of the warm water already been used up.
A. Two-third;has
B. Two-third;have
C. Two-thirds;has
D. Two-thirds;have

A. Two-third;hasB. Two-third;have(答案→)C. Two-thirds;hasD. Two-thirds;have解析：英语中一般用基数词表示分数的分子，用序数词表示分数的分母。当分子是一时，分数的分母用单数形式，在表示分数时，当分数的分子大于一时，分数的分母要用复数形式。由分数修饰的主语后面谓语动词的数，和被修饰主语的单复数保持一致。选项AB结构有误，the warm water表示抽象含义，不可数，故谓语动词用单数，选C。
