May I speak to Laura, please?”及下文“Sorry, shes not at home.”可知，这里是现在进行时，其结构是be doing的形式。主语是she，be动词用is。故选C。九、选择题22B解析：B【详解】试题分析：考查连词辨析。句意: 去看电影很好, 但是我确实只喜欢听音乐。and和, 并且; but但是; so因此; or或者。表示转折, 故选B。23C解析：C【解析】试题分析：句意：妈妈在汤里加了一些盐，但是还是不够咸。A.so，因此，表示结果；B. and，而且，表示递进；C. but，但是表示转折；D. or 或者，否则，表示选择。放了盐，还是不咸，意思转折，故选C。考点：考查连词辨析。24A解析：A【解析】试题分析：根据语境可知此句的含义是对于那些住在上海的人们来说，上海的外貌发生了很大的变化，但是上海的灵魂依然相同。考查连词的用法，表示转折故用but，选择A。考点：考查连词的基本用法25B解析：B【详解】句意：你最好6点半的时候喊醒Tom，否则他比赛就要迟到了。考查连词有用法。 if如果；or或者，否则；and 和，而且；but但是。根据句意可知，表转折，故选B。十、选择题26D解析：D【详解】句意：安，你能告诉我昨天你去哪里了吗？哦，我去我家附近的超市购物。考查宾语从句。分析句子可知，本句是宾语从句，要用陈述语序，排除A；根据“I went to the supermarket for shopping near my home”可知此处询问“去了哪里”，选项D符合。故选D。27D解析：D【详解】句意：我们还没有决定是否要养宠物。考查宾语从句。此句是宾语从句，从句用陈述语序，排除B选项。C选项是一般过去时，主句也要用过去的某种时态，而主句havent decided是现在完成时结构，排除C；由havent decided可知，引导词用whether最合语境。故选D。28D解析：D【详解】句意：你能告诉我什么时候举行毕业生聚会吗？后天。考查宾语从句。when we had the school leavers party一般过去时，陈述语序；when did we have the school leavers party一般过去时，疑问语序；when will we have the school leavers party一般将来时，疑问语序；when we will have the school leavers party一般将来时，陈述语序。根据答语“The day after tomorrow.”可知，空出的句子应用一般将来时，故排除A、B项；根据句意，空出的句子是宾语从句，应用陈述语序，故排除C项。故选D。29B解析：B【详解】句意：杰克明天要举行一个生日聚会。你知道他更喜欢什么礼物吗？我不确定。我们给凯茜打个电话，她可能知道一些情况。考查宾语从句。此句是宾语从句，从句用陈述语序，排除A和C选项。根据“Jack will have a birthday party tomorrow”可知，如果询问派对在哪里举办，要用一般将来时，D选项时态不对，排除D选项，故选B。十一、选择题30C解析：C【详解】句意：“早起的鸟儿有虫吃。”的意思是你要想成功，就不得不比别人早做好准备。考查常识和习语。A miss is as good as a mile失之毫厘，谬之千里；A friend in need is a friend indeed患难朋友才是真朋友；The early bird catches the worm早起的鸟儿有虫吃；When in Rome, do as the Romans do入乡随俗。根据分析，C符合题意，故选C。31B解析：B【详解】句意：我表弟差点被选为主席。很遗憾，一个小小的错误使他失去了这个大好机会。失之毫厘，谬以千里。考查谚语。Every dog has its day人人皆有得意时；A miss is as good as a mile失之毫厘，谬以千里；Never say bad words about others behind永远不要背后说别人的坏话；No pains, no gains一分耕耘，一分收获。根据“a small mistake cost him the great chance”可知ACD三项不合语境，故选B。十二、选择题32B【详解】句意：谢谢你带我参观。不用客气。考查情景交际。Dont worry about the task不要担心这个任务；Thank you for showing me arou解析：B【详解】句意：谢谢你带我参观。不用客气。考查情景交际。Dont worry about the task不要担心这个任务；Thank you for showing me around谢谢你带我参观；Be careful when you travel旅行时要小心；Youd better get up now你最好现在起床。根据“Its a pleasure”可知，此句是一个表达感谢的句子，故选B。十三、选择题33C【详解】句意：我路过花园时看见她正在花园里浇花。A. to water动词不定式；B. water动词原形； C. watering现在分词；D. watered动词过时式。see sb.解析：C【详解】句意：我路过花园时看见她正在花园里浇花。A. to water动词不定式；B. water动词原形； C. watering现在分词；D. watered动词过时式。see sb. do sth.表示看到某人做某事了，强调已经完成的事情，或者表述客观事实。see sb. doing sth表示看到某人正在做某事，强调动词正在进行。结合“when I passed by”这一语境，可知“浇水”这一动词发生在路过花园那一时刻，强调动作正在进行，故答案为C。34D【详解】句意：在一个寒冷的冬夜，当汤姆看到妈妈在等他时，他禁不住留下了眼泪。考查动词固定搭配。keep back阻止；A. wait等待，动词原形；B. waited过去式；C. to wai解析：D【详解】句意：在一个寒冷的冬夜，当汤姆看到妈妈在等他时，他禁不住留下了眼泪。考查动词固定搭配。keep back阻止；A. wait等待，动词原形；B. waited过去式；C. to wait动词不定式；D. waiting动名词。根据When Tom saw his mother _ for him on a cold winter night, he couldnt keep back his tears.可知句意为“在一个寒冷的冬夜，当汤姆看到妈妈在等他时，他禁不住留下了眼泪。”考查固定搭配see sb doing sth.“看到某人正在做某事”，故答案选D。35C【详解】句意：曹文轩的家乡盐都值得一观。考查非谓语动词。to visit 动词不定式；visits 动词第三人称单数；visiting 动名词和现在分词；visited 动词过去式或过去分词解析：C【详解】句意：曹文轩的家乡盐都值得一观。考查非谓语动词。to visit 动词不定式；visits 动词第三人称单数；visiting 动名词和现在分词；visited 动词过去式或过去分词。be worth doing sth. “值得做某事”。故选C。36C【详解】句意：我的弟弟宁愿花时间在图书馆看书，也不愿和朋友在微信上聊天。考查动名词作宾语和固定短语。read阅读，in在里面，reading是read的动名词形式；than比。spend解析：C【详解】句意：我的弟弟宁愿花时间在图书馆看书，也不愿和朋友在微信上聊天。考查动名词作宾语和固定短语。read阅读，in在里面，reading是read的动名词形式；than比。spend time (in) doing sth.花时间做某事，所以第一空应用reading。would rather dothan do宁愿做某事而不愿做某事，所以第二个空应用than。故选C。37C【详解】句意：为了下个月的比赛，萨莉非常努力地练习弹吉他。考查非谓语动词。practice doing sth练习做某事，使用动名词作宾语，故选C。解析：C【详解】句意：为了下个月的比赛，萨莉非常努力地练习弹吉他。考查非谓语动词。practice doing sth练习做某事，使用动名词作宾语，故选C。38B【详解】句意：为什么这名医生不停下来吃午饭呢？ 因为他在手术室忙于挽救一位危重病人。stop to do sth.意为“停下来去做某事”，s
