Subject---Verb Agreement主谓一致在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致
寻其规律,大致可归纳为三个原则,即语法一致、逻辑意义一致和就近一致原则
(一)语法一致原则:语法上一致就是谓语动词和主语在单、复数形式上保持一致
1 、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时,谓语动词一般用单数形式;主语为复数时,谓语动词用复数形式
⑴ His father is working on the farm
⑵ To study English well is not easy
⑶ What he said is very important for us all
⑷ The children were in the classroom two hours ago
⑸Reading in the sun is bad for your eyes
注意:由 what 引导的主语从句,后面的谓语动词多数情况用单数形式,但若表语是复数或 what 从句是一个带有复数意义的并列结构时,主句的谓语动词用复数形式
What I bought were three English books
What I say and do is (are) helpful to you
2 、⑴Lucy and Lily are twins
⑵She and I are classmates
⑶The boy and the girl were surprised when they heard the news

注意:① 若 and 所连接的两个词是
