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 try to find out alternative sources of power. According to Professor Ma 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 the only alternative.

However, many people do not approve of using nuclear power because it is very dangerous. What would happen if there were 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 economically as possible.

Exercise 1:

The idea of a driverless car is not new. Now there are already cars on the road that can park themselves. But a truly self-driving car, one that can drive itself, is being tested by scientists and engineers.

Self-driving cars have already tested on public roads. These cars not only record images of the road, but their computerised maps view road signs, find alternative routes and see traffic lights even before they are seen by a person. By using radars and cameras, the cars can analyse information about their surroundings faster than a human can.

In some of the tests, the car learn the details of a road by driving on it several times, and when it is time to drive itself, it can identify when there are pedestrians crossing and then stops to let them pass by. Self-driving cars could make transport safer for all of us by eliminating the cause of most of today's accidents.

Although self-driving cars may seem far off, some people believe that there will be driverless cars in showrooms in about 10 years.
