祈使句用以表達(dá)命令，要求，請(qǐng)求，勸告等。
1) 祈使句有兩種類型，一種是以動(dòng)詞原形開頭，在動(dòng)詞原形之前加do (但只限于省略第二人稱主語的句子)。
Take this seat.
Do be careful.
否定結(jié)構(gòu)：
Don't move.

2) 第二種祈使句以let開頭。
Let 的反意疑問句

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(jié)構(gòu)：
