Kids worry about things like grades, tests, their changing bodies, getting along with friends, the goal they missed at the soccer game, or whether they’ll make the team. They may worry about social troubles like cliques (朋党), peer pressure, or whether they’ll be bullied (威吓), teased, or left out.

There are some tips to help your kids handle what’s worrying them as follows.

Find out what’s on their minds. Be available and take an interest in what’s happening at school, on the team, and with your kids’ friends. Take casual opportunities to ask how it’s going. As you listen to stories of a day’s events, be sure to ask about what your kids think and feel about what happened. If your children seem to be worried about something, ask them about it.

Show your care and understanding. Being interested in your children’s concerns shows they’re important to you. It helps your kids feel supported and understood. Reassuring comments can help — but usually only after you’ve heard your children out. Say that you understand their feelings and the problems.

Guide kids to solutions. When your children tell you about a problem, offer to help them. For example, if your son is worried about an upcoming math test, offering to help him study will reduce his concern about it. In most situations, don’t simply jump in and fix the problem for your children. Instead, think it through and come up with possible solutions together. Solve problems with your kids, rather than for them. By taking an active role, kids learn how to handle a problem independently.

Be a good role model. Your response to your own worries can go a long way toward teaching your kids how to deal with everyday challenges. If you’re at a loss or angry when dealing with a to-do list that’s too long, your kids will learn that as the proper response to stress.

Exercise is an important part of a healthy lifestyle. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm of your day.

· Go for a walk on your lunch break. Try to find at least three different ways and change them throughout the week. It might even be possible to find a place to walk inside, for those bad weather days.

· Talk to your employers about improving health at work. Encourage your workers to cycle to and from work. You might also be able to encourage them to set up a gymnasium. Sell the idea by pointing out that doing so will improve productivity (生产率), and make workers happy.

· If you are a student. Go for walks with friends to talk about your studies. Spend some time in the learning resource centre reading about sport, exercise and health. The more you know, the more choices you will have about how to be physically active. Most colleges have sport and exercise programs that students can take part in. Find out which activities are being held, and try those you think you might enjoy. 

21. Workers are advised to cycle to and from work to ________.

A. make themselves realize the importance of health

D. choose the same one all the time 

23. We can learn from the passage that ________.

A. walk is most suitable for those who work indoors

B. one who knows more about health will be healthier

C. exercising with others will be better for one’s health

D. combining exercise with daily work can save time to keep healthy

24. What’s the main idea of the passage?

Domestic online shopping platforms have turned Nov 11 into a shopping carnival in China.In 2015 alone,the sales volume on Alibaba,a domestic online shopping platform,reached 91.2 billion yuan ($13.5 billion) within 24 hours on Nov 11.

But there is a drawback to the shopping carnival.Most,if not all,of the products sold on the day have to be packaged well and sent through couriers.And the proper disposal(处置)of the materials used to package them has become a problem.

According to the State Post Bureau,the number of express deliveries(快递)reached almost 100 million on Nov 11 last year,which means about 100 million boxes were needed to pack the parcels.

How many of those boxes were recycled?There is no national data on that,but several media reports last year said the percentage was quite low.In one interview after another interviews,most respondents said they felt sorry for throwing the boxes away and they would not have done that had they been told how to deal with them properly.Beijing News even quoted a woman as saying that she had more than 20 boxes at home last November and didn’t know what to do with them,yet she did not throw them away because she didn’t want to do “waste” them.

Considering the lack of a garbage sorting system in China,throwing away packaging materials more often than not means disposing of them with kitchen waste.That is not only a waste of recyclable materials but also harmful to the environment.

In this aspect,courier companies could do something.Such companies always need packaging materials,and by offering rewards to consumers who return them,they will reduce not only waste but also their packaging costs.

This model has a successful example:when a consumer places an order for fresh milk in cities like Beijing,he or she pays a certain amount of money above the price of the milk to the supplier,who pays it back after the consumer returns the glass bottle.The recycling or reuse of glass bottles has become standard practice,which courier companies can learn from.

With Nov 11 just a few days away,this recycling or reuse model could help reduce waste in the country.Since China faces an environmental challenge,we cannot afford to waste hundreds of millions of paper boxes any more.

