Question

I think _________ of the materials I listened to at the beginning of the exam __________ easy.

A．two thirds; is

B．second three; are

C．two thirds; are

D．two third; are

Answer 1

C

试题分析：句意：我认为这个学期初我听过的三分之二的材料是简单的。two thirds三分之二，表示分数时分子用基数词，分母用序数词，分子超过1时，分母的序数词要加s；material是可数名词，所以谓语动词要用复数，故选C。
