不，不需要。你可以在晚饭后做。考查情态动词。neednt不需要；mustnt禁止；shouldnt不应该；cant不能。根据英语语法，对于must开头一般疑问句，若要作否定回答，可用neednt，不用mustnt。故选A。2B解析：B【详解】句意：使我高兴的是，我们不必去银行了。玛丽借给了我们一些钱。考查情态动词辨析。shouldnt不应该；neednt不必，不需要；couldnt不可能；wouldnt不会。由“Mary has lent us some money”可知，玛丽已经借给我们钱了，所以我们不必再去银行了。故选B。3C解析：C【详解】句意：快点，杰克！让那个我们尽快地过马路。不，你不能这样，你没有看到是红灯吗？考查情态动词。couldnt不能，不会；wouldnt不愿意；mustnt禁止，不要；neednt不需要，不必。根据下文“Dont you see the light is still red”可知，现在是红灯，禁止过马路，故选C。4D解析：D【详解】句意：高中入学考试快到了! 是的，我们老师告诉我们考试时再怎么仔细都不为过。考查情态动词。mustnt禁止；shouldnt不应该；neednt不必；cant不能。“cant be too +adj.”意为“再怎么样也不为过”，结合语境，故选D。5C解析：C【详解】句意：有人敲门。一定是我妈妈。她总是这个时候回家。考查情态动词辨析。may也许；may not也许不；must一定；cant不能。根据“She always comes back home at this time.”可知，此处表示非常肯定的推测，故选C。6C解析：C【详解】句意：爸爸，我们一定要等绿灯吗？是的，恐怕我们必须这样做。这是交通规则。考查情态动词。may可能；can可以；have to必须；need需要；根据“must we wait until the light becomes green”及“Thats the traffic rule”可知，每个人都必须要遵守交通规则，应用have to，故选C。7A解析：A【详解】句意：锻炼是有帮助的但是它必须是有规律的锻炼。考查情态动词辨析。must一定，必须；may也许；can能够；need需要。根据but转折可知有规律的锻炼才对身体有帮助，故用must表示一定，必须。故选A。8A解析：A【详解】句意：你必须重新写报告，因为根本不允许有拼写错误。考查情态动词。must必须；can能够；may可以；could能够。根据“spelling mistakes are not allowed at all”可知，拼写错误是不被允许的，所以报告必须重写。故选A。9B解析：B【详解】句意：打扰一下，你能告诉我南京锦绣博物馆在哪里吗？沿着这条路走五分钟。你不会错过的。它是一座巨大的建筑。考查情态动词辨析。mustnt不能，表禁止；cant不可能，表否定推测；neednt无需，指没有必要；shouldnt不应该，表建议。根据下文“Its a huge building”，可知不可能错过这么大的一座建筑，ACD三项不合语境，故选B。10D解析：D【详解】句意：当你参观博物馆时，应该注意一些说明，我们最好不违反它们。考查含情态动词的被动语态和情态动词跟动词原形。“some instructions”和“pay attention to”属于被动关系，所以第一个空用“should be paid attention to”结构，所以排除A、B；had better not do/be意为“最好不做某事”；against“反对”，介词，所以第二个空用动词短语be against “反对”。故选D。11B解析：B【详解】句意：今天我必须去上学，是吗？不，你不必。你可以等好点再去。考查情态动词。mustnt禁止，不要；neednt不必，没有必要。must是情态动词，意为“必须”，反意疑问句应用need构成，答语中也应用need。故选B。12C解析：C【详解】句意：如果你给你妈妈买一台扫地机器人，她就不必每天扫地了。考查情态动词辨析。cant不能；mustnt禁止；neednt不需要；shouldnt不应该。根据“If you buy your mum an iRobot floor cleaner”可知，买了扫地机器人，就不需要人工每天扫地了，故选C。13D解析：D【详解】本题考查：情态动词辨析。选项分析：A. must必须，一定。B. should应该；就；可能；将要。C. would 将，将会（will 的过去式）。D. may可以，能够。综合分析前后句， 可知此处填may最合适，完整句意为：Weve discussed every detail of this plan and have got everything ready.我们已经讨论了这个计划的每个细节，一切都准备好了。But still something may go wrong.但仍有可能出错。We still have to be very careful.我们还是要非常小心。正确答案为：D【点睛】would，could，must，might，may，can都可以表示“可能性”：按照可能性的大小可以排序为might、may、could 、can、should、would、must。也就是说，might表示最小的可能性，must则表示达到最大的可能性。如：He might be at home. 他或许在家（但是可能性不大）。He may be at home. 他或许在家（稍有那么一点儿可能）。He must be at home. 他一定在家。