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。2B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。3C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

red”可知，现在是红灯，禁止过马路，故选C。7D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。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

to，故选C。11A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。12A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。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

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。17A解析：A【详解】句意：很多在线资源既可以供学校的老师使用，也可以供家长在家使用。考查情态动词词义辨析。can能，可以；should应该；need需要；must必须。根据“be used either by teachers at school or parents at home.”可知，指很多在线资源既可以供学校的老师使用，也可以供家长在家使用。故空格处的意思是可以，能够。故选A。18C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。19B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。20A解析：A【解析】句意“这个小男孩非常的勇敢，我敢说，他敢爬上那棵高的树”。dare既可作情态动词，也可作实意动词。做情态动词时，无人称与数的变化，且空后用动词原形；做实意动词时，有人称和数的变化，用dare to do sth。第一空排除C。第二空即可写成dare climb也可写成dares to climb，故选A。21C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。22B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强调客观需要。根据 “My bike was broken yesterday我的自行车昨天坏了”可知，此处表达“所以我不得不步行回家”，用情态动词的过去式had to表示“不得不”。故选B。23D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。24B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】25D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。26C解析：C【详解】句意：我认为所有的学生都喜欢周末，因为对他们来说，他们不必在周六或周日早起。考查情态动词。mustnt禁止；dont need不需要；neednt不必；cant不能。根据“to them, they . get up early on Saturdays or Sundays”结合常识可知周六或周日学生么不必早起。根据“get”可知，此处是neednt do sth短语，故选C。27D解析：D【详解】句意：你不应该要求别人像你一样来处理问题。每个人都有自己的方法。考查情态动词。mustnt不许，表禁止；neednt 不必；may not 也许不；shouldnt不应该；根据“ Everyone has his own way”每个人都有自己的方法；可知，此处指“不应该如此要求别人”。故选D。28B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。29B解析：B【详解】句意：孩子们明天早上六点必须离开吗？ 不，他们不必。他们可以有更多的时间为旅行做准备。考查情态动词辨析。cant不能；neednt不必；mustnt禁止；may not可能不会。根据“Must the children leave at six tomorrow morning?”可知，此处为Must引导的一般疑问句，否定答语要用needt或dont have to，故选B。30B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。31B解析：B【详解】句意：一个努力的人可能不会成为一位伟大的科学家，但一位伟大的科学家一定是一个努力的人。考查情态动词表推测。第一个空，cant表示“不能”或“不可能”，may not表示“可能不”，根据语境可知，努力的人可能成为伟大的科学家，也可能不会成为，因此排除选项A和C；第二个空，must be表示“一定是”，can be表示“有时是、可以是”，根据题干前半句和but转折可知，此空应用肯定推测，即must be，排除选项D。故选B。32D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。33C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 described every detail of the accident just

great height.”可知，从高空中掉落一个小的物体都有可能造成伤害或死亡，表示可能性用may，故选C。36A解析：A【详解】句意：妈妈，为什么我必须一天洗那么多次手？为了你的健康，你越小心越好。考查情态动词。cant不可能；mustnt禁止；may not可能不；neednt不必。cant be+too+形容词，表示越越好，故选A。37A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.
