Question

【题目】It’s said that ______ of the water around the world ______ polluted.

A. two third; is B. two third; are C. two thirds; is D. two thirds; are

Answer 1

【答案】C

【解析】句意：据说世界上三分之二的水被污染了。two thirds是三分之二，分子用基数词，分母用序数词，分子大于一的时候，分母要加s，因此A和B两个选项分数的构成不对，先排除。这个分数修饰了后面的名词water，是不可数名词，故谓语动词用单数，选C。
