___of the workers in this factory is about two hundred,____ of them are women workers
A:the number.first third B:the number,one third C:a number.half D:a number,three quarters

Answer 1

B
第一空：主句中的谓语是is,说明主语是单数.故选the number.因为a number of表示“许多”“大量”,它接复数名词,谓语用单数.
第二空：one third三分之一.分数的表示法：分子用基数词,分母用序数词.如果分子大于一,分母要用复数形式.如：two thirds三分之二.
不明白的再问哟,请及时采纳,多谢!
