2.C
考查情态动词。may可能;can能够;have to不得不;need需要。根据“For your health”,可知是医生的建议,表示客观需要做的事情,用have to。故选C。
3.D
考查情态动词辨析。couldn’t不可以;wouldn’t将不;can’t不能;needn’t不必。根据“I’m feeling much better now”可知,好多了所以不必叫医生,故选D。
4.A
对于must打开头的一般疑问句必须用needn’t来作否定回答。根据句意,故选A。
5.C
考查情态动词的一般疑问句。Must +主语 do sth. 肯定回答是Yes,….must.否定回答是No,…needn’t.或No,…don’t/doesn’t have to.结合句意和选项可知填don’t have to;选C。
6.D
A. can’t不能;B. mustn’t禁止;C. shouldn’t不应该;D. needn’t不必。根据题意,表示不必给母亲买礼物。故选D。
7.D
can’t不能;mustn’t禁止,不允许;shouldn’t不应该;needn’t不必。对must开头的一般疑问句做否定回答,习惯用needn’t。所以选D。
8.C
试题分析:may:可能、或许;can:能、会;have to:必须、不得不(表客观要求),must:必须(表主观愿望)。根据题意“为了健康,你必须戒烟”。故选C
9.A
考查情态动词。needn’t没必要;may可以,可能;mustn’t禁止;need需要;must必须,一定。根据“Must I wash my clothes at once, mom ”可知,第一空为Must引导的一般疑问的否定答语,要用needn’t或don’t have to,所以第一空用needn’t;根据“wash them before 5:00 p.m.”可知,没必要现在洗衣服,可以在下午五点前洗,第二空用“may”表示“可以”。故选A。
10.D
A. shouldn’t 不应该; B. wouldn’t 不愿意;C. mustn’t 禁止;D. needn’t不必。must或need位于句首提问的一般疑问句肯定回答用Yes,...must. 否定回答用No,...needn’t/don’t have to.故选D。
11.C
考查情态动词。needn’t不必;left 是leave的过去式;mustn’t禁止,不允许;leaving是leave的现在分词或动名词形式;can’t不可能;leave 离开;shouldn’t不应该。see sb do sth看见某人做某事。所以选C。
12.A
must的含义是必须一定,其否定形式mustn’t表示禁止的含义。故must的否定回答一般借助于needn’和don’t have to来构成。句意:我必须现在就完成我的作业吗?——不,你不必。现在你可以回家。结合语境及所给选项,可知选A。
13.C
考查情态动词和动词。mustn’t禁止;needn’t不必;keep保存;lend借出;borrow借入。根据“Must we return the book to the library today ”和“No”可知,对must的疑问句进行否定回答要用needn’t;再根据“for two weeks”是一段时间,要用延续性动词keep。lend与borrow是非延续性动词,故选C。
14.D
考查非谓语和固定短语。第一空stay是动词,need是情态动词或实义动词,表主动时后接do或to do,排除B;第二空stay是名词,a short stay表示“一次短暂的停留”。故选D。
15.A
考查非谓语动词。stop doing sth.停止做某事(正在做的事情),stop to do sth.停下来去做某事(去做另一件事情),都是固定结构;had better最好,是情态动词,后面接动词原形,排除CD两项;根据“You look tired”,可知应该停下来去休息,故选A。
16.A
needn't不必,表示必要性;mustn’t禁止;can’t不能,表示没有能力;couldn’t是can’t的过去式,表示不能。Must I……?“我必须……吗?”肯定回答用Yes, you must.否定回答用No, you needn’t.或No, you don’t have to.根据No可知此处用否定回答,故选A。
17.D
考查“had better(not)do sth”结构。分析句子可知,此处表示否定含义“不要一个人在河里游泳”,排除B和C;又因为此处用于“had better(not)do sth”结构中,所以此处使用动词原形。故选D。
18.C
你可以借20天。must I do … 否定回答是,No, you needn’t .和一段时间连用,动词用延续性。borrow对应的延续性动词是keep,故选C。
19.A
A. needn’t不必,不需要;B. can’t不能;C. mustn’t一定不要;D. shouldn’t不应该。根据With their new lock, you __________ search for keys in your bag any more. 有了他们的新锁,你就_______ 再在包里找钥匙了。可知,应该选择needn’t不必,不需要;符合语境。故选A。
20.B
第一空作为主语,故用动名词形式learning。第二空谓语情态动词should之后,故用动词原形practice,故选B。
21. can’t draw
原句中含有情态动词“can”,否定直接在can后加not,后接动词原形,can not可以缩写成can’t;故填can’t;draw。
22. call at
句意:你可以打电话Cindy。她的电话号码是149-2486。此句可改为call sb at+电话号码的用法,can是情态动词,后接动词原形,故填call;at。
23. can’t play
根据“can”可知,改为否定句,直接在情态动词后加not;故填can’t;play。
24. Would like
考查陈述句改成一般疑问句,将情态动词would提前到句首,句首字母大写,其他不变,所以第二空用like。故填Would;like。
25. not ask
句中“had better”意思是“最好”,是情态动词,后接原形动词,用于建议或警告;其否定式在“better”后面加not,是固定结构,故填not; ask。
26. doesn’t have
has to的否定是doesn’t have to。故填doesn’t;have。
27. not any
had better (not) do sth.“最好(不)做某事”,had better是情态动词;some在变否定句疑问句是要换成any。故填not;any。
28. better not
had better do sth的否定是:had better not do sth“最好不……”,故填better;not。
29. had better not
had better do sth最好做某事,had better not do sth最好不要做某事,故填had better not。
30. can’t draw
句子中有情态动词can,变成否定句,只需在can后加not,后面动词用原形。故填can’t;draw。
31. Does any
此句谓语是情态动词 has to,主语是第三人称单数,改为一般疑问句要借助助动词does,把has to改为have to;some用于肯定句,any一般用于疑问句或否定句中,所以要把some改为any。故答案为Does;(2)any。
32. oughtn’t
to
否定句一般在be动词或者情态动词的后面加not,此处ought to表示“应该”,作情态动词使用,所以在ought后加not,故填oughtn’t to。
33. she would
直接引语是一个陈述句,间接引语应变为that引导的宾语从句,that可以省略;主语I相应地变为she;句中谓语动词said是过去时态,宾语从句中也必须用过去时态,故把一般将来时变为过去将来时。故答案为she would。
34. better not
had better do sth的否定是had better not do sth,意为“最好不要做某事”。故填better;not。
35. not go
固定短语had better do sth.“最好做某事”,改为否定句,在do前面加not即可,故填not;go。
