Must的反义疑问句

Must的反义疑问句

Must的反义疑问句:当陈述部分有情态动词must,问句有4种情况:(1)mustn't表示“禁止,不可,不必”时,附加问句通常要用must.You mustn't stop your car here,must you?你不能把车停在这地方,知道吗?(2)must表示“有必要”时,附加问句通常要用needn't.They must finish the work today,needn't they?他们今天要完成这项工作,是吗?(3)当must用来表示对现在的情况进行推测时,问句通常要根据must后面的动词采用相应的形式。

He must be good at English,isn't he?他英语一定学得很好,是吗?(4)当must+have done表示对过去的情况进行推测(一般句中有明确的过去时间状语),问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”;如果强调动作的完成(一般没有明确的过去时间状语),问句要用“haven't/hasn't+主语”。

She must have read the novel last week,didn't she?她上星期一定读了这本小说,是吗?You must have told her about it,haven't you?你一定把这事告诉她了,是吗?need的反义疑问句:need的用法分为两种,一种是作为情态动词,一种是作为实义动词。

一般而言,need作为情态动词是在否定句(有时为疑问句中),此种情况在反义疑问句中通常为need I或needn't I,而当这句话是一句肯定句是,这里的need就作为实义动词,通常为do you或者是don't you就比如LZ说的句子I needn’t tell you the answer , need I ?这里need为情态动词,前面否定,后用need肯定You need to buy a better dictionary , don’t you ? 这里need为实义动词,前面肯定,所以后面用do的否定形式don't说起will,我不明白LZ是什么意思,与will有关的知识点整理在这里开头为Let's,后面一定用shall +we例:Let's go,shall we开头为Let us,后面一定用will you例:Let us go,will youthink, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时,视情况不同有两种不同的构成方式。

must 的三种反义疑问句

must 的三种反义疑问句

must 的三种反义疑问句既然多数人感到麻烦我就来讲一讲must反义疑问句的用法。

你记住,must反义疑问句就三种可能:①must②needn't③变换句式下面来讲一讲他们分别的用法,一般考试就这三种可能!1、mustn't→mustmustn't在陈述句中的意思一般是不允许,禁止,所以他的反义疑问句用must或may例:You mustn't smoke here, must you?或may you?2、必须→needn't当must在陈述句中作“必须”解时,它的反义疑问句就变成needn't例:You must go now ,needn't you?3、变换句式在must表示推测,做“一定,准是”,简单的说就是must用于虚拟语气时像数学一样我们引入一个“常量”——I am sure that下面就能你那句话作为例子,我们变换一下。

He must have come yesterday. 变换句式作I am sure that he came yesterday. 好我们应该分清,反义疑问句问的应该是I am sure that 后面的从句所以,按照一般反义疑问句的规则得出结果I am sure that he came yesterday, didn't he?最后再把句子还原He must have come yesterday,didn't he?此题解答完毕。

下面是我搜索英国和美国语料库的结果:英国语料库:Davies, Mark. (2004-) BYU-BNC: The British National Corpus. Available online at /bnc.1.

利用还原法巧解must的反意疑问句

利用还原法巧解must的反意疑问句

利用还原法巧解must的反意疑问句:must + be/do可以表示对目前情况的肯定推断如:He must be a teacher, _________?. 他一定是一位老师。

must + have done可以表示对过去情况的推测,如:You must have waited for a long time,_______________?.你一定已经等了很长时间了。

所谓还原法,就是先把句子还原成一个不带must推测意味的句子。

如He must be a teacher.可还原为He _______ a teacher.You must have waited for a long time.可还原为You _______for a long time.注意:1、在must 表示现在情况的推测时,要注意主语对还原后句子谓语动词的影响。

如:1.He must be ill at home, ________ he?(还原为He ____ ill at home.)2.They must be ill at home, ______ they?(还原为They _______ ill at home.)2、must 表示对过去的情况推测时,要注意句意和时间状语对还原后句子时态的影响。

如含有for a long time, so far, before, since 等时间状语的句子还原后句子为完成时;而含有last night, yesterday, the other day, ten years ago 等时间状语的句子则还原为过去时。

如:He must have seen her in the street yesterday, _____ he?(还原为:He ____ her in the street yesterday.)He must have learned English for more than 10 years,______ he?(还原为:He ________English for more than 10 years.)你能完成下列练习吗?1.She must have a big family,______ ?2.You must be tired,_________ ?3.It must have rained last night,______ ?4.You must have had a good time at the party, _______?5.His wife must have misunderstand him at that time,_________ ?6.He must have read the novel before,______ ?7.They must have lived there since then, ______?8.The boy must be playing computer games in his room now,__________ ?。

must have done的反义疑问句

你好^^
情态动词+动词完成时,即情态动词+have+done.表示对过去的行为或动作进行
推测,评论或者判断.
1.must have done.
表示对过去某事的肯定猜测,其否定或疑问形式都用can/could来表示。

例如:since the road is wet,it must have rained last night.
2;当然对现在发生或者将来发生的事情,要用must do表示猜测,否定为can‟t do
he must understand that we mean business.
you must be hungry after a long walk.
反意疑问句中含有Must的情况主要有以下几种:
1)作为情态动词表“必须”,这时反意疑问句直接用mustn'/needn't
2)当must表示推测时又分以下几种情况:
a:对现在事实的推测,反意疑问句与must后面的动词呼应,如:
You must be joking,aren't you ?
b:对过去事实的推测,表示动作的时候用did 当助动词,表示状态时用was,如:Mr Green must have been punished for his being rude at the meeting,didn…t he ?(格林先生一定因为昨天在会上鲁莽的行为被处罚了,是吗?)被处罚表示一个动作
She must have been a policeman ,wasn't she ?(她过去一定是个警察,是吗?)是警察表示一种状态
对现在情况的推测,问句部分用主动词(do,be)一般现在时的适当形式。

若是现在进行时,问句部分用现在进行时的适当形式表示。

若是there be结构,问句用isn't/aren't there。

如:
1)He must be there,isn't he?
2)He must have a big family,doesn't he?
3)He must be waiting outside,isn't he?
4)There must be some students in the room,aren't there?
对已发生的过去情况的推测,若陈述句谓语部分有“must have done”,而且有表示过去的时间状语,问句部分用didn't;若没有表示过去的时间状语,问句部分用haven't或hasn't。

如:
1)They must have gone there last night,didn't they?
2)They must have arrived by now,haven't they?(根据by now来判断)
3)They must have been to the Great Wall,haven't they?
若是被动,应按被动结构来处理。

如:
1)The room must have been cleaned yesterday,wasn't it?
2)The room must have been cleaned,hasn't it?
若句中有表示过去完成时的时间状语,问句部分应用hadn't.如:
They must have learnt 5000 English words by the end of last term,hadn't they? (本题中must表推测,如果将它去掉,还原为真实句就是They had learnt 5000 English words by the end of last term.因此,反意问句是hadn't)
希望能帮到你。

嘿嘿,给我分成不成~~~~。
