B．foundC．liked D．knew解析：選D。作者剛到一個陌生的地方，肯定不認識什么人，knew認識。故選D。2．A.noticing B．missingC．meeting D．introducing解析：選B。由于作者開始感到孤獨寂寞，那自然而然就會思念在家鄉(xiāng)的朋友，因此missing是最佳答案，其他選項均不符合邏輯。3．A.college B．hometownC．theeast D．thewest解析：選A。由此空后面的．..fortheeducationIshouldhavegottenlongago.Ilovetalking；that’swhyIenjoygoingtoschoolsomuch...可知，作者是去了一所大學里面學習。故選A。4．A.duty B．formC．opportunity D．time解析：選C。根據(jù)上下文語境，由于作者喜歡說話，去了大學正好給了自己認識新朋友的機會。故選C。其他選項皆不符合原文邏輯。5．A.plane B．trainC．car D．bus解析：選D。仔細閱讀第三段的最后一句OverthenextfewdayswheneverIgotonthebusshewasalwaysthereandwewouldtalk.可知是在汽車上。故選D。6．A.discussion B．conversationC．quarrel D．debate解析：選B。根據(jù)下上文語境可知，作者與這位老太太的談話非常愉快，因此可以推斷出，A、C、D都不符合邏輯和題意，只有B項最符合語境。7．A.valuable B．freeC．safe D．wonderful解析：選D。haveawonderfultime過得很愉快。8．A.pointed B．shoutedC．smiled D．stared解析：選C。根據(jù)上下文可知，作者第一次與老太太交談之前，曾對她微笑(Ismiledather...)，此空后面有個關鍵詞(again)，因此選C。9．A.pickedup B．blewawayC．brokedown D．leftout解析：選A。pickup撿起，中斷后重新開始；leaveout忽視，不考慮。此處表示作者又一次見到老太太，于是接著上次結束的話題重新開始交談。故選A。10．A.expect B．studyC．see D．discover解析：選C。根據(jù)上下文語境，后來作者休息了一陣，沒有去學校，因此就沒怎么見到這位新的年老的朋友。見到某人，一般用see。故選C。11．A.calledon B．ranintoC．waitedfor D．laughedat解析：選B。callon拜訪，號召；runinto突然遇到；waitfor等候，等待；laughat嘲笑。根據(jù)上下文語境，作者已經(jīng)有一段時間沒有見到自己的新朋友，想不到有一天在一個中轉站突然遇到她。因此B項最合適。12．A.talking B．facingC．drinking D．explaining解析：選A。根據(jù)第7小題可知，老太太對與自己的聊天感到非常愉快，因此此處用talking與上文呼應。13．A.won B．worriedC．touched D．saved解析：選C。老太太覺得與作者的交談非常愉快，于是作者非常感動(touched)。其他選項都不符合文章邏輯。14．A.age B．a(chǎn)ddressC．name D．number解析：選D。作者的朋友到底想要什么呢？從下面的提示可以看出，她是想在沒有機會在車上遇到的時候也可以跟作者聊天，因此她想要的應是電話號碼(number)。故選D。15．A.come B．meanC．go D．get解析：選C。此題有點難度，howfarsth.cango...……多么有用，……有很大的意義。最后一句就是講一個笑容或者一句溫暖和善的話語就能夠讓你愉快一天。其他選項都沒有這個意思。故選C。Ⅱ.語法填空Amongallthefastgrowingscienceandtechnology，theresearchofhumangenes，1.____________geneticengineeringaspeoplecallit，isdrawingmoreandmoreattentionnow.Sometimesitisahottopic2.____________(discuss)bypeople.Thegreatestthingthatgenetechnologycandoistocureseriousdiseasesthatdoctorsatpresentcanalmostdonothingwith，suchascancerandheartdisease.Everyyear，millionsofpeoplearemurderedbythesetwo3.____________(kill)．Andtodate，doctorshavenotfound4.____________effectivewaytocurethem.Butifthegenetechnology5.____________(apply)，notonlythesetwodiseasescanbecuredcompletely，6.____________(bring)happinessandmorelivingdaystothepatients，butalsothegreatamountofmoneypeoplespendoncuringtheirdiseasescanbesaved，so7.____________benefitstheeconomyaswell.Inaddition，humanlifespan(壽命)canbeprolonged.Genetechnologycanhelppeopletogivebirthtomorehealthyandcleverchildren.Somefamilies，withtheEnglishimperialfamilybeingagoodexample，havehereditarydiseases.Thismeanstheirchildrenwillforsurehavethefamilydisease，8.____________isagreattroubleforthesefamilies.Inthepast，doctorscoulddonothingabouthereditarydiseases，9.____________genetechnologycansolvethisproblem10.____________(perfect)．Thescientistjustneedstofindthewronggeneandcorrectit，andahealthychildwillbeborn.【文章大意】本文講述了基因工程的重要作用，它有利于人類治療疾病和生育更多健康的小孩。1．解析：geneticengineering是對前面humangenes的解釋說明，所以用or作插入語。答案：or2．解析：discuss與hottopic之間構成動賓關系，所以用過去分詞作后置定語。答案：discussed3．解析：cancerandheartdisease是兩大“殺手”。答案：killers4．解析：句中way是可數(shù)名詞，且表示泛指，所以在effective前加an或any。答案：an/any5．解析：if引導的條件狀語從句中用一般現(xiàn)在時代替一般將來時，且apply與thegenetechnology之間是動賓關系，所以用一般現(xiàn)在時的被動語態(tài)。答案：isapplied6．解析：用現(xiàn)在分詞表示伴隨。答案：bringing7．解析：it指代上文提到的thegenetechnology。答案：it8．解析：這是個非限制性定語從句，從句中缺少主語，且指物，所以用關系代詞which。答案：which9．解析：前后句之間是轉折關系，所以用表示轉折關系的并列連詞but。答案：but10．解析：副詞修飾動詞。答案：perfectlyⅢ.