Passage One
Questions 26 to 28 are based on the conversation you have just heard.
26.A) There were no planets without moons.
B) There was no air or water on Jupiter.
C) Life was not possible in outer space.
D) The mystery of life could not be resolved.
27.A) It has a number of active volcanoes.
B) It has an atmosphere like the earth’s.
C) It has a large ocean under its surface.
D) It has deep caves several miles long.
28.A) Light is not an essential element to it.
B) Life can form in very hot temperatures.

[原文]
Since early time. people have been fascinated with the idea of life existing somewhere else besides earth. Until recently, scientists believed that life on other planets was just a hopeful dream. But now they are beginning to locate places where life could form. In 1997, they saw evidence of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter. Space probes have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat. Water and heat from volcanic activity are two basic conditions needed for life to form. A third is certain basic chemicals such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lying at the bottom of Europa’s ocean. They may have already created life or may be about to. You may wonder if light is also needed for life to form. Until recently, scientists thought that light was essential. But now, places have been found on earth that are in total blackness such as eaves several miles beneath the surface. And bacteria, primitive forms of life. have been seen. there. So the lack of light in Europa’s sub-surface ocean doesn’t automatically rule out life forming.
Questions:
26. What did scientists once believe according to the passage?
27. What have scientists found about Europa, a moon of Jupiter?
28. What have scientists come to know recently about the formation of life?
[答案解析]
26．C
細(xì)節(jié)題。本題詢問“科學(xué)家曾經(jīng)(once)相信什么事實?”根據(jù)問題關(guān)鍵詞once可以定位到文章第二句的關(guān)鍵詞until recently．意為曾經(jīng)如何，過去一直認(rèn)為如何。原文是Until recently，scientists believed that life on other planets was just a hopeful dream．(過去科學(xué)家一直認(rèn)為其他星球上存在生命只是個美好的愿望。)也就是他們認(rèn)為外太空不可能存在生命，與答案C相符。A是說所有星球都會有衛(wèi)星，B是說木星上沒有空氣或水；D是說生命的奧秘不能被解開。所以C為正確答案。
27．C
細(xì)節(jié)題。本題詢問“科學(xué)家在Europa這個星球上找到什么?”根據(jù)問題關(guān)鍵詞Europa，a moon of Jupiter鎖定到文章中語句Space probes have provided evidence that Europa has a large ocean under its surface．(航空觀測鏡發(fā)現(xiàn)了此星球表面下有個大的海洋。)選項C與之相一致。A是說它有許多活火山；B是說它的大氣層和地球的相像；D是說它有好兒英里長的洞穴。所以C為正確答案。
28．A
細(xì)節(jié)題。本題詢問”科學(xué)家關(guān)于生命的形成最近發(fā)現(xiàn)了什么?”文章末尾提到Until recently，scientists thought that light was essential．But now，places have been found on earth that are in total blackness such as caves several miles beneath the surface．And bacteria．primitive forms of life，have been seen there．(科學(xué)家一直以為光對生命的存在是很重要的．但是現(xiàn)在他們發(fā)現(xiàn)在地球上深達(dá)數(shù)英里深的洞里是完全黑暗的，們也有細(xì)菌這種初級生命存在。)與選項A表述一致。B是說生命可以在很高的溫度下形成；C是說每種生命形式都在經(jīng)歷進(jìn)化；D是說氧氣對于有些生命形式來說是不需要的。所以A為正確答案。
