(3)表示客观、普遍真理

eg:

The moon moves round the earth.3. 一般现在时的疑问句一般以在句首加助动词do，does的方式构成。第三人称单数加does，其他加do，这时动词一概用原形;动词be只需与主语位置对调就行了。

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. 一般现在时的否定式是do not(don’t)或does not (doesn’t)+动词原形来构成的，be动词做谓语动词只需在be后加not构成否定。

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.
