主谓一致
含义:主谓一致指的是句子的谓语动词与其主语在数上必须保持一致,句子的主语是第三人称单数,其谓语动词须用第三人称单数,主语是复数,则谓语动词用复数形式。
原则:英语中的主谓一致主要遵循三个原则:
意义一致原则
语法一致原则
邻近原则
语法一致原则
主语和谓语通常是从语法形式上取得一致,即主语是单数形式,谓语动词也采取第三人称单数形式;主语是复数形式,谓语动词也采取复数形式。
e.g.Mr. Black is a well-known scientist on AIDS.
布莱克先生是著名艾滋科学家。
These books are intended for children under nine years old.
这些书是专门为九岁以下的儿童设计的。
● 意义一致原则
所谓意义一致原则是指谓语动词的变化是以主语所表达的单、复数概念而定。
e.g.Three months has passed since you left.
你已离开三个月了。(three months表示单数概念。)
The professor and writer is invited to many universities to deliver lectures.
这位教授兼作家被邀请到很多大学作报告。(教授与作家是同一个人,是单数。)
The old are very well taken care of in our city.
老年人在我们城市被照顾得很好。(the old指所有的老年人,为复数概念。)
● 邻近一致原则(就近原则)
邻近一致原则是指谓语动词的变化以靠近谓语动词的主语部分而定。
e.g.Neither his parents nor he himself is a bank clerk.
他父母和他本人都不是银行职员。(根据靠近谓语的主语he而定。)
Not Jack but his parents are to blame for the home accident.
不是杰克而是他父母应为这个家庭事故受到责备。
