题目列表(包括答案和解析)
In today's world, almost everyone knows that air pollution（污染）and water pollution are harmful to people's health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.
People who work and live under noisy conditions usually become deaf（聋）. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave（织）cloth become deaf. Quite a few people living near airports also become deaf.

A new study warns that about thirty percent of the world people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three hundred and thirty-five million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
PAI researchers Robert Engel says by the year 2025,about three thousand million people lack water. At least 18 more countries are, expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.
Mr. Engel says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will increase.
The report says lack of water in the future may result in several problems. It may increase health problem. Lack of water often means drinking water is not safe. Mr. Engel says there are problems all over the world be cause of diseases such as cholera（霍乱）that is carried in water.
Lack of water also results in more international conflict（冲突）. Countries may have to fight for water in the future. Some countries now get sixty percent of their water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability to improve their economics. This is because new in dustries often need large amounts of water when they are beginning.
The Population Action International study gives several solutions（解决方法）to the problem, One way, it says. is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third is to use less water for agriculture.
The report also says long-term solution to the water problem must in clued controls on population growth.

Our surroundings are being polluted faster than nature and man’s present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and solve this problem? The fact is that pollution is caused by man — by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going — and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.
Man cannot prevent the world from being polluted mainly because ______.
A. the population of the world is decreasing fast
B. people use too many man-made materials
C. we have more and more industry
D. we are producing more cars, trucks and buses
People crowd into the cities because ______.
A. they want very much to find well-paid jobs
B. they are anxious to enjoy the achievements of our society
C. they have become tired of their homeland
D. they have a strong wish to become industrial workers

A. Industry. B. Health.
C. Clean air. D. The future of the children.
The story about the airline pilot tells us that ______.
A. man knows where the society is going
B. people do not welcome the rapid development of modern society
C. man can do little about the problem of pollution

B. Lower the speed of development to stop pollution.
C. It’s time we did something to reduce pollution.
D. As industry is growing fast, pollution is the natural result.
China’s second manned（人造的） space flight will be done by two astronauts（宇航员） over five days in 2005. “Shenzhou-VI will be sent into space sometime in 2005,” said Zuo Saichun, a spokesperson of the China Aerospace Science and Technology (CAST). “The spacecraf
t（宇宙飞船） will make new breakthroughs（突破性进展） in China’s manned space technology.”
Unlike Shenzhou-V, a little more than a year ago (in October, 2003), the next flight will see two astronauts fly in space for five days. Their capsule (太空舱) is designed to be capable（能够）of orbiting（绕轨道运行） for a whole week, the spokesperson said. “For the first time, astronauts will enter and live in the orbital module（舱） of the spacecraft to do scientific experiments,” said a statement from CAST. CAST did not say what those experiments will be.
In Shenzhou-VI, scientists have changed the spacecraft’s configuration (构形) to reduce its weight, and tried to improve the performance of on-board equipment. They have also worked to make sure of the energy supply of the spacecraft and further improve its safety. So far, scientists have worked out ways to solve problems on environmental control and life support. Shenzhou-VI will be sent into orbit atop（在……顶上） a Long March 2F rocket.
Meanwhile, a model of the Chang’e-1 satellite is expected to be sent to orbit the moon in two years. The satellite, part of the three-stage programme, would be followed by the landing of an unmanned vehicle on the moon in the second stage by 2010 and collecting samples（样品） of lunar soil by 2020 in the final stage, according to Sun Laiyan, director of the China National Space Administration.
