B
It was 1961 and I was in the fifth grade. My marks in school were miserable and, the thing was, I didn’t know enough to really care. My older bother and I lived with Mom in a dingy multi-family house in Detroit. We watched TV every night. The background noise of our lives was gunfire and horses’ hoofs from “Wagon Train” or “Cheyenne”, and laughter from “I Love Lucy”, or “Mister Ed”. After supper, we’d sprawl on Mon’s bed and stare for hours at the tube.
But one day Mom changed our world forever. She turned off the TV. Our mother had only been able to get through third grade. But, she was much brighter and smarter than we boys know at the time. She had noticed something in the suburban houses she cleaned books. So she came home one day, snapped off the TV, sat us down and explained that her sons were going to make something of themselves. “You boys are going to read two books every week,” she said. “And you’re going to write a report on what you read.”
We moaned and complained about how unfair it was. Besides, we didn’t have any books in the house other than Mom’s Bible. But she explained that we would go where the books were: “I’ll drive you to the library.”
So pretty soon there were these two peevish boys sitting in her white 1959 Oldsmobile on their way to Detroit Public Library. I wandered reluctantly among the children’s books. I loved animals, so when I saw some books that seemed to be about animals, I started leafing through them.
The first book I read clear through was Chip the Dam Builder. It was about beavers. For the first time in my life I was lost in another world. No television program had ever taken me so far away from my surroundings as did this verbal visit to a cold stream in a forest and these animals building a home.
It didn’t dawn on me at the time, but the experience was quite different from watching TV. There were images forming in my mind instead of before my eyes. And I could return to them again and again with the flip of a page.
Soon I began to look forward to visiting this hushed sanctuary form my other world. I moved from animals to plants, and then to rocks. Between the covers of all those books were whole worlds, and I was free to go anywhere in them. Along the way a funny thing happened: I started to know things. Teachers started to notice it too. I got to the point where I couldn’t wait to get home to my books.
Now my older brother is an engineer and I am chief of pediatric neurosurgery at John Hopkins Children’s Center in Baltimore. Sometimes I still can’t believe my life’s journey, from a failing and indifferent student in a Detroit public school to this position, which takes me all over the world to teach and perform critical surgery.
But I know when the journey began the day Mom snapped off the TV set and put us in her Oldsmobile for that drive to the library.
46. We can learn form the beginning of the passage that ___________.
A. the author and his brother had done well in school
B. the author had been very concerned about his school work
C. the author had spent much time watching TV after school
D. the author had realized how important schooling was
47. Which of the following is not true about the author’s family?
A. He came from a middle-class family.
B. He came from a single-parent family.
C. His mother worked as a cleaner.
D. His mother had received little education.
48. The mother was ____________ to make her two sons switch to reading books.
A. hesitant               B. unprepared        C. reluctant                   D. determined
49. How did the two boys feel about going to the library at first?
A. They were afraid                                    B. They were reluctant.
C. They were impatient.                               D. They were eager to go.
50. The author began to love books for the following reasons EXCEPT that ___________.
A. he began to see something in his mind
B. he could visualize what he read in his mind
C. he could go back to read the books again

Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.         
During the hours when you labor through your work you may say that you're “hot”. That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak(高峰). For some people the peak comes before noon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues ( 自言自語(yǔ) ) as: “Get up, John! You'll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and- energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract ( 對(duì)抗 ) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam ( 鼓起干勁 ) and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
小題1:If a person finds getting up early a problem, most probably________.
A.he is a lazy person
B.he refuses to follow his own energy cycle
C.he is not sure when his energy is low
D.he is at his peak in the afternoon or evening
小題2:Which of the following may lead to family quarrels according to the passage?
A.Unawareness of energy cycles.B.Familiar monologues.
C.A change in a family member's energy cycle.
D.Attempts to control the energy cycle of other family members.
小題3:. If one wants to work more efficiently at his low point in the morning, he should________.
A.change his energy cycleB.overcome his laziness
C.get up earlier than usualD.go to bed earlier
小題4:Which of the following statements is NOT true?
A.Getting off to work with a minimum effort helps save one's energy.
B.Dr. Kleitman explains why people reach their peaks at different hours of day.
C.Habits help a person adapt to his own energy cycle.
D.Children have energy cycles, too.

