谓语动词是什么意思（90%的学生都不清楚的英语语法)

很多学生不认识谓语动词，难怪，他们不会造句，因此，不会表达。谓语动词就是∶ 动词原形，动词第三人称单数形式和动词过去式，我们把原形和三单形式归为现在式，那么，谓语动词就是∶ 现在式和过去式两种形式。

一，在句子中认识谓语动词

1. My uncle teaches at a university in Hunan. (teaches是谓语动词)
2. Tom worked at this factory last year. (worked是谓语动词)
3. My aunt has taught in this school for 20 years. (has taught是谓语动词)
4. The train had left when we got to the station.(had left和 got是谓语动词)
5. I will go to the park if it is fine tomorrow.(will go 和 is是谓语动词)
6. I wish I could fly to my hometown.(wish和could fly是谓语动词)

二，句子的各种问句形式和否定形式都是由谓语动词决定的。

1. Does your uncle teach at the university? Yes,he does.
2. Did Tom work at this factory? No, he didn't.
3. Does your sister have to finish her homework tonight? No, she doesn't.(谓语动词have to 是行为动词，当然要用助动词does构成一般疑问句)
4. How long has your aunt taught in this school?(谓语动词has taught是现在完成时态，所以，has 是个助动词，不是行为动词)
5. This book isn't mine.

三，任何句子必须要有谓语动词(除了省略句)，这是学生的致命弱点。

1. I like English very much. 我非常喜欢英语
2. Mary danced like me. 马丽像我那样跳舞。(谓语动词是danced,like 不是动词，是介词，所以，like更本不能做谓语动词。
3. My brother is at home.我弟弟今天在家(当没有行为动词的时候，必须要有一个be动词，不然，句子就没有谓语动词了)
4. My brother watches TV at home.我弟弟经常在家看电视。(谓语动词是watches, 后面的at home 是地点状语)

搞清楚了谓语动词，相信同学们一定会表达了，各个时态也容易理解了。
