Also instead of always buying new clothes, you can arrange to have a clothing exchange with your friends. You bring clothes you don't want and pick items you want from what other people have brought. Not only does this save the environment, but it also saves your money. This saying can be applied to all sorts of things: books, CDs, furniture, etc. Also try shopping at second-hand stores, because they often have lots of items still in good shape for you to choose.

    Many countries have made it easy for people to recycle, as alongside the normal garbage trucks, special garbage trucks come and pick up recyclables. However, in some countries the responsibility is left up to the ordinary people to recycle. Recycling represents just one way in which we can help the environment. But it is an effective one and one that we can actively influence.

A. Fallen leaves can also be recycled. B. Having too many things causes a lot of garbage. C. You should try to buy products that have been recycled. D. Products made with recycled materials are as good as new products. E. This creates a lot of garbage which in turn destroys the environment. F. Remember, what is one person's unwanted object can be someone else's treasure! G. Therefore, it needs attention in society so we can continue to make our environment livable.

    Have you felt annoyed when a cell phone rings during the class? Something must be done to stop this. Now in New York City, USA, a rule is carried out in schools. Students can't even bring cell phones to school. Is it a good thing or not?

    Anxious parents say that cell phones are an important tool in holding New York City's families together.

    "I worry about it." said Elizabeth Lorris Ritter, a mother of a middle school kid. "It's necessary in our everyday life. We have a washing machine. We have running water, and we have cell phones."

    Many American parents think cell phones connect them to their children on buses, getting out from subways, walking through unknown places.

    "I have her call me when she gets out of school," said Lindsay Walt, a schoolgirl's mother. "No one in New York is going to let their child go to school without a cell phone."

    What about the cell phone owners, the students? Most of the students said cell phones were essential and the cell phone was like an extra hand or foot for them.

    "I feel so empty," said May Chom, 14. There is also no way to listen to music on the way to school without my phone. It will be a really, really boring trip."

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset （思维模式） helps them embrace learning a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    “Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.
    With her eyes shining, Tori brags, “You bet I did, Sean told me two days ago.”
    Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.
    An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic-breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.
    If we know that gossip can be harmful, then why do so many of us do it? Theanswer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor(传言) can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of belonging or even superiority(优越感).
    Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The dos and don'ts conveyed through gossip will never show up in any student handbook.
    The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, thing about why you want to gossip and what effects your “juicy story” might have.

The healthy adolescent boy or girl likes to do the real things in life,to do the things that matter. He would rather be a plumber's mate and do a real job that requires doing than learn about hydrostatics(流体静力学)sitting at a desk, without understanding what practical use they are going to be. A girl would rather look after the baby than learn about child care. Logically we should learn about things before doing them and that is probably why the experts enforce this in our educational system.But it is not the natural way—nor, in my view, the best way. The adolescent wants to do things first for only then does the appreciate the problems involved and want to learn more about them.

    They do these things better in primitive life,for there at puberty(青春期) the boy joins his father in making canoes,patching huts,going out fishing or hunting.He is serving his apprenticeship in the actual accomplishments of life.It is not surprising that anthropologists(人类学家) find that the adolescents of primitive communities do not suffer from the same neurotic(神经质的) “difficulties” as those of civilized life.This is not,as some assume,because they are permitted more sexual freedom,but because they are given more natural outlets for their native interests and powers and are allowed to grow up freely into a full life of responsibility in the community.

    In the 19th century this was recognized in the apprenticeship system,which allowed the boy to go out with the master carpenter,or ploughman,to engage in the actual work of carpentry or roof-mending,and so to learn his trade.In some agricultural colleges at the present time young men have to do a year's work on a farm before their theoretical training at college.The great advantage of this system is that it lets the apprentice see the practical problems before he sets to work learning how to solve them,and he can therefore take a more intelligent interest in his theoretical work.

    Since more knowledge of more things is now required in order to cope with the adult world, the period of growing-up to independence takes much longer than it did in more primitive community,and the responsibility for such education,which formerly was in the hands of the parents,is now necessarily undertaken by experts at school. But that should not make us lose sight of the basic principle, namely the need and the desire of the adolescent to engage responsibly in the real pursuits of life and then to learn how—to learn through responsibility, not to learn before responsibility.

    Changing technology stimulates (刺激) the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent?

    After the Industrial Revolution, machines began to replace manual workers. The process played out in agriculture as well as manufacturing so that groups of agricultural workers were replaced and forced to move to cities to make a living.