29.The underlined word “drawback” probably means “          ”

A.benefit       B.shortcoming       C.decline       D.shrink

30.The feeling for most interviewees after they threw boxes can be described as           

A.indifferent   B.considerate       C.regretful D.disappointed

31.The successful example is mentioned in order to           

A.call on consumers to return glass bottles.

B.show the reuse of glass bottle is very popular.

C.recommend a standard model to courier companies to follow.

D.ask all companies to handle waste with this method.

32.This passage mainly talks about           

A.how to deal with package boxes.

B.how to package the goods

C.the cause of package waste

D.the lack of garbage sorting systems in China.

How to Build Healthy Interpersonal Relationship

Human beings are social creatures and thrive(茁壮成长) in relationships with others. A healthy part to be a well-rounded, happy individual is engaging in healthy relationships with others. These friendships can provide safe environments in which individuals can thrive and help promote general well-being. _66．__

1．Know your worth.

One of the first steps in building healthy interpersonal relationships is understanding one's value. When an individual is aware of and treasures what he or she has, the building of relationships can be founded on that knowledge. _67．__. Everyone has talents. When this worth is discovered, a person can then make use of these skills in approaching interpersonal relationships. If someone is a good listener, showing how to develop this skill can attract relationships with individuals who have a need for this talent.

2．Recognize the value of others.

__68．__ In a healthy interpersonal relationships, both parties should be respected and feel as if they are valued in the friendship. When contributions to the relationship become one－sided, the relationship will move from healthy to unhealthy.

69．__

Another way to build healthy relationships is to make friends with someone who shares the same value systems and lifestyles. Knowing that a friend will not request something from an individual will help to foster trust in the relationship. _70．__The relationship can grow on this familiarity. Trust can also develop from these similarities and go a long way in fostering a healthy friendship.

A. Also, having the same lifestyle can provide a link of familiarity.

B. A healthy interpersonal relationship cannot be built on dishonesty.

C. Seek out individuals with similar value systems.

D. Be true to yourself.

E. Everyone has worth.

F. Here are some tips to build healthy interpersonal relationships.

G. Along with understanding one's worth is recognizing and understanding the worth of others.

Sir John, a British scientist who won last year’s Nobel Prize for medicine, said he had predicted at the time of his frog experiments that the successful cloning of a mammal would happen within 50 years, and that “maybe the same answer is appropriate” for the step to human cloning. Parents who lose children in accidents may be able to clone “copies” to replace them then.

Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful. Cloning was regarded with extreme doubts when it was first developed but became widely accepted after the birth of Louise Brown, the first “test tube baby”. He said, “When my first frog experiments were done, an American reporter asked how long it will be before these things can be done in mammals or humans. I said, ‘Well, it could be anywhere between 10 years and 100 years—how about 50 years?’ It turned out that it wasn't far off the mark as far as Dolly was concerned. Maybe the same answer is appropriate.” Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be “copying what nature has already produced”.

The average vote on allowing parents of deceased children, who are no longer fertile, to create another using the mother's eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 per cent in favor. The reasons for “no” are usually that the new child would feel they were some sort of a replacement for something.

21. Sir John predicted the human cloning would be a reality in ________ at most.

 A. 100 years       B. 60 years         C. 50 years         D. 10 years

22. According to the text, which statement is NOT true?

 A. Louise Brown is the first “test tube baby”.

 B. Human cloning is still a controversial topic.

 C. Sir John is positive about the future of human cloning.

 D. Human cloning is creating something that didn't exist before.

23. What does the text mainly talk about?

 A. The life of Sir John.                       B. Prediction on human cloning.

 C. Views on human cloning.                   D. Achievements in human cloning.

It is good to make mistakes, and here's why.

66． It's always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve, bow can you expand, and how can you innovate? The simple answer is “You can't”. 67． With very few exceptions, everything you see in your physical world is The result of someone trying something new. Every single detail of every single thing is the result of someone trying something new. The chair you're sitting on; the fabric on the chair; the pattern on the fabric on the chair; the dye in the pattern on the fabric on the chair are all the direct result of someone trying something new.

68．_Consider this: Edison failed l0 000 times before he perfected the light bulb. When asked how it felt to fail that many times, he remarked that he hadn't failed t0 00~ times, but rather had learned I0 000

things that didn't work.

