仁爱7年级上 Unit2 Topic 3 Section A学案

一. 学习内容

1玛丽和康康的对话，学习物主代词。 2操练形容词性物主代词和名词性物主代词。 二、学习要求 1.必会主要生词和短语

Mine, whose, then, bike, cat, banana, its, our, food, bag 2.必会主要句型

Whose cap is it, then? It’s Sally’s.

Whose bike is this? It’s his bike./It’s his.

三、本节课的学习要点及考点 1.Whose cap is it, then? 那么这是谁的帽子呢?

Whose 这是一个特殊疑问词, 意思是谁的， 回答时用形容词性物主代词,名词性物主代词或名词所有格回答. Whose bike is this? It’s his bike. /It’s his. It’s Li Ming’s.

2.It’s Sally’s. 是萨利的。

名词所有格一般在词尾后直接加’s. 以s结尾的直接加’. 如:Mike’s cap, Dennis’ book. 3.Whose bike is this? It’s his bike./It’s his.

第一个是形容词性物主代词, 第二个是名词性物主代词

物主代词实际上是人称代词的所有格形式。根据其句法作用，物主代词可以分为形容词性和名词性两种。形容词性物主代词一定要后接名词（如：This is my book. 这是我的书。），名词性物主代词可以独立使用，无需后接名词（如：This book is mine. 这本书是我的。）。

数 单数 复数 人称 第一人称 第二人称 第三人称 第一人称 第二人称 第三人称 形容词性my 物主代词 your His/ her/its our your their 名词性物mine 主代词 yours His/ hers/ its ours yours theirs 3． whose的中文意思是谁的，是引导特殊问句的疑问词，常对名词性物主代词、 形容词性物主代词及名词所有格形式进行提问。whose与who's是同音词，但用法

不同，whose可单独使用，也可与名词连用，表示―谁的……东西‖，而 who's=who is （是谁）。Whose在句中的用法举例如下：Whose is this coat? Whose shoes are they?

. Whose blouse is this?这是谁的衬衣？Whose shoes are these?这些是谁的鞋？（1）对名词性物主代词及不接名词的所有格提问时，whose常单独充当特殊疑问 句词。如：1)The brown shoes are his. ---- Whose are the brown shoes?2)That blouse is Kate's.---- Whose is that blouse/（2）对形容词性物主代词和后接名词所有格提问时，whose后必须加名词或充当

疑问词，不能单独使用。如：1)It is Jim's pen.---- Whose pen is it?2)Those are Mr Green's trousers. ----Whose trousers are those? 典型例题：

1.Those are your shoes.(改为同义句) ________________.

2.This is his food. (改为同义句) __________________.

答案：1 Those shoes are yours.

2.This food is his.

研析：名词性物主代词等于形容词性物主代词加名词。 四、学习过程

（一）课前预习 1.课前预习课本P41—42.

2. .课前预习 同步练习与测试 Unit 2 Topic 3 Section A练习 3.做一做

1．Whose bike is this? It’s ____ bike. It’s his.

2.Whose banans are these? They are its bananas. They are ______. 3.Whose apples are these? They are ______ apples. They are theirs. 4._____ toys are those? –They are your toys. They are _______. 1.his 2.its 3.their 4.Whose, yours. （二）.课堂探研

名词性物主代词和形容词性物主代词的区别？

物主代词可分为形容词性物主代词和名词性物主代词。

1. 形容词性物主代词起形容词的作用，作前置定语，用在名词前。 例： 1) This is my book. 这是我的书。

2) We love our motherland. 我们热爱我们的祖国。

2. 名词性物主代词起名词的作用。名词性物主代词= 形容词性物主代词+名词 例: 1) Look at the two pencils. The red one is yours and the blue one is mine. = The red one is your pencil and the blue one is my pencil.

看那两支铅笔，红的是你的，蓝的是我的。 2) He likes my pen. He doesn’t like hers. = He doesn’t like her pen. 他喜欢我的钢笔。不喜欢她的。

3. 注意：在使用名词性物主代词时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提起过。

例： It’s hers. 是她的。 （单独使用大家不知是怎么回事，不可以这样用） There is a book. It’s hers. 那有本书。是她的。 （先提及，大家才明白） 4. 名词性物主代词=形容词性物主代词+名词

为避免重复使用名词，有时可用―名词性物主代词‖来代替―形容词性物主代词+名词‖的形式。 例：

My bag is yellow，her bag is red，his bag is blue and your bag is pink. 物主代词为避免重复使用bag，可写成My bag is yellow，hers is red，his is blue and yours is pink.

名词性的物主代词在用法上相当于省略了中心名词的 --’s属格结构。 例如： Jack’s cap 意为 The cap is Jack’s. His cap 意为 The cap is his.