    When machines took away much of the manual work, people became less physically active and gained weight. The sedentary (久坐的) lifestyle contributed to a worldwide spreading of overweight and related metabolic disorders such as heart disease, secondary diabetes and kidney disease .

    As our bodies rested, our brains were forced to work harder, however. It is much more difficult to drive through an overcrowded modern city than it is to move around in a small rural village, for instance. Modern jobs are also more complex and urgent and they require more education because employees need to process new information quickly. Even during our leisure time, our brains work harder due to greater availability of books and explosion of audiovisual media, for entertainment, study, music, news, and so forth.

    Now in the Internet age, the amount of information grows fast along with the advance of electronic technologies. The number of people with whom we interact electronically grows by leaps and bounds thanks to the ease of use of social media like Facebook and Twitter.

    All of this extra work for our brains makes us more intelligent. That helps explain why human intelligence increases steadily from generation to generation in all developed countries, a phenomenon named the Flynn Effect. Of course, there are other reasons, including improved nutrition, better medical practices that reduce brain damage, and improved sanitation and public health that reduce diseases of childhood.

    In the P.G Wodehouse novels, Bertie Wooster got away with being a fool because Jeeves was there to back him up with superior brain power. Similarly, people of the future are at risk of being less intelligent because machines will do their thinking for them.

    Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. Moreover, the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capability of mere human air traffic controllers.

    Artificial intelligence exists in many fields of modern life for the simple reason that intelligent machines can already outperform humans, including some aptitudes (天资) which were once thought to be a human advantage, such as playing chess or recalling details in a game of Jeopardy.

    Machine intelligence is increasing much faster than human intelligence. As machines get smarter, they will do more of our thinking for us and make life easier.

    Instead of struggling to identify ourselves to some electronic system via passwords that are secure only if they are hard to remember, the system will work harder to identify us using biometrics (生物测定学) such as fingerprints or even the individual sound of our hearts. More technologies of the future may also be voice-activated so that we will talk with machines much as we would talk to a friend.

    In the future, the electronic assistant will develop to the point where it serves similar functions as a real living chief male servant of a house, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests .”

    At that point, our long struggle with challenging technologies is at an end. Like Bertie Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain—the electronic assistant. Starved of mental effort, our brains will return to an earlier or less advanced form.

    The future is still in the fog.

    Everyone takes drugs. Sometimes a drug might be called a herb but the effect is the same. Drugs and herbs can make life better for they are used to improve health. From the simplest headache to a cure for cancer, people believe that certain drugs can help them. But there is danger if the drugs are not used in a proper way.

    American teenagers sometimes use certain drugs to feel good. They call this “getting high”. The problem is that once a young man or a young woman has the feeling of “getting high”, they want to do it often. If school is boring or too hard, students might get depressed and a drug or herb might help them feel better. If the student takes too much of a drug, the body may change in a wrong way such as a confused mind, poor sight, a headache, and an uncomfortable stomach.

    Schools now have D．A．R．E．program which means Drug Abuse Resistance Education. This program was started so that young students from age 10 to 18 might understand how a drug affects their bodies. The main point of the program is education. Once a student understands certain drugs can cause ill health，he will know he should not use them.

    Education is the key to good nutrition as well. If a student eats correctly, he or she will be full of energy which leads to good study habits and good grades. Poor nutrition may cause the need for more sleep and poor concentration. Proper food is similar to the proper use of drugs. Both allow a healthy body to grow while misuse of them prevents a person from developing normally.

    When something goes wrong, it can be very satisfying to say, “Well, it's so-and-so's fault.” or “I know I'm late, but it's not my fault; the car broke down.” It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner's key to success.

    Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don't rely on the person. You should accept that the person. Ask to work with a different person, or don't rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

    This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don't have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stop on for success.

    Happy, angry, amazed—these are some of the emotions we like to express these days when we're sending a message on our smartphones! That's why many of us now add little pictures to our texts to brighten up someone's mobile screen but we're also using them as a quick way of telling someone how we're feeling. Yes, emojis (表情符号) have become a popular tool for communication.

    The emoji was first invented in Japan in the late 1990s and the word “emoji” comes from the Japanese words for “picture” and “character”. The number of different images has greatly increased since then and now we have a picture for nearly every mood or situation.

    Why are emojis widely used today? Professor Vyv Evans says, “Increasingly, what we're finding is that digital communication is replacing face-to-face talk in some ways. One of the reasons why emojis are so interesting is that they really do enable us to express our emotional selves much more effectively.”

    Another advantage of emojis is that they are an international language—they don't use words but tell a message with pictures so they can be easily understood whatever your native language is.

