Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

    Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

    Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important part in keeping you healthy.

    Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

    Zhou Yan is the Senior Three student. Last week, he goes to see a doctor because of his arms and fingers hurt. The doctor told him the fact that had a “mobile phone disease”. Zhou sent messages for his friends with his mobile phone all the time, even in bed. Zhou started to do badly in all the exam last term because he spent so many time on his mobile phone. He didn't stop use the mobile phone until his arms hurt. Yang Ling, which is an expert from a health center, said students should try to use their mobile phones less, especial at school.

    When we read books we seem to enter a new world. This new world can be similar to the one we are living in, or it can be very  1 . Some stories are told 2 they were true. Real people who live in a 3 world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not 4. They are characters and creatures that are very different from us and do things that would be 5 for us.

But there is more to books and writing than this. If we think about it, even realistic writing is only 6. How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we 7 seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than 8. Reading, like writing, is an action. It is a way of 9. When we read or write something, we do much more than simple look at words on a page. We use our 10 --which is real—and our imagination—which is real in a different way — to make the words come to life in our minds.

    Both realism and fantasy(幻想) 11 the imagination and the "magic" of reading and writing to make us think. When we read 12realistic, we have to imagine that the people we are reading about are just like us, even though we13 that we are real and they are14. It sounds 15, but it works. When we read, we fill in missing information and16 about the causes and effects of what a character does. We help the writer by 17 that what we read is like real life. In a way, we are writing the book, too.

    Most of us probably don't think about what is going on in our 18 when we are reading. We pick up a book and lose 19 in a good story, eager to find out what will happen next. Knowing how we feel 20we read can help us become better readers, and it will help us discover more about the real magic of books.

    March 8 marks the annual International Women's Day. Around the world, women usually played a not well-known role in history. They were often buried with their unknown talents and amazing tales. Yet there are still some lucky ones whose stories have been recorded. Here are six talented ancient Chinese women who once impressed in their time, and still affect us in our time.

    Praised as the “No.1 talented woman”, Li Qingzhao, a poet from the Song Dynasty, was born in Shandong province. She excelled at poetry and in ink painting and calligraphy (书法). Li was most well-known for her poems, which were divided into two contrasting styles reflecting her life as a married woman and a widow. Before her husband's death, her poems were mainly about a carefree and happy life. The keynote turned into a sad tune after her husband passed away. However, Li was not a narrow-minded woman. Apart from expressing feminine (女性的) feelings and experiences, she also wrote poems praising war heroes and criticizing the corrupted emperor. As an example of female patriot, Li has a great effect on modern women's literature.

    Cai Wenji was good not only at poetry and calligraphy, but also mathematics, astronomy, debate and music. Her masterpieces were Hu Jia Shi Ba Pai. As the daughter of literatus Cai Yi of the Eastern Han Dynasty, Cai had a very unusual life. After her first husband died, she was forced to marry Xiongnu tribe's king. Living in a totally different environment, Cai was very homesick. Twelve years later, Cao Cao, a student of Cai Yi, rescued Cai from the Xiongnu tribe. At the age of 35, Cai got married for a third time in a union arranged by Cao to a man named Dong Si.

    Ban Zhao was the first female historian in China. She was also good at writing poems, yet only seven of her works have survived. Ban was often invited by the emperor to teach the queen mathematics, astronomy and poetry. She was honored as Da Gu, a title for knowledgeable and noble women. At the age of 40, Ban finished Han Shu, based on her brother's writings. A total of four people wrote the book, and Ban, as the last writer, faithfully kept the style of the first three. Ban Zhao also wrote Nv Jie, a book to teach women how to deal with relationships with their husbands and husbands' relatives and how to properly behave.

    Shangguan Wan'er was famous for being given an important position by the only female emperor, Wu Zetian of the Tang Dynasty. Despite Shangguan's grandfather being killed for offending Wu, she was highly praised by the female emperor for her literary talent. She served as a key secretary to Wu and was called “a female prime minister” at the time. Shangguan changed court poetry so that it used more meaningful expressions than empty praise, and further developed her style based on her grandfather's poems.

    Su Hui was known for a handkerchief she made. It was embroidered (刺绣) with 841 characters that could form 7,958 poems. Named Xuan Ji Tu, the handkerchief was originally made by Su to send to her husband, Dou Tao. Su waited for her husband to come back after Dou's exile (流放), yet Dou had an affair with another woman. Sad and angry, Su created the poems on a handkerchief in red, yellow, blue, white, black and purple silk thread and sent it to her husband. Dou was deeply moved by the poems, felt guilty for his behavior and reunited with Su.

    When Xue Tao's name was mentioned, people would think of the famous Xue Tao Jian, a sort of small-size colorful writing paper. It is recorded that Xue Tao created this colored paper to write poems. During her time, writing paper was yellow, yet Xue changed the simple color into different shades of red or green. Later, people made similar colorful paper and named them “Xue Tao Jian”. Xue had talent for poetry and music. Her poems were not limited to those private feminine feelings and emotions; she also expressed her empathy (共鸣) to soldiers on the frontier.

