three quarter of a book为什么quarter没用复数
three quarter of a book为什么quarter没用复数
这个结构错了吧?从什么地方来的?
one quarter=one fourth
two quarters=two fourths
three quarters=three fourths
应该加s的.
再问: 请问后面的谓语用单数还是复数?谢谢
再答: 分数词当主语,由它后面的名词的数决定: 如: Three quarters of the book is still not finished. Three quarters of the students are boys.
