英语中分数词,分子是基数词,分母是序数词,分子是一,分母用单数形式,分子超过 一,分母用复数形式。
所以 三分之二: two thirds 或two-thirds 都正确,但two third 或two-third是错误的。
至于 two thirds 和 two-thirds 的区别,我只能说two-thirds更常用,其他就不知了。
How many students are there in your class?
--D-----the students is fifty-one. -----of them are girls.
A.a number of;Two-third B.a number of;Tow-thirds
C.The number of; D.The number of;Two-thirds
要啊!那是固定用法!与比如说“a two-day holiday”不同!
For example:one-third two-thirds.
Are you clear?
