　　1) 有些集体名词, 如 police, people, cattle, 等, 形式上是单数, 但谓语动词要用复数。

　　2) 有些形容词加上“the”, 表示一类人, 此时谓语动词要用复数。

　　The old are taken good care of in our country．在我们国家老人需要好好照顾。

　　3．谓语动词的单复数取决于主语的内涵．有些集体名词, 如family, class, group, team 等作主语　时, 若作为一个整体, 谓语用单数, 若强调具体成员时, 谓语动词用复数。

　　My family isnt very large.我的家不太大。

　　2) either和neither作主语, 谓语通常用单数。

　　Has either of them told you about it? 有关此事, 他们中有人告诉过你吗？

　　3) each 以及 any, some, no, every 构成的复合代词作主语, 谓语动词用单数。

　　Is everybody here? 大家都到了吗？

　　Each of us has something to say.我们每个人都有话要说。

　　4) none 作主语, 既可用作单数, 也可用作复数, 但若none代替不可数的东西时, 谓语动词常用单数。

　　None of the telephones is/are work．没有一部电话能打。

　　None of the water is fit to drink.没有一点水可供饮用。

　　5) all 和some 作主语, 应根据其所代表的名词来决定其单复数。

　　All has been explained．全部内容都作了解释。

　　All were very excited．所有的人都非常兴奋。

　　5．在使用并列主语时, 应注意：

　　1) 由“both…and…”连接的主语, 谓语动词用复数。

　　 Both the boy and the girl are good at English．男孩和女孩都擅长英语。

　　2) 由 or, either…or…, neither…nor…, not only…but also…连接的主语, 谓语的单复数与邻近的主语保持一致．

　　 Either you or he is wrong．或者你或者他是错的。

　　6．There be句型中, 谓语的单复数也是要与其邻近的主语保持一致。