This is a true story about two friends.
One day a young man said to his good friend, "I can see that some day you will become great and rich." His friend laughed, "Ridiculous! How can you know that?" The first said, "Yes, I can see it from your forehead." The second one said, "Ok, if I become great and rich, I will give you 10,000 rupees." The first friend asked. "Really? If so, then write it down."
The second one really wrote it down. The first man kept the note, but he never took his friend seriously. The agreement was made as a joke. 10 or 12 years later, the friend did become rich and great, while the other remained poor. By that time both friends had separated and were leading their own lives. Even so, the poor friend still preserved the note, although he felt that since it was a joke, he would never receive the money.
Quite unexpectedly, the poor man fell seriously ill. Just before he died, he took out the agreement and called his son, who was only seven years old, "My son, there is something very precious that I have kept for you. After I die…you go to this man and show him what he has written."
Soon the man died. Their friendship had faded so much that the rich man did not even come to see him before he left this world. But after three or four weeks' time the son took the note to the rich man. The boy gave the rich man the note. The rich man read it and asked, "Did I write this?"
The boy said, “I do not know. My father asked me to give it to you before he died." The rich man summoned one of his secretaries and explained, "I promised this boy's father many years ago that I would give him 10,000 rupees if I became rich and great. I have been rich for seven years; please calculate how much interest I have to give him in addition to the 10,000 rupees."
The secretary told him, "An additional 7,000 rupees, which makes it 17,000 altogether."
The rich man immediately issued a check for 17,000 rupees and gave it to the little boy, saying, "Take this directly to your mother.”
This is how a sincere man kept his promise.
56. Which of the following is NOT true according to the passage?
A. The first friend can know others’ future from his or her forehead.
B. The second friend couldn’t believe his friend’s words at first.
C. The first friend wished his friend to help his son after he died.
D. The second didn’t come to see his dying friend because of different life.
57. What do you think of the man who became rich later?
A. He had a bad memory.
B. He is very selfish and unwilling to help others.
C. He is mean with his money.
D. He is a man who keeps his promise.
58. What can be inferred from the passage?
A. The poor friend preserved the note because he knew he would get the money sooner or later.
B. The man became rich 3 or 5 years later after he signed the agreement.
C. The rich man gave the boy 17,000 rupees altogether.
D. The little boy knew something about his father’s story.

You might think body language is universal. After all, we're the same species, right? But basics like what is considered a polite greeting and definitions of "personal space" vary widely from culture to culture. Americans, for instance, are considered rather reserved in the way they greet friends, and they define personal space more broadly than most other cultures. Knowing how another culture's basic body language differs from yours may be of use next time you travel internationally.
Mind how you meet and greet. Americans and Canadians, male and female, tend to greet each other with a nice firm handshake. In Asian countries, the polite form of greeting is to bow, and the lower you bow, the deeper respect you have for the person you are bowing to. In Spain, Portugal, Italy and Eastern Europe, men kiss each other on the cheek.
Be careful about eye contact. In America, intermittent(斷斷續(xù)續(xù)的) eye contact is preferable in a conversation--unless it's someone you care deeply for. In Middle Eastern countries, intense prolonged(持久的) eye contact is the norm, and the person you're speaking with will move very close to you to maintain it. The Japanese, on the other hand, consider it an invasion of privacy, and rarely look another person in the eye.
Americans, in general, smile when they meet or greet someone. Koreans, however, think it's rude for adults to smile in public--to them, smiling in public is a sign of embarrassment.
Don't point. Most Americans think nothing of pointing at an object or another person. Native Americans consider it extremely rude to point with a finger, and instead they point with their chin. It's also rude to point with a finger in China; the polite alternative is to use the whole hand, palm facing up.
Give the right amount of space. In Asian cultures, particularly China, the concept of personal space (generally defined in America as a three-to-four-foot circle for casual and business acquaintances) is nearly nonexistent. Strangers regularly touch bodies when standing in line for, say, movie tickets. People in Scandinavian countries, on the other hand, need more personal space than we do.

