in19.A.decisionB.situationC.subjectD.problem20.A.zooB.mountainC.museumD.laboratory答案：1.B从该段叙述的多来人们关于生存在喜马拉雅山上的雪人的传说就不难判断出此空应填story。2.D短文大部分描述的都是多来人们对于世界最高峰珠穆朗玛峰上有关雪人的存在情况的传说、考察和猜想,说明此空应填many years。3.Cheard from 表示“接到的信”;cared for表示“关心;照顾;喜欢”;knew of表示“知道;听说（不一定见过或认识）”;read about表示“读到;获悉”。当地人对珠穆朗玛峰上雪人的存在只不过是听说而已,却拿不出任何证据,故答案为C项。4.A当地人叙述雪人存在的一种更为真实的情况,因此,此空应填副词even,意思是“甚至”,用来加强语气,强调谓语动词,故答案选A项。5.B否定了主句叙述情况的真实性,表示的是让步意义,故此空应填一个表示让步意义的从属连词though,意思是“虽然,尽管”,引导一个让步状语从句。6.D从珠穆朗玛峰上雪人故事的发展情况可以看出,此空应填continued。7.Dentirely表示“整个地”;naturally表示“自然地”;clearly表示“清楚地”;simply表示“只是,仅仅”。如果填入前三个选项,则在某种程度上肯定了Eric Shipton在珠穆朗玛峰雪里所拍摄的照片是猴子或熊留下的足迹,这与下文the Abominable Snowman might really exist所表达的意思不符,所以此空只能填simply。8.Cfelt意为“感到”,不仅表示感官知觉,还表示情感或想法,填入此空才能与前一个谓语动词believed所表达的意思相符。9.Aexist表示“存在”;escape表示“逃跑”;disappear表示“消失”;return表示“返回”。由前一个宾语从句that they were not simply the tracks of a monkey or bear可以判断出此空应填exist。10.B人们在弄清雪人真相的努力中,所发现的惟东一西仅仅是更多的脚印,故此空应填表示数量的形容词more。11.C由下文“However,in 1964,a Russian scientist said that the Abominable Snowman was real.”可以推断出,大部分人认为,他们发现的更多的脚印只不过是普通动物的足迹。12.Bas they melted and refroze in the snow清楚地阐述了人们发现的更多的脚印要比普通的动物足迹大的原因。此空应填形容词large。13.D1964,俄罗斯科学家所说的与上句陈述情况是转折关系,故此空应填副词however。14.B前句叙述了“Most believe the footprints are nothing more than ordinary animal tracks.”我们可以判断出此空应填形容词real,一位俄罗斯科学家认为雪人是真的。15.C由短文第二段But.所表示的转折意义及空白后no evidence has ever actually been produced可以判断出,此空应填副词again,在句中作插入语,说明俄罗斯科学家所说的雪人的存在又一次没有真实存在的证据。16.B根据空白处在句子中But.所表示的转折意义和again一词对雪人存在证据的再次否定,就不难判断出此空应填actually。17.C当今有关雪人的故事已经冷落下来,仅有很少的人认真对待此事,故此空应填副词seriously,意为“严肃地,认真地”。18.Asucceed in表示“做成某事”;insist on表示“坚持”;depend on表示“依靠”;join in表示“参加”。由该句后面的主句可以推断出,条件状语从句所假定的是成功地捉住了雪人,故应选A项。19.D短文末句告诉我们,究竟把雪人放在何处？这是捉住雪人的人们所面临的一个难以抉择的现实问题,故此空应填problem。20.A人们对这种被认为生活在世界最高山喜马拉雅山上的所谓“雪人”,究竟属于人类还是属于动物还没有明确划分出来。如果把雪人划归人类,应该give it a room in a hotel;如果把雪人划归动物,自然应该放到动物园里去生活了,故此空应填zoo。.阅读理解AIts no secret that were into computers.And why not?On the Internet,we can catch up on news,plan vacations,pay bills and make friends.But for some,once
