参考答案及解析1.【参考答案】A【解析】主语"thenumberof"表示"……的数量"，谓语动词用单数形式。句中有"theseyears"表明是现在进行时态，故用isincreasing。are用于复数主语，was/were是过去时态，不符合语境。2.【参考答案】B【解析】主句"Sheasked"是过去时，从句动作发生在asked之前，即过去的过去，应用过去完成时had+过去分词。beento表示"去过某地并已回来"，goneto表示"去了某地还没回来"，根据句意应用beento，故选B。3.【参考答案】B【解析】"notuntil"置于句首时，主句要使用部分倒装结构，即将助动词、情态动词或be动词提到主语前面。本句是一般过去时，故用didIfeel。正常语序为Ididnotfeelsorryforbeinglateuntilthemeetingstarted.4.【参考答案】B【解析】这是强调句型"Itwas+被强调部分+that+其他部分"。本句强调的是地点状语"inthesupermarket"，故用that连接。如果去掉"Itwas"和"that"，剩余部分仍能构成完整句子，说明这是强调句而非定语从句。5.【参考答案】A【解析】"aswellas"连接两个主语时，谓语动词的单复数由前面的主语决定。本句主语是"Theteacher"，为单数，排除B、C、D。根据"tomorrow"判断用一般将来时begoingto结构，故选A。6.【参考答案】B【解析】"wouldrather+主语+谓语"句型中，如果从句主语与主句不同，从句谓语动词要用虚拟语气，即过去式表示对将来的虚拟。本句中主句是"I"，从句是"you"，主语不同，故用called。7.【参考答案】B【解析】主语"thenewtheory"与动词"discuss"之间是被动关系，且时间状语是"lastweek"，故用一般过去时的被动语态was/were+过去分词。A是现在完成时的主动语态，C是一般现在时的被动语态，D是主动语态，均不符合要求。8.【参考答案】A【解析】"thereisnodoubtthat..."是固定句型，意为"毫无疑问……"。that引导同位语从句，解释doubt的具体内容。whether和if引导从句时表示"是否"，常用于有doubt的否定句中；what引导名词性从句时在从句中作成分，不符合题意。9.【参考答案】A【解析】"Thereasonwhy...wasthat..."是固定句型，意为"……的原因是……"。that引导表语从句，在从句中不充当成分，只起连接作用。because引导原因状语从句，不与thereason搭配作表语；whether表示"是否"；what在从句中需充当主语或宾语。10.【参考答案】D【解析】notas/so...as...是同级比较的否定形式，中间用原级。此处修饰动词speaks，应用副词fluently而非形容词fluent，故排除A、B。C选项缺少第一个as，结构不完整。因此选D，意为"当然不如母语者说得流利"。11.【参考答案】B【解析】"regrettodosth."表示"遗憾地要做某事"，常用于告知坏消息；"regretdoingsth."表示"后悔做过某事"。本句是正式告知申请人申请未被接受，应用regrettotell。A表示后悔已经告诉过，C、D语法结构不对。12.【参考答案】B【解析】"theearth'senvironment"意为"地球的环境"。litter指垃圾，pollution指污染，waste指废物。句意是"我们应该尽一切努力防止地球环境受到污染"，prevent...frombeingpolluted是固定搭配。environment最符合语境。13.【参考答案】A【解析】"advisesb.(not)todosth."是固定搭配，但本题考查的是"advisesb.nottodosth."的否定形式。根据句意"医生建议我祖父少抽烟以保持健康"，应该是否定含义，即advisedmygrandfathernottosmoke。但选项中只有smoke，结合语境应是lesssmoke的省略结构，选A。14.【参考答案】B【解析】"Itishightimethat..."句型中，从句谓语动词要用过去式，表示"是时候做某事了"。这是一种虚拟语气用法，与事实相反或表示紧迫性。本句中没有could/would等词时只能用过去式，故选took。15.【参考答案】A【解析】"beabouttodosth.when..."是固定句型，意为"正要……这时……"。when在此引导突发性事件，表示"就在……的时候"。