初一英語祈使句結構用法

  

  祈使句用以表達命令,要求,請求,勸告等。

  1*** 祈使句有兩種型別,一種是以動詞原形開頭,在動詞原形之前加do ***但只限於省略第二人稱主語的句子***。

  Take this seat.

  Do be careful.

  否定結構:

  Don't move.

  Don't be late.

  2*** 第二種祈使句以let開頭。

  Let 的反意疑問句

  a. Let's 包括說話者

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

  = Shall we have another try?

  b. Let us 不包括說話者

  Let us have another try,will you / won't you?

  = Will you please let us have another try?

  否定結構:

  Let's not talk of that matter.

  Let us not talk of that matter.
