祈使句的否定句怎样构成？肯定句呢？
祈使句的否定句在动词原形前加dn’t，表示“不要做什么事”。
祈使句的肯定句通常是以动词原形开头的。

祈使句一般用来表示请求、命令、劝说、号召、警告等。在祈使句中，通常省略主语yu，其肯定形式以动词原形开头，否定形式是在动词原形前加dn’t。祈使句句尾用句号或感叹号，读时用降调。为表示礼貌，可以在句首或句尾加上please。句末用please时，前面通常加逗号。
肯定句：动词原形 (+宾语)+其他. 否定句：Dn’t+动词原形 (+宾语) +其他.Wear the schl unifrm n weekdays, please. 上学日请穿校服。Dn’t watch TV befre dinner. 晚饭前不要看电视。

情态动词have t与must
二者均可表示“必须”，其后均接动词原形。It’s t late. I have t take a taxi. 太晚了，我必须乘出租车。I must g nw. 我必须现在就走。

have t与must的不同点
He has t leave schl because his family is pr. 因为家里穷，他不得不退学。(受客观因素影响)We must d smething abut it. 关于这件事我们必须做点什么。(责任感的驱使)