then是副词不能引导从句；while引导持续性动作；as表示"随着"或"当……时"，不符合此句型结构。16.【参考答案】A【解析】定语从句中先行词是"thewoman"，从句中"bag"与先行词之间是所属关系，即"那位女士的包"，应用whose引导定语从句。who在从句中作主语；which用于指物；whom在从句中作宾语，均不符合语法要求。17.【参考答案】B【解析】反义疑问句遵循"前肯后否，前否后肯"的原则。主句是"Idon'tthink+宾语从句"，否定转移，疑问部分应与宾语从句保持一致。宾语从句"dIDhedo"中dID是助动词，且句中有yesterday表示过去时，故疑问部分用didhe。18.【参考答案】C【解析】定语从句中先行词是"theboy"，从句中"parents"与先行词之间是所属关系，即"那个男孩的父母"，应用whose引导定语从句。who在从句中作主语；whom在从句中作宾语；which用于指物，均不符合语法要求。19.【参考答案】C【解析】这是对现在情况的虚拟语气，if条件句用过去式（be动词用were），主句用would/could/should/might+动词原形。本句"IfIwereyou"是固定表达，表示"如果我是你"，与现在事实相反。was仅用于第一、三人称单数的非正式虚拟。20.【参考答案】B【解析】referredtobythemanager是过去分词短语作后置定语，修饰theman。本句缺谓语动词，且根据语境应用一般过去时，turnedouttobe表示"结果证明是……"。turnsout是一般现在时；turningout是非谓语形式；toturnout是不定式，均不符合句子结构要求。21.【参考答案】C【解析】本题考查感叹句。beautiful是形容词，flower是单数可数名词，感叹句结构为What+a+形容词+单数可数名词+主语+谓语。故选C。How+形容词/副词+主语+谓语的结构后不跟名词。22.【参考答案】B【解析】本题考查if引导的条件状语从句，遵循"主将从现"原则，即主句用一般将来时，从句用一般现在时表将来。故选B。23.【参考答案】C【解析】本题考查被动语态。book是write的承受者，且时间状语lastyear表明用一般过去时，故用一般过去时的被动语态was/were+过去分词。故选C。24.【参考答案】A【解析】本题考查现在完成时的时间状语。since+时间点，表示"自从……以来"，与现在完成时连用。for+时间段。此处hewasachild是时间点，故选A。25.【参考答案】B【解析】本题考查动词辨析。suit指颜色、款式等适合某人；fit指尺寸、大小合适；match指颜色、图案相配。此处指款式适合，故选B。26.【参考答案】A【解析】本题考查"the+比较级，the+比较级"结构，表示"越……就越……"。better是good/well的比较级。故选A。27.【参考答案】B【解析】本题考查neither...nor...的谓语动词一致原则及一般过去时。谓语动词与最近的主语hissister一致，用单数；yesterday表明用一般过去时。故选B。28.【参考答案】A【解析】本题考查asksb.nottodosth.结构，否定形式在不定式符号to前加not。故选A。29.【参考答案】B【解析】本题考查句子成分分析。met是及物动词，其后anoldfriendofmine作宾语。故选B。30.【参考答案】B【解析】本题考查过去完成时。bythetime引导的时间状语从句用一般过去时，主句动作发生在从句之前，用过去完成时had+过去分词。故选B。31.【参考答案】B【解析】本题考查交际用语。对方提出建议，表示赞同应用Thatsoundsgreat（听起来不错）。A项"你是对的"；C项"祝你玩得开心"；D项"没关系"。故选B。32.【参考答案】C【解析】本题考查Itis+adj.+todosth.句型，it作形式主语，真正的主语是不定式。故选C。33.【参考答案】A【解析】本题考查主谓一致。thenumberof意为"……的数量"，作主语时谓语动词用单数。anumberof意为"许多"，谓语动词用复数。故选A。34.【参考答案】B【解析】本题考查间接引语中时态的变化。主句said是过去时，从句应用相应的过去时态，willgo变为wouldgo。故选B。35.【参考答案】D【解析】本题考查定语从句。先行词是thegirl，在从句中作talked的宾语，应用whom引导。who作主语；which修饰物；whose表所属关系。