Unit 2 语法易错+巩固练习（导学案）三年级英语暑假自学课（人教PEP版·新教材）

人教PEP版新三年级暑期自学课 Unit 2 Different families 语法易错+巩固练习 语法易错01 语法点拨：指示代词this与that 一、定义: this 和 that 均为指示代词，this 意为 “这个”，that 意为 “那个”。 二、用法： 1. 区分距离远近： ①当用于询问距离较近的人物时： —Is this your +家庭成员词汇? —Yes,it is./No,it isn't. ②当用于询问距离较远的人物时： —Is that your +家庭成员词汇? —Yes,it is./No,it isn't. This is an apple. That is a banana. 近 远 2. 介绍他人时把某人介绍给另一个人时，常使用 This is ...，不用 That is ...。 例：Jack, this is my friend, Tom. 杰克，这是我的朋友，汤姆。 3. 打电话时，介绍自己要用 This is...。询问或确认对方时，可以说 Who's that? / Is that...?。 例：—Hello! This is Mike. Is that Mary? 你好！我是迈克。是玛丽吗？ 回答：—Yes, it is. 是的，我是。 三、this 和 that 作主语的一般疑问句 问句：Is this your brother? / Is that your aunt? 肯定回答：Yes, it is. 否定回答：No, it isn't. 注意：在回答 this 或 that 作主语的疑问句时，要用 it 代替 this 或 that。 拓展： （1）肯定句变一般疑问句：只需要把 be 动词提前。 This is an apple. → Is this an apple? That is a banana. → Is that a banana? （2）缩写规则：This is 不能缩写，That is 可以缩写为 That's。 例：This is my brother. 这是我的哥哥。 例：That's an apple. 那是一个苹果。 知识演练一 一、单项选择。 ( ) 1．—Is that a pencil? —________ A．Yes, it is.
