英语中主谓一致是指句中的谓语动词和主语在人称和数上保持一致。在做涉及主谓一致的练习时,同学们有时会觉得顾此失彼。究其原因,往往是没有把握住主语的真正内涵,考虑不周全。今天小编为大家整理了三大原则之一的语法一致原则的相关知识点,快来看一下吧。

动词不定式、动名词或名词性从句作主语时,谓语动词用单数形式。如:

To be an honest person is not easy.

Smoking does harm to health.

What he believes is not true.

由and或both.„and连接的名词作主语时,谓语动词用复数形式。如:

The red coat and the white coat are very beautiful.

主语后面有as well as, together with, along with, but, like, except, including等非并列连接性短语时,谓语动词要和主语在人称和数上保持一致。

He as well as me is responsible for this thing.

I, together with my sister, pan to have a picnic.

No one except him agrees with this plan.

在倒装句中, 谓语动词的数应与其后的主语保持一致。如:

On the desk is a red pen.

Such are the facts.

语法一致原则在主谓一致中占有很大的比重,当三种原则发生冲突时,也应以语法一致原则为主。总之,在语言实践中,我们不仅要记住一般的语法规则,更要把握好有些名词的内在涵义,才能做好有关主谓一致的题目。
