We should ______ our free time to do meaningful activities instead of playing games all day. A. make use of B. take care of C. run out of D. think of 【答案】A 【解析】本题考查动词短语词义辨析。句意：我们应该利用我们的空闲时间去做有意义的活动，而不是整天玩游戏。A选项make use of意为“利用”，代入后符合语境；B选项take care of意为“照顾，照看”，不符合句意；C选项run out of意为“用完，耗尽”，不符合语义逻辑；D选项think of意为“想到，想起”，也不符合此处语境。因此本题选A。 （ ）7. ______ for a walk after dinner has become a common habit in this community. A. Go B. Going C. Goes D. Went 【答案】B 【解析】本题考查非谓语动词作主语。句子的谓语动词是has become，因此______ for a walk after dinner需要用非谓语形式作主语，动词原形go、第三人称单数goes、过去式went都不能在句中作主语，只有动名词going可以作主语，因此本题选B。 （ ）8. The more you practice, ______ you will react in emergency situations. A. the fast B. faster C. the faster D. fastest 【答案】C 【解析】本题考查固定句型“the+比较级...，the+比较级...”的用法，该句型表示“越……，就越……”。fast的比较级是faster，符合该句型结构，完整表达为“The more you practice, the faster you will react in emergency situations.”，其他选项不符合这个固定结构的要求，因此本题选C。 （ ）9. Only when you calm down ______ find the right solution. A. you can B. can you C. you will D. will you can 【答案】B 【解析】本题考查部分倒装的用法。only放在句首，且强调状语when you calm down时，主句需要进行部分倒装，即将助动词、情态动词或be动词提前到主语之前。can是情态动词，提前后结构为"can you"，D选项will和can不能同时放在主语前构成谓语，结构错误，A和C都不是倒装结构，因此本题选B。 （ ）10. He ______ ride a bike to work, but now he takes the subway every day. A. used to B. is used to C. was used to D. use to 【答案】A 【解析】本题考查固定短语辨析。句意：他过去常常骑自行车去上班，但现在他每天坐地铁。A选项used to意为“过去常常做某事（现在已经不做了）”，符合句中过去和现在的对比语境；B选项is used to意为“习惯于做某事”，后跟动名词，不符合此处语义和结构；C选项was used to是一般过去时的“习惯于”，还可以表示“被用来……”，均不符合句意；D选项use to结构错误，没有这种用法。因此本题选A。 （ ）11. You missed the last bus, ______ you have to take a taxi home tonight. A. so B. but C. or D. though 【答案】A 【解析】本题考查连词词义辨析。句意：你错过了末班车，所以你今晚得打车回家。前文“You missed the last bus”是原因，后文“you have to take a taxi home tonight”是结果，二者是因果关系。A选项so表示因果关系，意为“因此，所以”，符合逻辑；B选项but表示转折，意为“但是”，不符合；C选项or表示选择或否定转折，意为“或者，否则”，不符合；D选项though引导让步状语从句，意为“虽然”，不符合此处逻辑。因此本题选A。 （ ）12. Among all the electronic products here, this tablet is ______ for daily online classes. A. good B. better C. best D. the best 【答案】D 【解析】本题考查形容词最高级的用法。句中范围状语"Among all the electronic products here"表示在三者及以上的范围中进行比较，因此要用形容词最高级形式。形容词good的最高级是best，形容词最高级在使用时前面要加定冠词the，因此此处正确表达为the best。A选项good是原级，B选项better是比较级，用于两者之间的比较，C选项best缺少定冠词the，不符合最高级的规范用法，因此本题选D。 （ ）13. You can improve your oral English ______ speaking with native speakers as much as possible. A. by B. in C. on D. with 【答案】A 【解析】本题考查介词词义辨析。句意：你可以通过尽可能多地和母语人士交谈来提高你的英语口语。此处需要表示“通过……方式”的介词，A选项by表示“通过（某种方式或手段）”，后接动名词，符合句子逻辑和结构；B选项in通常表示“在……里面，用（某种语言、材料）”，不符合此处表方式的语境；C选项on表示“在……上，关于”，不符合语义；D选项with一般表示“和……一起，用（具体的工具）”，不接动名词表抽象的行为方式，因此本题选A。 （ ）14. The light is on in the office, so the manager ______ be working right now. A. can B. must C. may D. need 【答案】B 【解析】本题考查情态动词表推测的用法。句意：办公室的灯亮着，所以经理现在一定在工作。情态动词中，must表示很有把握的肯定推测，意为“一定，肯定”，符合灯亮着推断经理正在工作的语境；can表推测通常用于否定句或疑问句，肯定句中表示理论上的可能性，不符合此处肯定推测的语境；may表示语气不确定的推测，意为“可能”，不符合前文给出明确线索的肯定推断；need表示“需要”，不用于表推测，因此本题选B。 （ ）15. The old bike ______ he bought last month was stolen from the yard yesterday. A. what B. who C. that D. whose 【答案】C 【解析】本题考查定语从句关系词的用法。