问题     The air is polluted. The earth is poisoned. Water is unsafe to drink and garbage is burying the civilization that produced it.
    Our environment is being polluted faster than nature man’s efforts can prevent it. Time is bringing us more people, and more people will bring us more industry. More people and more industry will bring us more motor-cars, larger cities, and the growing use of man made materials. This is happening not only in the advanced societies but among the developing nations as they become industrialized.
    Now many scientists are worrying about the possibility of world pollution. Some experts declare that the balance of nature is being so upset that the very survival of human beings is in danger.
    What can solve this problem? The fact is that pollution is caused by man—by his greed and his modern way of life. We make "increasing industrialization" our chief aim. For its sake we are willing to sacrifice everything: clean air, pure water, good food, our health and the future of our children. There is constant flow of people from the countryside into cities, eager for the benefits of modern society. But as our technological achievements have grown in the last twenty years, so has pollution become a serious problem.
    Isn’t it time that we stopped to ask where we are going and why? It reminds us 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 are going." The sad fact is that this becomes a true story when applied to our modern society.

选项 A、the use of man-made materials has had harmful effects on the modern civilization
B、pollution has become a more and more serious problem which is threatening the survival of human beings
C、our technological achievements have grown rapidly in the last twenty years
