Her name is Jane. → Her na me is not / isn’t Jane.

【特别提醒】

I’m …变一般疑问句时,通常为Are you …?

主谓一致法练习

在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚,现归纳总结如下:

一、人称代词he, she, it是第三人称单数。如:

He likes watching TV. 他喜欢看电视。

She has lunch at twelve. 她十二点吃午餐。

It looks like a cat. 它看起来像只猫。

二、单个人名、地名或称呼作主语;是第三人称单数。如:

①Han Mei looks like her mother. 韩梅看起来像她的母亲。

②Beijing is in China. 北京在中国。

③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。

③That car is red. 那辆小汽车是红色的。

④The cat is Lucy's. 这只猫是露茜的。

③This is a pen. 这是一支钢笔。

④That is an eraser. 那是一块橡皮擦。

五、不可数名词作主语时为第三人称单数。如:

②The bread is very small. 那面包很小。

六、当数字或字母作主语时,看作第三人称单数。如:

①"6" is a lucky number. "6"是个吉利数字。
