 主谓一致是指：
a. 语法形式上要一致，即单复数形式与谓语要一致。
b. 意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。
c. 就近原则，即谓语动词的单复形式取决于最靠近它的词语，

  一般来说，不可数名词用动词单数，可数名词复数用动词复数。
There is much water in the thermos.
 
   但当不可数名词前有表示数量的复数名词时，谓语动词用复数形式。

1 、并列结构作主语时谓语用复数

The iron and steel industry is very important to our life.

典型例题
The League secretary and monitor ___ asked to make a speech at the meeting.
A. is B. was C. are D. were
答案 B. 注： 先从时态上考虑。这是过去发生的事情应用过去时，先排除 A. ， C. 。本题易误选 D ，因为 The League secretary and monitor 好象是两个人，但仔细辨别， monitor 前没有 the ，在英语中，当一人兼数职时只在第一个职务前加定冠词。后面的职务用 and 相连。这样本题主语为一个人，所以应选 B 。

3 、谓语动词与前面的主语一致

5 、指代意义决定谓语的单复数

All is right. ( 一切顺利。 )
All are present. ( 所有人都到齐了。 )

2 ） 集体名词作主语时，谓语的数要根据主语的意思来决定。如 family, audience, crew, crowd, class, company, committee 等词后用复数形式时，意为这个集体中的各个成员，用单数时表示该个集体。
