回复:七年级英语期末综合复习
七年级期末综合 复习 (四)
时态复习
一、一般现在时
1、Be 动词的一般现在时
Be动词要根据句中主语的人称和数而变化。它有三种形式:am, is , are
am跟在I后面, is 跟单数主语,are跟复数主语及单数You后面。如:
I am a teacher.
My brother is at school. Lucy and Lily are in Class One, Grade Two.
You are a good boy.
2、
实义动词的一般现在时
一个动作经常反复地发生,就用一般现在时。第三人称单数(he, she , it, Tom等)作主语,谓语动词要加 ″s″ 或 ″es″,但当句中出现does,doesn’t要用原型其它人称用原型。如:
They get up at six o’clock.
He goes to school at seven- thirty .
附:动词第三人称单数的构成规则
1)一般情况下加s
get—gets
like---likes
2)以s, x, ch, sh, o结尾的加es: watch---watches
go---goes
do---does
3)以辅音字母加y结尾的,改y为i,加es
carry---carries
特殊:
have---has, dictionary , strawberry , tomato , photo , documentary, comedy. Beinjing Opera 和 broccoli没有复数形式.注意unit 7中的复数名词的用法,a pair of shorts/sockes/shoes/trousers/pants…复数在pair上加s
二、情态动词can
情态动词(can, may, must )后动词用原形。如:
I can play the guitar.
He can play the violin. 注意:play chess中间不加the
三、几个动词的用法:
1、let后用动词原形
Let’s play soccer.
2、like及介词后动词用ing形式, 如:be good at swimming,
help kids with singing,
like playing basketball,
What about playing tennis?
3、want加 to 再加原形
4、help +人+动词原形
help+人+with sth /doing sth.
5、Like/love to +动词原形 ;like/love +动词ing ; like/love + sth(直接跟名词).
Exercises:
二、完成句子。
1.
I _________ (know) the boy.
2.
They __________(go) to work on Saturdays.
