Grammar Focus
祈使句
用于表达命令、请求、劝告、警告、禁止等的句子叫祈使句。
祈使句最常用于表达命令，因其对象(即主语)是第二人称，所以通常省略主语而以动词原形开头。
祈使句句末使用句号或叹号来表示结束。
为表示礼貌，可在句首或句末加上 please。please 放在句末时，其前面通常加逗号。
e.g. Go and wash your hands. 去洗手。
命令
e.g. Look out! Danger! 小心！危险！
强烈警告
e.g. Be quiet, please. 请安静。
请求
祈使句的形式
肯定祈使句的形式:
Do型
Be型
Let 型
动词原形 (+宾语) +其他成分.
Be+表语(名词或形容词)+其他成分.
Let+宾语+动词原形+其他成分.
e.g. Please have a seat here. 请这边坐。
e.g. Be a good child!
要做一个好孩子！
e.g. Let me help you.
让我来帮你。
否定祈使句的形式：
Do型和Be型祈使句的否定式都是在句首加don't(若句首有please,则在 please 后加 don't)。
e.g. Don't forget me! 不要忘记我！
Please don't be late for school! 请不要上学迟到！
Let 型祈使句的否定式有两种："Don't +let +宾语+动词原形+其他成分."和"Let +宾语 +not+动词原形 +其他成分."
e.g. Don't let him go. /Let him not go. 别让他走。
用no开头，表示禁止的祈使句。