Finally, when you make a mistake you are that much closer to success. Why?

Because when all is said and done, you will have tried some finite number of things before you succeed.

69． _

_70．_ Quite the contrary, when you try something new you have to be willing to set some reasonable limits so that, in the event that it doesn't work out the way you want it to, you will be in a position to try again.

There is an old axiom that goes, “if you're not making mistakes, you're not trying hard enough.”

So go forth and make mistakes, and learn, and grow, and prosper.

A. Look around you.

B. First of all, mistakes are a clear sign that you are trying new things.

C. Every time you made a mistake you eliminated one of those things and are one step closer.

D. Another good thing about mistakes is this: when you are making mistakes, you are learning.

E. But this all doesn't mean that you should forge ahead with disregard for the consequences of a mistake.

F. Only by embracing and using your mistakes in this way can you make significant advances in your business and your career.

G. Can you imagine how many mistakes were made before all of these individual materials and components were perfected and then assembled into the automobiles we know today?

__ many times, but she still didn't know how to do it.

A. She was taught B. Having taught C. Having been taught D. She has taught

Scientists have never known for sure whether dinosaurs were warm-blooded animals, like mammals and birds, or cold-blooded, like reptiles and fish. A recent study shows that in fact many dinosaurs might not have belonged to either category but instead have fallen somewhere in the middle.

Warm-blooded animals have bodies that are able to make their own heat. Their body temperatures stay about the same whether it is hot or cold outside. Cold-blooded animals can not make their own heat, so their body temperatures depend on how warm the outside temperature is. Warm-blooded animals have much more active lifestyles than cold-blooded ones.

When scientists first discovered the bones of ancient dinosaurs in the 1800s, they were sure the huge creatures must have been slow. But as scientists found more bones of smaller, quicker dinosaurs, like Velociraptor, they realized that the creatures may have been much more active than they had thought.

A team of biologists began to examine. They knew that warm-blooded animals grow faster than cold-blooded ones. The researcher realized that they could determine whether a dinosaur had been warm-or cold-blooded by finding its growth rate.

The scientists examine the growth rings in bones from 21 different dinosaur species. The width of the growth rings showed how much the dinosaurs grew each year, much like the rings in the tree trunk do.

“Our results showed that dinosaurs had growth rates that were actually not characteristic of warm-blooded or cold-blooded animals,” said Brian Enquist, a scientist on the research team. “They didn’t act like mammals or birds, nor did they act like reptiles or fish.” Instead, dinosaurs fell somewhere in between. Scientists called the middle-of-the-road creatures “mesotherms”.

Being mesotherms gave dinosaurs many advantages. They were faster and stronger than reptiles that had to rely on the sun for warmth. Being somewhat cold-blooded had its benefits too. Cold-blooded animals bum energy more slowly. So they need much less food to live than warm-blooded animals. “It is doubtful that a lion size of T-rex could eat enough to survive,” explains John Grady, another biologist on the research team. By being mesothermic, the dinosaurs could be both fast and big.

12. What is Paragraph 2 mainly about?

A. The advantage of cold-blooded animals.

    B. The disadvantages of warm-blooded animals.

    C. The differences between warm-and cold-blooded animals.

    D. The advantages of both warm-and cold-blooded animals.

13. It can be inferred that mesotherms grow _______.

    A. as slowly as cold-blooded animals      B. as fast as warm-blooded animals

    C. slower than cold-blooded animals      D. slower than warm-blooded animals

14. A lion is mentioned in the last paragraph to stress that ________.

    A. dinonsaurs moved very fast           B. dinonaurs are large animals

    C. dinosaurs needed less food to survive   D. dinosaurs had to rely on the sun for warmth

15. The text is mainly about ________.

    A. how dinosaurs disappeared

    B. the growth areas of dinosaurs

    C. the appearance and behavior of dinosaurs

    D. if dinosaurs were warm-or cold-blooded animals

        Zebra crossings - the alternating dark and light stripes on the road surface - are meant t。

remind drivers that pedestrians may be trying to get across. Unfortunately, they are not very

effective. A 1998 study done by the Department of Traffic Planning and Engineering at Sweden's

 Lund Univers ity revealed that three out of four drivers maintained the same speed or even speeded up as they were approaching a crossing. Even worse? Only 5% stopped even when they saw someone trying to get across.

