Must (必须)含义: 表示说话人认为非常强烈的义务、必要性或命令。语气最强。特点: 通常来自于说话者个人的权威或观点。例句:I must finish my homework today. 我今天必须完成作业。(我自己认为有必要)You must be quiet in the library. 在图书馆你必须保持安静。(规定或命令)否定形式:must not / mustn't (表示“禁止”,见下文)2. Have to (不得不,必须)含义: 表示由于外部规则、法律、情况或要求而必须做某事。客观必要性。特点: 可用于各种时态(如过去时 had to, 将来时 will have to)。例句:We have to wear school uniforms every day. 我们每天必须穿校服。(校规要求)He has to go to work now. 他现在得去上班了。(工作需求)Must vs. Have to 区别:Must 更主观(我觉得必须)。Have to 更客观(外部规则要求必须)。很多时候可以互换,但细微感彩不同。3. Should (应该)含义: 表示建议、劝告或认为某事是好的、正确的。语气比 must 弱很多。特点: 不是强制性的,只是表达一种观点。例句:You should eat more vegetables. 你应该多吃蔬菜。(健康的建议)He should apologize to her. 他应该向她道歉。(我认为这是对的)否定形式:should not / shouldn't (表示“不建议做某事”)You shouldn't watch TV for too long. 你不应该看太久的电视。三、 表示“禁止” (You cannot do something)告诉人们绝对不要做某事。1. Must not / Mustn't (严禁,不准)含义: 表示强烈的禁止,是语气最重的“不许做某事”。通常来自规则或权威人物。例句:You mustn't play with fire. 你严禁玩火。(非常危险)Students must not use mobile phones in class. 学生不准在课堂上使用手机。(校规)2. Can not / Can't (不能,不许)含义: 表示“不允许”,语气比 mustn't 稍弱一些,但也明确表示禁止。常用于口语中告知规则。例句:You can't park your car here. 你不能在这里停车。(规定不允许)Sorry, you can't go out now. 抱歉,你现在不能出去。(我不允许)Mustn't vs. Can't 区别:在表示“禁止”时,两者常常可以互换,但 mustn't 强调“义务上的禁止”(你有一项义务不去做这件事),而 can't 强调“能力或权限上的不允许”(你没有能力或权限去做这件事)。对于初学者,可以先将它们都理解为“不准”。四、 总结与对比表格情态动词 含义与语气 例句 否定形式及含义Must 必须 (主观性强,语气最强) You must see a doctor. must not / mustn't (严禁,不准)Have to 必须,不得不 (客观规则,语气强) I have to wear a tie at work. do not have to (不必,表示没有义务)Should 应该 (建议,语气较弱) You should try your best. should not / shouldn't (不应该,建议不要)Can't 不能,不许 (禁止或不允许) You can't smoke here. (本身就是否定形式)Mustn't 严禁,绝对不可以 (强烈禁止,语气最强) You mustn't tell lies. (本身就是否定形式) 特别注意:Must 的否定 mustn't 表示禁止。Have to 的否定 don't have to 表示不需要( lack of necessity),而不是禁止。You don't have to wear a uniform today. (今天不是必须穿校服,但穿也可以。) -> 表示选择You mustn't wear jeans today. (今天绝对不准穿牛仔裤。) -> 表示禁止1.—________ you eat in the classroom —No, we ________ eat in the dining hall.A.Can, can’t B.Must, can C.Can, must2.It is ________ important a meeting ________ everyone must attend it.A.such; that B.so; that C.too; to D.as; as3.Architects enjoy designing creative buildings. ________, they must follow strict safety rules.A.For example B.Therefore C.However D.And4.