Sample1. A world Without OilHave you ever stopped to think how your life would change if
6、the world ran out of oil? Take a look at your day. The roof of your home is probably made waterproof by an oil product, bitumen(沥青).The same product is used for the road surface outside your home. Before you leave to go to work or school just examine your surroundings. Is the room warmer than the co
7、ld air outside? Oil or electricity from oil-fed generators may be keeping you comfortably warm.

9、n. As you head for your bus, train or car, all of them use petroleum products in the form of fuel to move them. What are you wearing today? A polyester shirt or dress, nylon socks and stockings? All these are based on petroleum products.Scientists predict that the worlds known oil resources will run
10、 out early in the next century. But long before then the world will have to decide on its priorities. Can we afford to use so much of our limited petroleum supplies for private motoring? Should airliners compete on similar routes allowing planes to fly long distances with empty passenger seats? What
11、 alternative energy resources can be developed?There is an old English saying, necessity is the mother of invention, which means that when you are faced with a need you will discover some way of fulfilling it. Already scientists are proposing some fascinating solutions. There is one suggestion that
12、the motor traffic and movement of crowds walking on the streets in major cities could generate energy. They say the human and motor traffic in a busy city centre could provide enough energy to light the streets of an entire town or power the heating system for a hospital or school. Some people are d
13、eveloping sophisticated versions of the windmill. Engines can run on alcohol so surplus sugar cane could be used to produce energy. An air ship powered by energy from the sun has been suggested. Such sun ship would have a large enough surface area to carry the enormous number of solar cells necessar

In such circumstances, of course, the tropical parts of the world would have a head start in the race to find new energy sources.2.
