1. 祈使句的概念 祈使句表示请求、命令等。它的主语是yu（听话人），通常不说出。祈使句肯定结构中的谓语动词一律用动词原形。祈使句末用惊叹号或句号，句子用降调。 2. 祈使句的结构 1) 祈使句的肯定结构 ① D型（以行为动词原形开头），例如： Sit dwn!坐下！ Stand up!起立！
② Be型（以be开头），例如： Be quiet!安静！ Be careful！小心！③ Let型（以let开头），例如： Let me try. 让我试试看。 Let’s lk at the map. 让我们看看地图。● let’s是let us的简略式。
● 表示请求、劝告的祈使句还常常在句前或句末加上please, 构成句式：Please …或 …, please. 以使语气更加缓和或客气。例如： Please stand up. 或 Stand up, please. 请站起来。 Please have a rest. 或Have a rest, please. 请休息一下。
2) 祈使句的否定结构，一律在肯定结构前加 D nt (Dn’t)。例如： Dn’t g there, please. 请别去那儿。Dn’t be late fr class! 上课别迟到！Dn’t let him in. 不要让他进来。