—We must take action to protect the environment.—There’s a lot we can do. ________, we should let more people realize the importance of going green.A.Above all B.Of all C.Moreover D.Otherwise5.A hard-working man ________ be a successful man, but a successful man ________ be a hard-working man.A.may not; can B.can’t; may C.may not; must D.can’t; should6.We must do something to save those animals in ________.

hall.”及选项可知,后半句需用“must”表示强制规定“必须在食堂吃”,前半句用“Can”询问许可,故选C。2.B【解析】句意:这是一个如此重要的会议,以至于每个人都必须参加。考查so ... that引导的结果状语从句。such ... that如此……以至于,such修饰名词;so ... that如此……以至于,so修饰形容词或副词;too ... to太……而不能,to后跟动词原形;as ... as和……一样。根据“important a meeting ... everyone must attend it.”可知,是指如此重要的会议,以至于每个人必须参加,用so+形容词+a/an+名词单数+that从句。故选B。3.C【解析】句意:建筑师喜欢设计有创意的建筑。然而,他们必须遵守严格的安全规则。考查副词的用法。For example例如;Therefore因此;However然而;And和。根据“Architects enjoy designing creative buildings.”和“they must follow strict safety rules.”可知,前后句为转折关系,喜欢有创意的建筑,但是要遵守安全规则,空处填表示转折关系的副词However。故选C。4.A【解析】句意:——我们必须采取行动保护环境。——我们能做的有很多。尤其是,我们应该让更多人意识到环保的重要性。考查副词辨析。Above all尤其是;Of all在所有……之中;Moreover此外;而且,表示递进关系;otherwise否则;不然,表示转折或不满足条件的结果。根据“There’s a lot we can do. …we should let more people realize the importance of going green.”可知,空白处需要一个表示强调或最重要的过渡词,Above all用于强调首要行动,符合上下文强调让更多人意识到环保重要性的逻辑。故选A。5.C【解析】句意:一个勤奋的人可能不会成为一个成功的人,但是一个成功的人一定是一个勤奋的人。考查情态动词辨析。may not可能不;can可能;can’t不可能;may可能;must必须,一定;should应该。根据“A hard-working man...be a successful man”可知,第一空表达“可能不”,用may not;根据“a successful man...be a hard-working man”第二空表达肯定的推测“一定”,用must。故选C。6.D【解析】句意:我们必须做些什么来拯救那些处于危险中的动物。毕竟,它们是我们的朋友。考查名词辨析。price价格;hurry匆忙;truth真相;danger危险。根据“save those animals”可知,是指拯救处于危险中的动物,in danger“处于危险之中”。故选D。7.B【解析】句意:——我们完成这项任务只剩下三个小时了。——我们必须及时完成它。所以每一分钟对我们来说都重要。考查动词辨析。passes通过;count计数、重要;runs跑;flies飞。根据“We must finish it in time.”以及选项可知,此处表示每一分钟对我们来说都重要。故选B。8.A【解析】句意:——这个星期六去野餐怎么样?——听起来很棒。一定很有趣。考查情景交际。Sounds great听起来很棒;What a shame真遗憾;You’re kidding你在开玩笑。上文“How about having a picnic this Saturday ”提议去野餐,结合答语“It must be fun.”可知,此处是指这个建议听起来很棒。故选A。9.A【解析】句意:我们必须尽最大努力,争取下次赢得比赛。考查动词形式辨析。try尝试,动词原形;to try尝试,动词不定式;trying尝试,现在分词;tried尝试,动词过去式。must为情态动词,后需跟动词原形。