must的三种反义疑问句.doc

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：mustneednt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、mustntmust mustnt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 mustnt smoke here, mustyou?或may you?2、必须neednt 当must在陈述句中作“必须”解时，它的反义疑问句就变成neednt例：You must go now ,neednt 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, didnt he?最后再把句子还原He must have come yesterday，didnt 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.
