祈使句一、定义： 祈使句表达说话人对对方的叮嘱、劝 告、希望、禁止、建议、请求或命令等。 二、祈使句的特征： 以动词原形开头，无时态和数的变化。

三、祈使句的句型： 1. 动词原形构成的祈使句 通常省略主语 you,谓语动词用原形。 否定句由 don’t 或 never 开头。祈使句 的句首或句末有时加 please。 2. let 构成的祈使句 由“Let + me/us/him/her + 动词原形” 构成。这类祈使句往往用于请求允许 (let us)或提出建议(let’s)。

例如： Let’s spend this weekend in the countryside. Let him be here by ten o’clock.

3. 无动词祈使句 在请求，命令和口号中，常用无动词祈 使句，它实际上是省略了动词，从而使语 句更简洁有力。

例如： Just a minute, please! 在一些指示牌上，常用“No + 动名词/ 名词”构成省略的否定祈使句。 例如：No smoking!