故选A。10.B【解析】句意:足球是一项团队运动。我们必须团队合作。考查名词和形容词辨析。individual个人的;team团队;easy容易的;difficult困难的。根据后一句“We must play as a team.”可知,此处应该填入team,表达足球是一项团队运动。故选B。11.D【解析】句意:我现在必须把我朋友的相机还给她,因为我已经借了两个月了。考查现在完成时的用法。have borrowed借入,瞬间性动词;have bought买,瞬间性动词;have lent借出,瞬间性动词;have kept保留,延续性动词。“I must return my friend’s camera”可知,此处指借入相机两个月了;根据“for 2 months”可知,动作从过去持续到现在,需用现在完成时,且动词要用延续性动词,用have kept。故选D。12.C【解析】句意:——你能帮我们换一下这个灯泡吗?——没有问题。但是你必须先关掉电源。考查情态动词辨析。can可以;must必须。第一空,根据“No problem.”可知,第一空表示请求,应填can;第二空,根据“But you... turn off the power first.”可知,换灯泡时必须关掉电源,应填must。故选C。13.B【解析】句意:旅行时,你可以带两个包,但它们不能太重。考查连词辨析。for因为;but但是,转折连词;or或者;so因此,因果关系。前半句说“能拿两个包”,后半句说“不能太重”,存在转折逻辑,应该使用but表示转折关系。故填B。14.A【解析】句意:——这个铅笔盒是约翰的吗?——不,他的是黑色的。这个一定是你的。考查名词性物主代词。his他的,形容词性物主代词或名词性物主代词;him他,人称代词宾格;he他,人称代词主格;yours你(们)的东西,名词性物主代词;your你(们)的,形容词性物主代词。根据“No, ...is black.”可知,第一空作主语,用名词性物主代词his,表示“他的铅笔盒”;根据“This one must be...”可知,第二空作表语,也用名词性物主代词yours,表示“你的铅笔盒”。故选A。15.B【解析】句意:——听!谁在音乐教室唱歌?——一定是简。她通常每天这个时候唱歌。考查动词时态。根据“Listen!”可知,动作正在进行,应用现在进行时“is singing”;根据“usually”和“every day”可知,是经常性、习惯性的动作,应用一般现在时,主语“She”是第三人称单数,谓语动词用“sings”。故选B。16.B【解析】句意:学生上学时必须穿校服。考查动词辨析。put on穿上,强调动作;wear穿着,强调状态;in在……里面,介词;dress给……穿衣服。根据“Students must ... their school uniforms”可知,must后跟动词原形,此处强调穿着校服的状态。故选B。17.D【解析】句意:——看!我父母正在为端午节包粽子。——我想一定很好吃。考查现在进行时。根据“Look!”可知,此处描述正在进行的动作,需用现在进行时,结构为am/is/are doing。主语“My parents”是复数,be动词用are;make的现在分词为making。故选D。18.B【解析】句意:——我打算去英国旅游,但是我的护照不见了。没有它我能去旅游吗?——当然不行。你必须得有一本新的。考查名词辨析。postcard明信片;passport护照;dollar美元。根据“I plan to visit England, but my…is missing.”可知,此处是在描述打算去英国旅游,但是护照不见了。故选B。19.D【解析】句意:我们学校的学生在平日必须穿校服。考查名词辨析。weekends周末;holidays假日;festivals节日;working days工作日。根据“Students in our school must wear their uniforms on weekdays.”可知,学生必须穿校服的时间是工作日,所以划线词意为“工作日”,与“working days”同义。故选D。20.A【解析】句意:充足的睡眠对我们的健康是必要的,所以我们不能熬夜。考查形容词词义辨析。necessary必要的;terrible可怕的;excellent优秀的;enjoyable愉快的。根据后句“so we mustn't stay up late.”可知,应是充足的睡眠对我们的健康是必要的。故选A。21.A【解析】句意:——我现在必须完成我的家庭作业吗?——不,你不必。你或许可以明天做。考查一般疑问句。Must提问的一般疑问句,否定回答一般用No, you needn't.或No, you don't have to.;mustn't表“禁止”,语气非常强烈,不符合语境;回答的第二句用了You,主语要一致,所以回答的第一句主语也是you,故选A。22.C【解析】句意:——-我可以在这里游泳吗?——对不起。孩子们禁止在这里独自游泳。