B．Whitebread.C．Hamandsausage. D．Fruitandvegetables.答案：D解析：細(xì)節(jié)理解題。根據(jù)第四段中Healsousedtosnackonchips,whitebreadandsometimesslicesofhamorsausage,andnotreallyanyfruitandvegetables.可知，他還經(jīng)常吃薯片，有時(shí)吃幾片白面包，偶爾吃幾片火腿，不吃任何水果和蔬菜。所以小男孩拒絕吃水果和蔬菜，故選D項(xiàng)。3．WhatcanwelearnfromDrAtan'swords?A．Vegetablesandfruitaretheonlysourceofvitamins.B．Lackofvitaminsandmineralsmayleadtothelossofsigh.C．Themorevitaminswetake,thebetter.D．Lossofmineralsfrombonecausesblindness.答案：B解析：推理判斷題。根據(jù)第六段、第七段中hewaslowinB12aswellassomeotherimportantvitaminsandminerals—copper,seleniumandVitaminD.“Hehadblindspotsrightinthemiddleofhisvision，”saidDrAtan'sassistant.可知，少年體內(nèi)的維生素B12以及其他一些重要的維生素和礦物質(zhì)——銅、硒和維生素D含量都很低。DrAtan醫(yī)生說這個(gè)少年的視力正中間有盲點(diǎn)。所以通過DrAtan的話可以判斷出，缺乏維生素和礦物質(zhì)可能導(dǎo)致失明，故選B項(xiàng)。BSomeyearsago,MichelAndréfoundhimselfstaringatthebodyofadeadwhaleonabeachintheCanaryIslands.Itwasobviousthattheanimalhadbeenstruckviolentlybyaship—butwhy?Onlylater,aftersurveyingthewhaleswhichlivedintheareaandmeasuringtheincreaseofsoundpollutionfromshipsdiditbeeclearthattherewasalink.Thewhaleshadbeedesensitisedtothenoiseofapproachingboatsandwerebeingstruckbythem,oftenseriously.“Weneverthoughtthatthiscouldbesomethingthatcouldkill，”recalls(回憶起)André，whoisthedirectoroftheLaboratoryofAppliedBioacousticsattheTechnicalUniversityofCatalonia,Barcelona.Andréhasspent20yearsdevelopinganadvancedsystemtobetterunderstandwhyincidentslikethishappen.Hisunderwatermicrophoneshaveexposedaworldofdeafeningsoundandanimalmunicationneverobservedwithsuchclarity(清晰)before.Itwasnotaneasytask.Soundwavesdon'ttravelthroughwaterintheuniform,predictablewaytheydothroughtheair.Instead,thetemperature,salinity(鹽度)andflowofwaterhavegreateffectsontheirpath.Whatcanbedone?Onesolutionistochangeshippingroutestocoursewhereshipsarestatisticallylesslikelytomeetanimals.It'salsopossibletoslowshipsdownto18km/horless,whichislesslikelytoseriouslyinjureawhale.Asfordealingwiththerootcauseoftheproblem,theUN'sInternationalMaritimeOrganisationhasalreadypublishedguidelinesonhowtoquietenships,butitwillbeawhilebeforetheeffectsofsuchchangesmightbeobserved.“Theoceanisnotourworld，”mentsAndré.Butitisourstolookafter.Andthankstohiswork,wecanbetterunderstandtheeffectsofsubseasoundpollution.本文是一篇說明文，文章通過介紹MichelAndré的發(fā)現(xiàn)，講述了海底聲污染對于鯨魚的影響以及相應(yīng)的應(yīng)對措施。4．Whatdoestheunderlinedword“desensitised”inParagraph2mean?A．Stubborn.

