One way that scientists (科学家) learn about man is by studying animals．In this lab, the scientists are studying the relationship between diet and health．
They are studying the relationship between the amount (数量) of food the mice eat and their health．The mice are in three groups．All three groups are receiving the same healthy food．The first group is eating one cup of food each day, the second group is eating two cups, and the third group is eating three cups．
After three years, the healthiest group is the one that is only eating one cup of food each day．The mice in this group are a little thinner. But they are more active．Most of the day, they are running, playing with one another．Also, they are living longer．Mice usually live for two years．Most of the mice in this group are still alive after three years．
The second group of mice is healthy, too．They are active, but not as active as the thinner mice．They are only living about two years．
The last group of mice is receiving more food than the other two groups．Most of the day, these mice are eating or sleeping．They are not very active．These mice are living longer than the scientists thought－about a year and a half．But they are not healthy．They are sick more often than the other two groups．People give each group of the mice _______ amount of food every year.
| A．a different | B．the same |
| C．a small | D．a large |
The experiment (实验) lasted for at least _______ years．
| A．one and a half | B．two |

The best title for the passage is ________．
| A．Man and health | B．Diet and animals |
| C．Diet and health | D．Animals and human beings |
The result of the experiment mainly shows that ________．
| A．eating less may bring longer life |
| B．the mice eat more than the scientists thought |
| C．the mice live longer than the scientists thought |
| D．the more exercise you take, the healthier you will be |
Have you ever heard your own voice? “Of course,” you say. Has anyone else ever heard your voice? Again you say, “Of course.”But that’s not quite true. Nobody else has ever heard your voice—the way you hear it. When you talk, you set up sound waves(声波). The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones(骨头) of your head pick up the sound waves, too. They carry the sound waves straight to your inner(里面的) ears. You get the sound from the outside and the inside too. Other people get just the sound waves from the outside. That’s why they don’t hear your voice the way you do.The sound of your voice begins ________.
| A．inside your head | B．outside your head |
| C．in your inner ears | D．in your outer ears |
When you talk, other people hear your voice _______.

Once there was something wrong with a machine in a factory. The workers could do nothing but turn to a German engineer for help, who drew a line on it and then said, “Take off the part where the line is and change it for a new one. ”The machine, with a new line on, began running well again. The engineer then asked for $30,000 for what he had done. The following were what he wrote on a bill, “The new part only costs one dollar, and knowing where the problem with the machine is costs $29,999.”

“How are you?” is a nice question. It’s a friendly question that people in the U.S.A use to greet each other. But “How are you?” is also a very unusual question. The person who asks “How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are simply other ways of saying “Hello” or “Hi”.
Sometimes, people also don’t say exactly what they mean. For example, when someone asks “Do you agree?” the other person might think, “No, I disagree. I think you’re wrong...”But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person say “I’ve to go now.” Often, the person who wants to hang up gives an excuse: “Someone’s at the door.” “Something is burning on the stove.” The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt the other person.
When they are greeting each other, talking about an idea or finishing a talk, people don’t say exactly what they are thinking. They are trying to be nice to each other, and it’s part of the game of language.When a person in America asks “How are you?”, he or she wants to hear “_____”.
| A．How are you? | B．Hello |
| C．I don’t know | D．Fine |
When a person disagrees with someone, it is polite to say “_____”
| A．I think you are wrong. | B．I’m not sure. |
| C．I agree | D．No, I disagree. |
When a person says “I’ve to go now. Someone is at the door.” he or she may be _____.
| A．giving an excuse | B．ill |
| C．hurting someone’s feeling | D．asking a question |
The rule of the game of language is probably _____.
| A．“Always say what you mean” |
| B．“Don’t disagree with others” |
| C．“Never ask questions ” |
| D．“Be polite” |
When I was a kid in Minnesota, watermelon was expensive. One of my father’s friends, Bernie, was a rich businessman, who owned a large store in St. Paul.
Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie’s place. We’ d sit on the edge of the dock（码头）, feet dangling（摇晃）, and got ready for a big meal.
Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we’d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.
Bernie was my father’s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie’s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.
What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don’t take the time to dangle your feet over the dock and enjoy life’s small pleasure, your work is probably hurting your life.
For many years, I forgot that lesson I’d learned as a kid on the loading dock. I was too busy making all the money I could.
Well, I’ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That’s the heart of the watermelon. I have learned again to throw the rest away.We learned from the second paragraph that the writer and his father were feeling ______.

We recycle(回收利用) rubbish, so why not language? Recycling language means using vocabulary that you have learnt before again and again. However, unlike rubbish that piles up(堆积)in our environment, if we do not recycle language, we simply forget it. So how do you recycle language?
There are basically three ways to do it. The first is through reading. Go back to your favourite articles and read them once more. Just reread them and do not worry about each vocabulary item. If there are some that you are not sure about, make a guess and you will probably guess right. The second way to recycle is through writing. Look at some of your favourite articles and write either a short paragraph or a few sentences in your own words. After you have done this a few times, go back and read through what you have written, checking vocabulary functions. Don't worry if you have made mistakes. That's how you learn. The third way to recycle language is by having an imaginary chat with yourself about your favourite articles at home. You can pretend there is someone with you who speaks English and tell him what you are thinking about or how you feel.According to the passage, recycling language means ______.
| A．repeating vocabulary at times |
| B．revising vocabulary at a proper time |
| C．learning new vocabulary as much as possible |
| D．using vocabulary that we have learnt very often |
If we recycle language, it may ______.
| A．be kept in our mind |
| B．be forgotten easily |
| C．pile up in our environment |
| D．disappear from our mind soon |
The second way to recycle language tells us to .
| A．rewrite our favourite articles. |
| B．pay more attention to mistakes |
| C．practise spoken English with someone |
| D．pay no attention to vocabulary functions |
Which of the following is NOT mentioned in recycling language?
| A．Reading. | B．Listening. |
| C．Writing. | D．Speaking. |
Which of the following is probably the best title of the passage?
