Passage1

【答案与解析】这篇短文讲述了某些生物的迁移这一自然现象，并分析了迁移的原因。科学

家们最近又研究了龙虾海底成群结队迁移的现象。它们选择在每年天气不好的季节里进行迁

移，其中的原因及迁移的目的，科学家尚未弄清楚。

"mostanimals”这一关键词语，便可排除其它选项。在第一段最后一句中可找到答案的出

处。

“salmon”的情况在第二自然段中作了叙述。这种鱼出生在淡水中，后不到咸水地区居住，

在那里度过一生中绝大部分时光。到老了以后又回到它出生之时的淡水之中。仔细分析题干

中的“spendalonglife”和短文中的美键句"Thereitspendsitslife.”便可断定答案为A。

utheyleavetheirmountainhomeswhentheybecometoocrowded.M一句是答案的出处。

"salmon”

Passage2

【答案与解析】本文向我们介绍了有关彗星方面的知识。与地球一样，彗星也是绕太阳旋转

的，它本身不发光，靠反射太阳的光而发亮。短文中还介绍了彗星的成因，它拖着的长尾巴

是如何形成的以及著名的哈雷彗星名字的由来。

“Liketheearth,acometgoesroundthesun,but…”是判断本题的根据。

”•••iswaterfrozenintopiecesoficeandmixedwithironandrockdustandperhapsafewbig

piecesofrock.M这句话即能得出答案。

“Manypeopleperhapshaveseenacomet.n可知。

uSomecometsmoveoutofoursightandnevercomeback.Otherskeepcomingbackatregular

times.”一句是答案的出处。

u•••thelasttimeitcameclosetothesunandtheearthwasintheyear1986.”这句话的意思,即

可得到答案。

Passage3

【答案与解析】这篇短文介绍的是有关植物年轮方面的小知识。由于树木的生长要受到阳光、

降水等方面的影响，从一棵树上的年轮分布情况上，可以推断出树木所生长地方以前的气候

状况。年轮不仅对科学家研究地球上的气候环境有非常重要的参考价值，而且更为有趣的是，

它还能帮助科学家们研究人类的历史呢。

uIfthetenthringisfarfromtheeleventhring,thenwe'resurethatitwassunnyandrainymost

ofthatyear.一句即是答案所在。

“Doyouknowtheycantelluswhattheweatherwaslike--M和第三段的首句“Treeringsare

importantnotonlyforstudyingthehistoryofweather,,,M都有所暗示。

”•••tofindouttheweatheroftenyearsago,counttheringsofatreefromtheoutsidetothe

inside.Ifthetenthringisfarfromtheeleventhring…”一句中。

Passage4

【答案与解析】土壤是人类赖以生存的自然条件之一。没有了土壤或者是土壤受到了较为严

重的破坏，就会直接危及到人类的生存。本文在阐述土壤的成因、特性和重要性之后，呼吁

大家都要保护土壤。

“Thisdarksoilishumus,deadleaves,deadplantsandanimalwastemakeit,butthistakesalong

time."

uPeopleshouldgrowmoreandmoretreesandgrasstoslopwindfromcarryingthehumus

away."这一句话之中。

uWhenthehumushasbeenmade,plantscangrowwellinit."和"Itlakeshundredsofyearsto

makehumus,n这两句话所表达的意思，可知答案只能是D。

Passage5

【答案与解析】在大海的温水区域，我们常常可以发现一些珊瑚岛。本文向我们描述了珊瑚

岛形成的自然过程。文章最后，作者有感而发，以问句结束全文，发人深思，耐人寻味。

“在海中较暧和的水域，常有一些珊瑚岛”这一事实.A显然是不对的。

uAcoralislandisverynicetolookat.Itlookslikearingoflandwithtrees,grass,andflowerson

it.”这句话不难得出答案c

“Ineachoftheseholesaverysmallseaanimalhaslived.Theseseaanimalsmakethecoral.w—

句中。

uSometimesbirdsflewoveritandbroughtseedstotheisland.”这句话对此有明确的说明。

Passage6

【答案与解析】地震是地球上对人类生存构成威胁的最严重的自然灾害之一。科学家们经过

研究，发现了地震活动最频繁的地方。生活在地震带地方的人们可以采取适当的措施减少其

危害。也许，将来科学家们能在地震之前预测出发生的地点和时间。

uWhensomeplatesoftheearthmovesuddenly,anearthquakehappensM这一句明确告诉我们:

地球板块突然移动时，就导致地震的发生。选项A不是地震的成因，而是地震产生的结果。

这从4<,,,theshakingsmakerocksrisesuddenlyandevencrackopen”一句中可以看出。

Passage7

“Theearthtravelstwcnty-foui-hoursarounditsaxisonce.”这个句子可直接选出正确答案。事

实上，确切地说，地球自转一周所用的时间是23时48分46秒。

”•••butthesundoesn'treallydoso.Theturningoftheearthmakesusfeelasifthesunwere

movingacrossthesky.M这两句话中。选项D迷惑性较大，但是这利用由地理知识来排除。

“••"becauseeverythingelseontheearthisturningwithus”一句中。

**Whenourhalfoftheearthisfacingthesun,wesayitis'day'.Whenourhalfisawayfromthe

sun,wesayitis'night'这句话中face的意思，即它在此处用作动词（意思是“对着；面

向”），答案即可迎刃而解。

Passage8

【答案与解析】这篇短文告诉我们：雌蚊子吸过人的血之后，就会找一个地方去休息一下，

然后在叶子或墙上产下许多的卵。蚊子吮吸人的血液令人讨厌，但它对人血还很挑剔呢。有

的人，让它叮咬，它还不干呢。如果下一次蚊子叮了你，那说明你与众不同，倍受蚊子青睐。

“吸血”和“会飞”是mosquitoes的两个主要特征。根据这两个特点，联系生活常识，即

可选定答案。另外，读罢全文之后，也能将其余选项予以排除。

“Weknowthemosquitoverywell.Mosquitoesflyeverywhere.”一句是答案的出处。

“Butifshedoesn'tlikeyourblood,shewillturntosomeoneelseformoredeliciousblood.”这句

话之中。

u••,shelandsonyourbodywithoutlettingyouknow.Shebitesyousoquicklyandquietlythat

youmaynotfeelanythingdifferent.，?一句。

5.Bo其余三项在文中都有明确的说明。根据上面那个小题的内容，B项明显是错误的。

Passage9

【答案与解析】这篇短文向我们介绍了蜗牛的生活习性。无论是烈日当空，还是大雨滂沱，

蜗牛都会像整个冬季•样，呆在壳里睡觉。春天来临的时候，蜗牛就拖着三英寸长的身体从

壳里钻出来，靠它那灵敏的触角觅食。别看它的嘴比大头针尖大不了多少，却长着25万多

颗牙齿呢！

“Butmuchofthe（imesnailsdon'tmoveatall.Theyareintheirshells——sleeping."这句话，

显然只有D是正确答案。

“Hotsunwilldryoutasnail*sbody.Soattheleastsignofhotsun,asnaildrawsitsbodyinto

hisshell.”一句的意思，尤其是要仔细考虑关键词“into”对猜测词义的辅助作用，可知蜗

牛一旦碰到炙热的太阳，就会把身体蜷缩进壳里。

“Itseyes,at(heendofthetopfeelersareveryweak."这句话。

“Sowhenitrains,asnaildoesthesamething,too.w这句话中的"t
