的捕杀。故A项错误；其次句提到“Theyswimdownontheseafloor,whichgivesthemextracover.”海豹在海底潜游，因为深海会给海豹额外的爱护，在不得已的时候海豹才会游到海面上。故B项错误；第四句提到“Butwithallthesetricks,theycanstillbecleverlybeatenbythesharks.”，虽然海豹会玩一些小把戏，但仍旧会被鲨鱼奇妙地击败，句中cleverly说明白大白鲨的智力还是很高的。故D项错误；第四及第五句提到“Butwithallthesetricks,theycanstillbecleverlybeatenbythesharks.Usually,thesharkswilltakeonesealawayfromitsgroupandforceittoswimonthesurface,whereitiseasytohunt.”虽然海豹会玩一些小把戏，但大白鲨还是能够捕获到海豹，而且大白鲨还会把一头海豹赶上海面，这样捕食起来就会更简单了。C项正确。故选C。Ⅱ.读后续写阅读下面材料，依据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。Itwassomewherebetweenspringandsummer,mymomandIweredrivingthroughthecountryside.Backthen,Iwas13yearsold,andalwaysfeltunhappywithMom.ButlittledidIknowthatthistripwasgoingtobeaspecialone.Apotofflowerssatinthebackseat,whoseheavenlyscentfilledthecar.Suddenly,inthemiddleofnowhere,mymompulledover.“Whatareyoudoing？”Icried,fearingthatthecarhadbrokendownandwe'dbestuckthere,sofarfromhome.Butthatwasn'tthecase.Mymomhoppedoutofthecar,grabbingtheflowersfromthebackseat.“It'lljustbeaminute，”shecalledbackthroughtheopenwindows.Myeyesimpatientlyskimmedtheedgeoftheroadbeforesettlingonalittlesignshowingthatitwasanursinghome.Ilookedbacktothebuilding,somewhatannoyed,asmymomreappearedempty－handed.Beforeshestartedthecar,curiositydrovemetoask,“Doyouknowsomeonethere？”Sheshookherhead.“Thenwhatdidyoudowiththeflowers？”Shesmiledslightly,“Igavethemtothereceptionist.”“What？”Shelaughedatmyconfusion.“Itoldthereceptionisttogivetheflowerstowhoeverneededthem,especiallywhohasn'tgottenanyinawhile.”Ikeptsilentforamoment.Notlongafterwecontinuedourdriving,Ispokeagain,“Didyouleaveyourname？”Tothissheansweredinstantly,“No.Leavingflowersthereforsomeonewhowillappreciatethemmakesmefeelgood,whichisenoughofathankforme.”Suddenly,stillthinkingaboutMom'sdeeds,Iheardsomethingburstloudly.Itwasourcarthatbrokedown!Nothingcouldbeworse,becauseneithermymomnorIunderstoodhowtorepairit,andwedidn'tknowwherethegaragewas.Italsoseemedimpossibletowaitforanypasser－by,sincewehadseensofewalongtheway.Paragraph1：Wewereworryingaboutwhatcouldbedone.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Paragraph2：Aswedrovealong,aflowershopcameintosightontheroad._____________________________________________________________________________________________________________________________________________________________________________________________参考范文：Paragraph1：Wewereworryingaboutwhatcouldbedone.Butafterwaitinginvainforaconsiderabletime,Momand
