二、句型操练与例题
例题1 用 is / are 填空。 1. There _ a Chinese book in the desk. (答案:is) 2. There two keys in the pencil box. (答案:are) 3. There _ a toy and three books on the bed. (答案:is,就近一致) 4. There three books and a toy on the bed. (答案:are)
例题2 根据提示回答问题。 A: Where is the schoolbag? B: ___ (提示:在桌子下面) 参考答案:It's under the desk. A: What's in it? B: ___ (提示:一本故事书和两本笔记本) 参考答案:There is a storybook and two notebooks in it.
例题3 连词成句。 1. is, there, a, my, in, candy, bag (.) 参考答案:There is a candy in my bag. 2. books, are, the, on, there, desk, three (.) 参考答案:There are three books on the desk.
三、易错点提醒
- There is 后面接复数名词是错的。书包里有两本书,必须用 There are。
- 名词单复数。two notebook 应写 two notebooks;three key 应写 three keys。
- 回答 Where 的问句不能用 There is...,要用 It's... / They're...。 正确:—Where is the key? —It's on the desk.
- in 和 on 别混:东西装在里面用 in,放在表面用 on。书在书包里用 in,书在桌面上用 on。
- 拼写注意 schoolbag 是一个词,pencil box 是两个词。
四、分层练习

五、小结
这一课只做三件事:记住10个单词,说对 There is / There are,用对 in、on、under。每天大声读三遍例句,再把教室里的东西用英语说一遍,一周之后这两组句型就能自然说出口。
