小学四年级英语:My Schoolbag——There be 句型与方位介词

小学四年级英语:My Schoolbag——There be 句型与方位介词

一、本课知识点

四年级英语上册 Unit 2 的话题是 My Schoolbag(我的书包)。这一课有两个核心:用 There be 句型说"某处有某物",用方位介词说清东西在哪儿。

  1. 核心单词(先认后写) schoolbag 书包 maths book 数学书 English book 英语书 Chinese book 语文书 storybook 故事书 notebook 笔记本 candy 糖果 toy 玩具 key 钥匙 pencil box 铅笔盒

  2. There be 句型 结构:There is + 单数 / There are + 复数。 There is a storybook in my schoolbag. 我的书包里有一本故事书。 There are three books on the desk. 桌子上有三本书。 口诀:"单数 is,复数 are,就近一致不能忘。" 当句子里第一个名词是单数时用 is,是复数时用 are: There is a pen and two books on the desk. There are two books and a pen on the desk.

  3. 方位介词 in 在……里面 on 在……上面 under 在……下面 near 在……附近 behind 在……后面 beside 在……旁边 in front of 在……前面

  4. 常用问答 —What's in your schoolbag? 你的书包里有什么? —I have a maths book, two notebooks and a pencil box. —Where is my key? 我的钥匙在哪儿? —It's under the chair. 在椅子下面。 —Where are the candies? —They're in the box.

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

  1. There is 后面接复数名词是错的。书包里有两本书,必须用 There are。
  2. 名词单复数。two notebook 应写 two notebooks;three key 应写 three keys。
  3. 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.
  4. 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。
  5. 拼写注意 schoolbag 是一个词,pencil box 是两个词。

四、分层练习

基础题 英汉互译 1. 书包 __ 2. 故事书 _ 3. 在椅子下面 ___ 4. 在桌子上 __ 5. There are two notebooks ____

提高题 选择填空 6. There _ a pencil and two books in the bag. A. is B. are C. be (答案:A) 7. —Where _ my keys? —They are on the sofa. A. is B. are C. am (答案:B) 8. The ball is ____ the bed. We can't see it. A. on B. under C. in front of (答案:B)

拓展题 小练笔 9. 用 There is / There are 和方位介词,写5句话介绍你的书包。 参考范文: This is my schoolbag. It's blue and white. There is a Chinese book and a maths book in it. There are two notebooks and a pencil box in it, too. My keys are under the books. I like my schoolbag very much.

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。
