一般现在时的否定形式（negative form）

先来说肯定句：

live 动词，生活，居住

I live here. 我住在这里。

You live here.

He lives here.

She lives here.

It lives here.

We live here.

They live here.

一般现在时的否定形式

用助动词don't，第三人称单数(he, she, it)用doesn't，后面加动词原形。

把上面的句子变成否定句：

I don't live here.

You don't live here.

He doesn't live here.

She doesn't live here.

It doesn't live here.

We don't live here.

They don't live here.

请大家练习：

I live in...（我住在……）后面加上你所在的地方，然后变化各种人称，然后再都变成否定句。注意第三人称单数的变化。

下面是有错误的句子，哪里错了呢？

X ①He live in London. X

X ②He does live in London. X

X ③He don't live here. X

X ④He doesn't lives in London. X

正确句子：

①He lives in London.

②He lives in London.

③He doesn't live here.

④He doesn't live in London.
