（14）如果名词词组中心词是“分数或百分数 + of + 名词”，谓语动词的单、复数形式取决于of后的名词或代词的单、复数形式。例如：

　　1）Over three-quarters of the swampland has been reclaimed.

　　2）Two-thirds of the people present are against the plan.

　　（15）定语从句谓语动词的单复数形式应与先行词一致。例如：

　　1）He is one of the men who were chosen to represent the group.

　　2）“Keep cool” is the first of the rules that are to be remembered in an accident.

　　注：当one之前有the only等限定词修饰时，定语从句的谓语动词用单数形式。例如：

　　He is the only one of those boys who is willing to take on another assignment.

　　2.概念一致（语言内容上一致）

　　（1）有些集合名词如crowd， family， team， orchestra（管弦乐队）， group， government， committee， class， school， union， firm， staff， public等，它们作主语时，谓语动词的数要根据语言内容而定。如果它们作为一个集体单位时，动词用单数形式，如就其中的各个成员来说，则谓语用复数形式。例如：

　　1）His family is going to move.

　　2）His family are very well.

　　3）The public is / are requested not to leave litter in the park.

　　注：如这类词后跟有定语从句时，定语从句的谓语动词也遵循概念一致的原则，强调具体成员时，谓语动词用复数，关系代词用who； 强调整体时，谓语动词用单数，关系代词用which.例如：

　　1）The government who were responsible for this event attempted to find a solution.

　　2）The government which was responsible for this event attempted to find a solution.

　　（2）有些表示总称意义的名词，形式上是单数，而意义上却是复数，谓语动词要用复数形式，如people， police， militia， cattle， poultry（家禽）等。例如：

　　1）Cattle were allowed to graze on the village common.

　　2）The police are searching for a tall dark man with a beard.
