语法专项知识清单:主谓一致
主谓一致:句子的谓语动词与主语在人称和数上保持一致。即谓随主变。英语句子中都必须遵循。
主谓一致三个原则:语法一致原则;意义一致原则;就近一致原则
一、语法一致原则:主语和谓语在语法形式上取得一致,即谓语的单复数由主语形式决定。
1. 单个从句、不定式、动名词等作主语时,视为一个整体,谓语动词用单数。
Going swimming on Sunday _____ one of his habits.(be)
To run faster ______(need) more practice.
★注意:what 引导的主语从句,谓语形式由后面表语单复数而定。
eg.What they need ____ time.(be)
What they need ____ books.(be)
2. 当主语是不定代词each,either,neither及no-,any-,some-,every-构成的复合不定代词,谓语动词用单数。
eg.Somebody _____ waiting for you at the gate.(be)
Either of the shirts_____ me very well.(fit)
★注意:none 做主语,表可数名词复数,谓语动词单复数均可
None of the students___________ the answer.没有学生知道答案。
3. many a/an或more than one +名词作主语,谓语动词用单数。
eg. Many a man _____not understand Mike’s idea.(do)
More than one student ______passed the exam.(have)
★注意:more+可数名词复数+than one做主语,谓语动词用复数
More members than one______ against the idea.
VS →More than one member ______ against the idea.(be)
4.由and 或者both...and...连接的并列主语时,谓语动词用复数。
eg.Reading and writing _____very important.(be)
Both his mother and his father_____ gone there.(have)
★注意①:当主语由and连接时,如它表示同一人或物时,谓语用单数。
eg.The singer and dancer is from Hebei. 这位歌手兼舞蹈家来自于河北。(表示同一人或物时,只有一个冠词。)
VS→The singer and the dancer are from Hebei.这位歌手和这位舞蹈家都来自于河北。
The girl and winner (is,are) jumping with joy. 那位获胜的女孩正高兴地跳着。
A math teacher and a Chinese teacher( is,are )in the room.房间里有一位数学老师和语文老师。
★注意②: and 连接两并列主语,若前面有each, every, many a, no 修饰时,谓语动词用单数
eg.Every man and every woman _____(be) busy with working now.每个人都在忙着工作。
Many a boy and many a girl _____(have) seen it.许多男孩和女孩已经看见它了。
5.成双成对出现的复数名词(shoes,glasses,gloves,pants, trousers, scissors等) 作主语时,谓语动词用复数。但如果前面有… pair/pairs of; … suit/suits of 等表示量的词语时,谓语动词单复数取决于量词单复数。
eg.His shoes are under the desk.
The pair of shoes_____under the desk.(be)
Three pairs of shoes_____under the desk.
6.主语后插入了短语时,谓语不受他们干扰, 仍由主语决定。 (with, along with,together with, as well as,like, including,except,besides,no less than,more than,rather than等)
eg. I , along with my sister, ___
