I. Fill each of the numbered blanks in the following passage with a suitable word.

About two hundred years ago, man lived in (1) greater harmony with his environment because/ since/ as (2) industry was not much developed. Today the situation is quite different (3). People all over the world are worried about what is happening to the environment (4), because of modern industry and the need for more and more energy. Newspapers and magazines write (5) about water pollution, air pollution, and land pollution.

Why is there so much discussion about pollution (6)? After all, people have been polluting the world around (7) them for thousands and thousands of years. But in the past (8), there were not many (9) people and there was lots of room in the world so people could move to another place when (10) their settlements became dirty.

Now, however, many parts of the world are crowded (11). People live in big cities and much of our waste, especially waste (12) from factories, electric power stations, the chemical industry and heavy industry is (13) very dangerous. Fish die in the lakes, rivers, and seas; forest trees die too. Much of this dangerous (14) waste goes into the air and is carried by the wind (15) for great distances.

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. The most effective thing is that we should use natural resources as economical as possible

Read the passage below and an answer the question :

We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .

1 Can electricity be produced from any sources of energy?

2 What would happen if we didn't waste so much energy?

3 Why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?
