二、阅读理解

From this issue,we explore why the Search for Extraterrestrial Intelligence (SETI) Institute hasn’t turned up anything since its founding in the 1980s.(See page 30 for more.)We asked our public account followers:Do you think that astronomers will find evidence of alien life in your lifetime?

LoranMcCormick:I think they already have it.Judging by the sudden industrialisation,I figure they found something that’s probably been here since before humans walked the Earth.

JensAvery:We may find life,but it may not want anything to do with us.We are not very advanced and can’t even get along with each other.

StevenBuhrow:I think the more important question is—will any government ever publicly admit it in our lifetime?I fully believe that we could discover alien life today and the government would simply say the public is not ready for this information.

JennaWalsh:I think we already see it,but just don’t realise what it is.Intelligent alien life probably doesn’t want anything to do with the disaster that is Earth at this point,so no doubt they’re playing it safe and observing from a safe distance.

ChristopherHarvey:By alien life,do you mean intelligent alien life?Then no.It would be extremely hard to find,short of them coming down to Earth.But if you mean unintelligent alien life,like bacteria or single cell,we might.

1.Why did we ask the public account followers the question?

A.To question the efficiency of SETI.

B.To confirm the appearance of aliens on earth.

C.To ensure the existence of aliens.

D.To complain about the failure to find aliens.

答案:A

解析:推理判断题。根据文章第一段“Fromthisissue,weexplorewhytheSearchforExtraterrestrialIntelligence(SETI)Institutehasn’tturnedupanythingsinceitsfoundinginthe1980s.”可知,SETI这个项目20世纪80年代后就没有现身说法了,可推断,问公众号的粉丝这个问题是质疑其是否取得进展。故选A项。

2.Whodoubtstheevervisitsofalienstotheearth?

A.LoranMcCormick.

B.StevenBuhrow.

C.JennaWalsh.

D.ChristopherHarvey.

答案:D

解析:细节理解题。根据ChristopherHarvey的陈述“Byalienlife,doyoumeanintelligentalienlife?Thenno.”可知,ChristopherHarvey否认了有智力的外星生物的存在。故选D项。

3.Wheredoesthistextprobablycomefrom?

A.Analbum.　 B.Asciencefiction.

C.Amagazine. D.Atravelguide.

答案:C

解析:推理判断题。根据全文内容可知,这一个问题和讨论,不会出现在专辑、科幻小说或者导游手册里,只可能出现在杂志上。故选C项。

三、完形填空

How big is space?That is a question man has been asking since the beginning of time.When your grandparents were in school,it was 　1　 that the universe was very 　2　 perhaps only 5,000 light years across.Around 500 years ago people considered that the universe was only a little bit 　3　 than Earth.In modern times with the 　4　 of technology we are finally starting to understand the immense(无边的)size of the universe,and it is much bigger than anyone 　5　 have ever imagined. 

Scientists cannot stretch(伸展)a measuring tape from Earth to a nearby star,so 　6　 do they know how far away they are?Scientists use something 　7　 parallax(视差).Parallax means 　8　 that they look at how much the stars move in the sky back and forth throughout the year as Earth circles the sun.This is not something 　9　 to you.In fact if you stretch out your hand in front of you and 　10　 your thumb,while 　11　 one eye,and then the other,your thumb will appear to move back and forth.Stars do the 　12　 thing,but our eyes are too close to see the 　13　.However,if we take a picture while on one side of Earth’s orbit,and then take another when we get to the 　14　 side of the orbit,then we have a large enough 　15　 that we can see the stars’ parallax,and determine how far away they really are. 

1.A.measured  B.bet

C.thought  D.proved

答案:C

解析:句意:当你的祖父母还在上学的时候,人们认为宇宙非常小。根据下文“Inmoderntimeswiththe　　　oftechnologywearefinallystartingto...”可推断,此处表达的是在祖父母上学时人们以为宇宙非常小。故选C项。

C.how  D.when

答案:C

解析:句意:那么他们怎么知道天体之间的距离有多远呢?根据下文可知,科学家用了“视差”这种方法来测量天体之间的距离,故此处表示科学家是如何知道他们离地球有多远。故选C项。

7.A.honoured  B.called

C.considered  D.believed

答案:B

8.A.actually  B.exactly

C.generally  D.simply

答案:D

解析:句意:视差简单地说,就是当地球绕着太阳转时,他们观察星星在天空中来回移动的程度。分析上下文可知,此处是简单地解释什么是视差。故选D项。

9.A.unacceptable B.unfamiliar

C.unbelievable  D.unnatural

15.A.distance  B.length

C.height  D.width

答案:A

解析:句意:那么我们就有足够大的距离可以看到恒星的视差。此处指的是有足够大的距离观察天体的视差。故选A项。