    But as linguist (语言学家) Neil Cohn says, “To many, emojis are an exciting evolution (进化) of the way we communicate; but to others, they are linguistic Armageddon.” It does show by using emojis, there is a lot more to our communication than words alone, but does this also mean that the traditional writing will die out one day?

    Twenty-five years ago, as a parent educator, I began reading about the dangers of praise. I was completely shocked by what I was learning: praise is not good for our kids. How could that be? So I spent years talking with experts, reading about the effects of praise, and finally decided to close the door on praise and focus on building an encouraging family.

    Even today, with many studies available to parents, I still hear people say, "How can that be? How can saying 'Good job' or 'You're smart' be bad?" I understand. It can be a difficult habit to break.

    If we tell a boy "You are so smart!" when he brings home an A in his math test, how does he feel when he comes home with a D? If we've told him that he is smart, then he will more likely feel a failure when he struggles with homework — "I'm supposed to be smart. Why can't I do this?"

    Praise trains children to depend on constant feedback on what a "great job" they are doing. This dependency shatters rather than builds children's confidence. Praise trains children to ask, "Do you like it?" "Did I do a good job?" "Are you proud of me?" They begin to believe that what others think is more important than what they think about their achievements and mistakes.

    Praise breaks the relationship between parents and children. Without even realizing it, parents may be using praise as a tool to direct the child's behavior. The message is clear — I approve of you when you … and I do not approve of you when you … Living with this kind of constant judgment can damage not only the child's confidence but also the relationship.

    The solution to the problem of praise is encouragement. Encouragement can be given at any time, to anyone, in any situation. It is a comment, an acknowledgment, a statement that focuses on effort, improvement or choice. Hearing "You are so smart!" can leave a child at a loss when they don't do well in a test. Using "That took a lot of work to come home with an A in your test …" gives a child the chance to be something else.

    Almost every light comedy or situation comedy makes me feel like I should be drinking wine every night with my best friend while one of us tries on clothes. Not only should we share the same dress size, but we should also have a long, rich history of togetherness and secrets. Clearly, this is not reality.

    I have 598 friends. OK, but if I'm honest, 99.3 percent of those friends are those I met only once or acquaintances who live too far away to see regularly. That leaves 4 people, who I can call anytime, not feeling like I'm absolutely wasting their time. The remaining 0.2, I've decided, is my houseplant. I can tell it anything.

    Feeling the same way? You're absolutely not alone. Most of us find our "people" in school, but over time life changes: marriage, kids, etc. We grow out of our relationships and they grow out of us.

    So when the relationships come to an end, how do you find a new one?

    A woman in my apartment building, who I had seen around over the years, approached me one day and introduced herself. She bravely stated, "You seem cool. Do you want to hang out with me sometime? I'm looking for new friends." I almost dropped my bag of groceries at her social honesty. And now we get together for coffee a few times a year, gossip (八卦) about the neighbors, and take in the mail when one of us is on vacation. But a few times a year isn't enough for me.

    So, what counts as true friendship as you get older? For me, it's feeling comfortable enough to be myself. And if you're like me, it's also trust — not just keeping the secret, but trusting that my life choices aren't their gossip elsewhere.

    “Don't tell anyone”. We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We5re often tempted to “spill the beans"，even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well "become a burden”. This is because people often have an “obsessive and anxious urge to share it with someone”.

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted (受委托的)with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. "Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone,” according to Shah.

    He added that talkative people could let secrets slip out (泄露). But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although bosses publicly praise the broad benefits AI will bring very much, their main interest lies in cutting costs. One European bank asked a technology company to find a way of reducing the staff in its operations department from 50,000 to 500. This special report has shown that AI-enhanced tools can help reduce staff in departments such as customer service and human resources by a large amount. The McKinsey Global Institute finds that by 2030 up to 375m people, or 14% of the global workers in companies or countries, could have their jobs automated away. Bosses will need to decide whether they are prepared to offer and pay for retraining, and whether they will give time off for it. Many companies say they are all for workers developing new skills, but not at the employer's expense.

    A second important question is how to protect privacy as AI spreads. The Internet has already made it possible to track people's digital（数字的）behaviour in extremely small detail. AT will offer even better tools for businesses to monitor consumers(客户) and workers, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised（个性化的）service. But AI probably brings privacy violations (侵犯) that are seen as shocking and morally unacceptable. In the wrong hands, useful technology could be against fair and equal treatment. Countries with a record of the careful watching of a person place, especially by the police or army and human-rights abuses already using AI to monitor political activity. The police around the world will use AI to spot criminals, but may also look on ordinary citizens secretly, in order to discover things or find out information about them. New rules will be needed to ensure agreement on what degree of monitoring is acceptable.

