2018年PETS一级考试口试语法知识：主谓一致

(一)、主谓一致三原则

主谓一致是指谓语动词与主语在人称和数上保持一致，主谓一致必须遵循三原则：语法一致原则，意义一致原则，就近一致原则。

1. 语法一致原则：指主语是单数形式，谓语动词用单数形式，主语是复数形式，谓语也用复数形式。

Tom ________(is / are)a good student. 汤姆是个好学生。

They often ________(plays / play)football on the playground. 他们经常在操场上踢足球。

2. 意义一致原则：指主语形式上为单数，但意义为复数，因此谓语动词用复数形式;或主语形式上为复数,但表示单数意义，这是谓语动词用单数形式。

My family ______(is / are)having lunch now. 我们一家人现在正吃午饭。

Twenty dollars ___(is / are)too expensive for the book. 这本书20美元太贵了。

3. 就近一致原则：指谓语动词用单数形式还是用复数形式，取决于最靠近它的主语。例如：

Not only the teacher but also his students _____(like / likes)playing football.

不仅老师喜欢踢足球，而且他的学生也喜欢踢足球。

There ________(is / are)a pen and some books on the desk. 课桌上有一支钢笔和一些书。
