In today’s world, almost everyone knows that air pollution 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. 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. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people’s life difficult and unpleasant, or even make people ill or even drive them mad.
It is said that a continuous noise of over 85 decibels（分贝） can cause deafness. Now the governments in many countries have made laws to control noise and make it less than 85 decibels.

The word science is heard so often in modern times that almost everybody has an idea of its meaning. However, its definition is difficult for many people. The meaning of the term is confusing, but everyone should understand its meaning and objectives (目标). Just to make the explanation as simple as possible, suppose science is defined as classified knowledge or facts.
Even in the true science, distinguishing fact from fiction is not always easy. For this reason great care should be taken to distinguish between beliefs and truths. There is no danger as long as a clear difference is made between temporary and proved explanations. For example, hypotheses(假设) and theories are attempts to explain natural phenomena. From these positions the scientist continues to experiment and observe until they are proved or discredited. The exact status of any explanation should be clearly labeled to avoid confusion.
The objectives of science are primarily the discovery and later the understanding of the unknown. Man cannot be satisfied with recognizing that secrets exist in nature of that questions are unanswerable; he must solve them. Toward that end, specialists in the field of biology and related fields of interest are directing much of their time and energy.
Actually, two basic approaches lead to the discovery of new information. One, aimed at satisfying curiosity, is referred to as pure science. Sometimes practical-minded people miss the point of pure science in thinking only of its immediate application for economic rewards. However, one should remember that the construction of the microscope had to come before the discovery of the cell. The host of scientists devoting their lives to pure science are not apologetic about ignoring the practical side of their discoveries; they know from experience that most knowledge is eventually applied.
The other is aimed at using knowledge for specific purposes--for instance, improving health, raising standards of living, or creating new consumer products. In this case, knowledge is put to economic use. Such an approach is referred to as applied science.

We don’t know how different our life will be in the future. We can only try to imagine it. 
At first we think about human relationship. In the year 2050, we will use computers almost every day. We will make new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today-we will feel a little lonely.
Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.
Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will use solar-powered cars, which will be much more environmentally friendly.
We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.
Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen. Why will people probably feel a little lonely in 2050?
| A．Because the number of people will become much smaller. |
| B．Because there will be less face-to-face communication. |
| C．Because people won’t like making friends with each other. |
| D．Because people won’t communicate with each other much often. |
The third paragraph mainly tells us ________.
| A．computers will do all the things for human beings |
| B．how people will use computers to communicate with each other |
| C．machines like computers and robots will help people a lot |
| D．how people will use robots to do the housework |
According to the passage, which of the following will happen in 2050?
| A．The relationship between people will be more important than that of today. |
| B．The way of spending holidays will be the same as that of today. |
| C．It won’t be difficult for people to travel to other planets. |
| D．Our environment will be much more polluted with a growing number of cars. |
What does the passage mainly talk about?
| A．How people will communicate in the year 2050. |
| B．What our life will be like in the year 2050. |
| C．How people will travel and spend their holidays in the year 2050. |
| D．What high technology will appear in the year 2050. |
I was in a strange city I didn’t know at all, and what’s more, I could not speak a word of the language. On my second day I got on the first bus that passed, rode on it for several stops, then got off and walked on. The first two hours passed pleasantly enough, then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way. The trouble was that the only word I knew of the language was the name of the street in which I lived, and even that I pronounced badly. I stopped to ask a newspaper-seller. He handed me a paper. I shook my head and repeated the name of the street and he put the paper into my hands. I had to give him some money and went on my way. The next person I asked was a policeman. He listened to me carefully, nodded and gently took me by the arm. There was a strange look in his eyes as he pointed left and right and left again. I nodded politely and began walking in the direction he pointed.About an hour passed and I noticed that the houses were getting fewer and fewer and green fields were appearing on either side of me. I had come all the way into the countryside. The only thing left for me to do was find the nearest railway station. From the story we know that the policeman______.
| A．was kind but didn’t understand the writer |
| B．told the writer where to take a train |
| C．knew what the writer really meant |
| D．was cold-hearted and didn’t help the writer |
What can we learn from the last paragraph?
| A．The writer got close to the hotel where he stayed. |
| B．The writer got to the hotel with the policeman’s help. |
| C．The writer found he was much farther away from the hotel. |
| D．The writer found the hotel in the direction the policeman pointed. |
In your opinion, what was the writer’s real trouble?
| A．He didn’t know the city at all. |
| B．He couldn’t speak the language. |
| C．He went too far in the wrong bus. |
| D．He followed the policeman’s direction. |
