Don’t be late for school! 上学不要迟到! 2.Let型的否定式有两种:“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”。如:Don’t let him go./ Let him not go.别让他走。 3.有些可用no开头,用来表示禁止性的祈使句。如:No smoking! 禁止吸烟!No fishing! 禁止钓鱼!

Grammar focus: Imperatives 祈使句 2.表示“间接命令”或“愿望”。 这个句型里的动词宾语是第三人称名词或代词,如: (1)Let Robert take charge of the marketing department. (2)Let her join our choir. 3.表示“警告”“蔑视”“威胁”等。 这种祈使句里的宾语也是第三人称为主,除了口气凶悍之外,有时还带讽刺语气,如: (1)Let him try and he will expose his inability to work on his own.
