主谓一致的三大原则之语法一致原则

主谓一致的三大原则之语法一致原则
在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致。寻其规律,大致可归纳为三个原则,即语法一致、逻辑一致和就近一致原则。高考中的单项填空题与短文改错题经常对主谓一致问题进行考查。 
1. 语法一致:就是谓语动词和主语在单、复数形式上保持一致。
(1) many a +名词,作主语时,从意义上看是复数,但谓语动词常用单数。
例:很多学生被派去植树。
Many a student has been sent to plant trees. 
(2)more than a (an)/one +名词,作主语时,谓语动词常用单数。
例:不止一个教师得到了花。
More than one teacher gets the flowers.  
(3)动词不定式、动词-ing形式短语,作主语时,谓语动词常用单数。
例:晚饭后出去散步是一个好习惯。

Going out for a walk after supper is a good habit.

(4)and连接的两个单数名词前若用each, every, no修饰,该名词短语作主语时,谓语动词用单数形式。
例:Every student and more than one teacher was in the classroom.
每一名学生和不止一位教师都在教室。
(5)the following作主语时,谓语动词的数与后面名词的数保持一致.
例:The following information was correct at time of going to press.
