答案解析

【答案】D。解析：本题考查的仍是对短文个别段落和中心意思的理解能力。短文第三段集中讲的就是和建房方案之间的关系。A项只说出了建房方案对预算的依赖关系；B项只说出预算对建房方案的依赖关系．而忽略它们相互作用的一面，因此都是片面的。而C项说的是建房方案与预算毫不相干，这与短文交代的事实背道而驰，故予以排除。

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 the 21st century, if presenttrends
continue, we will have used up all the oil that drives our cars, for example. Even if scien-tists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us 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 an American scientist, Professor Carl Sagan.
Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of Venus and so create a new world almost as large as earth itself. The
difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms, which can live in extremely hot or cold atmospheres and
at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus
and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the car-bon dioxide into oxygen and carbon.
When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still
be too hot for men to land on it but the rain will eventually fall and in a few years some-thing like earth will be reproduced on Venus.
In the long run, the most 'difficult problem caused by population groh on earth will probably be the lack of

A． food

B． oil

C． space

D． resources
