A．neither has Mary B．so has Mary C．neither does Mary D．so does Mary 【答案】D 【详解】考查部分倒装。句意：Catherine是一个非常勇敢的女孩。她总是在课堂上问问题，玛丽也一样。当前一句是否定句时，表示后者情况与前者一样，需用neither引导的倒装句，其构成为：neither+助动词/情态动词/be动词+主语；若前一句是肯定句时，表示后者情况与前者一样，需用so引导的倒装句，其构成为：so +助动词/情态动词/be动词+主语；由“She always asks questions in class”可知，前一句是肯定句，所以空处需用so引导的倒装句；由前一句谓语动词asks可知，空处谓语动词需用一般现在现在时，主语是Mary，助动词需用does，表示“问问题”。故选D。 34．Though a man may also feel like screaming as a woman________ in a crisis, he has a little bit more self-control than a woman and that makes the difference. A．having B．has C．doing D．does 【答案】D 【详解】考查实义动词。句意：虽然男人在危机中也会像女人一样尖叫，但比女人更有自制力，这一点很重要。在从句as a woman________ in a crisis中缺少谓语，故排除A、C。do代替上文提到的动词feel like，而B项意为“有”，作为助动词不能替代上文提的的动词。故D项正确。 【点睛】do、does、did即可做助动词，也可做实义动词。如例句What does he do every day? 中，does是助动词，后面的do是实义动词！ 35．—Would you please repeat your telephone number? I __________ quite catch it. —It’s 62548239. A．can’t B．couldn’t C．didn’t D．don’t 【答案】C 【详解】考查助动词和时态。句意：——请你重复一下你的电话号码好吗？我没听清。——是62548239。由前句“请你重复一下你的电话号码好吗？”可知，此处缺乏相应的否定助动词， catch这个动作发生在过去，所以用didn’t。故选C项。 36．Mary likes communicating with many people when she is traveling outside; ________. A．so her mother does B．so her mother is C．so does her mother D．so is her mother 【答案】C 【详解】考查倒装。句意：Mary喜欢外出旅行时与许多人交流，她的妈妈也是。so+助动词/连系动词+主语表示另一主语和前面所陈述的情况有相同的肯定概念，意为“也一样、也是如此”，根据likes判断此处用does，故C项正确。 37．As your spoken English gets better, so ______ your written English. A．does B．is C．has D．will 【答案】D 【详解】考查助动词。句意：随着你英语口语的好转，你的书面语也会好起来的。so+助动词/情态动词/be动词+主语，表示后者和前者一样，遵循主将从现的原则，助动词应该用will，故D项正确。 38．—Mr. Smith must know a lot about Chinese history. —_______. He has studied it for years. A．So he does B．So does he C．So he must D．So must he 【答案】A 【详解】考查固定句型。句意：——史密斯先生一定很了解中国历史。——的确如此。他已经学了很多年了。so sb. do的意思是“的确如此”，一般表示赞同某人某事；so do sb.的意思是“谁谁谁也是这样的”，一般表示和某人、某事的情况一样；so he must 的意思是“因此他必须怎样怎样”，一般表示某人不得已必须要干某事；Yes，he must的意思是“是的，他必须这么做”，一般用再赞同某人的看法上。根据后文“He has studied it for years.”可知此处指“的确如此”，故选A。 39．—Why not buy the beautiful necklace since you like it so much? —I would but I _____ have enough money.

A．are B．have C．do D．will 【答案】C 【详解】考查助动词和省略句。句意：你花了比学习更多的时间来打网络游戏简直就是疯了。than 前后动词形式要一致，前面是you spend，所以后边用you do代替you spend，避免重复。故选C。 41．The percentage of students at high schools who ________ newly diagnosed with depression  ________not dropped significantly. A．was; has B．were; has C．was; have D．were; have 【答案】B 【详解】考查主谓一致。句意：最近被诊断患有抑郁症的高中生的比例还没有显著下降。第一空为定语从句中谓语动词被动态；定语从句谓语动词的形式由先行词单复数决定，先行词students at high schools是复数形式，故be动词用复数，且动作发生在过去，用一般过去时复数形式were；第二空为主句谓语动词现在完成时助动词have的选择，主语the percentage是单数，故助动词用三单形式has。故选B项。 42．Sally’s never seen a play in the Shanghai Grand Theatre, ________?

Seldom________ what they should do in return. A．do they think B．they think C．did they think D．think they 【答案】A 【详解】考查部分倒装句结构。句意：当今社会，许多青少年把父母对他们的爱当成是理所当然。他们几乎都没有考虑过应该做什么去回报父母。Seldom是否定副词“几乎不”的意思，放在句首时，主句谓语要部分倒装，即把谓语里面的助动词、情态动词或be动词提到主语前面。根据句意，这句话应该是一般现在时，谓语是实义动词think，主语是复数代词they，所以倒装时要加助动词do，并将其提到主语的前面，所以应该填do they think。故选A项。 44．The boy spent as much time watching TV as he _______ studying. A．does B．had C．was D．did 【答案】D 【详解】考查比较状语从句和助动词。句意：这个男孩看电视的时间和学习的时间一样多。本句为as…as引导的比较状语从句，he _____ studying为状语从句部分，根据spent可知，从句用一般过去时，空处缺少动词spent，可以用助动词来代替，此处用助动词did。故选D。 45．Mr.White doesn’t believe that his son could afford to buy a digital camera，________？ A．could he B．couldn’t he C．does he D．doesn’t he 【答案】C 【详解】考查反意疑问句。怀特先生不相信他的儿子能买得起一台数码照相机，对吗？根据句子结构可知，这句话考查反意疑问句。句子陈述部分是宾语从句，反意疑问句部分要依据主句的主语和谓语动词的结构来判断。主句谓语是实义动词“believe”，反意疑问句部分要用到助动词do。又因为陈述句主句的主语是第三人称“Mr.White”，而且是一般现在时的否定句，有助动词does，所以，反意疑问句部分要用助动词的肯定形式+主语的结构。故选C项。 ( 9 )原创精品资源学科网独家享有版权，侵权必究！学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
