Question

【题目】 About _______ of the workers in the factory were born in ______.

A. two thirds; the 1970S B. two thirds; 1970s

C. two third; 1970 D. two third; 1970s

Answer 1

【答案】A

【解析】

试题分析：句意：工厂里大约三分之二的工人生于二十世纪七十年代。分数的分子用基数词，分母用序数词，当分子是一时，分母用单数，分子大于一时，分母用复数，因此三分之二表示为two thirds；某世纪某年代，用整十的复数形式，所以选A。
