主谓一致易错的语法点

1、“many a +名词”和“more than one +名词”作主语

谓语动词的数通常用单数(即遵循语法一致的原则)：

Many a child was playing there. 很多小孩在那儿玩。

More than one student has failed the exam. 不止一个学生考试未及格。

2、each 用于复数名词后作同位语

此时谓语动词用复数：

They each have an English-Chinese dictionary. 他们每人都有一本英汉词典。

The young people each carry a big bag. 这些年轻人个个背着一个大袋子。

3、主语后接in addition to, with, along with, together with, except, but等介词

其后的动词形式取决介词前主语：

Nothing but trees was to be seen. 除了树木之外什么也看不见。

No one except my parents knows anything about this. 除我父母外没人知道此事。

Jim, together with his classmates, has seen the film. 吉姆和他的同学都看过这部电影。

4、means作主语

名词means(方法)单数与复数同形，用作主语时，其谓语的单复数要视具体含义而定(尤其注意其前的修饰语)：

These means are very good. 这些方法很好。

Such a means is really unpleasant. 这样的方法确实是令人不愉快。

若没有特定的修饰语或语境，则用单数或复数谓语均可：

There is [are] no good means. 没有好的方法。

Are [Is] there any other means of doing it? 做这事还有其他的什么办法吗？
