祈使句
定义：表示请求、命令、劝告、禁止等的句子叫作祈使句。
读祈使句时一般用降调，句末用句号或感叹号。
结构： 肯定祈使句 ①Do型：动词原形+其他.
②Be型：Be+形容词/名词+其他.
③Let型：Let+宾语+动词原形+其他.
否定祈使句 ①Don’t +动词原形+其他.
②Don’t be +形容词+其他.
③No+名词/动词-ing.
注意：Let 型祈使句否定式：可在let前加don't,也可在let后宾格的后面加not。
例：Don't let her know that.=Let her not know that.
如果是以let's开头的祈使句，必须在let's后加not。
例：Let’s not talk in the library.
3.祈使句解题技巧： 闽教最常考的是Do型和let型祈使句，祈使句无人称和数的变化，后接动词原形。
