I think of the materials I listened to at the beginning of the exam easy.
A. three fourths; is
B. third four; are
C. three fourths; are
D. three fourth; are

A. three fourths; isB. third four; are(答案→)C. three fourths; areD. three fourth; are解析：此题考查分数的表示方法。分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子，序数词表示分母。分子超过1，分母要加s.分数修饰名词时，若该名词是不可数名词只能用单数；若是可数名词，用单数或复数均可。但是，若它们在句子中作主语，则谓语动词是用单数还是复数取决于名词，即与分数所修饰的名词保持一致。根据语境可知此句的含义是考试一开始我听到的3/4的材料都非常容易，因materials是可数名词的复数故谓语动词要用复数。故选C。
