days.”可知，此处表示非常肯定的推测，故选B。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。3D解析：D【详解】句意：对不起，这里不允许抽烟。如果你一定要抽的话，你会被按规定罚款的。考查情态动词辨析。can能、会；will将要；may可以；must必须、一定。根据主句“you will be fined according to the rules.”可知，应是如果你一定要抽的话。故选D。4A解析：A【详解】句意：我真的有必要带着口罩去购物吗？恐怕在公共场合你必须如此。这不仅是保护自己，也是保护他人。考查情态动词。must必须；should应该；can可以；need需要。根据“It is not only to protect yourself but also to protect others.”可知在公共场合必须戴口罩。故选A。5C解析：C【详解】句意：我可以加入你的计划吗？对不起，你不能。你太年轻了。考查情态动词。shouldnt不应该；mustnt禁止；cant不能；neednt没必要；根据“You are too young.”可知，你太年轻了，由此说明你不能参加对方的计划。故选C。6C解析：C【详解】句意：你觉得我的新裙子怎么样？ 好吧，如果我不得不说的话，它不适合你。 考查情态动词。may可以；must必须（有义务、有必要）；have to不得不（客观情况驱使）；should应该。根据“if Isay, it is not suitable for you.”可知，此处表示客观情况驱使，因此用have to“不得不”。故选C。7B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。8C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。9C解析：C【详解】句意：你应该小心你的相机。它很贵！考查情态动词辨析。can可以；will将；should应该；may可能。根据“It costs!”可知相机很贵，应该小心。故选C。10A解析：A【详解】句意：你能帮我一把吗？我一个人贴不起海报。没问题。考查情态动词辨析。Could能、会（用在问句中表示委婉语气）；Should应该；Need需要；Must必须。根据“I cant put up the poster by myself.”可知，此处表示请求，用委婉语气表达“能”帮一下吗。故选A。11C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。12A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。13B解析：B【详解】句意：汤姆在哪里？我正在考虑告诉他考试的结果。哦。你不必。他已经知道这件事了。考查非谓语动词和情态动词。cant不可能；neednt不必；mustnt禁止；shouldnt不应该。consider doing sth.考虑做某事，第一空用telling；再由“He has known it already.”可知他已经知道考试结果，不必再告诉他，第二空用neednt。故选B。14D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。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

depends.”可知，出国深造的可能性不是很大，大概是50%左右，表示50%左右的可能性，“may”符合句意，故选C。17B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。18B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。19B解析：B【详解】句意:我的自行车昨天坏了，所以我不得不步行回家。考查情态动词。might可能；had to必须，不得不；must必须，一定；could能，会，是can的过去式。must强调说话者的主观看法，have

to表示“不得不”。故选B。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,
