数词小结初一英语词汇复习
9.与数词相关的主谓一致原则
1)当名词词组中心词为表示时间、路程、金钱或重量等复数名词时,往往根据意义一致的`原则,把这些复数名词看做一个整体,谓语采用单数形式。如:
Twenty dollars is not enough.
Two months has passed before we realized.
但是如果数词单用,表示人或物,谓语动词一般用复数。如:
Three were killed and ten were missing in that accident.
2)如果名词词组中心词是分数或百分数+of-词组,谓语动词的单、复数形式取决于of-词组中名词或代词的单、复数形式:如果of-词组中名词或代词是单数或不可数名词,谓语动词用单数形式;如果of-词组中名词或代词是复数,谓语动词也用复数形式。如:
Two thirds of the earth is covered with water.
Two thirds of the people present are against the plan.
3)如果主语是many a,more than one+单数名词构成,尽管从意义上看是复数,但谓语动词仍用单数形式。如:
Many a student in this class has hoped a long break.
4)a+单数名词+or two做主语,谓语动词用单数形式。如one or two+复数名词,谓语动词用复数形式。如:
