II. Read the passage, and choose the correct answer A, B, C or D for each
question.
Many people still believe that natural resources will never be used up. Actually, the
world's energy resources are limited. Nobody knows exactly how much fuel is left.
However, we also should use them economically and try to find out alternative sources
of power. According to Professor Marvin Burnham of the New England Institute of
Technology, we have to start saving coal, oil and gas before it is too late; and solar
power is the only alternative.
However, many people do not approve of using nuclear power because it's very
dangerous. What would happen if there was a serious nuclear accident? Radioactivity
causes cancer and may badly affect the future generations. The most effective thing is
that we should use natural resources as economical as possible.
