初中英语八种时态归纳复习
时态是英语学习中一个至关重要的内容,广大初中学生在实际运用时,往往对时态问题倍感棘手,下面我们就归纳复习一下这几种时态。
一、一般现在时
(一)定义
表示经常性或习惯性的动作,或存在的状态,还表示主语具备的性格
和能力及客观真理。
例:I get up at 6:30 in the morning .
She is at home .
(二)构成
主要用动词原形表示,当主语是第三人称单数时,在动词词尾加s/es。
(三)句型
1、肯定句:主语+谓语+其他。
She reads English everyday .
2、否定句:主语+don’t/doesn’t+谓语+其他。
He doesn’t get up at 6:30 in the morning .
3、一般疑问句:Do/Does+主语+V原+其他?
Do you like English ? Yes ,I do ./No, I don’t .
4、特殊疑问句:特殊疑问词+do/does+主语+V原+其他?

(三)用法
1、表示经常性或习惯性的动作,或存在的状态,带与表示频率的时间状语如:often , sometimes , usually,always , everyday year,month...), once/twice a week (month , year , etc.) , seldom ,on sundays等连用。

2、表示客观真理,科学事实、格言警句。

The United States lies by the west coast of the Pacific Ocean. 美国位于太平洋西岸。
3、根据英文语法规定,当主句的谓语动词是一般将来时,那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。
I'll tell him the news when he comes back. 他回来时,我将告诉他这个消息。
If you come this afternoon,we’ll have a meeting .
4、仅为了描述状态、性质、特征、能力等等。这里的目的是为了"描述现阶段的动作或状态",其重点"不是强调动作发生的时间、或进行的状态"。例如:
He can speak five foreign languages .他能说五种外语。
That is a beautiful city .那是座美丽的城市。
Changjiang River is one of the longest rivers in the world. 长江是世界上最长的河流之一。
She majors in music .她主修音乐。

(四)动词第三人称单数形式变化规则

如:help-helps ,clean-cleans ,give-gives等。
2、以s,x,ch,sh或o结尾的动词,在词尾加-es;
如:dress-dresses,fix-fixes,watch-watches,finish-finishes等。
3、以辅音字母加y结尾的动词,把y变为i,再加-es;
如:study--studies,fly-flies,carry--carries等。
4、动词have遇在主语是第三人称单数时,have改为has,