故选D。36.【参考答案】A【解析】本题考查现在完成时。for+时间段与现在完成时连用，表示动作从过去持续到现在。故选A。37.【参考答案】A【解析】本题考查倍数表达法。倍数+as+形容词原级+as是正确结构。故选A。38.【参考答案】A【解析】本题考查交际用语。Wouldyouminddoingsth.?的回答：Notatall./Nevermind./Ofcoursenot.都表示"不介意"。Yes,please不符合语境。故选A。39.【参考答案】C【解析】本题考查定语从句。先行词是Thestory，指物，在从句中作read的宾语，应用that或which引导。故选C。40.【参考答案】A【解析】本题考查连词辨析。sothat引导目的状语从句，表示"以便、目的是"；because表原因；though表让步；unless表条件"除非"。此处表目的，故选A。41.【参考答案】C【解析】本题考查定语从句的关系词。先行词是物"thebook"，在从句中作宾语，应用关系代词which或that引导定语从句。who/whom用于指人，what不能引导定语从句。故选C。42.【参考答案】B【解析】本题考查一般将来时。时间状语"tomorrowevening"表示将来时间，应使用一般将来时willdo结构。故选B。43.【参考答案】B【解析】本题考查时间介词的用法。since后接时间点，for后接时间段。"twohours"是时间段，应用for。句意为"我一直在等你两个小时了"。故选B。44.【参考答案】A【解析】本题考查代词的用法。than后需要代词指代前面提到的"theweather"，避免重复。that指代前面提到的同类事物中的一个，可代替不可数名词或单数名词。这里that代替theweather。故选A。45.【参考答案】B【解析】本题考查副词的用法。as...as中间加形容词或副词原级。此处修饰动词speaks，应用副词well。good是形容词，better是比较级，best是最高级。故选B。46.【参考答案】A【解析】本题考查if引导的条件状语从句。if条件从句用一般现在时表将来，主句用一般将来时。即"主将从现"原则。故选A。47.【参考答案】C【解析】本题考查ask的用法。asksb.nottodosth.意为"要求某人不要做某事"。否定不定式在to前面加not。故选C。48.【参考答案】B【解析】本题考查过去完成时。"Bytheendoflastyear"表示在过去某个时间之前已完成的动作，应用过去完成时haddone。故选B。49.【参考答案】B【解析】本题考查日常交际用语。邀请别人去电影院，回答应礼貌得体。B项"我很想去，但我很忙"是委婉拒绝的正确表达。其他选项不符合交际习惯。故选B。50.【参考答案】A【解析】主谓一致题。thenumberof意为"……的数量"，作主语时谓语动词用单数形式；anumberof意为"许多"，后接复数名词，谓语动词用复数。故选A。51.【参考答案】A【解析】本题考查固定搭配。beinterestedin意为"对……感兴趣"，begoodat意为"擅长……"。句意为"他对音乐感兴趣，并且擅长弹钢琴"。故选A。52.【参考答案】A【解析】本题考查定语从句中关系副词的识别。where是关系副词，在定语从句中作地点状语，修饰先行词thehouse。who、which、that均为关系代词。故选A。53.【参考答案】B【解析】本题考查remember的用法。rememberdoingsth.意为"记得做过某事"，remembertodosth.意为"记得要去做某事"。根据句意"我记得离开家之前锁过门"，表示已经做过，应用rememberdoing。故选B。54.【参考答案】B【解析】本题考查notonly倒装句。notonly放在句首时，后面句子需要部分倒装，即把助动词、情态动词或be动词提到主语前面。本句描述现在的情况，用一般现在时。故选B。55.【参考答案】A【解析】本题考查定语从句的关系代词。先行词是movie（物），在从句中作saw的宾语，应用that或which引导。who/whom用于指人，whose表示所有关系。故选A。56.【参考答案】C【解析】本题考查宾语从句的时态。主句是过去时（said），宾语从句需用相应的过去时态。时间状语"thenextweek"表示将来，应用过去将来时woulddo。故选C。57.【参考答案】C【解析】本题考查定语从句的关系代词。先行词是theman，关系代词在从句中作car的定语，表示所属关系，应用whose。whosecar相当于theman'scar。