Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content. It is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.What is the text mainly about?

Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was seventy-five, he gave £ 12，000 to the village school to buy land and equipment (设备) for a children’s play ground.
As a result of his kindness, many people came to visit him. Among them was a newspaperman, During their talk, Johnson remarked that he was seventy-five and expected to live to be a hundred. The newspaperman asked him how he managed to be healthy at seventy-five, Johnson had a sense of humor (幽默). He liked whisky (威士忌酒) and drank some each day. “I have an injection (注射) in my neck each evening.” He told the newspaperman, thinking of evening glass of whisky.
The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was seventy-five and has a daily injection in his neck.

Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own.
Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature.
Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.Which of the following statements is NOT true?
| A．People who like country things prefer to live outside the city. |
| B．People who work in London prefer to live in the country. |
| C．Because of certain disadvantages of living outside London, some people who work in London prefer to live inside London. |
| D．Because of certain advantages of living outside London, many people who work in London prefer to live outside London. |

Tom arrived at the bus station quite early for the London bus. The bus for London would not leave until five to twelve. He saw a lot of people waiting in the station.

His first fight was for the equal rights of black people in South Africa. Then, as the first black president he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.
On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.
Mandela was born in a small village in South Africa in 1918. He was adopted (收养) by the chief of his tribe (部族) and could have been a chief himself and lived a happy country life.
But he refused to be a chief when his people lived under racial discrimination ( 种族歧视). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law (种族隔离法), colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.
For his opposition (反对) to the system Mandela was arrested (被捕) and spent 27 years in prison. He was freed in 1990 and become the president of the country after the first elections were held in which everyone could vote.
Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer (拳击手) and fought in the ring when he was young.
“ Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat (撤退),” he wrote in his autobiography.
As a skilful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.Nelson Mandela succeeded in doing the following except _____.
| A．winning the equal rights for the black people in South Africa |
| B．uniting South Africa |
| C．organizing a government in South Africa |
| D．controlling the spread of AIDS |
If Nelson Mandela hadn’t fought against racial discrimination, he _____.
| A．could easily have been the president of South Africa |
| B．could still have lived a happy life |
| C．could have been in a difficult situation |
| D．would have been an excellent boxer |
It can be inferred that Nelson Mandela _____.
| A．continues to help the black people with the political struggle |
| B．is taking a position in a music group |
| C．is taking on the world’s greatest fight against AIDS |
| D．is preparing for the next election of president |