閱讀理解Withonlyabout1,000pandasleftintheworld，Chinaisdesperatelytryingtoclonetheanimalandsavetheendangeredspecies(物種)．That’samovesimilartowhataTexasA&MUniversityresearchershavebeenundertakingforthepastfiveyearsinaprojectcalled“Noah’sArk”(諾亞方舟)．Noah’sArkisaimedatcollectingeggs，embryos(胚胎)，semen(精液)andDNAofendangeredanimalsandstoringtheminliquidnitrogen.Ifcertainspeciesshouldbecomeextinct，Dr.DuaneKraemer，aprofessorinTexasA&M’sCollegeofVeterinaryMedicine，saystherewouldbeenoughofthebasicbuildingblockstoreintroducethespeciesinthefuture.Itisestimatedthatasmanyas2,000speciesofmammals，birdsandreptiles(爬行動物)willbecomeextinctinover100years.Thepanda，nativeonlytoChina，isindangerofbecomingextinctinthenext25years.Thisweek，ChinesescientistssaidtheygrewanembryobyintroducingcellsfromadeadfemalepandaintotheeggcellsofaJapanesewhiterabbit.Theyarenowtryingtoimplanttheembryointoahostanimal.Theentireprocedurecouldtakefromthreetofiveyearstocomplete.“Thenucleartransfer(核子移植)ofonespeciestoanotherisnoteasy，andthelackofavailablepandaeggscouldbeamajorproblem，”Kraemerbelieves.“Theywillprobablyhavetodoseveralhundredtransferstoresultinonepregnancy.Ittakesalongtimeandit’sdifficult，butthiscouldbegroundbreakingscienceifitworks.Theyarecertainlynotputtinganylivepandasatrisk，soitisworththeeffort，”addsKraemer，whoisoneoftheleadersoftheProjectatTexasA&M，thefirst-everattemptatcloningadog.“Theyaretryingtodosomething；that’sneverbeendone，andthisisverysimilartoourworkinNoah’sArk.We’rebothtryingtosaveanimalsthatfaceextinction.Icertainlyappreciatetheireffortandthere’salotwecanlearnfromwhattheyareattemptingtodo.It’saresearchthatisverymuchneeded.”【文章大意】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．Theaimof“Noah’sArk”projectisto________.A．makeeffortstoclonetheendangeredpandasB．saveendangeredanimalsfromdyingoutC．collectDNAofendangeredanimalstostudyD．transferthenuclearofoneanimaltoanother解析：選B。語意理解題。從第一段內容可知，“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儲存在液態(tài)氮中，如果某一種動物瀕臨滅絕，將來可以重現(xiàn)這一動物。2．AccordingtoProfessorKraemer，themajorproblemincloningpandaswouldbethelackof________.A．a(chǎn)vailablepandaeggsB．hostanimalsC．qualifiedresearchersD．enoughmoney解析：選A。細節(jié)題。從第三段第二句“Thenucleartransfer(核子移植)ofonespeciestoanotherisnoteasy，andthelackofavailablepandaeggscouldbeamajorproblem，”可以作出正確判斷。3．Thebesttitleforthepassagemaybe________.A．China’sSuccessinPandasCloningB．TheFirstClonedPandaintheWorldC．ExploringthePossibilitytoClonePandasD．China－theNativePlaceofPandasForever解析：選C。主旨題。從文章內容來看，無論是中國還是世界，克隆熊貓都還沒有成功，所以排除A、B項；D項內容明顯與文章內容不符，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．Fromthepassageweknowthat________.A．KraemerandhisteamhavesucceededincloningadogB．scientiststrytoimplantapanda’seggintoarabbitC．KraemerwillworkwithChinesescientistsincloneresearchesD．a(chǎn)bouttwothousandofspecieswillprobablydieoutinacentury解析：選D。判斷題。此題C項的干擾性較強，但由于沒有說明是Chinesescientists，所以應排除。A、B項明顯與原文不符。根據(jù)文章第二段第一句可知答案非D莫屬。5．Theunderlinedword“extinction”inthelastparagraphofthepassagemeans________inChinese.A．熄滅 B．絕跡C．消滅 D．絕種解析：選D。絕種。Ⅳ.基礎寫作最近你們班舉行了一次英文辯論會，討論現(xiàn)在同學們交作業(yè)的各種方式及其利弊問題。以下是這次討論的內容。eq\x(\a\al(傳統(tǒng)方式：,統(tǒng)一交辦公室，單獨面批,支持方：簡單、實用，利于老師和學生面對面交流；,反對方：單調，不利于學生的個性發(fā)展；,新型方式：,發(fā)到老師郵箱,支持方：便捷，利于掌握現(xiàn)代科技；,反對方：沉溺于網(wǎng)絡，耽誤學業(yè)))【寫作內容】請根據(jù)以上內容寫一篇英語短文，內容包括：1．介紹同學們交作業(yè)的方式；2.兩種交作業(yè)方式的利與弊?！緦懽饕蟆?．只能用5個句子表達全部內容；2．文章開頭和結尾已經(jīng)給出，不計入寫作總句數(shù)?！驹u分標準】句子結構準確，信息內容完整，篇章連貫。Recentlyourclassheldaheateddiscussion，whichisaboutthewaysofhandinginhomework._____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
