— What does the fresh juice contain?

— ________of the juice ________ orange. It's very pure.

A. Four-fifths; are            B. Four-fifth; is          C. Four fifths; is

 

【答案】

C

【解析】

试题分析: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。句意:鲜橘子汁含有什么?——果汁的五分之四是橘子。非常纯。由分数修饰的名词后面的谓语动词,与被修饰的分数保持一致,orange本句中是物质名词,不可数,故谓语动词用单数,选C。

考点:分数表达及主谓一致

点评:英语分数的表达规则比较固定,学习中应牢记这些基本规则。需注意的是,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。
