Our surrounding(周围) is being polluted faster than nature and man’s present efforts can’t prevent it. Time is bringing us more people, an 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 always 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 countryside to cities, eager for the benefit 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.

D．the writer is worried about the future of our society

4.What does the writer really want to say in this passage?

A．With the development of technology, pollution has become a serious problem.

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.

Nowadays, science is developing at a high speed. With the development of science, many countries have improved their economy and raised their people’s living standards. Therefore, science is of great benefit to our daily life.

If we look at the things around us, we’ll find how closely our everyday life is related to science. In one case, at home we can turn on the central heating or air conditioner when we feel cold or hot, and we can watch TV or listen to the tape recorder for entertainment, and we can use a gas stove to cook our meals, and we have computers to help us with our work when we are working in the office, and we also have cars, buses, even planes as traffic tools when we go out. All these things are the results of the scientific development. It goes

without saying that without science our society cannot make rapid progress and our life cannot be comfortable and convenient.

Now that science is so significant in our daily life, we should try to make as many contributions as possible to the development of science. As college students, we must first of all study hard to gain useful scientific knowledge, and then put what we have learnt into practice. We should make the most of science to serve our society.
