must的反意疑问句形式多样

must的反意疑问句形式多样

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。

那么它们的反意疑问句是什么呢?很多同学想当然地写成mustn’t he/you.,这是完全错误的。

当must表推测时,其反意疑问句随时间和人称而变化。

正确的答案应该分别是isn’t he和 haven’t you。

那么如何才能快速准确地做出判断呢?根据笔者多年的教学经验,利用还原法解决这一问题较好。

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 is a teacher.其反意疑问句为isn’t he? 也就是原句的正确答案。

同样方法You must have waited for a long time.可还原为 You have waited for a long time.其反意疑问句haven’t you?即原句的答案。

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, isn’t he?(还原为He is ill at home.)2.They must be ill at home, aren’t they?(还原为They are 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。

must的反义疑问句的用法

must的反义疑问句的用法

must的反义疑问句的用法反义疑问句是英语语法中常用的一种结构,用来构成简短的提问句,通常用于确认或询问说话者所提出的问题是否正确或肯定。

反义疑问句的基本形式为一句肯定句后跟一个含有否定意义的简单问句。

肯定句“You are a teacher”(你是一名教师)可以构成反义疑问句“…, aren't you?”(…,不是吗?)。

否定句“You are not a teacher”(你不是一名教师)可以构成反义疑问句“…, are you?”(…,是吗?)。

而“must”作为情态动词,在肯定句中表示必须要做的事情,否定句中则表示不必或不应该做的事情。

反义疑问句也可以应用在“must”这个词上,它的用法与其他词汇类似,与一般的反义疑问句一样构成。

例如:“You must be very busy with your classes, aren’t you?(你必须很忙于课程,不是吗?)或者,“You must not forget to bring your books, must you?“(你不应该忘记带书,对吧?)下面是关于“must”反义疑问句的详细用法和示例:1. 肯定句 + 简单疑问句当肯定句中使用“must”表示“必须”时,需要添加否定的疑问句来构成意义上的反义。

例如:“I must finish my work before leaving. Mustn't I?”(我得在离开前完成工作,是吧?)2. 否定句 + 简单疑问句当否定句中使用“must”表示“不必”或“不应该”时,需要添加肯定的疑问句来构成意义上的反义。

例如:“You must not be rude to your elders. Must you?”(你不应该对长辈无礼,是吧?)3. 肯定句缩略形式 + 简单疑问句当使用缩略形式的肯定句时,需要将其转换为完整形式来构成反义疑问句。

“You must be joking, aren't you?”(你一定在开玩笑,对吧?)4. 否定句缩略形式 + 简单疑问句当使用缩略形式的否定句时,需要将其转换为完整形式来构成反义疑问句。

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:
①must
②needn't
③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→must
mustn'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?。
