They tell us when to get up or when we’re running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body’s own internal clock---have a powerful influence on our health and behaviour. They are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns.

In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music.

The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib（撒小谎） in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end.

“The body clock has a great effect on us all,” says Professor Jim Horne from the Sleep Research Centre at Loughborough University. “Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That’s because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece.”

At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don’t act on your impulse（冲动）, but let it pass instead. You know that to take the action is wrong in some way and that other people will not accept your behavior.

Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.

One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It’s not taboo to talk about fat; it’s taboo to be fat. The “in” look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious(注意形象的) society like the U.S., thin is “in”, fat is “out”.

It’s not surprising, then, that millions of Americans have become obsessed with staying slim and “in shape”. The pursuit of a youthful physical appearance is not, however, the only reason for America’s fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people’s bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising.

1. From the passage we can infer taboo is .

A. a strong desire to do something strange or terrible

B. a crime committed on impulse

C. behavior considered unacceptable in society’s eyes

D. an unfavorable impression left on other people

2. Based on the ideas presented in the passage we can conclude “being fat” in American society.

A. will always remain a taboo

B. is not considered a taboo by most people

C. has been a taboo long before

D. may no longer be a taboo some day

3.The topic of fat is many other taboo subjects.

A. the same as B. different from

C. more boring than D. less often talked about than

4.In the U.S., thin is “in”, fat is “out”, this means .

A. thin is “inside”, fat is “outside”

B. thin is “diligent”, fat is “lazy”

C. thin is “youthful”, fat is “spiritless”

D. thin is “fashionable”, fat is “unfashionable”

5.The main reason the passage gives for why so many Americans are exercising regularly is .

A. their changed life-style

B. their eagerness to stay thin and healthy

Two years ago, when I was an oversea student, I worked early mornings and late nights to pay for my school fees.

One day, I was seriously ill with a very high fever. I had stayed at home for a few days, and I had run out of food. Because I had been in this town just for a short time, I also had no friends nearby who could help. So I went out to get some food. I would have gone to the supermarket, but on this occasion, I went into a small store because it was closer.

I picked up a few items. When I handed them to the shopkeeper, she said, “You are unwell.” “Yes，” I nodded.

She pointed at the salami and bread I was buying and offered, “I can make you a sandwich, so you don’t have to do it yourself’. So, she made the sandwich and asked me to wait a moment. She went in the back room and returned with a bowl of hot soup.

“It will warm you up,” she said with a genuine smile.

What really warmed me up was not the soup, but her kindness. It made me want to be as kind as the shopkeeper who had been kind to me.

Given a piece of paper and some colored pencils, he draws a variety of from his surroundings as well as from his circle. It is not surprising to see a child draw a monster to represent an abusive father, and an _____ to represent a loving and caring mother.

As he graduates to the later stages of childhood bordering on the years, the child learns the complexity of human relations and socialization by with his peers—his friends and schoolmates.

When a child is told he is “uncool”, it can be very painful. He may say he doesn’t care, and even act in ways that are opposite of cool on purpose. But these are simple ways to handle sadness by pretending it’s not there.

Helping a child feel better in school had to be careful. If you say, “Why are you worried about what other children think about you? It doesn’t matter!” Children know that it does matter. Instead, an active way may be best. You could say, “I’m going to do a couple of things for you to help you feel better in school.”

If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class projects. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child’s popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.

There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider “super” .When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.

What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.

I never thought I would have a life-changing experience at Wal-Mart.

Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier.

There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy!

For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, “How's it going?” But he did something different—he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.

I thought it was odd. I have grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don't give any thought to the question and just mumble something back. I could say, “I just found out I have six months to live,” and someone would reply, “Have a great day!”

But that wasn't the end.

He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked at the customers in the eyes. “I sure want to thank you for shopping here today,” he told them. “You have a great day. Bye-bye.”

The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture---and in a place they never expected. They would gather their things and walk out, smiling.

Of course, he did the same to me and I got to know his name, Marty.

Who was that guy? It was as if Sam Walton had come back from the dead and invaded this old guy’s body.

I had never walked away from that shop feeling like that.
