1.概念:一般现在时表示经常的、习惯性的动作或存在的状态

2.构成:一般现在时的构成主要有两种形式,一般现在时用行为动词的原形,但第三人称单数作主语时,动词的词尾要加-S。: 21世纪教育网版权所有

(1)be型:句子的谓语动词只有be(am,is或are)

a.肯定句中,只出现be,如

I am a student.我是一名学生。

b.否定句中,要在be后面加not,如

She isn't a teacher.她不是教师。

c.一般疑问句,要将be放在句子开头(注意句首字母大写),句尾用问号,答语用Yes,主语+be.或No,主语+be+not.如: 21cnjy.com

—Are you ready?—你准备好了吗?

—Yes,I am.—是的,我准备好了。

(—No,I'm not.—不,我没准备好。)

(2)实义动词型:句中的谓语动词为实义动词(也叫行为动词)

a.肯定句中,只出现实义动词,如

I get up in the morning.我早晨起床。

b.否定句中,要在实义动词前面加do(does)+not,do(does)作助动词,本身无意义,常与not缩写成don't(doesn't),如: 21教育网

I don't like vegetables.我不喜欢蔬菜。

c.一般疑问句,要在句子开头加助动词Do(does),句尾用问号,简略答语用Yes,主语+do(does).或No,主语+do(does)+not.如

—Do you like oranges?—你喜欢桔子吗?

—Yes,I do.—是的,我喜欢。

(—No,I don't.—不,我不喜欢。)

3. 一般现在时的用法

时间状语: every…, sometimes, at…, on Sunday

现在一般时动词变化的规则是

1.如果主语是名词复数和第一人称I、 we ,谓语动词不用做任何变化,即仍然用动词原型表示:We usually go to school at 7:30. 我们通常7:30上学去。[go]

My parents give ten yuan to my sister every week.我父母每星期给我妹妹十元钱。[give]

2.主语是任何一个单数名词或者是第三人称单数,谓语动词要进行必要的变化。特别提一点:不可数名词也算作单数处理。

3.谓语动词的变化规律是

(1) 在动词后加-s,-es read - reads,write - writes,say - says

(2) 以s,x,ch,sh 结尾的词加-es teach - teaches,wash - washes,guess - guesses

(3) 以辅音字母+y结尾的词变y为i再加-es try - tries,carry - carries

(4) 特殊变化的词

be (是) - am, is, are

I am ;she/he/it,名词单数都用 is ; we, you, they, 名词复数都用are

have (有) - have, has

I, we, you, they, 名词复数都用have ;she/he/it is, 名词单数都用 has

(5) 助动词,不论单复数、不论什么人称都没有变化,都用 can, may, must, need, ought to 等。而且,句子中有了助动词,谓语动词就不需要有任何变化了,即用动词原形表示。
