初中英语一轮复习

初中英语八大时态

教学重、难点:

1、The Simple Present Tense 一般现在时态

一般现在时
表示经常发生的动作或存在的状态 常与every day , on Sundays, sometimes , often ,usually ,always,等连用 结构 : 1、主语+动词原形+其他 Eg. 1) I have a meeting on Sundays . 2) They visit their parents once a month.

注: 主语(三单)+ 动词(第三人称单数形式)+其他
Eg. 1) She likes it very much. 2) She usually goes to school at 7 o’clock every morning.

动词第三人称单数形式

· 在以s,x,ch,sh,o结尾的动词+es · 以辅音字母+y结尾的动词,
先变y 为i,再加es · 特殊 have-has 等

· 在动词后+s

写出下列动词的第三人称单数形式
help s guess es ies fly makes leaves fix es swim s know s play s closes go es ies study gets read s bring s watch es carry ies do es wash es visit s exercise s enjoy s jump s have has

一般现在时否定式

be + not don’t do / doesn’t do

II 一般现在时的否定式
1.Be 动词的否定式: be + not
I am a teacher. I’m not a teacher

You are a worker 否定句 She is a doctor We are friends.

You aren’t a worker
She isn’t a doctor.

We aren’t friends.

is not=isn’t

are not=aren’t

2. 当主语是单数第三人称时, 它与助动词 Does 有关,但是 动词谓语一定要恢复为原形。 当主语是其他人称时,它与 助动词Do有关。
I like English. She likes it very much. We go to work by bike. I don’t like English.

否定句

She doesn’t like it very much.
We don’t go to work by bike.

III一般疑问句
概念:用 yes 或 no 来回答的疑问句叫做一般疑问句。 一般疑问句句首的第一个词一般读得比较重。

1.对于be 动词,疑问句要求把be 提前, 第一人称变成第二人称。

I am a teacher.
疑 You are a worker. 问 句 He is a student.

Are you a teacher?

Are you a worker?

We are friends.

Is he a student? Are you friends?

2.对于实意动词,疑问句要求是:当主 语是他(he),她(she),它(it)时,句子前 面加does,并把动词恢复原形;当主语 是其他人称时,句前加do ,第一人称 (I/we) 换第二人称(you)。
I often go there. You like the music. He goes to work by bus . We /You/They like it. Do you often go there ?

Do you like the music.?
Does he go to work by bus ?
