1. 動(dòng)詞變化：一般現(xiàn)在時(shí)主要用動(dòng)詞原形表示，但第三人稱單數(shù)后要加詞尾-s，另外be和have有特殊的人稱形式。

在加詞尾-s時(shí)要注意：

讀音：

2. 一般現(xiàn)在時(shí)主要表示：

(1)經(jīng)常性或習(xí)慣性的動(dòng)作，常與這樣的時(shí)間狀語(yǔ)連用：always, often, usually, sometimes等

eg: We always help each other.

It often snows in winter.

I get up early every morning.

(2)表示主語(yǔ)現(xiàn)在的特征、性格、能力等。

eg: He loves sports.

Jane is an outgoing girl.

Tom and Tim both have medium height.

(3)表示客觀、普遍真理

eg:

Two and four makes six.

Water boils at 100℃

The moon moves round the earth.3. 一般現(xiàn)在時(shí)的疑問(wèn)句一般以在句首加助動(dòng)詞do，does的方式構(gòu)成。第三人稱單數(shù)加does，其他加do，這時(shí)動(dòng)詞一概用原形;動(dòng)詞be只需與主語(yǔ)位置對(duì)調(diào)就行了。

eg: Do you like English?

Do they have story books?

What does she do every evening?

Is she at home?

Are you good at English?

4. 一般現(xiàn)在時(shí)的否定式是do not(don’t)或does not (doesn’t)+動(dòng)詞原形來(lái)構(gòu)成的，be動(dòng)詞做謂語(yǔ)動(dòng)詞只需在be后加not構(gòu)成否定。

eg:

I don’t like oranges at all.

She doesn’t work in the TV station.

They aren’t students.

I’m not busy every weekend.
