同学你好~
复数名词+of+单数名词,谓语一般也是复数。
单数名词+of+复数,有不同的情况。
当one of, a portion of, a series of, a species of, a chain of 等结构作主语时,谓语动词要用单数形式
One of those students has passed the examination. 这些学生只有一个考试及格了。
由one and a half + 复数名词或the majority of + 名词作作主语时,谓语动词视名词的单复数形式而定。
The majority of the damage is easy to repair. 大部分的损坏品都容易修理。
plenty of, half of, a lot of, lots of, heaps of, loads of, scads of等 + 可数与不可数名词作主语时,不可数名词的谓语只用单数,可数名词的谓语应为复数。
There is plenty of water in the pail. 桶里还有好多水。
Are there plenty of fresh fruits and vegetables in your diet? 你的饮食中新鲜果蔬充足吗?
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
Over three-quarters of the land has been reclaimed. 四分之三多的土地已经收回了。
pair of / kind of / type of+名词/代词作主语时,谓语动词形式要与of前名词形式保持一致。例如:
A pair of new shoes was bought for the child yesterday.
祝同学学习进步~
