英语主谓一致的三个原则
主谓一致的三个原则
主谓一致的三个原则在英语中谓语动词在人称和数上必须同主语保持一致。
确定主谓一致要根据以下三个基本原则：一、语法一致原则, 即谓语动词要和它的主语在形式上取得一致，即单数主语用单数动词，复数主语用复数动词。
但要注意以下几种情况：1由and 连接并列主语时，谓语动词常用复数。

如：Each book and each paper was in proper place. 每本书、每张纸都摆放得井井有条。

2. 单个不定式、动词-ing、从句作主语时，谓语动词用单数。

主谓一致的原则
主谓一致的原则主谓一致是英语语法中的基本原则之一，指的是主语和谓语在人称和数上要保持一致。
主谓一致的正确运用能够使句子表达更加准确，符合语言规范。
本文将详细介绍主谓一致的原则，并通过一些例子来加深理解。
一、基本原则在英语句子中，主语和谓语之间必须保持一致，具体包括以下几个方面：1. 人称一致：主语是第一人称（I、we）、第二人称（you）或第三人称（he、she、it、they）时，谓语动词的形式必须与之一致。
例如：- I am a student.（我是一名学生。
）- He sings beautifully.（他唱得很美。
）2. 数一致：主语是单数形式时，谓语动词的形式也要用单数；主语是复数形式时，谓语动词的形式也要用复数。
例如：- The dog barks loudly.（这只狗叫得很大声。
）- The birds are chirping.（鸟儿正在鸣叫。
）3. 特殊情况：有些特殊情况下，主谓一致的原则会有一些变化。
例如：- 不定代词：somebody, anybody, nobody, everybody等当作主语时，谓语动词形式使用第三人称单数形式。
例如：Nobody wants to go with me.（没有人想和我一起去。
）- 连接词：and连接的主语，如果表示同一个人或物时，谓语动词的形式使用第三人称单数形式；如果表示不同的人或物时，谓语动词的形式使用第三人称复数形式。
例如：Tom and Jerry is a famous cartoon.（汤姆和杰瑞是一部著名的卡通片。
）The boys and girls are playing in the park.（男孩和女孩们正在公园里玩耍。
）二、例题分析为了更好地理解主谓一致原则，以下通过一些例题来进行详细分析。
例题1：The team _____ working on the project.（be）在这个例句中，主语是"the team"，是单数形式，因此谓语动词的形式应该使用单数，填入be的单数形式"is"，句子变为："The team is working on the project."例题2：He and his friends _____ going to the concert.（be）在这个例句中，主语是"he and his friends"，表示多个人，因此谓语动词的形式应该使用复数，填入be的复数形式"are"，句子变为："He and his friends are going to the concert."例题3：One of the students _____ the exam.（fail）在这个例句中，主语是"one of the students"，表示多个学生中的一个，因此谓语动词的形式应该使用第三人称单数，填入fail的第三人称单数形式"fails"，句子变为："One of the students fails the exam."三、常见错误在使用主谓一致时，常见的错误包括以下几种：1. 混淆主谓的人称和数：主语与谓语之间的人称和数要保持一致，不可以混淆。

如：About 30 percent of the pupils were absent that day. 那天大约有30%的学生未到。
Three-fourths of the surface of the earth is covered by sea. 地球表面的四分之三是海。
【注意】在现代英语中，有时即使该结构中的名词为复数，其谓语也可用单数(即将其视为整体)：Over sixty per cent of families own [owns] a television. 百分之六十以上的家庭已拥有电视机。
3.“one in [out of]+复数名词”作主语此时谓语动词通常用单数。
如：Only one in ten students has passed the examination. 只有十分之一的学生通过了考试。
One out of twelve bottles was broken. 每12个瓶子中有一个破了。
【注意】在非正式文体中有时也用复数谓语。
如：Nationwide, one in five adults are illiterate. 就全国范围而言，五个成年人中有一个是文盲。
4.“all of (some of, none of, half of, most of, lots of, plenty of)+名词”作主语此时谓语动词的数与其中名词的数保持一致。
如：Most of the people are against the plan. 大多数人反对这个计划。
Most of the Earth’s surface is covered by water. 地球的大部分地区被水覆盖。
Half of the apple is bad. 这个苹果有一半是坏的。
Half of the apples are bad. 这些苹果当中有一半是坏的。
5.“one and a half＋复数名词”与“a＋单数名词＋and a half”作主语此时国内不少书认为，这两个结构作主语，谓语均用单数。
如：One and a half months has passed. / A month and a half has passed. 已经过去了一个半月。
但是，国外一些词书则认为，谓语动词的数取决于这两个结构中名词的数：One and a half months have passed. / A month and a half has passed. 已经过去了一个半月。
