【答案解析】

本文講述中國正在竭力克隆瀕臨絕種的熊貓,這和TexasA&MUniversity的Noah'

sArk（諾亞方舟）工程極為相似，都是想拯救瀕臨滅絕的動物。

1.B。語義理解題。從第2段內(nèi)容可知，“諾亞方舟”工程的目標是把瀕臨滅絕的動物

的蛋（卵）、胚胎、精液和DNA儲存在液體氮中，如果某一種動物瀕臨滅絕時，將來可以重現(xiàn)

這一動物。

2.Ao細節(jié)題。從第6段第1句話Thenucleartransfer（核子移植）ofonespecie

stoanotherisnoteasy,andthelackofavailable（capableofbeingused）pa

ndaeggscouldbeamajorproblem可以做出正確判斷。

3.Co主旨題。從文章內(nèi)容來看，無論是中國還是世界克隆熊貓還沒有成功，所以排除

A、B項；D項內(nèi)容明顯與文章內(nèi)容不符，故排除。所以“探索克隆熊貓的可能性”應該是這

篇文章的標題。

4.Do判斷題。此題B項的干擾性較強，但由于它沒有說明是Chinesescientists,

所以應排除。A、C項明顯與原文不符。根據(jù)文章第3段第1句可知答案非D莫屬。

【答案解析】

本文主要講述人們將來可以通過網(wǎng)上看病，醫(yī)生可以根據(jù)病人的生理數(shù)據(jù)做出遠程診斷。

隨著第二代因特網(wǎng)和第三代移動手機為將來的遠程醫(yī)療服務，尤其是寬帶網(wǎng)交流價格的下降,

遠程醫(yī)療和醫(yī)藥信息、專家意見和診斷共享將成為家常便飯。

1.Ao主旨題。第2段和第3段的內(nèi)容，可知最佳答案為A。

2.Co細節(jié)題。從第2段第2句話中的…remotediagnosis（遠程診斷）willbebase

donrealphysiologicaldata（生理數(shù)據(jù)）fromtheactualpatient可以做出正確判斷。

3.Do判斷題。網(wǎng)上可以看病并不就是說病人去醫(yī)院不需要醫(yī)生，排除A項；通過電話

發(fā)送病人的信息是可行的，排除B項；現(xiàn)在至少有一個醫(yī)療隊想用遠程醫(yī)療來治療疾病，C

項也不對;根據(jù)文章最后?句話Withthefallingpriceofbroadbandcommunications,

thenewtechnologiesshouldstartanewtimewhentelemedicineandthesharing

ofmedicalinformation,experts*opinionsanddiagnosisarecommon可以肯定答

案是D。

4.A。推斷題。根據(jù)第4段第2句話Bandwidth（寬帶）isthelimitingfactorfor

sendingcomplex（復雜）medicalpicturesaroundtheworld一CTphotosbeingone

ofthebiggestbandwidthusers可知答案為A。

【答案解析】

本文報道了人們對法國地中海中的兩座城市沉如海底的各種推測。

1.Do推斷題。文章只對城市下沉的原因作了一些推測但未作出結論。由此可推知此題

答案為Do

2.Bo推斷題。根據(jù)文章中所提到的與之相關的名稱，如：Frenchunderwaterexplo

rerFranckGoddio,aParis-basedunderwaterresearchorganization,NapoleonJs

fleet可推知此題答案為Bo

3.Do推斷題。文章討論地中海中的兩座城市下沉的原因，顯然與地質科學有關，故選

Do注意不宜選A,一個顯然的因素是第1段中出現(xiàn)的yesterday。

【答案解析】

本文介紹了個觀點：母性特點能使婦女變得更加聰明靈敏。

1.C?細節(jié)題。根據(jù)Testsonratsshow-可知科學家是通過做老鼠實驗得出這個結

論的。

2.A?詞義猜測題。后面的對比whohavenobabies,實際上提供了一個相反的情況，

所以我們可以推測thosewhoraisetwoormorelittersofpups中的littersofpups

指的是“剛出生不久的小老鼠”。

3.Bo細節(jié)題。根據(jù)文章第3段中的,?,thehormonesofpregnancy（懷孕）arepro

tectingthebrain可得出答案。

4.C?句意理解題?？茖W家通過用老鼠做實驗來說明人的問題。因為人和老鼠都屬于哺

乳動物，很多生理機能都相同。

5.B。主旨題。短文第1句Motherhoodmaymakewomensmarter是主題句，據(jù)此我

們可以得出答案。