D．Uncaring.答案：C解析：觀點(diǎn)態(tài)度題。根據(jù)最后一段第三句中的“thankstohiswork,wecanbetterunderstandtheeffectsofsubseasoundpollution”可知，作者對MichelAndré所做的工作持積極態(tài)度，故C項(xiàng)正確。thanksto意為“多虧，由于”。7．Whatisthetextmainlyabout?A．Agreatexpert.B．Noiseinthesea.C．Animalsinthesea.D．Seaexplorationtechnology.答案：B解析：主旨大意題。通讀全文可知，文章通過介紹MichelAndré的工作，講述了海底噪音對鯨魚的影響以及降低海底噪音的措施，故B項(xiàng)最符合文章主旨。Ⅱ.七選五Ifyoufindyourselflosingthemotivationtodoyourhomework,youarenotalone.__1__Ifyouwanttogetgoodgrades,ofcourse,youmustdoyourhomework.Here'showtofindthemotivation：__2__Ifyouaretootired,you'lljustwanttowatchtelevisioninsteadofthinkingaboutyourhomework.Plusyou'llhaveamucheasiertimerememberingwhatyou'vereadifyouareenergetic.Turnoffthedistractions.Turnoffthemusicandtelevision.Ifyoudon'tneedyourputerortheInternetforyourhomework,turnitoffaswell.Makesureyourstudyareaisfreefromdistractions.__3__Startrightaway.Doingyourhomeworkrightafteryougethomecankeepyoufromfallingintothetrapofendlesshoursofdistractions.__4__AlthoughitmaynotbepopulartodoyourhomeworkonaFridaynight,you'llhavetherestoftheweekendfree.Createaschedule.__5__Planoutwhenyouwilldoeachpartoftheassignment.Splitthemintosmallparts,sothatyoucanfeelgoodaboutpletingeachpart.Itcanbemucheasiertodealwithabigassignmentorprojectonceyou'vesplititintomanageablepieces.Homeworkcanbeboring,butit'snecessaryifyouwanttopassyourclasses.Onceyoumakeaplantofinishyourhomework,sticktoit.A．Getenoughrest.B．Gatheryourmaterials.C．Writeallofyourassignmentsonachecklist.D．Manystudentsdelayindoingtheirhomework.E．You'lleasilygetdistractedandavoidfinishingyourhomework.F．Plusthematerialyou'velearnedwillstillbefreshinyourmind.G．You'llbeabletofinishyourhomeworkmuchfasterifyoucanfocusonit.有不少學(xué)生缺乏做家庭作業(yè)的積極性，本文就如何提高學(xué)生做家庭作業(yè)的積極性給出了一些簡單但行之有效的應(yīng)對策略。1．D解析：根據(jù)第一段“Ifyoufindyourselflosingthemotivationtodoyourhomework,youarenotalone”以及下文給出的幾個(gè)方法可推知，該空應(yīng)是說明許多學(xué)生做家庭作業(yè)缺乏積極性的情況，故選D項(xiàng)。2．A解析：分析文章結(jié)構(gòu)和空處所在的位置可知，本空是該段的主題句。根據(jù)本段的兩個(gè)假設(shè)“Ifyouaretootired”和“ifyouareenergetic”可推知，本段的建議是要休息好，故選A項(xiàng)。3．G解析：根據(jù)空前一句可知，要確保你的學(xué)習(xí)區(qū)域沒有分散注意力的事物，由此可推知，沒有了分散注意力的事物的干擾，你就會關(guān)注家庭作業(yè)，這樣你將能更快地完成它，故選G項(xiàng)。4．F解析：承接前一句“Doingyourhomeworkrightafteryougethome...endlesshoursofdistractions”可知，該空應(yīng)是進(jìn)一步說明回家后立刻做家庭作業(yè)的好處，故選F項(xiàng)。5．C解析：根據(jù)該段的主題句“Createaschedule”，并和后一句中的“Planout”和“assignment”形成呼應(yīng)可知，此處表示在創(chuàng)建一個(gè)計(jì)劃時(shí)，要把所有的任務(wù)寫在一個(gè)清單上，故選C項(xiàng)。Ⅲ.語法填空NewYorkissamplingsomeofthedelicacies(佳肴)thatpopupintheoffice,eitherwhenstaffersreturnfromChina__1__whenthegoodiesarecookedrighthere.Therearetheannualholidayservingsofbaoziandjiaozianda__2__(various)oftreatscontainingbeanpaste.Theyallhaveuniquetastes.ThisweekIgottotrysomethingnew:gojiberries,also__3__(know)aswolfberries,alongwithcookie-typetreatsbasedonthebrightfruit.HuHe,oneofChinaDaily'swebsiteeditorscurrently__4__(work)inNewYork,gavemeandothercolleagueseachasupply__5__gojiberries.AndIenjoyedtheentirebottleinafewdays.Gojihasbeenregardedasa__6__(tradition)healthsupplementbyChinesepeople.Inrecentyears,thedemandforgojihasbeenrisingandwe__7__(see)increasingnumbersofbuyersfromoverseas.WhyamIgoingonaboutgojiberries?Itturnsoutthattheyhavemanyprettygoodhealth__8__(benefit):They