       Now a mother-daughter team in Ahmedabad, India has come up with a clever way to get

 drivers to pay more attention - A 3-D zebra crossing with an optical illusion  (视错觉)  .

        Artists Saumya Pandya Thakkar and Shakuntala Pandya were asked to paint the crosswalks by IL&FS, an Indian company that manages the highways in Ahmedabad. The corporation was looking for a creative solution to help the city's residents to cross the busy accident-prone  (易出事故的)  roads safely. Thakkar and Pandya, who had previously seen images of3-D zebra crossings that gave drivers the illusion of logs(原木)of wood on the streets in Taizhou, China, decided to test if a similar way would work in India.

       Sure enough, in the six months that the 3-D crosswalks have been painted across four of the city's most dangerous highways, there have been no accidents reported! The artists say that while it may appear that the zebra crossing could cause the drivers to brake suddenly and endanger the vehicles behind, such is not the case. Because of the way the human eye works, the illusion is only visible from a distance. As they get closer, the painting looks just like any other ordinary zebra

  crossing. The creators hope that their smart design will become increasingly common throughout

  India and perhaps even the world. So let's look for ward to it.

32.  What can we learn from the first paragraph?

    A.  Most drivers will slow down at zebra crossings

    B  Common zebra crossings don't function well

    C  Drivers have to stop when approaching zebra crossings

    D.  About 95% of the drivers choose to speed up when approaching zebra crossings

33.  Why do drivers seeing the 3-D zebra crossings slow down?

    A.  Because the drivers consider the safety of pedestrians

    B  Because the drivers mistake them for logs of wood On the streets

    C.  Because the drivers are afraid of being fined for breaking the traffic rules

    D.  Because the drivers don't want to brake suddenly and endanger the vehicles behind

34.  The last paragraph is mainly about____

    A.   the theory of the 3-D zebra crossings

    B.   the popularity of the 3-D zebra crossings

    C.   the shortcoming of the 3-D zebra crossings

    D.   the positive effect of the 3-D zebra crossings

35.  What is the author's attitude towards the 3-D zebra crossings?

    A. Cautious    B  Doubtful    C. Approving    D. Disapproving

Dear Diary,

Here I am in the middle of a city, 350 miles far away from our farmhouse. Do you want to know why we move last week? Dad lost his job, and as Mom explained, “He was lucky to find other one.” His new job meant I had to say goodbye to my classmate, my school or just everything else I love in the world. To make matters bad, now I have to share a room with my younger sister, Maggie. Tomorrow is first day of school. I am awfully tiring, but I know I will never fall sleep.

Good night and remember, you, dear diary, is my only souvenir from my past life and my only friend.

Yours,

Rosemary

Tip for Chinese Students Studying Abroad

As living conditions in China are getting better, parents who want their children to have a bright future invest large sums of money to send their children to study abroad. However, there are countless difficulties that students have to face and solve when they study abroad. Therefore it is necessary for Chinese overseas students to be aware of certain things to which they must pay attention.

61. ______

Safety issues before and after studying abroad have been one of the focuses of parents. However, all experts consider psychological preparation as the most important thing for students studying abroad to consider. They believe that students must have a clear picture of their position and know that they are going abroad to study and receive training and not for leisure. And they should not have the opinion that everything abroad is good and all things from China are bad. Students should prepare themselves for the differences.

62. ______

Chinese students have got accustomed to the domestic exam-oriented education style that is completely different from the more open foreign education mode. They will face changes in the educational system while studying abroad. So students should learn about the differences between the domestic and foreign education styles and try to find more solutions to adjusting to the open education in order to be well prepared for their overseas studies both mentally and practically.

63. ______

Students should ask related teachers to help make plans consistent with their practical condition. There should be both macro and detailed learning plans. Macro learning plans require students to hold on to the primary direction of their overseas studies and detailed learning plans require them to arrange learning content for each course and semester. After the plan is made, they should strictly keep to them. Otherwise, the plan will have no effect.