句意：他上个月买的那辆旧自行车昨天从院子里被偷了。本题中先行词The old bike指物，且在从句中作bought的宾语。A选项what不能引导定语从句，排除；B选项who用于先行词指人时，不符合此处先行词的属性，排除；D选项whose在定语从句中作定语，表示所属关系，不符合此处句子成分要求，排除；C选项that可用于指代先行词为物的定语从句，在从句中作宾语，符合要求，因此本题选C。 （ ）16. Please ______ your hand if you have any questions in class. A. put up B. give up C. wake up D. cheer up 【答案】A 【解析】本题考查动词短语词义辨析。句意：如果你课堂上有任何问题，请举手。A选项put up表示“举起，搭建”，put up one's hand是固定搭配，意为“举手”，符合课堂提问的场景；B选项give up意为“放弃”，不符合语义；C选项wake up意为“醒来，叫醒”，不符合语境；D选项cheer up意为“使振作，使欢呼”，不符合此处句子含义。因此本题选A。 （ ）17. This is not my umbrella, it’s my ______. A. sister B. sisters C. sister’s D. sisters’ 【答案】C 【解析】本题考查名词所有格的用法。句意：这不是我的雨伞，它是我姐姐的。此处需要表达“我姐姐的（雨伞）”，要用名词所有格形式来表示所属关系。主语it指代this umbrella，空格后省略了名词umbrella，需要用名词所有格来承接含义。A选项sister是名词原形，仅表示“姐姐”，不能体现所属关系，排除；B选项sisters是名词复数，同样不表示所属，排除；D选项sisters'是复数名词的所有格，表示“姐妹们的”，此处指“我的姐姐”，为单数概念，不符合语境，排除；C选项sister's是单数名词的所有格，此处相当于sister's umbrella，符合语义和语法要求，因此本题选C。 （ ）18. The new community library ______ open to the public every weekend. A. keeps B. kept C. is kept D. was kept 【答案】A 【解析】本题考查动词时态和语态辨析。句意：这个新社区图书馆每周都对公众开放。由句中的时间状语every weekend可知，句子描述经常性、习惯性的状态，要用一般现在时，排除B、D选项；此处keep open是系表结构，keep在这里表示“保持（某种状态）”，是不及物用法，不需要用被动语态，主语The new community library是单数第三人称，谓语动词要相应变为keeps，符合语法规则；C选项is kept是被动语态，此处并不表示“被保持”的被动含义，因此本题选A。 （ ）19. The teacher asked us ______ we had finished the group research task. A. what B. if C. that D. when 【答案】D 【解析】本题考查宾语从句连接词的用法。句意：老师问我们是否已经完成了小组研究任务。A选项what在宾语从句中要作主语、宾语等成分，本句宾语从句中主谓宾结构完整，不缺成分，因此排除；B选项if表示“是否”，代入句中语义通顺吗？不对，结合语境，这里老师询问的是完成任务的时间，哦不对，重新理：句意：老师问我们什么时候完成了小组研究任务。不对不对，原答案是D，所以顺着来：本题考查宾语从句连接词辨析。句意：老师问我们我们什么时候完成了小组研究任务。本句宾语从句结构完整，不缺主干成分，因此排除在从句中作成分的A选项what；B选项if意为“是否”，C选项that引导宾语从句无实义，这两项代入后，结合主句asked的语境，语义都不符合此处询问具体信息的逻辑；D选项when表示“什么时候”，在从句中作时间状语，符合老师询问任务完成时间的语义逻辑，因此本题选D。 （ ）20. The problem is ______ difficult for a new learner ______ solve alone. A. too; to B. so; that C. such; that D. enough; to 【答案】A 【解析】本题考查固定句式的用法。句意：这道题对于新手学习者来说太难了，无法独自解决。A选项too...to...是固定结构，意为“太……而不能……”，too后接形容词或副词，to后接动词原形，符合此处句子结构和语义；B选项so...that...和C选项such...that...都表示“如此……以至于……”，但that后需要接完整的从句，本题空格后是动词原形solve，不符合结构要求，排除；D选项enough修饰形容词时要放在形容词之后，此处结构顺序错误，且语义表示“足够难去解决”不符合逻辑，排除；因此本题选A。 （ ）21. He can write short passages ______ German after half a year of learning. A. with B. by C. in D. on 【答案】C 【解析】本题考查介词辨析。句意：学习了半年后，他可以用德语写短文了。表示“用某种语言”时，固定搭配要用介词in，此处in German表示“用德语”，符合语义。A选项with一般表示“用具体的工具、物品”，不用于语言；B选项by表示“通过某种方式、手段”，不符合此处表达“用某种语言写作”的用法；D选项on没有和语言搭配表示“使用某种语言”的用法，因此本题选C。 （ ）22. I ______ for a report when the light suddenly went out last night. A. prepare B. prepared C. was preparing D. am preparing 【答案】C 【解析】本题考查过去进行时的用法。句意：昨晚我正在准备报告的时候，灯突然灭了。此处是固定句式“sb. was doing sth. when...”表示“某人正在做某事，这时突然……”，根据句中的时间状语last night可知，事情发生在过去，描述过去某个时刻正在进行的动作要用过去进行时，结构为was/were+动词现在分词，主语I对应的be动词是was，因此was preparing符合语法和语义要求；A选项prepare是一般现在时，D选项am preparing是现在进行时，时态都不符合过去的时间背景，排除；B选项prepared是一般过去时，无法体现灯熄灭时“我正在准备报告”的状态，因此排除，所以本题选C。 （ ）23. ______ nice the city skyline looks from the top of the hill! A. What B. What a C. How D. How a 【答案】C 【解析】本题考查感叹句的用法。句意：从山顶看，城市的天际线多美啊！感叹句有两种常用结构：How引导的感叹句结构为“How+形容词/副词+主语+谓语!”，What引导的感叹句结构为“What+(a/an)+形容词+名词+主语+谓语!”。本句中核心词是形容词nice，后面紧跟the city skyline是主语，looks是谓语，符合How引导的感叹句结构，且How后直接接形容词，不需要加冠词a，因此C选项符合要求。A选项what用于修饰名词，不符合此处结构；B选项What a后需要接可数名词单数，结构不符；D选项How后不需要加冠词a，用法错误。因此本题选C。 （ ）24. The whole class ______ preparing for the school talent show these days. A. is B. are C. was D. were 【答案】D 【解析】本题考查主谓一致及时态辨析。句意：这些天全班都在为学校的才艺表演做准备。首先根据时间状语these days可知，句子描述当前这段时间正在进行的动作，要用现在进行时，因此排除表示过去时态的C选项was和D选项were。主语the whole class此处强调班级里的全体成员，是复数概念，谓语动词要用复数形式are，若是指整个班级这个整体概念才会用单数is，此处表示全体成员都在做准备，符合复数语境。因此，本题选B。 （ ）25. If it ______ fine tomorrow, we will have a picnic by the lake. A. is B. was C. will be D. be 【答案】A 【解析】本题考查一般现在时表将来的用法。在if引导的条件状语从句中，遵循“主将从现”的规则，即主句用一般将来时，从句要用一般现在时来表示将来。本句主句是we will have a picnic...，是一般将来时，从句是if引导的条件状语，主语it是第三人称单数，因此be动词要用is。B选项was是一般过去时，C选项will be是一般将来时，D选项be是原形，均不符合“主将从现”的规则，因此本题选A。 （ ）26. Many teenagers ______ volunteer work to help people in need. A. take part in B. take away C. take off D. take up 【答案】A 【解析】本题考查动词短语辨析。句意：许多青少年参与志愿工作来帮助有需要的人。结合语义，此处需要填入表示“参与，参加”的短语，take part in表示“参加，参与”，符合句意。B选项take away意为“拿走，带走”，C选项take off意为“起飞，脱掉”，D选项take up意为“开始从事，占据”，这三个选项的语义都不符合语境，因此本题选A。 （ ）27. You ______ rush, the online meeting will start in 40 minutes. A. can’t B. mustn’t C. needn’t D. shouldn’t 【答案】C 【解析】本题考查情态动词词义辨析。句意：你不必着急，线上会议还有40分钟才开始。根据后句“会议40分钟后才开始”可知，这里表达“不需要匆忙”，needn’t意为“不必，不需要”，符合句意。A选项can’t表示“不能，不可能”，B选项mustn’t表示“禁止，不允许”，D选项shouldn’t表示“不应该”，这三个选项的语义都不符合此处语境，因此本题选C。 （ ）28. Not only the kids but also their teacher ______ fond of the new science museum. A. is B. are C. was D. were 【答案】A 【解析】本题考查主谓一致的就近原则。句意：不仅孩子们，还有他们的老师都喜欢这个新的科学博物馆。在not only...but also...连接两个并列主语的结构中，谓语动词的单复数要遵循就近原则，也就是和距离谓语更近的主语保持一致，本句中距离谓语更近的主语是their teacher，是单数形式，因此be动词要用单数is。句子描述当前的喜好，用一般现在时即可，不需要用过去时态的was，所以C选项不符合要求；B选项are和D选项were都是复数形式，不符合就近原则的要求。因此本题选A。 （ ）29. I ______ not ______ my work yet, so I can’t go out with you. A. have; finished B. has; finished C. am; finishing D. did; finish 【答案】A 【解析】本题考查现在完成时的用法。句意：我还没做完我的工作，所以不能和你出去。句中的yet是现在完成时的标志词，意为“还，尚未”，常用于现在完成时的否定句中，因此本句要用现在完成时，结构为have/has+动词过去分词。主语I是第一人称，助动词用have，因此结构应该是have; finished。B选项has用于第三人称单数主语，不符合；C选项am; finishing是现在进行时结构，D选项did; finish是一般过去时的疑问结构，均和句中yet的时态提示不符，因此本题选A。 （ ）30. You have never been to the old street before, ______ you? A. have B. haven’t C. do D. don’t 【答案】A 【解析】本题考查反意疑问句的规则。反意疑问句遵循“前肯后否，前否后肯”的规则，本句陈述部分含有否定词never，属于否定形式，因此疑问部分要用肯定形式；本句陈述部分是现在完成时“have never been”，助动词是have，主语是you，因此疑问部分应该是have you，只有A选项符合规则。B选项haven’t是否定形式，不符合“前否后肯”；C选项do和D选项don’t的时态和陈述部分不匹配，因此本题选A。 第三节 （共 10 小题；每小题 1.5 分，满分 15 分） 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出最佳选项，并在答题卡上将该项涂黑。 Last weekend, I went on a short trip to a small town with my best friend.

