When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were B. whether they would grow back
C. how long it would take to re-grow D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins. B. Proteins similar to n-AG.
C. Stem cells and proteins. D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in B. shows where researchers got their new ideas
C. states the author’s opinion D. describes the result of researchers’ studies

When I was about 10 one day, I was walking down the street with my mother. She stopped to speak to Mr. Lee. I knew I could see Mr. Lee anytime around the neighborhood, so I just stood there. After we passed him, my mother stopped and said something unforgettable, “You let that be the last time you ever walk by somebody you know without opening your mouth to speak, because even a dog can wag its tail when it passes you on the street.” That sentence sounds simple but it made me become who I am.
At work, I used to say hello to the president of the company and ask him how our business was doing. But I also spoke to the people in the café and people who cleaned the buildings, and asked them how their children were doing, for every single person deserves to be accepted, no matter how humble(低微的) they are. I remember that after a few years of passing by the president, I had the courage to ask him for a chat. We had a great talk. At some point, when I asked him how far he thought I could go in his company, he said that if I wanted to, I could get all the way to his seat.
I’ve become vice-president, but that hasn’t changed how I treat people. I speak to people wherever I am. Speaking to people creates a pathway into their world, and it lets them come into mine, too.
The day you speak to someone who has his head down and then see him lift it up and smile, you will realize how powerful it is just to open your mouth and say hello.

When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes－the TV cameramen－have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.
Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN－have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.
These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.
TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.
By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.
69. The freelance cameramen .
A. have better skills than other cameramen
B. are tied to many TV news agencies
C. have to take tremendous(巨大的) risks in the course of work
D. need to contract out risks of work for TV companies
70. It is implied in the passage that .
A. TV cameramen have to witness disasters and killing whether they like them or not
B. TV cameramen are a special group of people who enjoy horrifying pictures
C. TV cameramen should be given greater choice of work
D. the development of TV resulted in the growing demand for TV cameramen’s work
71. According to this passage, some major broadcasters and TV news agencies .
A. have employed enough cameramen
B. are not willing to employ many cameramen
C. are very mean to freelancers
D. are responsible for the freelancer if he is injured
72. The author of this passage shows his the freelance cameramen.
A. respect for B. sympathy to C. anger to D. admiration to

When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate (照亮) me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say: “Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changed into social creatures and the stories and poems stopped.
When I lived for a time in London, I had a friend. He was in despair and I was in despair. But our friendship was based in the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.
For almost four years I have had a remarkable friend whose imagination ill
uminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think: “Yes, I must tell…” we have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist, who will only fill up the healing (愈合的) silence necessary to those darkest moments in which I would rather be my own best friend.

A. become serious about her study B. go to her friend’s house regularly

65. What is the best title for the passage?

When it comes to romance（浪漫）, women prefer someone who is humorous while men choose those who catch their eye, according to an international survey.
The survey, done in 16 countries by Canadian romance publisher Harlequin Enterprises, asked men and women on six continents about personality they liked or disliked and how they went about trying to meet Mr. or Ms Right.
The survey showed differences between countries in the way people tried to impress the opposite sex.
Australians and British men frequently admitted drinking too much, while about half of German and Italian men said they had lied about their finances. Spaniards(people in Spain) were the most likely to use sex to catch someone’s attention.
Eighty percent of Brazilian and Mexican men said they had lied about their marriage or romance as did 70 percent of German women, the survey said.
When it came to meeting that special someone, a majority of respondents(被告) preferred to rely on friends for introductions. The Internet was not a popular hunting ground except in Portugal, where about half the surveyed men and women would like to find people online.
There was a gap between the two sexes in Spain and France. Thirty percent of Spanish men, but no Spanish women, looked for love online. In France, 40 percent of men but only 10 percent of women attended parties, bars and clubs to meet someone, but they did have one thing in common: both sexes regarded looks as more important than their counterparts（相对应的人） in other countries.
When it came to that first meeting, a majority of men surveyed said beauty was more important than brains, while women put a sense of humor at the top of their list.
Physical attraction was the most important for men in France, Brazil, Greece, Japan and Britain. And while 40 percent of Portuguese men regarded intelligence over looks in a first meeting, no Australian men did so.
In the United States and Canada, humor was considered the most important personality by men and women, getting 63 and 73 percent of the vote respectively.
55. Appearance is the most important for men in the following countries except in ___________.
A. Britain B. Japan C. France D. Spain
56. According to the passage, which of the following is TRUE?
A. Portuguese enjoy looking for love online best.
B. Humor is considered the most important personality by both Americans and Australians.
C. Brazilian and Mexican men like to lie about their finances.
D. Few people preferred to rely on friends for introductions.
57. Which is NOT mentioned as the standard of looking for love in the passage?
A. Humor. B. Generosity. C. Beauty. D. Intelligence.
58. The purpose of the writer is to tell us _________________ when choosing the opposite sex.

C. not all men prefer beauty to brains
