【編輯寄語】以下是©無憂考網(wǎng)為大家整理的《小學(xué)四年級(jí)英語語法總結(jié)：祈使句結(jié)構(gòu)》，供大家參考！
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.
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(jié)構(gòu)：
Let's not talk of that matter.
Let us not talk of that matter.
