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.
