Alice, please take a raincoat. 爱丽丝，请带上雨衣。 用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句因对象（即主语）是第二人称，所以通常都省略。 例句：请坐！ Sit down, please! 拓展：一般祈使句的否定句有以下3种形式 （1）Don’t+动词原形 Don’t make any noise.不要制造噪音。 （2）No+动词ing No smoking!禁止吸烟！ （3）No+名词 No photos！禁止拍照！ 以Let 开头的祈使句表示建议，构成形式为“Let+宾语+动词原形”。本句“Let’s” 为“Let us” 的缩略形式。 例句：咱们去购物吧。 Let’s go shopping! 2. Let’s take out our raincoats! 咱们把雨衣拿出来吧。 拓展：以Let 开头的祈使句的否定形式是在Let前加 Don’t或在动词前加not。 如：不要让她在墙上乱写。 Don’t let her write on the wall. 3. Let’s put them on. 让我们穿上吧。 put on “穿上、戴上”，强调“穿”“戴”的动作， 后接衣服、鞋帽等。 例句： 孩子们穿上了一些暖和的衣服。 The children put on some warm clothes. 拓展：如果后面是人称代词的宾格形式，则人称代词 的宾格形式放在put 与on之间。 Homework 1.熟读 page20的课文。 2.练习短语：in the sky take a raincoat take out put on make a house play with me poor thing Thank you!
