　　.閱讀理解

　　(2024·遼寧丹東五校聯(lián)考)If the earth’s population is in growth at this rate，there will not be enough resources.By the middle of the 21st 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 the 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 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 the 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 (海藻有機(jī)體) 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 algae will break down the carbon 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 man to land on but the rain will eventually fall and in a few years something like the earth will be reproduced on Venus.

　　語(yǔ)篇解讀　本文是一篇說(shuō)明文。地球上的資源越來(lái)越少，人類(lèi)的生存即將面臨挑戰(zhàn)。如何拯救地球上的人類(lèi)？一些科學(xué)家提出了移民金星的建議，同時(shí)建議在地球資源耗盡之前在金星上培植一種海藻有機(jī)體，讓金星產(chǎn)生與地球一樣的生存環(huán)境。1．In the long run，the most difficult problem caused by population growth on the earth will probably be the lack of ________.

　　A．oilB．food

　　C．resources D．space

　　D　[細(xì)節(jié)理解題。根據(jù)第一段第三句Even if scientists develop new ways of feeding the human race...look for open space somewhere else.可知，即使科學(xué)家開(kāi)發(fā)出了供養(yǎng)人類(lèi)的新方式，但是地球上擁擠的狀況也使得人們?nèi)ふ腋_(kāi)闊的空間。由此可知，人口膨脹最大的問(wèn)題是空間的問(wèn)題。故選D項(xiàng)。]

　　2．Carl Sagan believes that Venus might be a living place because ________.

　　A．the days on Venus are long enough

　　B．it might be possible to change its atmosphere

　　C．there is a good supply of water on Venus

　　D．its atmosphere is the same as the earth’s

　　B　[細(xì)節(jié)理解題。根據(jù)第二段第一句．..it will be possible to change the atmosphere of Venus and so create a new world almost as large as the earth itself.可知，金星有可能改變它的大氣繼而成為適宜人類(lèi)生存的地方。故選B項(xiàng)。]

　　3．Algae are plants that can ________.

　　A．live in very hot temperature

　　B．live in very cold temperature

　　C．produce oxygen

　　D．a(chǎn)ll of the above

　　D　[細(xì)節(jié)理解題。根據(jù)第三段第一句可知，海藻有機(jī)體可以在極熱和極冷的溫度下生存，同時(shí)還能產(chǎn)生氧氣。故選D項(xiàng)。]

　　4．Man can land on Venus only when ________.

　　A．it rains there

　　B．there is oxygen

　　C．the atmosphere becomes cooler

　　D．the algae have done their work

　　A　[推理判斷題。在文章最后一段中提到，在人類(lèi)踏足金星之前需要氧氣去制造雨水，然后又提到雨水最后會(huì)降落到金星上使得氣溫下降，這樣人類(lèi)就可以居住了。由此可以推測(cè)A項(xiàng)正確。]

　　C．produce oxygen

　　D．a(chǎn)ll of the above

　　D　[細(xì)節(jié)理解題。根據(jù)第三段第一句可知，海藻有機(jī)體可以在極熱和極冷的溫度下生存，同時(shí)還能產(chǎn)生氧氣。故選D項(xiàng)。]

　　4．Man can land on Venus only when ________.

　　A．it rains there

　　B．there is oxygen

　　C．the atmosphere becomes cooler

　　D．the algae have done their work

　　A　[推理判斷題。在文章最后一段中提到，在人類(lèi)踏足金星之前需要氧氣去制造雨水，然后又提到雨水最后會(huì)降落到金星上使得氣溫下降，這樣人類(lèi)就可以居住了。由此可以推測(cè)A項(xiàng)正確。]
