Passage1

【答案與解析】這篇短文講述了某些生物的遷移這一自然現(xiàn)象，并分析了遷移的原因?？茖W

家們最近又研究了龍蝦海底成群結隊遷移的現(xiàn)象。它們選擇在每年天氣不好的季節(jié)里進行遷

移，其中的原因及遷移的目的，科學家尚未弄清楚。

"mostanimals”這一關鍵詞語，便可排除其它選項。在第一段最后一句中可找到答案的出

處。

“salmon”的情況在第二自然段中作了敘述。這種魚出生在淡水中，后不到咸水地區(qū)居住，

在那里度過一生中絕大部分時光。到老了以后又回到它出生之時的淡水之中。仔細分析題干

中的“spendalonglife”和短文中的美鍵句"Thereitspendsitslife.”便可斷定答案為A。

utheyleavetheirmountainhomeswhentheybecometoocrowded.M一句是答案的出處。

"salmon”

Passage2

【答案與解析】本文向我們介紹了有關彗星方面的知識。與地球一樣，彗星也是繞太陽旋轉

的，它本身不發(fā)光，靠反射太陽的光而發(fā)亮。短文中還介紹了彗星的成因，它拖著的長尾巴

是如何形成的以及著名的哈雷彗星名字的由來。

“Liketheearth,acometgoesroundthesun,but…”是判斷本題的根據(jù)。

”???iswaterfrozenintopiecesoficeandmixedwithironandrockdustandperhapsafewbig

piecesofrock.M這句話即能得出答案。

“Manypeopleperhapshaveseenacomet.n可知。

uSomecometsmoveoutofoursightandnevercomeback.Otherskeepcomingbackatregular

times.”一句是答案的出處。

u???thelasttimeitcameclosetothesunandtheearthwasintheyear1986.”這句話的意思,即

可得到答案。

Passage3

【答案與解析】這篇短文介紹的是有關植物年輪方面的小知識。由于樹木的生長要受到陽光、

降水等方面的影響，從一棵樹上的年輪分布情況上，可以推斷出樹木所生長地方以前的氣候

狀況。年輪不僅對科學家研究地球上的氣候環(huán)境有非常重要的參考價值，而且更為有趣的是，

它還能幫助科學家們研究人類的歷史呢。

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

【答案與解析】土壤是人類賴以生存的自然條件之一。沒有了土壤或者是土壤受到了較為嚴

重的破壞，就會直接危及到人類的生存。本文在闡述土壤的成因、特性和重要性之后，呼吁

大家都要保護土壤。

“Thisdarksoilishumus,deadleaves,deadplantsandanimalwastemakeit,butthistakesalong

time."

uPeopleshouldgrowmoreandmoretreesandgrasstoslopwindfromcarryingthehumus

away."這一句話之中。

uWhenthehumushasbeenmade,plantscangrowwellinit."和"Itlakeshundredsofyearsto

makehumus,n這兩句話所表達的意思，可知答案只能是D。

Passage5

【答案與解析】在大海的溫水區(qū)域，我們常?？梢园l(fā)現(xiàn)一些珊瑚島。本文向我們描述了珊瑚

島形成的自然過程。文章最后，作者有感而發(fā)，以問句結束全文，發(fā)人深思，耐人尋味。

“在海中較曖和的水域，常有一些珊瑚島”這一事實.A顯然是不對的。

uAcoralislandisverynicetolookat.Itlookslikearingoflandwithtrees,grass,andflowerson

it.”這句話不難得出答案c

“Ineachoftheseholesaverysmallseaanimalhaslived.Theseseaanimalsmakethecoral.w—

句中。

uSometimesbirdsflewoveritandbroughtseedstotheisland.”這句話對此有明確的說明。

Passage6

【答案與解析】地震是地球上對人類生存構成威脅的最嚴重的自然災害之一?？茖W家們經過

研究，發(fā)現(xiàn)了地震活動最頻繁的地方。生活在地震帶地方的人們可以采取適當?shù)拇胧p少其

危害。也許，將來科學家們能在地震之前預測出發(fā)生的地點和時間。

uWhensomeplatesoftheearthmovesuddenly,anearthquakehappensM這一句明確告訴我們:

地球板塊突然移動時，就導致地震的發(fā)生。選項A不是地震的成因，而是地震產生的結果。

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

Passage7

“Theearthtravelstwcnty-foui-hoursarounditsaxisonce.”這個句子可直接選出正確答案。事

實上，確切地說，地球自轉一周所用的時間是23時48分46秒。

”???butthesundoesn'treallydoso.Theturningoftheearthmakesusfeelasifthesunwere

movingacrossthesky.M這兩句話中。選項D迷惑性較大，但是這利用由地理知識來排除。

“??"becauseeverythingelseontheearthisturningwithus”一句中。

**Whenourhalfoftheearthisfacingthesun,wesayitis'day'.Whenourhalfisawayfromthe

sun,wesayitis'night'這句話中face的意思，即它在此處用作動詞（意思是“對著；面

向”），答案即可迎刃而解。

Passage8

【答案與解析】這篇短文告訴我們：雌蚊子吸過人的血之后，就會找一個地方去休息一下，

然后在葉子或墻上產下許多的卵。蚊子吮吸人的血液令人討厭，但它對人血還很挑剔呢。有

的人，讓它叮咬，它還不干呢。如果下一次蚊子叮了你，那說明你與眾不同，倍受蚊子青睞。

“吸血”和“會飛”是mosquitoes的兩個主要特征。根據(jù)這兩個特點，聯(lián)系生活常識，即

可選定答案。另外，讀罷全文之后，也能將其余選項予以排除。

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

“Butifshedoesn'tlikeyourblood,shewillturntosomeoneelseformoredeliciousblood.”這句

話之中。

u??,shelandsonyourbodywithoutlettingyouknow.Shebitesyousoquicklyandquietlythat

youmaynotfeelanythingdifferent.，?一句。

5.Bo其余三項在文中都有明確的說明。根據(jù)上面那個小題的內容，B項明顯是錯誤的。

Passage9

【答案與解析】這篇短文向我們介紹了蝸牛的生活習性。無論是烈日當空，還是大雨滂沱，

蝸牛都會像整個冬季?樣，呆在殼里睡覺。春天來臨的時候，蝸牛就拖著三英寸長的身體從

殼里鉆出來，靠它那靈敏的觸角覓食。別看它的嘴比大頭針尖大不了多少，卻長著25萬多

顆牙齒呢！

“Butmuchofthe（imesnailsdon'tmoveatall.Theyareintheirshells——sleeping."這句話，

顯然只有D是正確答案。

“Hotsunwilldryoutasnail*sbody.Soattheleastsignofhotsun,asnaildrawsitsbodyinto

hisshell.”一句的意思，尤其是要仔細考慮關鍵詞“into”對猜測詞義的輔助作用，可知蝸

牛一旦碰到炙熱的太陽，就會把身體蜷縮進殼里。

“Itseyes,at(heendofthetopfeelersareveryweak."這句話。

“Sowhenitrains,asnaildoesthesamething,too.w這句話中的"t
