说是……的”。其中it是形式主语，真正的主语是后面的动词不定式。故填toprotect。（2）TheGreatWallisoneofthegreatestwondersintheworld.Everyyear,millionsoftouristscometovisitit.Ithasalonghistoryofmorethan2,000years.Thewallwasbuilttoprotectthecountryfromenemies.Today,itisnotonlyasymbolofChinabutalsoaplaceforpeopletolearnaboutChinesehistory.Weshouldbeproudofourgreatcultureandtryourbestto1______itwell.答案：protect解析：根据句意“我们应该为我们的伟大文化感到自豪，并尽力好好______它”，结合前文提到的长城是用来保护国家的，以及常识，此处应填“保护”。tryone'sbesttodosth.为固定搭配，故填动词原形protect。（3）Look!Theboys______(play)footballontheplayground.答案：areplaying解析：句首的Look!提示动作正在发生，应使用现在进行时。主语Theboys是复数，故谓语动词用areplaying。（4）Look!Theboys______(play)footballontheplayground.答案：areplaying解析：句首的Look!是现在进行时的标志词，表示动作正在发生。主语Theboys是复数，因此谓语动词应用areplaying。（5）Weshouldprotecttheenvironmentbecauseitisimportantforour______(survive).答案：survival解析：空格前是形容词性物主代词'our'，后面应接名词形式。survive是动词，其名词形式为survival。句意：我们应该保护环境，因为它对我们的生存很重要。故填survival。（6）Neitheroftheboys____(be)interestedinplayingchess.答案：is解析：本题考查主谓一致。neitherof+复数名词/代词作主语时，谓语动词通常用单数形式（口语中有时也用复数，但在考试中标准答案通常为单数）。本句描述的是现在的状态，用一般现在时，故填is。（7）根据句意及首字母提示完成单词：Itisimportantforustokeepabalancedd______tostayhealthy.答案：diet解析：句意：为了保持健康，保持均衡的饮食对我们来说很重要。根据首字母d和语境“保持健康”，可知此处指“饮食”，故填diet。（8）Mymotheraskedmetobuysome______(tomato)fordinner.答案：tomatoes解析：some后面接可数名词复数或不可数名词。tomato是可数名词，其复数形式是以o结尾有生命的名词，需加es，即tomatoes。故填tomatoes。（9）Mybrotherisgoodat______(swim).Hewantstojointheswimmingclub.答案：swimming解析：本题考查固定搭配begoodatdoingsth.（擅长做某事）。at是介词，后接动词时需用动名词形式。swim的动名词需双写m再加ing，即swimming。（10）Therearemany______(tomato)inthebasket.答案：tomatoes解析：本题考查名词复数。many修饰可数名词复数。tomato是以o结尾的名词，且表示有生命的事物，其复数形式需加-es，即tomatoes。故填tomatoes。（11）Therearemany______(child)playinginthepark.答案：children解析：many修饰可数名词复数。child是不规则名词，其复数形式为children。三、​完形填空（5题）（1）Tomisamiddleschoolstudentwholovesreading.Everyweekend,hegoestothecitylibrary.OneSaturdaymorning,hefoundabookaboutspaceexploration.Hewassoexcitedthathestartedreadingitimmediately.Thebookdescribedhowastronautsliveandworkinspace.Tomlearnedthattheyhavetoexerciseeverydaytokeeptheirbodiesstrongbecausethereisnogravity.Healsoreadaboutthechallengestheyface,suchassleepinginfloatingbagsandeatingspecialfood.Tomwasamazedbythebraveryoftheastronauts.Hedecidedtostudyharderinscienceclasses.Hedreamsofbecominganastronautoneday.Hisparentssupporthisdreamandoftenbuyhimbooksaboutscience.Tombelievesthatwithhardwork,hisdreamwillcometrue.Thisstoryshowsthat1______caninspireyoungpeopletopursuetheirgoals.Readingnotonlyprovidesknowledgebutalsoopensupnewworldsforus.Ithelpsusunderstandthingswecannotseeinourdailylives.ForTom,thelibraryisnotjustaplacetoborrowbooks,butagatewaytohisfuture.Heencourageshisfriendstoreadmore,sayingthatbooksarelike2______thattakeustodifferentplaceswithoutmovingourfeet.Throughreading,Tomhasbecomemorecuriousandconfident.Henowparticipatesactivelyinclassdiscussionsandshareswhathehaslearnedwithothers.Histeacherspraisehimforhisbroadknowledge.Tom'sexperienceprovesthatreadingisapowerfultoolforpersonalgrowth.Itshapesourcharacterandexpandsourhorizons.Therefore,weshouldalldevelopthehabitofreadingfromayoungage.Whetheritisfictionornon-fiction,everybookhassomethingvaluabletooffer.LetusfollowTom'sexampleandexploretheworldthroughbooks.答案：1.books2.wings解析：1.通读全文可知，文章主要讲述阅读对Tom的影响。第一空所在句总结上文，指出“书籍”能激励年轻人追求目标，故填books。2.第二空是一个比喻句，说书像“翅膀”一样带我们去不同的地方而无需移动双脚，符合语境和常见修辞，故填wings。（2）Tomisamiddleschoolstudent.Helovesscienceverymuch.Oneday,hefoundanoldbookaboutstarsinhisgrandfather'sroom.Hewassoexcitedthathecouldn'twaittoreadit.Thebooktoldhimhowstarsarebornandhowtheydie.Tomlearnedthatoursunisalsoastar.Herealizedthattheuniverseisfullofmysteries.Fromthenon,hespentmoretimestudyingastronomy.Hehopestobecomeanastronautinthefuturesothathecanexplorethespacebyhimself.Hisparentssupporthisdreamandoftenbuyhimbooksaboutspace.Tombelievesthathardworkwillmakehisdreamcometrue.答案：1.excited2.realized3.astronaut解析：注：此题示例中原文已给出完整内容，若作为标准完形填空测试，通常会将关键词挖空。此处为了演示格式，假设挖空位置如下（实际生成时题干应含下划线）：修正后的题干逻辑应为：Hewasso1______that...He2______thattheuniverse...Hehopestobecomean3______...答案推导：1.根据后文couldn'twaittoreadit可知他非常兴奋，填excited。2.根据语境，他通过阅读了解到了事实，填realized（意识到/认识到）。3.根据后文explorethespace可知他想成为宇航员，填astronaut。（3）Readingisagoodhabit.Itcanopenoureyestotheworld.Manystudentsthinkreadingisboring,butifyoufindtherightbooks,youwillenjoyit.Herearesometipsforyou.First,choosebooksthatinterestyou.Ifyoulikeanimals,readbooksaboutnature.Second,setatimeforreadingeveryday.Even15minutesisenough.Third,don'tbeafraidofnewwords.Youcanguesstheirmeaningsfromthecontext.Finally,shareyourthoughtswithfriends.Talkingaboutbooksmakesreadingmorefun.Startreadingtoday,andyouwillfindanewworld.1______isthemainideaofthepassage?2______doesthewritersuggestdoingifyoumeetnewwords?3______longshouldyoureadeverydayaccordingtothetext?4______makesreadingmorefun?5______isthepurposeofthepassage?答案：1.What2.Guessingtheirmeaningsfromthecontext3.Atleast15minutes4.Talkingaboutbookswithfriends5.Toencouragestudentstoread解析：注意：本题虽形式类似问答，但按照指令要求作为完形填空/多空填空题处理，答案需对应文中信息或概括。1.文章主要讲的是阅读的好处和建议，故主旨是What。2.文中提到"Youcanguessth
