三、阅读理解：(共30分)
If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else.But none of the other planets in our solar system are capable of supporting life at present.One possible solution to the problem,however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself.The
difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done,the algae will be placed in small rockets.Spaceship will then fly to Venus and fire the rockets into the atmosphere.In a fairly short time,the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work,the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain.The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.
1.Inte long run,the most insoluble problem caused by population growth on earth will probably be the lack of______.
A.food
B.oil
C.space
D.resources

A.it might be possible to change its atmosphere

C.there is a good supply of water on Venus

3.On Venus there is a lot of________.
A.water
B.carbon dioxide
C.carbon monoxide
D.oxygen
4.Algae are plants that can____.
A.live in very hot temperatures
B.live in very cold temperatures
C.manufacture oxygen
D.all of the above
5.Man can land on Venus only when_______.
A.the algae have done their work
B.the atmosphere becomes cooler
C.thereis oxygen
D.it rains there