64. ______

As Chinese students are not familiar with the place and people, and have no relatives by their sides, the first feeling they will feel is loneliness, which makes it especially important to learn to develop relationships with people around them. They may meet all kinds of fascinating people abroad. They should go out of their way to be friendly and strike up conversations. The most important thing is to pluck up enough courage to open your mouth and talk with others. Foreigners really like children of this kind and are willing to help them.

65. ______

Foreign children are used to learning by themselves in or after class, but Chinese children are used to teacher-centered education. Guided and supervised by parents and teachers, Chinese students don’t have much learning space. They may score high in exams, but they may lack independent learning skills and tend to be in a state of passive learning. So the most basic thing that children need to know is that studying abroad requires that they should adapt to overseas studies as soon as possible and try their best to learn actively and independently.

Dear Sir，

     Thank you for invite me to the summer English course in your school. As for your choice between the two courses, I prefer the four-week course because of this will allow me more time to do some traveling but make a few new friends. Of all the subject I’m learning at school, I like English best. I had been learning English for eleven years but my spoken English remains poorly. So I really hope to take this chance improve it. If possible, I’d like to stay with a family for a couple of days in order that I can know some customs in England, that I’m particularly interested in. I believe I will have wonderful time this summer.

Chinese kungfu is one of the earliest and longest-lasting sports that use both muscle and brain. Over its long history it has developed as a unique combination of exercise, practical self-defense, self-discipline and art.

It is estimated that Chinese kungfu can date back to primitive society. At that time, people used sticks to fight wild beasts. Gradually, they accumulated a great deal of self-defense experience. When the Shang Dynasty began, hunting was considered an important part of kungfu training .

During the Shang and Zhou dynasties, martial arts(武术) evolved to become a kind of dancing. Usually, the dancing of martial arts was used to train soldiers and inspire their morale. At the same time, the skill and technology of sword making as well as sword ceremonies developed rapidly.

Starting from the Tang Dynasty, a kungfu examination was proposed and introduced. Excellent candidates would receive titles and awards through the examination, largely promoting the development of martial arts. By then, martial arts had evolved to become an art form and an independent genre. Kungfu was gradually introduced to many countries in Southeast Asia. Today , kungfu is honored as the ancestor of kickboxing(跆拳道), karate(空手道) and judo.

The Song and Yuan dynasties witnessed the climax of kungfu development. The practice of kungfu by civil organizations became more and more popular. People actually made a living as martial arts performers all over the country. Usually their performance was carried out by a single person or two people as a pair.

Chinese kungfu achieved greater development in the Ming and Qing dynasties. In the Ming Dynasty, a lot of genres came into being and numerous books on martial arts were published. In the Qing Dynasty, the ruling empire banned the practice of martial arts, and the people had to set up various clubs or societies to pass on the skills in secret.

Today, kungfu continues to be practiced by many people for the purpose of keeping fit or improving body image.

Chaco Great House

As early as the twelfth century A.D., the settlements of Chaco Canyon in New Mexico in the American Southwest were notable for their "great houses," massive stone buildings that contain hundreds of rooms and often stand three or four stories high. Archaeologists have been trying to determine how the buildings were used. While there is still no universally agreed upon explanation, there are three competing theories. 

One theory holds that the Chaco structures were purely residential, with each housing hundreds of people. Supporters of this theory have interpreted Chaco great houses as earlier versions of the architecture seen in more recent Southwest societies. In particular, the Chaco houses appear strikingly similar to the large, well-known "apartment buildings" at Taos, New Mexico, in which many people have been living for centuries. 

A second theory contends that the Chaco structures were usedto store food supplies. One of the main crops of the Chaco people was grain maize, which could be stored for long periods of time without spoiling and could serve as a long-lasting supply of food. The supplies of maize had to be stored somewhere, and the size of the great houses would make them very suitable for the purpose. 

A third theory proposes that houses were used as ceremonial centers. Close to one house, called Pueblo Alto, archaeologists identified an enormous mound formed by a pile of old material. Excavations of the mound revealed deposits containing a surprisingly large number of broken pots. This finding has been interpreted as evidence that people gathered at Pueblo Alto for special ceremonies. At the ceremonies, they ate festive meals and then discarded the pots in which the meals had been prepared or served. Such ceremonies have been documented for other Native American cultures.
