幾個容易弄錯的主謂一致問題

1.“many a +名詞”和“more than one +名詞”作主語

謂語動詞的數通常用單數(即遵循語法一致的原則)：

Many a child was playing there. 很多小孩在那兒玩。

More than one student has failed the exam. 不止一個學生考試未及格。

2. each 用于復數名詞后作同位語

此時謂語動詞用復數：

They each have an English-Chinese dictionary. 他們每人都有一本英漢詞典。

The young people each carry a big bag. 這些年輕人個個背著一個大袋子。

3. 主語后接in addition to, with, along with, together with, except, but等介詞

其后的動詞形式取決介詞前主語：

Nothing but trees was to be seen. 除了樹木之外什么也看不見。

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

Jim, together with his classmates, has seen the film. 吉姆和他的同學都看過這部電影。

4. means作主語

名詞means(方法)單數與復數同形，用作主語時，其謂語的單復數要視具體含義而定(尤其注意其前的修飾語)：

These means are very good. 這些方法很好。

Such a means is really unpleasant. 這樣的方法確實是令人不愉快。

若沒有特定的修飾語或語境，則用單數或復數謂語均可：

There is [are] no good means. 沒有好的方法。

Are [Is] there any other means of doing it? 做這事還有其他的什么辦法嗎?
