学文网（The summit of subject-verb agreement）英语中，主谓一致问题是学习中的一个难点和重点，高考也常对此设考题。新教材中多次提到这一语法现象，现结合教材与我多年的教学总结归纳如下，供高中学生参考。
一、语法形式上的主谓一致：
1、and并列两个名词、代词作主语时，谓语动词常用复数形式。
eg: Tom and Jim are good friends. 汤姆和吉姆是好朋友。
He and I are going to attend the meeting tomorrw.我和他将参加明天的会议。
2、当and连接两个并列主语指同一类事物或同一身份的人，且and后的名词前无冠词时，谓语动词用单数。
eg: The worlcer and witer is to attend our party.那个工人作家将出席我们的晚会。
Bread and milk is beautiful food.牛奶面包是有益健康的食物。
3、当两个并列主语被限定词no、every、each、manya修饰时，谓语动词用单数。
eg: No man and no animal is to be found on the moon.月球上尚未发现人类和动物。
Every student and every teacher is to take part in the discussion.每个学生和每个老师都将参加讨论。
Many a doctor and many a nurse is busy with their work.医生和护士都在忙于工作。
4、如并列主语指成双成对的物品时，谓动动词用单数。
eg: A fork and a knife is used instead of chopsticks.刀叉用来代替筷子。
5、就远原则：
当句子的主语后面跟有附加成份together with (和…一起)、with、as well as、besides、but、except、like、no less…than (和…一样)、including、as much as (和…一样)、rather than (而不是)，谓语动词的数不受这些附加成份的影响，而是与主语保持一致。
eg: Mr Smith together with his wife and children has gone to America.史密斯先生带着老婆孩子去了美国。
No one but Tom and Jack was invited to the party.除了汤姆和杰克没有人被邀请参加晚会。
The teacher as much as the parents is to blame.教师和家长一样应受责备。
Eight people including 3 children were injured in the car accident.在这场车祸中有8人受伤，包括3个孩子。
6、就近原则：
①由并列连词or、either…or、nor、neither…nor、not only…but also…等连接两个并列主语时，谓语动词的数应与最近的主语保持一致。
eg: He or you are to blame.你或他都应受责备。
Not only the earth but also the planets move around the sun.不仅地球而且其它行星也围着太阳运转。
Neither the nor you are right.他不对，你也不对。
②在句型There be…、Here be…中，谓语动词的数通常与be动语仅换的主语保持一致。
eg: There is a book, some pens and a box of chalk on the desk.课桌上有一本书，几支笔还有一盒粉笔。
Tom, Here is a letter for you.汤姆，这儿有你的一封信。
二、意义上的主谓一致：
1、表示时间、价格、距离、长度、重量等复数名词作主语时，被视为一个整体，谓语动词用单数。
eg: Five years is needecl to realize the plan.实现这个计划需要五年的时间。
A million pounds is a large sum of noney.一百万英磅是一大笔钱。
Ten minutes is enongh to finish the work.完成这项十分钟就够了。
2、集体名语family、class、group、team、crew、committee、company、crowd等作主语时，若看作一个整体时，谓语动词用单数；若看作若干个个体，谓语动词用复数。
eg: My family is a happy one.我的家庭是一个幸福的家庭。
When I got home last night, my family were watching TV.昨晚我到家时，我的家人在看电视。
The class are listening to their teacher attentively.学生们正在专心地听老师讲课。

3、一些形式上是复数，意义是单数的名词。如：politics、physics、news、means、mathematics等作主语时，谓语动词用单数。
eg: Mathematics is a science.数学是一门科学。
The United Nations was founded in1945.联合国成立于1945年。
Every means has been tried.每种方法都尝试过了。
而trousers、clothes、shoes、glasses、scissors等复数名词作主语时，谓语动词用复数。但如这些名词前有限定词a pair of、a suit of修饰时，谓语动词则用单数。
eg: This kind of glasses is made of glass.这种眼镜是玻璃制成的。

4、一些形式上是单数，意义是复数的名词。如people cattle、police、public、mititia等作主语时，谓语动词用复数。
eg: Traffic police are always busy.交警总是很忙。
The public were invited to express their opinions.公众被邀请去发表看法。
但people作"民族"、police作"警方"解释，作主语，谓语动词用单数。

The police is offering a reward to anyone who can give information about the lost cheild.警方给提供有关那个失踪男孩信息的人提供悬尝。
三、其他情况的主谓一致：

What the srudents need are books.学生们需要的是书。
3、all、some、most、heaf、more、part、the rest none等名词、代词作主语时，谓语动词的数要根据它们所修饰的名词或所指代的名词的数来决定。
