1. 动词变化：一般现在时主要用动词原形表示，但第三人称单数后要加词尾-s，另外be和have有特殊的人称形式。
在加词尾-s时要注意：

2. 一般现在时主要表示：
(1)经常性或习惯性的动作，常与这样的时间状语连用：always, often, usually, sometimes等
eg: We always help each other.
It often snows in winter.
I get up early every morning.
(2)表示主语现在的特征、性格、能力等。
eg: He loves sports.
Jane is an outgoing girl.
Tom and Tim both have medium height.
(3)表示客观、普遍真理
eg:
Two and four makes six.
Water boils at 100℃
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.
