　　Recently studies have shown that the earth is getting warmer. The scientists who carried out the studies say a large amount of CO₂ in the atmosphere is the reason for the warming. CO₂ is the gas which human and animals give off when They breathe. It is also produced when coal, oil and other things are burnt. Scientists have warned that this kind of burning is adding too much CO₂ to the atmosphere. They believe the gas acts like a green house--the grass-topped building used to grow plants in cold weather. They say the gas is like the grass roof of a green house, which lets in sunlight, but prevents heat from running away. As a result, they say the earth becomes warmer.

　　One of these scientists, Dr. Hansen, says the weather will become so hot that some rivers will dry up. On the other hand, satellite pictures show us there is less ice in the Antarctic during the summer time than in earlier years. The heat would turn all the ice at both ends of the earth into water, making the oceans rise five to seven meters higher than they are now.

[　　]

A. there are too many human and animals on the earth

(2)Farmers in cold weather build some green houses to ________.

[　　]

A. keep warm in winter

B. get some more sunlight

C. get some heat to plant some vegetables

D. prevent some vegetables from shining

[　　]

A. it can give heat to the earth

B. it can prevent heat from running away

C. it can absorb heat form the sun

D. it cam pollute the atmosphere

(4)According to the view of Dr. Hansen, some day in the future ________.

[　　]

A. all rivers on the earth will dry up

B. the water level on land will rise five to seven meters higher

C. all ice in the Antarctic will turn into water

D. all ice on the earth will turn into water

(5)What do you think the best way to prevent the earth from getting warmer?

[　　]

A. Many animals should be get rid of.

B. Many kinds of materials should be used again.

C. The growing increase of population should be controlled.

D. Something should be done to prevent air pollution.
