15、have made it possible to detect planets in our own Milky Way and in other galaxies. This is a major achievement because, in relative terms, planets are very small and do not give out light. Finding planets is proving hard enough, but finding life on them will prove infinitely more difficult. The fir
16、st question to answer is whether a planet can actually support life. In our own solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than four billion years for plant and animal life to evo
17、lve(进化) Whether a planet can support life depends on the size and brightness of its star, that is its “sun”. Imagine a star up to twenty times larger, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable(有能力的) of supporting life. On the contrary, if t
18、he star were small, the lifesupporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we find such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. The develo
19、pment of such a telescope will be one of the great astronomical projects of the twentyfirst 第 5 页 共 8 页 century.It is impossible to look for life on another planet using earthbased telescopes. Our own warm atmosphere and the heat generated (产生) by the telescope would make it impossible to detect obj
20、ects as small as planets. Even a telescope in orbit round the earth, like the very successful Hubble telescope, would not be suitable because of the dust particles in our solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space, because the dust be
21、comes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet, we would have to find a way of blocking out the light from its star, so that we would be able to “see” the planet properly and analyze its atmosphere. In the first instance, we would be lo
22、oking for plant life, rather than “little green men”. The life forms most likely to develop on a planet would be bacteria. It is bacteria that have generated the oxygen we breathe on earth. For most of the earths history they have been the only form of life on our planet. As Earthdwellers, we always
23、 cherish the hope that we will be visited by little green men and that we will be able to communicate with them. But this hope only exists in science fiction. If we were able to discover lowly forms of life like bacteria on another planet, it would completely change our view of ourselves. As Daniel
24、Goldin of NASA observed, “Finding life elsewhere would change everything. No human efforts or thought would be unchanged by it.”【语篇解读】 本文为一篇天文科学报道，属说明文。文章讲述了行星与恒星的关系，行星上存在生命需具备的条件及如何才能发现其他星系的行星。1Why are planets in other solar systems much more difficult to detect than stars?ABecause of the dust part
25、icles in our own solar system.BBecause of the limitations of earthbased telescope.CBecause even the Hubble is not powerful enough to see beyond the Milky Way.DBecause planets are small and dark, and stars are large and radiant.答案 D 细节推断题。难度中等。根据文章第一段第一、二句 “天文学方面最新发展使得我们能够在银河系和其他星系发现行星。 这是一个重要的成就。因为相
26、对来说，行星很小，而且也不发光。 ”可知，D 项表述正确。故答案选 D。2The word “infinitely” (Paragraph 1) can best be replaced by_.Aoccasionally BprobablyCextremely Dslightly答案 C 词义猜测题。难度中等。画线词所在句的句意为 ：寻找行星相当困难，但是要在行星上发现生命会“无比” 艰难 。所以， infinitely 应意为“极多地，极其地”。故答案选 C。3What do we know about the kind of planet, other than our own, tha
27、t might be able to support life?AIt will orbit closely round its star.BIt will be at least four billion years old.第 6 页 共 8 页 CIts distance from its star will be such that it has a moderate temperature.DIt will have an atmosphere capable of supporting bacteria.答案 D 细节理解题。难度中等。根据文章第一段后两句及最后一段第五、六、七句可
28、知，要想有生命存在，首先行星要与恒星距离适当。一旦我们找到这样一颗行星，我们就要想办法挡住它的恒星射过来的光线，这样我们就能彻底“ 看见”这颗行星，并分析它的大气层。首先我们要寻找植物，而不是那种 “小绿人”。行星上最容易生存下来的是细菌。正是 细菌生产出我们在地球上呼吸的氧气。故答案选 D。4A telescope capable of finding life on other planets would have to be_.Afar enough from the center of our solar system not to be affected by dustBinfini
29、tely more powerful than even the very successful HubbleCorbiting in a different solar system a long way away from our ownDon the planet Jupiter, on the edge of our solar system答案 A 细节理解题。难度中等。根据文章最后一段前四句，使用放置在地球上的望 远镜是无法观察到其他行星的生命的。地球周围温暖的大气 层和望远镜散出的热量使得我们根本不可能找到比行星更小的物体。即使是一台放置在围绕 地球的轨道上的望远镜如，非常成功的
30、哈勃望远镜也因为太阳系中的尘埃微粒而无法胜任。望远镜要放置在木星那样遥远的行星上才有可能在外层空间搜寻生命。因 为我 们越是接近太阳系的边缘， 尘埃就越稀薄。可知 A 项表述正确。故答案 选 A。5When the writer says “The development of such a telescope will be one of the great astronomical projects of the twentyfirst century.” he means_.Ascientists of the 21st century must work on such a proje
31、ctBthere is still a long way to go to develop such a telescopeCwe must develop such a telescope to observe other planetsDsuch a telescope will be developed in the 21st century答案 B 细节推理题。难度中等。根据第二段倒数第二句及最后一段的第三句可知，现在，没有一台现存的望远镜可以 发现生命的存在。即使是一台放置在围绕地球的轨道上的望远镜如，非常成功的哈勃望 远镜也因为太阳系中的 尘埃微粒而无法胜任。因此，要开发出这样的望
32、远镜还有很长的路要走。故答案 选 B。6It can be inferred from the passage that_.Athe Hubble telescope is suitable for any space explorationBwe humans will be visited by little green menCfinding life on another planet will be shocking newsDno achievement has been made in astronomy第 7 页 共 8 页 答案 C 推理判断题。难度中等。根据文章最后一段第三句可知，A 项错误；根据最后一段倒数第三、四句可知，B 项错误；根据文章第二段说的，行星是否有生命与恒星的关系，及最后一段第三句所提到的非常成功的哈勃望远镜，可知 D 项错误。故答案选 C。第 8 页 共 8 页
