2015年公共英语考试辅导:祈使句结构
发布时间:2011/11/23 5:43:01 来源:城市学习网 编辑:moon

  祈使句用以表达命令,要求,请求,劝告等。

  1) 祈使句有两种类型,一种是以动词原形开头,在动词原形之前加do (但只限于省略第二人称主语的句子)。

  Take this seat.

  Do be careful.

  否定结构:

  Don't move.

  Don't be late.

  2) 第二种祈使句以let开头。

  Let 的反意疑问句

  a. Let's 包括说话者

  Let's have another try,shall we / shan't we?= Shall we have another try?

  b. Let us 不包括说话者

  Let us have another try,will you / won't you?= Will you please let us have another try?

  否定结构:

  Let's not talk of that matter.

  Let us not talk of that matter.
