主谓一致
主谓一致是指:
1) 语法形式上要一致,即单复数形式与谓语要一致。
2) 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。
3) 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。
Ten thousand tons of coal were produced last year.
主谓一致中的靠近原则
1)当there be 句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。
There is a pen, a knife and several books on the desk..
There are twenty boy-students and twenty-three girl-students in the class.
2)当either… or… 与neither… nor, 连接两个主语时,谓语动词与最邻近的主语保持一致。 如果句子是由here, there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。
Either you or she is to go.
Here is a pen, a few envelops and some paper for you.
