1.祈使句
祈使句是用来表示请求、命令、建议等的句子。祈使句通常省略主语,直接以动词原形开头。例如:Sweep the floor.扫地。句子中没有出现主语you.
在实际对话中,祈使句可以加上对对方的称呼,明确指令的针对性;还可以加上表示礼貌的please(请)。
例如:Sam, sweep the floor, please.萨姆,请扫一下地。
Please clean your desk and chair, Max.马克斯,请把你的桌椅擦干净。
在祈使句中加上please,可以让请求或命令的语气变得更加温和、有礼貌,避免给人一种强硬的感觉,表达对对方的尊重,显示出说话者的良好素养。
2. let's的用法
(1) let's引导的祈使句基本句型结构为:Let's+动词原形(+其他)。,意为“让我们做某事”。let's是let us的缩略形式,表示“让我们⋯⋯”。us是we的宾格。
例如:Let's go to school.让我们去上学吧。
Let's take some pictures.让我们拍一些照片吧。
(2) 对“Let' s…”的常用肯定回答有: OK./ All right./ Good idea.
3. clean的用法
(1) clean可以作动词,表示“打扫,清洁”。
例如:clean the blackboard擦黑板
clean your bedroom打扫你的卧室
(2) clean也可以作形容词,表示“洁净的,干净的”。
例如:a clean desk一张干净的课桌
keep your desk clean保持你的课桌干净
