主谓一致
【要点点拨】
英语句子中谓语动词的数必须与主语的人称和数取得一致，这就叫做主谓一致。解决主谓一致主要遵循三个原则：语法一致原则、意义一致原则和就近一致原则。
1：either , neither , each , one , the other , another , anybody , anyone , anything , somebody , someone , something , everything ,everybody , everyone ,no one , nothing ,nobody 做主语时，谓语一般用单数。
Neither of the two sentences is correct .
Everything around us is matter .
(注意：none , neither, all ,any作主语时，谓语可用单数，也可用复数，具体取决于说话人的意思。)
None of them owns/own a car .
Neither of the boys are / is interested in geography.
All are here. And all that can be done has been done.
2 ：表示“时间、距离、金额、重量、面积、体积、容积”等度量的名词做主语时，谓语用单数。
Five minutes is enough .
Four hundred francs is a lot of money .
3：each …and each …，every …and every ;no …and no ;many a …and many a …等结构由于强调个体行为，因此谓语动词使用单数。
Each boy and each girl has got a new English-Chinese dictionary .
No sound and no voice is heard for a long time .
4：从句、不定式、动名词或短语作主语时谓语动词使用单数形式。
To say something is one thing , to do it is another .（to say something , to do 是不定式）
“How do you do?” is not a question but a greeting .（How do you do ?是句子，作主语）
(注意：what 引导主语从句时应注意其所指的具体内容来确定谓语的单复数。)
What we need is more time ,while what they need are more doctors and medicines .
5：one and a half 后面带名词的复数，谓语动词常用单数。
One and half bananas is left on the table .
6：用and 连接的两个名词表示单一概念时谓语动词使用单数。
The headmaster and Party secretary is going abroad next month .
Bread and butter is my usual breakfast .
7 ：有些名词呈复数形式，但并不表示复数概念。
The news is disappointing that a chemical works is to be built in the west of the city .
8：名词由and 或both …and 连接主语时，谓语动词使用复数形式。
Both coffee and beer are on sale in the shop .
