问题描述:

We have already finshied ( ) of the work .We will finish the rest inthis week.
A two third B second thirds
C two thirds D second third

Two-third
这是分数的表达方式
就是三分之二的意思.
比如two thirds 基数词表分子,序数词表分母,当分子大于一时,分母要用复数.
在使用连字符(-)时,就是形容词了,比如
two-third是复合形容词,形容词没有复数形式 .
所以正确的表达是two thirds或者two-third,选项里面只有C可以.