    The third question is about the effect of AI on competition in business. Today many firms are competing to provide AI-enhanced tools to companies. But a technology company that achieves artificial intelligence could race ahead of competitors, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

Teaching Poetry

    No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.

    All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling "interpretation" of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting it.

    I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn't time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is "a criticism of life", and "a heightening of life". It is "an approach to the truth of feeling", and it "can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies.

    I am not saying that every English teacher must teach poetry. Those who don't like it should not be forced to communicate this to anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.

    It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited.

    My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But… where was my mobile phone? I had that familiar sinking feeling. Yes, I'd left it at home.

    No mobile phone. I'm sure I'm not alone in feeling anxious, on edge and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience 'nomophobia' (无手机恐惧症), the fear of being out of mobile phone contact.

    That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones.

    It says we check our mobile phones 34 times a day, and that 18-24 year-olds, especially girls, are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.

    Do you have nomophobia?

    • You never turn your phone off

    • You frequently(频繁地) check for texts, missed calls and emails

    • You always take your phone to the bathroom with you

    • You never let the battery run out

    It's funny to think that around 20 years ago the only people with mobile phones would be businessmen carrying their large, plastic 'bricks'. Of course, these days, mobile phones are everywhere. A UN study from this year said there would be more mobile phones than people across the world by the end of 2020.

    And when there are more phones than people in the world, maybe it's time to ask who really is in charge(主管)? Are you in control of your phone, or does your phone control you?

    So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all – still always late!" And we had a great afternoon catching up, full of jokes and stories, with no desire(欲望) to check my phone.

    Not having it with me felt strangely free. Maybe I'll leave it at home on purpose next time.

    Science is finaly beginning to embrace animals who were, for a long time, considered second-class citizens.

    As Annie Potts of Canterbury University has noted, chickens distinguish among one hundred chicken faces and recognize familiar individuals even after months of separation. When given problems to solve, they reason: hens trained to pick colored buttons sometimes choose to give up an immediate food reward for a slightly later (and better) one. Healthy hens may aid friends, and mourn when those friend die.

    Pigs respond meaningful to human symbols. When a research team led by Candace Croney at Penn State University carried wooden blocks marked with X and O symbols around pigs, only the O carriers offered food to the animals. The pigs soon ignored the X carriers in favor of the O's. Then the team switched from real-life objects to T-shirts printed with X or O symbols. Still, the pigs walked only toward the O-shirted people: they had transferred their knowledge to a two-dimensional format, a not inconsiderable feat of reasoning.

    I've been guilty of prejudiced expectations, myself. At the start of my career almost four decades ago, I was firmly convinced that monkeys and apes out-think and out-feel other animals. They're other primates(灵长目动物), after all, animals from our own mammalian(哺乳动物的) class. Fairly soon, I came to see that along with our closest living relatives, whales too are masters of cultural learning, and elephants express profound joy and mourning with their social companions. Long-term studies in the wild on these mammals helped to fuel a viewpoint shift in our society: the public no longer so easily accepts monkeys made to undergo painful procedure kin laboratories, elephants forced to perform in circuses, and dolphins kept in small tanks at theme parks.

    Over time, though, as I began to broaden out even further and explore the inner lives of fish, chickens, pigs, goats, and cows, I started to wonder: Will the new science of "food animals" bring an ethical (伦理的) revolution in terms of who we eat? In other words, will our ethics start to catch up with the development of our science?

    Animal activists are already there, of course, committed to not eating these animals. But what about the rest of us? Can paying attention to the thinking and feeling of these animals lead us to make changes in who we eat?

    After years of observing human nature, I have decided that two qualities make the difference between men of great achievement and men of average performance curiosity and discontent. I have never known an outstanding man who lacked either. And I have never known an average man who had both. The two belong together.

    Together, these deep human urges (驱策力) count for much more that ambition. Galileo was not merely ambitious when he dropped objects of varying weights from the Leaning Tower at Pisa and timed their fall to the ground. Like Galileo, all the great names in history were curious and asked in discontent, "Why? Why? Why?"

Fortunately, curiosity and discontent don't have to be learned. We are born with them and need only recapture them.

    "The great man," said Mencius (孟子), "is he who does not lose his child's heart." Yet most of us do lose it. We stop asking questions. We stop challenging custom. We just follow the crowd. And the crowd desires restful average. It encourages us to occupy our own little corner, to avoid foolish leaps into the dark, to be satisfied.

