【文章內容簡介】 following way. As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist. Life requires the right amount and kind of atmosphere. This eliminates(除去) all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere。 a larger one would hold too much of it. Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify. Finally, life could evolve(進化) only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away. If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets。 they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out. This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.（1）The existence of life depends on all of the following factors EXCEPT . right amount of atmosphere own solar system heat and light right distance from the sun（2）Which of the following statements is INCORRECT? planet must be as big and heavy as the earth. conditions are essential to the existence of life. stars can provide steady light and heat. distance between a planet and its sun should be right.（3）What kind of planet might NOT support life? of the planets of the stars. similar to our sun. similar to the earth. with proper conditions.（4）At the end of the passage the author suggests that . is impossible for life to exist on planets life could only exist on a few planets could exist on only one planet in a million could exist on a great number of planets【答案】 （1）B（2）C（3）A（4）D 【解析】【分析】本文是一篇說明文，整個宇宙都是由同一種物質構成的，物質在宇宙的每一部分都遵循同樣的規(guī)律。因此，我們有理由猜測，其他恒星，以及它們自己的行星，都是以與我們太陽系相同的方式誕生的。我們對地球上生命的了解表明，只要存在適當的條件，生命就會出現。 （1）考查細節(jié)理解。根據第三段中的“Life requires the right amount and kind of atmosphere”；第四段中“Life also requires a steady supply of heat and light.”以及第五段中“Finally, life could evolve(進化) only if the planet is just the right distance from its sun”可知，生命的進化需要適當數量和種類的大氣、穩(wěn)定的光和熱供應以及行星與太陽的距離恰到好處。文章中沒有提到生命的進化需要太陽系。故選B。 （2）考查細節(jié)理解。根據第四段中的“Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. ” 可知，生命也需要穩(wěn)定的光和熱供應。這就排除了雙星，或突然爆發(fā)的恒星。故選C。 （3）考查推理判斷。根據倒數第二段中的“First, eliminate those stars that are not like our sun. Next eliminate most of their planets。 they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet.”可知，大部分行星都不能維持生命，因為他們要么離太陽太近，要么離太陽太遠，要么與地球大小和重量不一樣，而且適當的條件也并不一定意味著生命確實。故選A。 （4）考查推理判斷。根據最后一段中的“However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.”可知， 然而，即使生命可能只存在于百萬分之一的行星上，但仍有數十億的行星可能存在生命。可知，生命可能在許多星球存在。故選D。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準確掌握細節(jié)信息，并根據上下文進行邏輯推理，從而選出正確答案。5．閱讀理解 Ana, her husband Mario, and their fouryear old son Antonio just moved to North Carolina. They need a temporary place to call home until they get settled into their new surroundings. So, Ana figured that she had better start looking for an apartment for them to stay in. First, Ana picked up an Apartment Book at her local newspaper stand. The Apartment Book contained listings of all the major apartment plexes in her area. Ana started by looking at the prices in the advertisements for apartments in the Apartment Book. Then, she read about the amenities that each apartment plex offered. For example, some apartments had a clubhouse, a gym (also called a fitness center), and a pool. After considering prices, amenities, and locations, Ana found a few apartment plexes that she liked. Ana called the apartment plexes. She set up appointments with the apartment managers to see the apartments she found interesting. Ana made five phone calls, total. I39。ll see you then, she said to the fifth apartment manager, and hung up the phone. When Mario got home (to the hotel in which they were staying) from work, Ana showed him the list of apartments. These look good, he said. Mommy, let me see, said Antonio, whom Mario had just brought home from childcare. Ana showed Antonio the pictures of the apartments. The next day, while Mario was at work and Antonio was at childcare, Ana visited the apartment plexes. After visiting all five, she found that she liked the fifth one the best. It was near a good school system for her son, and it was near her and her husband39。s workplace. She went home and discussed it with her husband, and they decided that they wanted to rent the apartment. The next day, they called the manager of the apartment plex and told him that they would like the apartment. The manager asked them to sign a rental contract and pay a security deposit so that if any damage was done to the apartment while they were in it, the security deposit would pay for it. They signed the rental contract and paid the security deposit. Finally, they had a place to stay.（1）Which of the following is not an amenity? . cente
