以下是©無(wú)憂考網(wǎng)為大家整理的關(guān)于小學(xué)四年級(jí)英語(yǔ)語(yǔ)法輔導(dǎo)：祈使句結(jié)構(gòu)的文章，希望大家能夠喜歡！
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(lèi)型，一種是以動(dòng)詞原形開(kāi)頭，在動(dòng)詞原形之前加do (但只限于省略第二人稱(chēng)主語(yǔ)的句子)。

Take this seat.

Do be careful.

否定結(jié)構(gòu)：

Don't move.

Don't be late.

2) 第二種祈使句以let開(kāi)頭。

Let 的反意疑問(wèn)句

a. Let's 包括說(shuō)話者

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

= Shall we have another try?

b.　Let us 不包括說(shuō)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)：

Let's not talk of that matter.

Let us not talk of that matter.
