　　 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 .
