That’s my activity book. Is this your ruler, Jim? Yes, it is. Remember to put your things away after class. OK, we will. Language points 1. Don’t leave your things like this. 不要把你们的东西这样放。 (1)此句为否定祈使句，用来提醒或警告别人不要做某事。don’t是 do not的缩写形式，意为“不要，别”。否定祈使句的结构是：Don’t + 动词原形 + 其他. 例句：Don’t open the activity book. 不要把活动手册打开。 (2)我们以前学过like的意思是“喜欢”，但本句中like的意思是“像；如同”，常构成短语look like…(看起来像……)。 例句：You can draw pictures like this. 你可以像这样画。 2. Put them away. 把它们收起来。 这是一个以动词原形开头的Do型祈使句。祈使句的主语通常为第二人称(you)，但一般都被省略，所以用于祈使句句首的动词总是用原形，不能用其他形式。句型结构为：动词原形 + 其他. 例句：Come here.到这里来。 Open the book, please.请打开书。 拓展：Do型祈使句的用法口诀： Do型祈使句，它的主语（you）常省去； 表示请求或命令，加上please表客气； 如果变成否定句，使用don’t是规律。 3. —Is this your schoolbag? 这是你的书包吗？ 这是以be动词开头的一般疑问句，用来询问近处物品是否是某人的。 句子结构为：Is this +形容词性物主代词/名词所有格+名 词（单数）? 肯定回答是“Yes, … is.” 否定回答是“No, … isn’t.” (your, his, her…) (Lily’s , my mother’s…) 形容词性物主代词 名词所有格 例句：这是你的蜡笔吗？ —Is this your crayon? 不，不是。 —No, it isn’t.