此外，它们还表示各自独特的意思：may / might 表示有应承，即“可以”；can / could 表示有能力，即“能够”；should 表示有义务，即“应该”；would 表示有愿望，即“愿意”；must 表示有必要，即“必须”。14C解析：C【详解】句意：在我小的时候，我的父亲会带我去爬山，那离我们家不远。考查情态动词。may可能；must一定；would将要；should应该。本题考查情态动词的用法，由When I was young 可知，when引导的从句为一般过去时，因此主句应为过去的某种时态；再结合句意及选项，可知C选项符合题意，would+动词原形是过去将来时；故答案选C。15B解析：B【详解】句意：今天暑假我们去露营好吗？没有比这更好的了。考查情态动词辨析。should应该；could可以；must必须；may可能。根据Shall we go camping this summer holiday，可知，此空要对上文的建议表达自己的看法。否定词+比较级表示最高级的意思，此句表示“没有比这更好的了”，用could表示一种委婉的说法。故选B。16D解析：D【详解】句意：请不要以那样的方式开车可以么？那不安全。对不起，我不会再那样做了。考查动词。driving开车，动名词/现在分词形式；to drive动词不定式；drive动词原形。情态动词would后面用动词原形，否定词not放在drive前面。故选D。17A解析：A【详解】句意：准备好了吗？我们开始吧，马丁。游泳？我只是不能习惯冬天游泳。考查情态动词。cant不能；neednt不必；mustnt禁止；shouldnt不应该。根据getusedtoitinwinter“习惯冬天游泳”可知，应该是“不能”习惯冬泳，用cant，故答案选A。18A解析：A【详解】句意：钟南山院士曾经说过:“要预防这一疾病的传播，我们多么小心也不为过。”考查情态动词。can能、能够；may可以；must必须；should应该。can的否定式和too或enough 连用表示“多么也不为过”，其他情态动词没有这种用法，故答案选A。19B解析：B【详解】句意：在交通灯变绿之前不要横穿马路。汽车可能撞到你。考查情态动词。need需要；may可能；should应该；must一定。分析句意可知，交通灯变绿之前横穿马路，汽车有可能会撞到你，故此处应用may表推测。故选B。20D解析：D【详解】句意：你最好从现在开始努力学习，否则你考试会不及格的。考查情态动词和连词辨析。had better do sth最好做某事，排除BC。and和；or否则。分析“you will fail the exam”可知，如果不努力就会不及格，or“否则”符合语境，故选D。21C解析：C【详解】句意：今年北京的沙尘暴很严重。是的，我想知道什么时候我们不需要担心我们呼吸的空气。考查情态动词辨析。cant不可能；mustnt禁止；neednt不必；shouldnt不应该。根据“I wonder when we worry about the air we breathe”可知，想知道什么时候不必担心空气质量，故选C。22D解析：D【详解】句意：听！汤姆一定是一边做作业一边听音乐。让我们上楼去提醒他把音乐关掉。考查情态动词用法。should应该；could能够，可表示委婉语气或用于过去时中；would将会，将要；must必须，表示推测时，意为“一定”。由答语中的“turn it off”可知，此句是推测汤姆一定是在边听音乐边做作业，故选D。23A解析：A【详解】句意：妈妈，我必须今天完成所有作业吗？不，你不必，亲爱的。如果你喜欢，你可以明天完成一些。考查情态动词。neednt不必；shouldnt不应该；cant不可能；mustnt禁止。must引导的一般疑问句否定回答为neednt或dont have to，故选A。24D解析：D【详解】句意：我们已经讨论过这个计划的每个细节并且把一切都准备好了。但仍然有可能出错。我们仍然要非常细心。考查情态动词。must必须；should应该；would将；may可能。根据此处表示推测，应该用may表示可能性，故选D。25C解析：C【详解】句意：苏西刚才描述了事故的每一个细节。她的记忆一定完全恢复了。考查情态动词辨析。shall将要；need需要；must必须，一定；could能。根据“Suzy

plan to go abroad”，可知无论怎样注意保护自己都不为过，故选B。29C解析：C【详解】句意：你为什么不早点告诉我？ 我为什么应该告诉你？我想要保守我自己的秘密。 考查情态动词。can能够；may可以；should应该；shall将，会。根据“Why didnt you tell it to me earlier?”及“I want to have my own secret.”可知，此处应该是“我为什么应该告诉你？”故选C。30A解析：A【详解】句意：布莱克先生现在不可能在家。他上周五去国外度假了。考查情态动词词义辨析。cant不可能，不会；mustnt禁止；neednt不需要；shouldnt不应该。根据“He went abroad on vacation last

be，一定有”，表示肯定的推测。故选C。34C解析：C【详解】句意：那边那个人是谁？ 是布莱克先生吗？ 不可能是他。布莱克先生比那个人高得多。 考查情态动词。may可能；must一定；cant不可能；musnt禁止。根据“Mr. Black is much taller than that man.”可知，这个人不可能是布莱克先生。故选C。35A解析：A【详解】句意：我可以看你的身份证吗？我们必须检查一下你的个人信息。当然可以。给你。考查情态动词。may可以，表请求或许可；need需要，指有必要；should应该，表建议；must必须，强调主观意愿。根据答语“Sure.
