题目内容
20.Think stars don't move?Think again!When you look into the sky at night,the stars may appear to stay in the same place.But stars are always on the move-they're just so far away that the motion is hard to see.But some stars move in ways that appear too strange to be real.In 2005,astronomer Warren Brown found one of these space oddities(奇特,怪事).It was-located on the outer edge of the Milky Way,the galaxy we live in.The star was speeding away like nothing he'd ever seen.
"It seemed absurd (荒谬的,荒诞的).No star in the galaxy has a speed like that,"Brown remembers."I thought,oh my goodness,I have something kind of special here."
No one had ever seen a star like this one.What does a scientist do when the results don't make sense?
Brown didn't give up.Instead,he kept looking.And he kept finding more of these strange and speedy stars,called hypervelovity stars.Hyper means"above"and velocity has to do with speed.He and his team just found six more of these"above speed"stars,bringing the total to 16.And,he says,he's found even more,and is just waiting for the scientific community to confirm them.
51.If you look at the stars in the sky,they often appearB.
A.movable all the time
B.still in one place
C.moveable sometimes
D.still only for a while
52.In 2005,astronomer Warren Brown foundA.
A.a star was speeding away very fast
B.a star was moving away very slowly
C.some stars were not real
D.some stars were not in the Milky Way
53.Which of the following is TRUE?C
A.Stars never move at all
B.No star in the galaxy has a fast speed.
C.It's hard to see the stars moving.
D.Brown has never seen something special.
54.The underlined word"hypervelocity"in the last paragraph probably mean."B"
A.均速的
B.超速的
C.超重的
D.超常的
55.The writer writes this passage to tell usC.
A.something about an astronomer
B.where the Milky Way is
C.something about the speedy stars
D.how scientists do their research.
分析 认为星星是不会移动的?那再想一想吧!当你看晚上的天空时,星星可能看起来是在一个地方的.但是星星总是处在移动中的--它们是如此的遥远以至于它们的移动很难被看到.
但是一些星星的移动方式看起来是如此的奇怪以至于让人怀疑它的真实性.在2005年,天文学家Warren Brown发现了天空中的一件奇怪的事.它发生在银河系的外部边缘处,就是我们所处的星系.这颗星星以他从来没有见过的速度快速的移动."它看起来是荒谬的.在星系中没有星星有像那样的速度,"Brown记得."我认为,我的天哪,我发现了一些特殊的事情."
没有人曾经看到过一颗像这样的星星.当结果毫无意义的时候,科学家们怎么办呢?
Brown 没有放弃,相反的,他继续观察.之后他发现了更多的这样奇怪的加速的星星.他把它们命名为超速行星.Hyper意味着"在…上",velocity与速度相关.他和他的队伍又发现了另外六个更多的"超速"行星,把总数上升到了16个.并且,他说道,他已经发现了更多,只等待着科学的团队来确认.
解答 51.B 细节理解题 根据文章"When you look into the sky at night,the stars may appear to stay in the same place.But stars are always on the move-they're just so far away that the motion is hard to see."(当你看晚上的天空时,星星可能看起来是在一个地方的.但是星星总是处在移动中的--它们是如此的遥远以至于它们的移动很难被看到.)知行星看起来是在一个地方的,故选B.
52.A 细节理解题 根据文章"In 2005,astronomer Warren Brown found one of these space oddities(奇特,怪事).It was-located on the outer edge of the Milky Way,the galaxy we live in.The star was speeding away like nothing he'd ever seen."(在2005年,天文学家Warren Brown发现了天空中的一件奇怪的事.它发生在银河系的外部边缘处,就是我们所处的星系.这颗星星以他从来没有见过的速度快速的移动.)故知为发现了一颗快速移动的星星.故选A.
53.C 判断正误题 根据文章"But stars are always on the move"(但是星星总是处在移动中的)知选项A 错误,根据文章"It was-located on the outer edge of the Milky Way,the galaxy we live in.The star was speeding away like nothing he'd ever seen."(它发生在银河系的外部边缘处,就是我们所处的星系.这颗星星以他从来没有见过的速度快速的移动.)知选项B 错误,根据文章"I have something kind of special here."(我发现了一些特殊的事情.)知选项D错误,根据文章"But stars are always on the move-they're just so far away that the motion is hard to see."(但是星星总是处在移动中的--它们是如此的遥远以至于它们的移动很难被看到.)故选项C正确.故选C.
54.B 推测词意题 根据文章"Hyper means"above"and velocity has to do with speed.(Hyper意味着"在…上",velocity与速度相关.)故知可推知hypervelocity意为超速的.故选B.
55.C 文章大意题 根据整篇文章大意并结合关键句And he kept finding more of these strange and speedy stars,called hypervelocity stars.(之后他发现了更多的这样奇怪的加速的星星.他把它们命名为超速行星.)可以推测文章讲述的是关于超行星的事,故选C.
点评 这是一篇逸闻趣事类的阅读理解题.题型有细节理解题、推测词意题、判断正误题及文章大意题.考生在做题的过程中针对不同的题型采用不同的方法.比如对于51、52小题考生需要从文章中找出对应的句子,根据细节进行判断.53小题则需考生可运用排除法,找出文章中的依据,逐一排除,54小题需结合单词所在上下文作出判断.55小题则需要考生从整体上理解全文.考生需根据具体问题采取不同的答题方法.
