题目内容
12.Is there intelligent (有智力的) life on other planets?For years,scientists said"no"or"we don't know."But today this is changing.Seth Shostak and Alexandra Barnett are astronomers (天文学家).They believe intelligent life exists (存在) somewhere in the universe (宇宙).They also think we will soon contact(联系) these beings (生物).Why do Shostak and Barnett think intelligent life exists on other planets?The first reason is time.Scientists believe the universe is about 12billion years old."This is long enough for other planets to have intelligent life,"say Shostak and Barnett.The second reason is size-the universe is huge."Tools like the Hubble Telescope (哈勃望远镜) have shown that there are at least 100billion galaxies(星系),"says Shostak."And our galaxy,the Milky Way(银河系),has at least 100billion stars.Some planets going around these stars might be similar to the earth."
In the past,it was hard to look for signs of intelligent life in the universe.But now,powerful telescopes allow scientists to discover smaller planets-the size of Mars or Earth in other solar systems(太阳系).These planets might have intelligent life.
Have beings from space already visited Earth?"Probably not,"says Shostak."It's a long way away.However,intelligent beings may contact us in other way,such as radio signals (信号).In fact,they may be trying to communicate with us now,but we don't have the right tools to receive their messages.However,this is changing.By 2025,we could make contact with other life forms in our universe and we might help each other."

C.Because the astronomers were not interested in them.
D.Because the Milky Way didn't exist at that time.
84.Why haven't beings from space visited us yet according to Shostak?B
A.Because they're afraid of us.
B.Because it's a long way away.
C.Because they don't want to see us.
D.Because they don't know how to use radio signals.

分析 别的星球是否存在有智慧的生物?多年来,科学家们的答案都是"没有"或"我们不知道".但今天答案发生了变化.ShellShostak和AlexandraBarnett是天文学家,他们相信有智慧的生物存在于宇宙中的某处.他们也认为我们很快会联系到这些生物.
为什么Shostak和Barnett认为智能生物存在于其他星球上?第一个原因是时间.科学家认为宇宙大约一百二十亿岁."这个时间足够其他星球上产生智慧生物"Shostak和Barnett说.第二个原因是宇宙的大小,宇宙是巨大的."像哈勃望远镜这样的工具已经表明至少有100亿个星系,"Shostak说,"对于我们的银河系,至少有100亿颗星星.围绕他们自己星系中恒星转动的星球可能类似于地球.
在过去,很难在宇宙中寻找智慧生物.但现在,强大的望远镜允许科学家发现更小的行星,如火星或其他太阳系中地球的大小.这些行星可能有智慧生物.
有太空智慧生物到访过地球吗?"可能没有",肖斯塔克说,"这是一段很长的路.然而,智慧生物可以用其他方式,如无线电信号与我们联系.事实上,他们现在可能试图与我们联系,但是我们没有正确的工具来接收他们的信息.然而,这正在改变.到2025年,我们可以与宇宙中的其他生物获得联系,我们可以互相帮助."
解答 81.A.细节理解题.根据Seth Shostak and Alexandra Barnett are astronomers (天文学家).可知,句子中明确指明两位科学家是天文学家;因此答案为A.
82.C.细节理解题.根据第二段句首Why do Shostak and Barnett think intelligent life exists on other planets?以及后续的内容可知,本段先提出为什么两位天文学家确信有智慧生物存在,其次分条解释了原因,因此这段的主旨就是Why intelligent life might exist.
83.B.细节理解题.根据In the past,it was hard to look for signs of intelligent life in the universe.But now,powerful telescopes allow scientists to discover smaller planets-the size of Mars or Earth in other solar systems(太阳系).可知,在过去人们很难发现智慧生物的踪迹,但是现在不同了,因为人们发明了强大的望远镜,可以发现更小的星球,因此以前很难发现智慧生物的原因是强大的望远镜,即Because there were not any powerful telescopes.
84.B.细节理解题.根据最后一段的描述,智慧生命有没有到访过地球,答案是可能没有,紧接着Shostak给出了相应的解释"It's a long way away.",即与地球的距离很远,Because it's a long way away.因此答案为B.
85.C.词义猜测题.根据最后一段的内容,首先引出问题Have beings from space already visited Earth?即beings有没有到访过地球,Shostak的回答是可能没有,但是beings可能通过其他的方式联系我们,例如通过无线电信号,但是我们的工具不足以接收到这种信号,紧接说By 2025,we could make contact with other life forms in our universe and we might help each other.也就是到2025年,我们将与life forms取得联系,因此这里的life forms就是前面提到的beings,也就是句首提到的智慧生物,即intelligent beings.因此是C.
