Unit 2 We're Family

语法+课堂练习+回家作业+答案解析

 

核心语法：实义动词一般现在时(含第三人称单数) + 名词性物主代词

一、实义动词一般现在时

1. 基本规则

- 主语非三单：用动词原形

- 主语是三单：动词用第三人称单数形式

2. 三单变化规则

情况	变化	例词
一般情况	+s	like→likes, play→plays
以s/x/ch/sh/o结尾	+es	pass→passes, watch→watches
以辅音+y结尾	变y为i+es	study→studies, family→families
特殊变化	have→has	He has a dog.

3. 句型结构

句型	非三单	三单
肯定句	主语 + 动词原形	She likes music.

否定句	主语 + don't + 动词原形	He doesn't like coffee.
疑问句	Do + 主语 + 动词原形?	Does he play soccer?

二、名词性物主代词

形容词性物主代词	名词性物主代词	用法	例句
my	mine	相当于"my + 名词"	This pen is mine. = This is my pen.
your	yours	相当于"your + 名词"	Is this book yours?
his/her/its	his/hers/its	相当于"his/her/its + 名词"	The bag is hers.
our/your/their	ours/yours/theirs	相当于"our/your/their + 名词"	These are ours.

课堂练习

语法点1：实义动词一般现在时（含三单）

一、基础题

（ ）1.Tom ______ football every afternoon.
A. play B. plays C. playing D. to play
答案：B
解析：考查实义动词三单，主语Tom是第三人称单数，一般现在时中动词play变三单为plays。

二、培优题

（ ）1.—______ your parents ______ TV in the evening? —Yes, they do.
A. Do; watch  B. Does; watch  C. Do; watches  D. Does; watches
答案：A
解析：考查实义动词一般现在时的一般疑问句，主语your parents是复数，用助动词Do，后接动词原形watch。

三、易错题

（ ）1.My mother ______ not like coffee. She likes tea.
A. do B. does C. is D. are
答案：B
解析：考查实义动词的否定句，主语my mother是三单，否定需用助动词doesn't，后接动词原形；易错点：误选C，混淆实义动词与be动词的否定结构（实义动词需加助动词，be动词直接加not）。

（ ）2.He ______ a new bike. His sister ______ two new bikes,
