half of the class后谓语是单数复数

题目

half of the class后谓语是单数复数

答案

单数 因为half of the class
你要看of后面词的形式 class用单数 谓语就是单数
语法知识就是主谓一致
以下是相关知识
与后接名词或代词保持一致
1） 用half of, part of, most of, a portion of 等词引起主语时,动词通常与of后面的名词,代词保持一致.
Most of his money is spent on books.
Most of the students are taking an active part in sports.
2） 在一些短语,如 many a 或 more than one 所修饰的词作主语时,谓语动词多用单数形式.但由more than… of 作主语时,动词应与其后的名词或代词保持一致.
Many a person has read the novel. 许多人都读过这本书.
More than 60 percent of the students are from the city.百分之六十多的学生都来自这个城市
