Question

          of the coats           made of cotton. They feel comfortable.

A．Two-thirds; is

B．Two-thirds; are

C．Two-third; is

D．Two –third; are

Answer 1

B

分数表示法为：分子用基数词，分母用序数词，分子大于1, 分母加s，在分子与分母之间可加连字符也可不加连字符，所以2/3表示为two-thirds 或two thirds ；分数在句中作主语时谓语和它修饰或指代的名词保持一致。本题中two-thirds指代coats, 所以谓语用复数形式are。故选B。
