all”可知，拼写错误是不被允许的，所以报告必须重写。故选A。2A解析：A【详解】句意：做决定前要三思，否则你可能会惹上麻烦。考查情态动词。may可能；cant不能；shouldnt不应该；mustnt不允许；根据语境理解可知，此处表达的是“可能”，是一种不太肯定的推测，英语用may，故选A。3B解析：B【详解】句意：为了避免聚会，我们最好在网上开家长会。考查非谓语动词及动词的基本形式。avoid doing sth.“避免做某事”；Wed better+动词原形，我们最好做某事；gather是动词，聚集；hold是动词，举行，第一空用动名词，第二空用动词原形，故选B。4C解析：C【详解】句意：快点，否则我们可能会错过电影的开头。考查情态动词。should应该；must必须；may可能；have to不得不。根据语境可知，此处表推测，故应用情态动词may。故选C。5B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。6B解析：B【详解】句意：妈妈，为什么我进超市前要戴口罩？ 为了你的健康和安全，你再小心也不为过。考查情态动词辨析。shouldnt不应该；cant不能；mustnt不允许；neednt不必。根据“For your health and safety, you.be too careful.”可知，为了你的健康，你再怎么小心也不为过，“cant.too.”表示“再也不为过”。故选B。7C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。8C解析：C【详解】句意：小心！火有时候会很危险。好的。我马上把火扑灭。考查情态动词辨析。mustnt禁止；should应当；can会、能；neednt不需要。根据前句“Be careful!”可推知，应是说火有时候会很危险，故情态动词应用can。故选C。9C解析：C【详解】句意：我们青少年应该有梦想。有梦想和努力，任何惊人的事都能被创造。考查情态动词。may可能；can能够；should应该；might可能；has to不得不；must必须。第一个空表示“应该”，用should；第二个空表示能力，用can。故选C。10A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。11A解析：A【详解】句意：我可以喝点酒吗？不，你不能。你一会儿得开车回家。考查情态动词。mustnt不可以，表禁止；neednt不需要；cant不可能；may not可能不是。上句询问能否喝点酒，结合“drive home”可知，开车不能喝酒，表禁止，故用mustnt。故选A。12D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。13B解析：B【详解】句意：我听不清你说什么。你能重复一下吗？考查情态动词。mustnt禁止；cant不能；neednt不需要；shouldnt不应该。根据“Would you please repeat it?”可知，我不能听清，所以需要对方重复，故选B。14A解析：A【详解】句意：神奇的是，这支笔能把声音转换成文字，而且很少出错。考查情态动词词义辨析。can能够，可以；must必须；may可以，可能；need需要。此句是说这支笔能够把声音转换成文字，表示一种能力，应用can，故选A。15C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。16B解析：B【详解】句意：请不要发出那么多噪音。我不能很好地听清楚发言者的话。考查情态动词辨析。neednt不必，指没必要；cant不能，指不能够；shouldnt不应该，表建议；mustnt不能，表禁止。根据上文“Please dont make so much noise”可知，别人发出了太多噪音，所以他“不能够”听见演讲者的话，需用情态动词cant。故选B。17A解析：A【详解】句意：你今晚会早点回来吗？ 是的，但我可能会晚一点。我们的老板有时有额外的工作要做。A. may也许；B. must必须；C. need需要；D. will将，将会。由下文的句子Our boss sometimes has extra work for us. 我们的老板有时有额外的工作要做。可知，今晚我可能会晚一点回来。因此用may be表示推测；选项B/C/D不符合语境。故选A。18D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”。19B解析：B【详解】句意：你妈妈这周六将在家吗？很难说。她可能去乡下看我的祖父母。考查情态动词辨析。must一定，表示有把握的推测；may可能，表示没有把握的推测；can可以，表示允许；would愿意，表示意愿。根据“Hare to say”可知，此处表示没有把握的推测，因此用may，故选B。【点睛】20D解析：D【详解】句意：我的车今天能修好吗？应该能，先生，如果有什么问题我会打电话给你。考查情态动词辨析。must必须，一定，表推测时，语气最肯定；could可能，表推测时，其意很不肯定；shall将，会；should应当，应该，表示推测时，其语气比较肯定，它通常指非常可能的事，并暗示其推测有一定的事实依据或者合乎常理。根据“Ill call if theres any problem”可知，是说话人按照事实有一定依据的推测，用should符合语境。故选D。21C解析：C【详解】句意：汤姆，看看地板！你吃饭时必须看电视吗？考查情态动词辨析。Should应该；Could能，会；Must必须；May可以。根据“Look at the floor, Tom!”可知，此处是抱怨必须吃饭看电视，用情态动词must。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。23D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。24C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

Beijing.”可知，那个人不可能是周先生，故选C。26C解析：C【详解】句意：切勿将物体从建筑物中扔出去。从高处坠落时，即使是小物体也可能造成严重伤害或死亡。考查情态动词辨析。must必须；should应该；may可能；need需要。根据“Even a small object.cause serious injuries, or death, when dropped from a
