Question

________ is required that every employee here be able to use a computer and speak good English.

A. Which B. What C. As D. It

 

Answer 1

D

分 析：
考查主语从句。句意：这里的每位员工都被要求能熟练操作电脑，会说流利的英语。Which在名词性从句中作定语，选what的话，主语是What is required，句子缺少谓语；选As的话，句子看作非限制性定语从句，required后应该有逗号，排除A、B、C。本句考查的是主语从句的句型，it是形式主语，真正的主语是后面的that从句，类似的还有：It is/was+形容词(strange/impossible)+that从句；It is/was +名词(a pity)+that从句等，故选D。