Everybody knows that Coca Cola is red and Starbucks is green. Most of us can name companies and their own brand colors. What we may not know about is the science behind these companies' choices of these colors. Color psychology is the study of how colors affect people's feelings, actions, and decision-making. Companies use color psychology when they develop their brands and advertisements in order to encourage us to buy. In fact studies have shown that around 90 percent of people spend money depending on color and appearance. Because of this, companies use colors to influence how we feel about their products. For example, it's no accident that many tech products use white; it's simple and clean. At the same time, cosmetics companies prefer colors like purple, black, or pink that mean love, comfort, and romance.

Companies often choose active colors that make you buy right now. Red, for example, is a high-energy, exciting color that moves people to take action. Yellow is the color of summer, and it's bright and remarkable. In fact, most big companies have something to do with certain specific colors. Studies show that customers prefer brands that they know. Then those with a proper color plan, such as LEGO or Facebook are likely to perform more strongly on the market. Research has also shown that men and women like different colors. Men prefer blue, green, and black while women prefer like purple and pink.

A friend of mine is a musician. He always seems to be learning new tunes, new 1, and new ways of making music in cool ways. At the weekends, he 2 to go into Central Park in the center of Nagoya during the daytime where lots of bands 3. Some of these bands are really good, but some of them are quite 4.One of the reasons why my friend likes watching all the bands is that they are free! And as he says to me, "5 expensive things don't necessarily mean that they're good, free things don't necessarily mean they have no 6.You have to listen and look yourself and7what is valuable for you. And 8, as you listen and look, you may learn different things."

So my friend goes to the park every week when the weather is fine, and he says he learns9 from every single band！ When he watches and listens to the really good bands, he learns new concertos from the 10 and cool rhythms from the drummers. I guess that it's not 11that you can learn a lot by watching 12performs. But what impress me are my friend's words—You can learn by watching and listening to the bad performers, too. When I watch a bad performer, I think to myself — wow, that's another thing that I'm going to 13."

So my friend makes 14 by leaning from both good and bad performers. And he says he also finds 15and pleasure in learning and improving in ways that he never even imagined!

—Well, __________. But it was you who didn't keep your word first.

    Mass media are tools of communication.Mass media allow us to record and pass information rapidly to a large，scattered(分散的)audience.They extend our ability to talk to each other by helping us overcome barriers caused by time and space.

    There are various ways in which mass media make daily life easier for us.

    First,they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to get on our own.

    Second，mass media help us to arrange our time and life.  What we talk about and what we think about are greatly influenced by the media.When people get together，they tend to talk about certain happenings in the newspapers or on TV.Because we are exposed(暴露)to different points of view through different kinds of media every day，we are able to evaluate(评价)all sides of a certain issue.

    Third,the media are used to persuade people. A good example is advertising through the media.Newspapers，magazines and TV are filled with all kinds of colorful，persuasive advertisements.Though many advertising may not say openly that they want you to buy a certain product，they describe their products in such a way that you may want to buy them.

    Fourth,the media also entertain.  All of the media make some efforts to entertain their audience.For instance，even though the newspaper is primarily a medium of information，it also contains entertainment features(特征)．Television，motion pictures，fiction books and some radio stations and magazines are devoted mainly to entertainment.It is estimated that in the future，the entertainment function of mass media will become even more important than it is now.

    If anyone had told me three years ago that I would be spending most of my weekends camping. I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me.

    The friends who introduced me to camping thought that it meant to be a pioneer.  We sleep in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor's bill for my son's food poisoning.

    I was, nevertheless, talked into going on another fun-filled holiday in the wilderness. Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.

     We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.

     It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.

A.This time there was no tent.

B.Things are going to be improved.

C.The trip they took me on was a rough one.

D.I was to learn a lot about camping since then, however.

E.I must say that I have certainly come to enjoy camping.

F. After the trip, my family became quite interested in camping.

G. There was no shade as the trees were no more than 3 feet tall.

It's difficult to imagine now, but at certain points in the Earth's history, ice covered the entire planet. This frozen Earth, nicknamed Snowball Earth, was "so severe that the Earth's entire surface, from pole to pole, including the oceans, completely froze over", said Melissa Hage, an environmental scientist at Emory University in Georgia.

In 1840, Louis Agassiz, a Swiss natural scientist, was among the first to acknowledge and provide evidence that the Earth had gone through ice ages. Joseph Kirschvink, an American geologist, later created the term "Snowball Earth" in a 1992 textbook.

Scientists believe that four severe ice ages occurred between 750 million and 580 million years ago, probably because the Earth's lands were all located at or near the equator (赤道), which resulted in increased weathering (风化). Weathering is happening when wind and rain break down rocks and minerals on the planets surface. The rocess leads to decreased carbon dioxide levels in the atmosphere, which allows more heat to get away from the surface and into space, cooling the planet, causing the planet into a deep freeze.

The severe ice ages eventually melted away. Scientist believe that volcanoes continued to pump carbon dioxide into the atmosphere throughout the ice ages, eventually warming the planet enough that the water cycle could restart. As the Earth warmed and came out of its deep freeze. a huge explosion of life occurred. known as the Cambrian (寒武纪) explosion.

Will we see another Snowball Earth in our future? According to Hage, it's unlikely, due to the spread-out of the continents. "Even with extreme winters, continental ice sheets would form, which would stop continental weathering and allow carbon dioxide to build up in the atmosphere, leading to warming rather than freezing," she said.
