第2课时 Grammar time(例题讲解)
知识点一 一般过去时
【知识精讲】
一、结构
there be结构在一般过去时的各种句型转换:
There be结构的组成: There be + 名词短语 +方位短语.
(数量词+名词)
肯定句:
e.g.: Long long ago, there was a king.
There were a lot of people in the street.
二、意义
【经典例题】
1.Long long ago, there ____ a boy called Ma Liang.
A. was B. were C. is
2.He pointed at the dog and “Give me the ball.”
A. shout B. shouted C. laugh
【名师解析】
1. 句意:很久很久以前,有一个叫做马良的男孩。Long long ago说明应该用一般过去时; a boy说明用be动词的单数形式,所以选A。
2. 根据pointed 和and可知,横线应该用动词的过去式,所以选B。
知识点二 动词过去式的变化——规则变化
【知识精讲】
【经典例题】
We ______ in HK three years ago.
A. lived B. liveed C.livd
【名师解析】
句意:三年前我们住在相关。live是以不发音的e结尾,它的过去式为规则变化,直接在词尾加d。所以选A。
知识点三 动词过去式的变化——不规则变化
【知识精讲】
【经典例题】
1.I ________ him, but he ________ at home.
A. call; weren't B. called; aren't
C. called; was D. called; wasn't
2.—Where ________ you five days ago?
—I ________ in Beijing.
A. was; were
B. were; was
C. was; was
D. were; am
【名师解析】
1. 句意:我给他打电话,但是他没有在家。两条线的时态应该是一致的,所以排除AB;根据but可知,前后意思为转折,所以选D。
2. 根据ago可知,对话谈论的是过去的事情,所以用一般过去时。you对应be动词的过去式为were, I 对应be动词的过去式为was,所以选B。
知识点四 a lot of
【知识精讲】
一、含义:
许多
二、用法
表示“许多”的意思。a lot of既可接可数名词,也可接不可数名词,多用于肯定句。
a lot of=lots of, 可修饰可数或不可数名词,意为“许多”,“大量的”,相当于many或much。
a lot of与lots of放在修饰的名词前。
There were a lot of people at the party.
有许多人参加聚会。
【经典例题】
You can see _____ animals in the zoo.
A. a lot B. a lots of C. a lot of
【名师解析】修饰可数名词复数形式animals,表示许多,可以用lots of或者a lot of,所以选。
【拓展辨析】
many很多, 修饰可数名词复数;
much 很多, 修饰不可数名词。