这很危险。考查情态动词。must必须;can't不能;may可以;mustn't禁止;can可以,能够。根据句意,首空问的是“可以在这里游泳吗?”,表示询问,用may/can;第二空根据“It's very dangerous.”可知“孩子们禁止在这里独自游泳”是一条规定,涉及到危险,语气严格,用mustn't。故选C。23.A【解析】句意:——我必须现在洗衣服吗?——不,你没必要。你可以先做作业。考查情态动词的用法。must必须;shall表示提出或征求意见;(表示决心、命令或指示) 必须,一定,应该;根据“你可以先做作业”,可知不必现在洗衣服,而mustn't表示禁止,意为“千万不要”,所以排除D,而don't need中,need为实意动词,其否定回答为You don't need to,当其为情态动词时,其否定回答为You needn't,所以B项错误,don't have to意为“没必要”,故选A。24.D【解析】句意:——妈妈,我今晚能看电视吗?——当然,但是你必须先完成作业。考查情态动词辨析。can可以,may可以,两者都可以引导一般疑问句表示请求。mustn't表禁止;could能够;can't不能;must必须。根据语境可知,妈妈表示必须先完成作业才能看电视,故第二空格处应用情态动词must表必须。综上所述,D选项两空均正确。故选D。25.C【解析】句意:——看,史密斯老师办公室的灯还亮着,她肯定还在那里工作。——不可能是她。她已经去北京了。考查情态动词。must必须;mustn’t禁止;can可以;can’t不可能。此处运用情态动词表示推测的用法。由“办公室的灯还亮着”可以肯定地推测人还在办公室里,用must;根据“她已经去北京了”可知办公室的人不可能是她,否定地推测用can’t。故选C。【点睛】情态动词表示推测时,must用于对现在或将来情况作推测,意为“一定”,通常只用于肯定句,一般不用于否定句和疑问句;can的意思是“可能”,用于对现在或将来的情况作推测,主要用于否定句和疑问句,用在肯定句中的情况较少,考生们也可据此来判断这题。26.D【解析】句意:孩子们,你们不可以走得太靠近山路的边缘,因为你们可能会掉下去,伤害到你们自己。考查反身代词。themselves他们自己;ourselves 我们自己;yourself 你自己;yourselves你们自己。根据boys and girls是名词复数形式,所以空格处是填复数的反身代词,排除C选项。根据句子的主语you, 可知此处表示“伤了你们自己”,反身代词在人称上要与主语保持一致,用yourselves。故选D。27.A【解析】句意:我能带狗进公园吗?——对不起,你不可以。这是不允许的。考查情态动词。May可能;Can能够;Must必须;一定;mustn’t不可以;禁止;needn’t不需要。第一个空为表示请求、允许,用情态动词may;根据“It's not allowed.”可知第二个空应该为“不可以”,用mustn’t表示。故选A。28.C【解析】句意:——我们必须一直保持房间足够干净吗?——不,没必要。考查情态动词的问答。根据句意,可知是用情态动词提问,意为“是不是必须”,而不是用助动词询问是否做了,排除B;用must提问,否定回答用don’t/doesn’t have to,意为“没必要”,又根据第二空主语you为第二人称,所以用助动词don’t,故选C。【点睛】用情态动词must提问,其肯定回答用must,否定回答用needn’t或don’t/doesn’t have to,意为“没必要”;注意否定回答千万不能用mustn’t,意为“禁止”。29.B【解析】句意:——我必须先做作业吗 ——不,你不必。考查情态动词辨析。must必须,强调主观意愿;mustn’t不能,表禁止;may可以,表许可;could能够,否定式是couldn’t,表能力或许可;don't have to不必;won't一般将来时的否定式。根据句意语境,可知前句问“我必须先做作业吗”,需用must;must开头的一般疑问句,否定回答不可用mustn't,而用needn’t或don't have to;故选B。30.D【解析】句意:我们千万不要打破学校的规章制度。考查动词辨析。A. obey遵守,遵循;B. keep保持,遵守; C. follow跟随,按照; D. break打破,违背,根据句意“不要打破学校的规章制度”,故选D。31.B【解析】句意:当我们在公共场合时,不准到处乱扔垃圾。考查动词的辨析。A. make制作,使得;B. leave留下,离开;C. use使用;D. get获得。分析句子可知,这里是指“扔垃圾”,用leave rubbish。故答案选B。32.A【解析】句意:——看!那个人一定是我们的校长。他每天早上都站在那儿。——不,不可能是他。他现在正在办公室开会。分析上句,根据He's always standing there every morning.可判断,那个人一定是我们的校长;故用must,表示肯定推测,排除C、D。分析下句,根据He is
