什么才是真正的谓语动词？(英语语法)

摘要：现代英语语法明确规定，任何句子必须要有一个谓语动词，这个谓语动词就是动词原形，过去式和第三人称单数形式。更深一步的理解是，真正的谓语动词是可以随着句中的主语，有时态，人称和数的变化，就是一个单词。而动词不定式，动名词，现在分词和过去分词都不符合这个条件，所以它

现代英语语法明确规定，任何句子必须要有一个谓语动词，这个谓语动词就是动词原形，过去式和第三人称单数形式。更深一步的理解是，真正的谓语动词是可以随着句中的主语，有时态，人称和数的变化，就是一个单词。而动词不定式，动名词，现在分词和过去分词都不符合这个条件，所以它们都不是谓语动词。

一，各种时态中的谓语动词

We have lunch at school every day.（have）They are having a meeting in the room.(are)I am going to be a doctor in the future.(am)Tom has come back from the school.(has)Mary walked to school yesterday.(walked)My mother was making dinner at six yesterday evening.(was)The train had left when we got to the station.(had, got)He said he was arriving here on time.(said, was)

二，情态动词都是谓语动词

含有情态动词的句子，谓语动词只能是情态动词，因为一切问句和否定都是以情态动词展开的，那个动词原形没有任何变化，只是跟在后面，或者不跟。

Mary can speak Japanese. (can)Can Mary speak Japanese? Yes, she can.（回答不跟）Mary can't speak Japanese.We will go swimming tomorrow.(will)I'd like to take part in the activity.(would)We'd better not go there too early.(had)You needn't have driven here.(need)

三，被动语态中各个时态的谓语动词

被动语态中的谓语动词，也是一样有变化的。过去分词只是跟在后面，表示这是被动结构，不是真正的谓语动词。一切否定和问句形式都是以谓语动词展开进行的，与过去分词无关，既变谓语动词即可。

English is spoken in the world.(is)The thief was caught last night.(was)The bridge has been completed.(has)A school will be built in our school.(will)The hospital is being built. (is)The hospital isn't being built. (否定句)Is the hospital being built?(问句)

四，含有非谓语动词的句子

含有非谓语动词的句子，改为问句和否定句的时候，只看谓语动词即可，非谓语动词跟在后面。

We like playing basketball after school.(like是谓语动词)Do you like playing basketball after school?We don't like playing basketball after school.I know the girl dressed in red.(know是谓语动词)Do you know the girl dressed in red?I don't know the girl dressed in red.

五，造句要先保证谓语动词，再考虑非谓语动词

任何一个简单句必须要有一个谓语动词，如果还有其它动词，必须考虑非谓语动词。表示主动用现在分词，表示被动，用过去分词。表示将来目的，用动词不定式。还有一些固定非谓语动词词组，如seem to do, happen to do这些需要大家多记，多用。在写句子的时候，切记，不要把介词或者形容词当动词使用。

我骑车上学。I go to school by bike或者I ride my bike to school.我昨天骑车(上学)的。I was by bike yesterday.骑车使身体健康。Riding bikes makes us healthy.My teacher asked me not to be late.老师叫我不要迟到。

六，思考题

判断这些句子是否正确。为什么？

We need some good helpers like you and him.You are of great beauty dressed in red.The house is built of stones feels comfortable to live in.I can with you go to the party.Don't late for school.