    Most of us meet new people, and new ideas, with hesitation. But once having met and liked them, we think how terrible it would have been, had we missed the chance. We will probably have to force ourselves to waken our curiosity and discontent and keep them awake.

    How should you start? Modestly, so as not to become discouraged. I think of one friend who couldn't arrange flowers to satisfy herself. She was curious about how the experts did it. How she is one of the experts, writing books on flower arrangement.

    One way to begin is to answer your own excuses. You haven't any special ability? Most people don't; there are only a few geniuses. You haven't any time? That's good  because it's always the people with no time who get things done. Harriet Stowe, mother of six, wrote parts of Uncle Tom's Cabin while cooking. You're too old? Remember that Thomas Costain was 57 when he published his first novel, and that Grandma Moses showed her first pictures when she was 78.

    However you start, remember there is no better time to start than right now, for you'll never be more alive than you are at this moment.

    At the age of 83, I'm reading more and dusting less. I'm sitting in the yard and admiring the view without caring about the weeds in the garden. I'm spending more time with my family and friends and less time working.

    Whenever possible, life should be a pattern of experiences to savor, not to suffer. I'm trying to recognize these moments now and cherish them.

    I'm not "saving" anything; we use our good china and crystal for every special event such as losing a pound, or the first Amaryllis blossom. I wear my good clothes to the market. I'm not saving my good perfume for special parties, but wearing it for clerks in the hardware store and tellers at the bank.

    "Someday" and "one of these days" are losing their positions in my vocabulary. If it's worth seeing or hearing or doing, I want to see and do it now.

I'm not sure what others would have done had they known they wouldn't be here for the tomorrow that we all take for granted. I think they would have called family members and a few close friends. They might have called a few former friends to apologize and mend fences for past quarrels. I like to think they would have gone out for a Chinese dinner or for whatever their favorite food was.

    It's those little things left undone that would make me angry if I knew my hours were limited. Angry because I hadn't written certain letters that I intended to write one of these days. Angry and sorry that I didn't tell my husband and parents often enough how much I truly love them. I'm trying very hard not to put off, hold back, or save anything that would add laughter and luster to our lives. And every morning when I open my eyes, I tell myself that it is special. Every day, every minute, every breath truly is a gift.

Throwing away unwanted food has become a big issue in the world. While some of us throw away unwanted items, people in other parts of the world face food shortages and are starving. It's a shocking fact that a third of the world's food is wasted each year, which is enough to feed a billion hungry people.

You may think supermarkets are the main contributors to this mountain of food. After all, they do desert stuff that is past its sell-by-date and they often refuse to sell fruits or vegetables that are in the wrong shape or look damaged. They've also been criticized for encouraging customers to buy more than they need through promotions such as "buy one and get one free".

But the biggest culprit for creating food waste is us human beings. In Europe, an incredible 53% of food waste comes from households, which results in 88 million tons of food waste a year. So instead of filling our bellies, our food is filling up landfill sites.

In Denmark, a woman called Selina Juul has been working hard to solve this problem. She moved from Russia many years ago and was amazed to see the abundance of food available in the supermarkets. But despite so much availability, she found that people were buying more than they needed and throwing too much away.

She convinced some supermarkets to stop selling their items in bulk (大量) so that people bought only what they needed. She produced a leftover cookbook and set up an education program in schools, which has helped create a significant 25% reduction in food waste.

Clearly, we need to think twice when we buy something in supermarkets or online, and when we're at home we should make the most of the food we have — using recipes that use up our leftovers or even sharing our remaining food with our friends and neighbors.

I don't post recognizable pictures of my children on social media. I don't use their names. I don't put anything out there that will be really embarrassing for them in later life.

The reason for not posting pictures is that I feel a person's pictures should be his or her own. It's not good for me to push my kids out into the wilds of the Web before they're ready, and understand what it all means.

When the time comes, they're more than welcome to use social media. But for now, I'm happy to give them a degree of separation until they can make a choice for themselves.

This has meant extra efforts on our part when it comes to making sure that kids don't get accidentally caught up in the Internet, because the schools where they learn, like so many others up and down the country, post their pictures to social media.

However, my husband thought I was overanxious and asked me a question about its advantages. And having thought about it for while, I'm not 100 percent sure if there are any.

But I could list the disadvantages: the time it takes to manage an account, often by a teacher, meaning extra work; the unavoidable difficulties in safeguarding.

It's great to see the kids doing their things in schools but my worry is about the use of social media that doesn't give anything back to the kids, and in many ways, just turns them into another way to gain clicks. I want more than that for them.