A
Your Genes, Your Future
How would you feel if someone gave you an envelope with a description of every one of your genes? Supposing this information could tell you what illnesses you were likely to get, or even what illness you might die of, would you open the envelope?
It's a difficult question to answer. But the fact is that scientists have already begun to discover how certain genes influence us. And in the next decade, they will learn a lot more.
We have known for a long time that many of our physical characteristics are inherited. For example, our eye colour and certain diseases are decided by our genes. As long as you have a good diet, scientists can predict your height by looking at your parents' heights. And we now know that the need to wear glasses has a genetic cause. Our eating habits also appear to be decided by our genes!
With other characteristics, things are not so clear. Certainly, scientists have now shown that some traits are strongly influenced by our genes. Do you prefer getting up early or late? To a great extent, it's your genes that decide, Do you enjoy dangerous sports such as car racing? There is a gene that influences how much excitement we need.
But with most psychological characteristics, scientists are learning that both our genes and our environment affect us. This is true of things such as how violent we are, and how well we get on with other people. So, even though scientists may soon be able to describe our genes in detail, it does not mean they will be able to predict our future with any real success.
Nonetheless, the fact is that scientists will be able to "read" our genes in the near future. This will create new problems. To give a few examples, insurance companies may not want to insure people whose genes predict certain illnesses. Employers may not want to employ people who have a gene for violence. One thing is already clear -- with these new developments, life is going to become even more complicated!
56. Which characteristics is mostly likely to be inherited?
A. Eye colour.      B. Interest.       C. Future.     D. Ability.
57. What kind of problem will these new developments create?
A. You may die of a certain illness described in the envelope.
B. There will be an increased number of violent people.
C. People may take part in dangerous sports such as car racing.
D. Insurance companies may refuse to insure people with a gene for certain disease.
58. Why won’t scientists be able to tell us a lot about our future?
A. Because we’re affected not only by our genes but also by our environment.
B. Because scientists will not able to read our genes in the near future.
C. Because life in the future will be more complicated.
D. Because scientists can’t describe our genes in detail.

C
  Susan Sontag(1933—2004) was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything—to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s,publishing essays in such important magazines as Partisan Review,she appeared as the symbol of American culture life,trying hard to follow every new development in literature,film and art. With great effort and serious judgment,Sontag walked at the latest edges of world culture.
  Seriousness was one of Sontag’s lifelong watchwords(格言),but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In“Notes Camp”, the 1964 essay that first made her name,she explained what was then a little—known set of difficult understandings,through which she could not have been more famous.“Notes on Camp”,she wrote,represents“a victory of‘form’ over‘content’,‘beauty’over‘morals’”.
  By conviction(信念)she was a sensualist(感覺論者),but by nature she was a moralist(倫理學(xué)者),and in the works she published in the 1970s and 1980s,it was the latter side of her that came forward. In“Illness as Metaphor”—published in 1978,after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities(被壓抑的性格),a concept that effectively blamed the victim for the disease. In fact,re-ex-amining old positions was her lifelong habit.
  In America,her story of a 19th century Polish actress who set up a perfect society in California,won the National Book Award in 2000. But it was as a tireless,all-purpose cultural view that she made her lasting fame.
  “Sometimes,”she once said,“I feel that,in the end,all I am really defending…is the idea of seriousness,of true seriousness.”And in the end,she made us take it seriously too.
59.The underlined sentence in paragraph l means Sontag ____________.
A.was a symbol of American cultural life
B.developed world literature,film and art
C.published many essays about world culture
D.kept pace with the newest development of world culture
60.She first won her name through____________.

Have you ever wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves.
Birds, especially seagulls, are very fond of locusts, but birds cannot easily catch locusts because locusts change their colours together with the change of the colour of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown colour as crops have. Some other pests with different colours from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of colouring is to protect themselves. Bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the colour much like the barks of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid spreads over, its enemies cannot find it, and it immediately swims away. Thus, it has existed up to now though it is not powerful at all.
