two hundreds of students还是two hundred of students

问题描述:

two hundreds of students还是two hundred of students

答案:two hundred students
解析:当hundred,thousand,million,billion等词前面有具体的数词修饰时,不变成复数,还用单数,而且没有of,当前面没有具体的数词修饰时,表示泛指数目时,这些词前面加s
如:five hundred students
hundreds of students
two thousand people
thousands of people
