十三 主谓一致
主谓一致:谓语动词的形式要和主语保持一致。当主语是第三人称单数、可数名词单数或者不可数名词、一句话或者一件事时谓语动词用单数。
1 当两个名词或者代词由and连接时,谓语动词一般用复数形式。
Eg My brother and I have seen the film.
当and不表示并列含义时,连接的两个名词在意义上表示同一个人、物或者概念时,谓语动词用单数。
Eg The singer and dancer is performing on the stage.
2 两个并列名词由each every many a no修饰时,谓语动词用单数。
Eg Many a student was late for school.
3 集合名词 group class family army enemy 做主语时,如果强调整体谓语动词用单数,如果强调个体成员,动词用复数形式。(the加上名词化的形容词表示一类人,谓语动词用复数)
My family is full of love and warmth.
My family are having supper.
4不定代词 no one each the other 以及复合不定代词someone somebody something anyone anybody anything everyone everybody everything nobody nothing 做主语,谓语动词用单数。
5 none 和neither既可以用单数也可以用复数,但是当它们指代不可数名词时,谓语动词只能用单数。Neither做形容词时+可数名词单数,谓语动词用单数形式。
6 就近原则:谓语动词的形式与离动词近的主语保持一致。or either…or… neither…nor… not only…but also…,there和here引导的句子。
7 就远原则 with, along with, together with, as well as, like, rather than, but, except, besides, including, in addition to。
but except besides的区别 besides 除…之外还有,是一种累加关系,but和except表示除…之外,在整体中除去,是一种排除关系。But 通常与不定代词连用。
8 表示时间 距离 金钱 重量的复数名词表示一个整体量用作主语,谓语动词用单数,如果强调数目或数量,谓语动词用复数。