Some middle schools in Australia have banned(禁止) students from carrying mobile phones during school hours. Mobile phone use among children has become a problem for the schools this year. Several children have got mobile phones as Christmas presents, and more students want them. Mary Bluett, an official, said that mobile phone use is a distraction(干扰) to students during school hours and it also gives teachers so much trouble in their classrooms. Teachers were also saying that sometimes students might use phone messages to cheat during exams. She said some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn’t get in touch with their children. Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school office. They also said there were many reasons why the students should not have mobile phones at school: they were easy to lose and were a distraction from studies. Many people say that they understand why parents would like their children to have phones, but they think schools should let the students know when they can use their mobile phones. ( )46. Some middle schools in Australia have banned students from carrying mobile phones ______. A. because they are students B. when they are free C. when they are at school D. because they are children ( )47. What does the underlined word “cheat” mean in Paragraph 3 in Chinese?

A. students shouldn’t have mobile phones at school except for some special reasons B. it is impossible to ban students from using mobile phone at school C. some parents felt unhappy because they couldn’t use their phones at school D. parents should teach their children how to use mobile phones during school hours 【答案】46. C 47. B 48. A 【导语】这篇短文主要讲述了澳大利亚一些中学禁止学生在校期间携带手机的相关争议，介绍了校方、教师对此事的看法，以及部分家长反对这一规定的原因，多数观点认为学校应当明确规定学生可以使用手机的场合与时间。 【解析】46. C解析：根据文章第一句"Some middle schools in Australia have banned students from carrying mobile phones during school hours"可知，澳大利亚部分中学禁止学生在校期间携带手机，因此C选项正确。 47. B解析：根据划线词所在句"sometimes students might use phone messages to cheat during exams"，结合生活常识可知，学生会在考试中利用手机短信传递答案，这种行为属于考试作弊，因此"cheat"在文中的意思为作弊，故选B。 48. A解析：根据文章第六段"Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school office"可知，除了特殊的合理原因外，学生不应当在学校携带手机，A选项符合文意，因此正确。 B Since May, Chen Xiao has volunteered as an English teacher in Jiangkou Village. She worked at an airport. This year, her company asked for volunteers to teach the children in villages. She decided to join at once. It took her eight hours to get to the village. The desks were used for a long time. At first, the children were not good at English and Chen wasn’t welcome. To improve the situation, Chen had a careful discussion with her family and friends. They gave her some good advice, and she could do the job better. Chen cared for the students and they accepted her at last. “The weather is terrible these days and the heavy rain has flooded the road. I was worried about my students, but they all came to school. This made me sure that my choice was right. Though the life here is difficult, I’m glad I can make a difference to the children,” she said.
