高中英语语法辅导:反意疑问句特殊情况秀
http://www.sina.com.cn 2004/04/07 20:15  英语辅导报

  大家知道,一般情况下,反意疑问句是由be动词(am, is, are, was, were)/助动词(does, do, did, has, have)/情态动词+主语构成的.当陈述句为肯定结构时,反意疑问句用否定结构.反之,当陈述句为否定结构,反意疑问句用肯定结构.而下面将讲一下反意疑问句的特殊情况,同学们得用心地去记.

  一、当陈述句部分有否定词(never, no, nobody, seldom, nothing, nowhere等)时,反意疑问句要用肯定形式.如:

  He seldom goes home on Sundays, does he?

  二、当陈述句为祈使句时:

  ①如果是肯定陈述句,反意疑问句常用won't you/will you?如:

  Do exercises more carefully next time, won't you/will you?

  ②如果是否定陈述句,反意疑问句通常只能用will you?如:

  Don't do things at the wrong time, will you?

  ③如果陈述句以Let's开头,反意疑问句用shall we?如:

  Let's visit the High Dam, shall we?

  ④如果陈述句以Let us开头,反意疑问句用will you?如:

  Let us go hunting, will you?

  三、当陈述句中有used to时,用did或used构成反意疑问句.如:

  He used to be a famous writer, usedn't he/didn't he?

  四、当陈述句有ought to时,用ought或should构成反意疑问句.如:

  He ought to be praised for what he has done,oughtn't he/shouldn't he?

  五、当陈述句中含有must时,反意疑问句可有多种构成形式:

  ①表示推测时,反意疑问句的构成形式举例如下:

  He must be a visitor, isn't he?(对现在情况的推测)

  You must have seen him at his birthday party yesterday, didn't you?(对过去情况的推测,且句中有过去的时间状语)

  You must have seen him at his birthday party,haven't you?(强调动作的完成)

  ②表示"必须"或"必要"时,其反意疑问句的构成举例如下:

  They must work hard, mustn't they?(必须)

  They must take medical lessons, needn't they?(必要)

  六、当陈述句中有dare, need时,如果是情态动词,用dare, need本身构成反问,如果是实义动词,则用do的适当形式.如:

  He dare climb the mountain, daren't he?

  She dared to walk at night, didn't she?

  You need have a rest, needn't you?

  The house needs to be cleaned, doesn't it?
