 V: Read the passage, choose True or False.
 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
 conserving coal, oil and gas before it is too late; and nuclear 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.

 possible.
