祈使句 (Imperative sentences) 一、含義
祈使句一般用來(lái)表示請(qǐng)求、命令、勸說(shuō)、號(hào)召、警告等。在祈使句中，通常省略主語(yǔ)yu，其肯定形式常以動(dòng)詞原形開頭，否定形式是在動(dòng)詞原形前加dn’t。祈使句句尾用句號(hào)或感嘆號(hào)，讀時(shí)用降調(diào)。為表示禮貌，可以在句首或句末加上please。句末用please時(shí)，前面通常加逗號(hào)。
1. D型祈使句肯定句：實(shí)義動(dòng)詞原形(+賓語(yǔ))(+其他).否定句：Dn’t +實(shí)義動(dòng)詞原形(+賓語(yǔ))(+其他).Remember t smile all the time. 記得要一直微笑。Dn’t smke here ! 不要在這里抽煙!

3. Let型祈使句Let’s have a rest.咱們休息一下吧。Dn’t let them make any nise. 不要讓他們發(fā)出任何噪聲。Let’s nt say anything abut it ! 這事咱們什么也別說(shuō)！
