英语主谓一致注意点
主谓一致是中学英语的一项重要语法内容,也是高考必考的语法点之一.虽然主谓一致涉及的语法规则有多条,但面临高考的同学应特别关注以下几点:
一、动词不定式短语、-ing形式短语或名词性从句作主语时,谓语动词一般用单数形式.但what引导从句作主语时,在下列情况下,主句谓语动词多用复数形式:①表语为复数名词时;②what引导的从句是一个具有复数意义的并列结构时.如:
Learning new words and useful expressions is very important for me.
What he’d like is a digital watch.
What we have to learn are the pieces of language that produce inversion.
What I say and think are no business of yours.
二、在定语从句中,关系代词作主语时,谓语动词的数常与其先行词保持一致.但在“one of +复数名词+定语从句”的结构中,从句的谓语常用复数形式;而在“the (only) one of +复数名词+定语从句” 的结构中,从句的谓语常用单数形式.试比较:
I was one of the persons in my office who were invited.
I was the(only) one of the persons in my office who was invited.
三、“分数/百分数+ of + 名词”作主语时,谓语动词的数要与of后面的名词保持一致.如:
Two-fifths of the land in that district is covered with trees and grass.
More than ten percent of the workers are from Paris.
四、由or,either...or...,neither...nor...,not only...but also...,not...but...等连接并列主语时,谓语动词的数通常遵循“就近一致”的原则,即谓语动词的单、复数形式依最接近它的主语而定.特别要注意疑问句中谓语动词的形式.如:
Either her father or her mother calls for her every afternoon.
－ Are either you or he to go there
－ Neither is.
Neither the president of the company nor the sales manager is a college graduate.
五、and / both...and...连接两个并列主语时,谓语动词一般用复数形式.若and连接的两部分指同一人、同一物、同一事或同一概念时,谓语动词则常用单数形式.如:
His lawyer and parents were with him on his trip to Europe.
Both rice and wheat are grown in our country.
Whisky and Soda is always my favorite drink.
(Whisky and Soda意为“威士忌汽水酒”,指同一物)
Your colleague and former college friend is coming to our home tomorrow.
(主语部分意为“你的同事,就是你那位大学时的朋友”,指同一人)
六、在each...and each...,every...and every...,no ...and no...,many a.../more than a(an,one)...等结构之后,谓语动词常用单数形式.如:
Every man and (every) woman is to take part in the election.
Many a child likes it.(=Many children like it.)
七、一些以-ics结尾的学科名词,如mathematics /politics / physics以及news/works(工厂)/means等在形式上似乎是名词的复数形式,但多用作单数名词,此类名词作主语时,谓语动词一般使用单数形式.如:
The paper works was built in 1990.
Every possible means has been used to prevent the air pollution,but the sky is still not clear.
八、一些“成双成套”的名词,如
trousers /pants /glasses /clothes /shoes /scissors/compasses(圆规)等用作主语时,谓语动词常用复数;若此类名词前有a (the/this) pair of /a suit of等量词修饰时,谓语动词则常用单数形式.如:
My glasses are broken.I have to buy a new pair.
The pair of shoes under the bed belongs to Tom.
九、若主语是由“a kind of/a series of等+名词”构成时,谓语动词通常用单数形式;但在“these/those kind/type of+复数名词”之后,谓语动词则常用复数形式.如:
This kind of men is dangerous.
These kind of tests are good.
