（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：�

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。�
