祈使句

当我们向他人发出命令，提出要求或建议时，常使用祈使句。祈使句的祝愿时you（听话人），通常不明

确表示出来。

句式结构例句

D。型：动词原形（+宾语）+其他成分。Haveaseathere.这边坐。

肯定句Be型：Be+n/adj+其他成分。Beagoodchild!要做一个好孩子！

Let型：Let+宾语+动词原形+其他成分。Letmehelpyou.让我来帮你。

Do型和Be型均在句首加Don't构成。Don'tbelatefbrschool!上学不要迟到！

Let型的否定形式有两种：Don'tlethimgo.

否定句

Don，t+let+宾语+动词原形+其他成分。=Lethimnotgo.

Let+宾语+not+动词原形+其他成分。

祈使句+willyou/won'tyou?Openthewindow,willyou?

Letus不包括听话者在内，指示对听话者Letusplaywithsnow,willyou?

反义疑问句说，反义疑问句的主语仍然为you让我们玩雪，好吗？

Let's是表示第一人称的祈使句，包含说Letusplaywithsnow,shallwe?

话者，所以反义疑问句的主语为we.咱们玩雪吧，好吗？

派（1）有的祈使句在意思明确的情况下，动词可省略。

Thisway,please.=Gothisway,please.

（2）有些祈使句可用No开头，用来表示禁止。

Nosmoking噤止吸烟！

（3）为了使祈使句听来比较客气，委婉，除了用please外，句末还可用willyou。

Readthetext,willyou?读一下这篇文章，好吗？

(4)在祈使句的前面加上do可以加强语气，有makesure(一定，务必)的意思。

Doremembertocallme.

(5)祈使句的答句常用一般将来时。

一Don'tsmokehere.

—Sorry,!won't.
