新一輪中考復(fù)習(xí)備考周期正式開始，中考網(wǎng)為各位初三考生整理了中考五大必考學(xué)科的知識點，主要是對初中三年各學(xué)科知識點的梳理和細化，幫助各位考生理清知識脈絡(luò)，熟悉答題思路，希望各位考生可以在考試中取得優(yōu)異成績！下面是《2018初中英語語法之主謂語法一致的原則》，僅供參考！
謂語受主語支配，須和主語在人稱和數(shù)上保持一致，這叫做主謂一致。主謂一致一般遵循三條原則：語法一致原則，意義一致原則和就近一致原則。
1. 語法一致的原則
�。�1）以單數(shù)名詞或代詞，動詞不定式短語作主語時，謂語動詞要用單數(shù);主語為復(fù)數(shù)時，謂語用復(fù)數(shù)，例如：
He goes to school early every morning.
The children are playing outside.
To work hard is necessary for a student.
（2）由and或both……and連接的并列成分作主語時，謂語動詞用復(fù)數(shù)。例如：
Both he and I are right.
Mr Black and Mrs Black have a son called Tom.
但并列主語如果指的是同一人，同一事物或同一概念，謂語動詞用單數(shù)。例如：
His teacher and friend is a beautiful girl.
The poet and writer has come.
�。�3）由and連接的并列單數(shù)主語之前如果分別由each, every修飾時，其謂語動詞要用單數(shù)形式。例如：
In our country every boy and every girl has the right to receive education.
Each man and each woman is asked to help.
�。�4）主語是單數(shù)時，盡管后面跟有 but ,except, besides, with 等介詞短語，謂語動詞仍用單數(shù)。例如：
The teacher with his students is going to visit the museum.
Nobody but two boys was late for class.
Bread and butter is a daily food in the west.
�。�5） 一些只有復(fù)數(shù)形式的名詞，如people, police, cattle, clothes等作主語時，謂語動詞要用復(fù)數(shù)。例如：
A lot of people are dancing outside.
The police are looking for lost boy.
�。�6）由each, some, any, no, every 構(gòu)成的復(fù)合代詞作主語時，謂語動詞都用單數(shù)。例如：
Is everybody ready?
Somebody is using the phone.
�。�7）有兩部分構(gòu)成的物體的名詞，如glasses, shoes, trousers, chopsticks, scissors 等作主語時，謂語動詞用復(fù)數(shù)。例如：
Where are my shoes? I can’t find them.
Your trousers are dirty. You’d better change them.
如果這類名詞前用了a pair of等，則往往用作單數(shù)，謂語動詞的單復(fù)數(shù)形式往往取決于pair的單復(fù)數(shù)形式。例如：
Here are some new pairs of shoes.
My new pair of socks is on the bed.
