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.
