19、,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。6C解析:C【详解】句意:爸爸,我们一定要等绿灯吗?是的,恐怕我们必须这样做。这是交通规则。考查情态动词。may可能;can可以;have to必须;need需要;根据“must we wait until the light becomes green”及“Thats the traffic rule”可知,每个人都必须要遵守交通规则,应用have to,故选C。7A解析:A【详解】句意:锻炼是有帮助的但是它
20、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。8A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。9C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
21、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。10A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。11B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。mus
22、t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。12B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。13A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

24、ould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。16A解析:A【详解】句意:准备好了吗?我们开始吧,马丁。游泳?我只是不能习惯冬天游泳。考查情态动词。cant不能;neednt不必;mustnt禁止;shouldnt不应该。根据getusedtoitinwinter“习惯冬天游泳”可知,应该是“不能”习惯冬泳,用cant,故答案选A。17A解析:A【详解】句意:钟南山院士曾经说过:“要预防这一疾病的传播,我们多么小心也不
25、为过。”考查情态动词。can能、能够;may可以;must必须;should应该。can的否定式和too或enough 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。18A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。19B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
