祈使句用以表达命令,要求,请求,劝告等。
1) 祈使句有两种类型,一种是以动词原形开头,在动词原形之前加do (但只限于省略第二人称主语的句子)。
Take this seat.
Do be careful.
否定结构:
Don t move.
Don t be late.
2) 第二种祈使句以let开头。
Let 的反意疑问句
a. Let s 包括说话者
Let s have another try,shall we / shan t we?
= Shall we have another try?
b. Let us 不包括说话者
Let us have another try,will you / won t you?
= Will you please let us have another try?
否定结构:
Let s not talk of that matter.
Let us not talk of that matter.
