Test Nature and Environment

Variant 1

1. Match the questions (A-E) with the paragraphs (1-5).

A What causes global warming?

B What will happen if global warming continues?

C What do experts think about global warming?

D What can I do about global warming?

E Is anybody doing anything about global warming?

Global warming

1 _____ Nobody really knows for sure how fast the planet is heating up. Experts do know, however, that if we don’t do anything about it, the problem will continue to get worse.

2 _____ Scientists blame fossil fuels for global warming. You see, when you burn gas or oil, they produce greenhouse gases. Then, when these greenhouse gases are trapped in the atmosphere, they prevent heat escaping into space and make the planet warmer. Cutting down trees adds to the problem.

3 _____ Slowing down global warming is a very difficult task and it seems that people can’t agree on what to do. Some people think that if governments make laws about it, that will help. Others believe that it should be up to each person or company to decide what to do.

4 _____ Again, the answer is, “Nobody really knows for sure”. However, people who study the Earth’s climate can make guesses. They believe that when the Earth keeps getting warmer, the sea level might rise, animals may become extinct, and there may be more storms and floods.

5 _____ It’s simple! If you use less energy, you’ll help slow down global warming. If you want to use less energy, turn off lights when you leave a room; use air conditioners wisely; take shorter showers; turn off a TV set when you go out.

2. Mark if the sentences are true or false.

_____ 1. Scientists don’t worry about global warming.

_____ 2. Gas and oil are fossil fuels.

_____ 3. The destruction of forests is one of the cases which cause global warming.

_____ 4. It isn’t hard to stop global warming.

_____ 5. Everybody is sure that only governments can stop global warming.

_____ 6. Global warming may have negative results.

_____ 7. People must use more energy to stop global warming.

_____ 8. We must use water economically.
