Question

【题目】Secretaries whose jobs mainly involve writing, ________ phone calls and receiving visitors usually work in offices.

A. answeringB. answer

C. having answeredD. to answer

Answer 1

【答案】A

【解析】

考查非谓语动词。句意：秘书的工作主要包括写作、接电话和接待客人，通常在办公室工作。分析句子结构可知，空处和writing, receiving的动作是并列关系，而having answering的动作发生在谓语动词work之前，与题意不符，故选A。