故选C。58.【参考答案】B【解析】本题考查neither...nor的主谓一致。当neither...nor连接两个主语时，谓语动词遵循"就近原则"，即与最近的主语保持一致。students是复数，故用were。故选B。59.【参考答案】A【解析】本题考查现在完成时的用法。时间状语since引导的时间段，主句应用现在完成时have/hasdone。句意为"自从你毕业以来，在这座城市住了多长时间？"故选A。60.【参考答案】C【解析】本题考查worth的用法。beworthdoingsth.是固定搭配，意为"值得做某事"，主动形式表示被动含义。句意为"这本书值得读"。故选C。61.【参考答案】C【解析】表示将来已安排的计划，用现在进行时表将来。"nextweek"提示将来时，begoingto或现在进行时均可表计划。go(一般现在时)不合语境，willgo强调临时决定，havegone表示已去尚未回来。选C。62.【参考答案】B【解析】since引导时间状语从句，主句用现在完成时。book与read是被动关系，故用现在完成时的被动语态hasbeenread。A为主动语态且缺宾语；C为现在进行时；D为过去进行时，均不符合。63.【参考答案】B【解析】if引导虚拟条件句，与现在事实相反时，从句用过去式（be动词一律用were）。句意为"如果我是你"，是对现在的虚拟。64.【参考答案】B【解析】间接引语中，主句asked为过去时，动作"看电影"发生在"asked"之前，即"过去的过去"，应用过去完成时hadseen。A为现在完成时；C为过去将来时；D为一般过去时，均不恰当。65.【参考答案】C【解析】"Itisthefirst/second/thirdtimethat..."句型中，that从句用现在完成时。此处"Itis"为现在时，故用hasbeen。若主句为"Itwas"则从句用hadbeen。66.【参考答案】B【解析】"Themore...,themore..."固定结构，表示"越……就越……"。careful的比较级是morecareful（形容词），carefully是副词。此处作表语，用形容词careful。67.【参考答案】B【解析】"so+adj./adv.+that..."结果状语从句结构。well为副词，修饰动词speaks，用sowell而不用such。such修饰名词，如suchagoodteacher。68.【参考答案】A【解析】主语是"Theteacher"，"togetherwithhisstudents"是插入语，不影响主语单复数。谓语动词随teacher用单数is。若主语改为"Theteachers"则选B。69.【参考答案】B【解析】"notuntil"置于句首时，主句需要部分倒装，将助动词did提前。正常语序为"Wedidnotbegintohavedinneruntil..."，倒装后为"Notuntil...didwebegin"。70.【参考答案】A【解析】定语从句中先行词theboy指人，在从句中作saw的宾语，用whom或who均可，但作宾语时whom更正式。which用于事物；what不能引导定语从句。71.【参考答案】A【解析】wish后接宾语从句，对现在的虚拟用would/could+动词原形。can的过去式是could。句意为"我希望我能飞"。may表示允许；must表示必须，均不合语境。72.【参考答案】B【解析】"bythetime"引导时间状语从句，从句用一般过去时（got），主句用过去完成时had+过去分词。train已经离开，故用left。A项时态应为过去完成时；C、D均错误。73.【参考答案】B【解析】宾语从句中陈述客观真理时，不论主句时态如何，从句用一般现在时。earth为第三人称单数，故用goes。A缺-s；C为过去时；D为非谓语，均错误。74.【参考答案】B【解析】"so+adj.+that..."结果状语从句。difficult为形容词，用so修饰。too...to...结构后接动词原形，不能接句子。such修饰名词。75.【参考答案】B【解析】neither...nor...连接两个主语时，谓语动词遵循"就近原则"，与最近的主语students一致。students为复数，故用are。76.【参考答案】C【解析】"Wouldyouminddoing..."询问对方是否介意，回答"Betternot"意为"最好不要"，表示不同意。Notatall通常回答thanks或sorry；B项语法不通；D项意思矛盾。77.【参考
