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。4C解析：C【详解】句意：我们不应该从大楼上扔任何物体。当从很高的高度掉落时，即使一个小的物体可能导致严重的伤害或死亡。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 objectcause serious injuries or death,when dropped from a 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。5D解析：D【详解】句意：我们的化学老师总是告诉我们考试前怎样用功都不为过。考查情态动词辨析。mustnt不能，表禁止；shouldnt不应该，表建议；neednt不必，指没有必要；cant不能，表没有能力或不许可。根据题干“webe too hardworking before the exams”，可知是“cant be too +形容词”结构，表示“再也不为过”。故选D。6B解析：B【详解】句意：这周五郎朗会去艺术中心表演吗？是的。一定是他。他在这里已经三天了。考查情态动词。might也许；must必须；mustnt禁止；may也许。根据“Yes.”和“He has been here for three days.”可知，此处表示非常肯定的推测，故选B。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。8D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。9C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。10A解析：A【详解】句意：妈妈，我现在必须打扫房间吗？ 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。11A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。12A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。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”。14A解析：A【分析】【详解】句意：埃米，我听说你有许多外国硬币，我可以看一看吗？当然，我去给你拿来。 考查情态动词辨析。May可以，表示请求许可；Must必须，强调主观愿望；Should应该，指主语的责任与义务；Need需要，必须。本题表示“请求”看看硬币，用may，故选A。15C解析：C【详解】句意：你应该非常重视你的发音，因为它在口语考试中如此重要。shouldnt不应该，mustnt禁止，cant 不可能， neednt 不必。cant too much太也不过分，故选C。16B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。17D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。18B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】19A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。20B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。21C解析：C【详解】句意：我现在就告诉他时间改变了，好吗？恐怕你必须这么做，否则他开会就要迟到了。考查情态动词辨析。can能够，表能力或许可；may可以，表推测；must必须；need需要。根据下文“otherwise he will be late for the meeting”，可知ABD三项不合语境，这里是说必须告诉他时间改了，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

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。28D解析：D【详解】句意：那边的男孩是汤姆吗？他经常穿那样的夹克。那不可能是他。他今天没来上学。考查情态动词。neednt不必；shouldnt不应该；mustnt禁止；cant不可能。根据“He is absent from school

the Pacific Ocean”可知，对于日本政府向太平洋排放核废料这个行为，我们是必须要阻止的，用must表示“必须”。第二个空是固定搭配：be bad for“对有害”，故选C。33C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,
