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。20C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。21B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

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。24A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。25A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。26D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 today”可知，推测那个男孩一定不是汤姆，否定推测用cant，故选D。27C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。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。29C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。30B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。31C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。32B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。33B解析：B【详解】句意：那位年轻女士的工作是什么？她可能是个护士，我不确定。考查情态动词。must必须；may可能；need需要；would将会；根据“Im not sure.”可知，此处是不确定的推测，表示“可能”，应用may，故选B。34A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。35D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。36C解析：C【详解】句意：那是周先生吗？肯定不是他。他去了北京。考查情态动词。can能，能够；may可能；can t不可能，表示推测；shouldnt不应该；根据“He has gone to Beijing.”可知，那个人不可能是周先生，故选C。37A解析：A【详解】句意：谁在隔壁唱歌？是王小姐吗？不可能是她。她正在开董事局会议。考查情态动词表推测。cant不可能是，表示有把握的否定推测；shouldnt不应该；mustnt禁止；neednt没必要。根据“Shes having the board
