  初中英语语法大全:祈使句结构

  13.1 祈使句结构

  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.
