The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.

LONDON (Reuters) ---Organic fruit, carried right to the doorstep. That is what Gabriel Gold prefers , and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.
“Organic produce is always better,” Mr. Gold said. “The food is free of pesticides(杀虫剂), and you are generally supporting family farms instead of large farms. And more often than not it is locally grown and seasonal, so it is more tasty.” Mr. Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are depending on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic produce? Market research shows that Mr. Gold and others who buy organic food can generally give clear reasons for their preferences---but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic produce. And about three quarters of organic food in Britain is not local but imported to meet the growing need. “The demand for organic food is increasing by about one third every year, so it is a very fast-growing market.” Said Sue Flock, a specialist in this line of business.
1. More and more people in Britain are buying organic food because____________.
A. they are getting richerB. they can get the food anywhere
C. they consider the food free of pollution D. they like home-grown fruit
2. Which statement is TRUE according to the passage?
A. Those who buy organic food have a complete knowledge of organic food.
B. Some of the organic food is produced outside Britain.
C. Organic produce is not seasonal and tastes more tasty.
D. Organic products are those which are free of pesticides.
3. The underlined words “organic trend” means____________.
A. higher prices of organic food B. better quality of organic food
C. rising market for organic food D. growing interest in organic food
4. The news story is mainly about____________.
A. that more and more people prefer organic food in Britain
B. the production of organic food in Britain
C. the complete knowledge of organic food in Britain
D. good qualities of organic food in Britain

第三部分阅读理解（共20小题；每小题2分，满分40分）
The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
1. According to this passage, we can know____________.
A. perhaps most of human illness is caused by what we eat
B. perhaps most kinds of cancer are related to what people eat
C. cancer was discovered in 1945 D. science has made food unfit to eat
2. Things that are used to keep colours in meats are____________.
A. harmful B. useless C. helpless D. dangerous
3. All the additives____________.
A. are bright and colourless
B. are not bright and colourful
C. have indirect effects on our health
D. have direct effects on our health
4. Which of the following is not true?
A. Some wrappings of food are harmful.
B. Farmers try to make more money on the market by fattening their animals.
C. “The practice continues” means “things are still going on like that”.
D. We needn’t take care of what we eat.

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure — and so soon — that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet”when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet”quickly goes away. When other ants detect the“dead”chemical without the“not dead yet”chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the“Wait—I'm not dead yet”chemical, other ants left the treated ant alone. Choe believes this behavior shows that the“not dead yet”chemical overrides the“dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest.[
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

A boy was born to a couple after eleven years of marriage. They were a loving couple and loved the boy very much. When the boy was around two years old, one morning the husband saw a medicine bottle open. He was late for work so he asked the wife to cap the bottle and keep it in the cupboard. The mother, preoccupied in the kitchen, totally forgot the matter.
The boy saw the bottle and playfully went to the bottle and, fascinated with its color, drank it all. It happened to be a poisonous medicine meant for adults in small dosages. When the child collapsed, the mother hurried him to the hospital, where he died. The mother was stunned. She was terrified how to face her husband.
When the distraught father came to the hospital and saw the dead child, he looked at his wife and uttered just four words. The husband just said ‘I am with you, Darling’. The husband's totally unexpected reaction is proactive behavior. The child is dead. He can never be brought back to life. There is no point in finding fault with the mother. Besides, if only he have taken time to keep the bottle away, this will not have happened. No point in attaching blame. She had also lost her only child. What she needed at that moment was consolation and sympathy from the husband. That is what he gave her.
If everyone can look at life with this kind of viewpoint, there would be much fewer problems in the world. Take off all your envies, jealousies, unforgiveness, selfishness, and fears and you will find things are actually not as difficult as you think. Sometimes we spend time asking who is responsible or whom to blame, whether in a relationship, in a job or with the people we know. By this way we miss out some warmth in human relationship.
