B.can C.will D.Should【答案】B【解析】分析题干，可发现这是could引导的一般疑问句，用于请求别人允许自己做某事，回答时要用can,因此选B。2.常见的情态动词辨析类别用法例句can/could/beableto的区别can和could只能用于一般现在时或一般过去时，而beableto可用于各种时态；beableto可与情态动词连用，can则不能。IcouldplayfootballverywellwhenIwasatschool,butnowIcan't.我在学校的时候可以踢得很好，但现在我不能了。Ican/amabletoaffordthenewcomputer.我可以/负担得起这台新电脑。can更侧重于表达主语本身就具备的能力，这种能力是内在的、固有的。而beableto则更侧重于描述通过努力或学习后获得的能力，或者是在某个具体条件下才能实现的可能性。Shecansinghighnotesnaturally.她天生就能唱高音。Aftermonthsofpractice,hewasfinallyabletoplaythatcomplexpianopiece.经过几个月的练习，他终于能够弹奏那首复杂的钢琴曲了。can和could表示能力、允许、许可或推测，但beableto只表示能力。Youcantakethisseat,ifyouwant.如果你愿意，你可以坐这个座位。表示成功地做了某事时，只能用was/wereableto，这时was/wereableto相当于managedto,表示经过一番努力,终于能够完成某事。HewasabletofleeEuropebeforethewarbrokeout.他在战争爆发前就已经逃离了欧洲。=HemanagedtofleeEuropebeforethewarbrokeout.must和haveto的区别must只有现在时一种形式（在宾语从句中可以表示过去）,而haveto则有多种时态形式。Shesaid(that)shemustgowithme.她说她一定要同我一起去。

Youdon’thavetotellhimaboutit.你不必告诉他这件事。need作实义动词时，主要用于肯定句中，有人称、时态和数的变化，后常接带to的不定式。其否定式和疑问式都要借助助动词do。Heneedssomemoneytobuynewclothes.他需要一些钱来买新衣服。dare用作实义动词，有人称、时态和数的变化，意为“敢于”。肯定句中要跟带to的不定式，而在否定句或疑问句中to可要可不要。Idonotdare(to)complainaboutthehardwork.(=Idarenotcomplainaboutthehardwork.)我不敢抱怨工作辛苦。★知识点3考点和题型考点1情态动词辨析考查题型单项选择、完形填空—DoIhavetohandinmyreportnow?We'regoingtodiscussit.—Ofcourse,you_______.A.can B.can't C.must D.mustn't【答案】C【解析】句意:—我必须现在交我的报告吗？—当然了，你必须交。我们马上要讨论了。根据“We'regoingtodiscussit.”可知，此处是肯定回答。由haveto构成的一般疑问句，肯定回答用must；否定回答则用needn't或don't/doesn'thaveto。故选C。步骤一：阅读题干，根据句子的意思判断空格需要填入的情态动词的意义。步骤二：分析选项中情态动词的用法，结合上下文的语境判断选出正确答案。考点2情态动词填空考查题型单句填空、语篇填空（2024·安徽芜湖·二模）Whenthezoohadtoc________
