Question

【题目】Most of her spare time ______ , she still kept on her research in the library．

A. occupied B. to be occupied

C. was occupied D. had been occupied

Answer 1

【答案】A

【解析】独立主格或独立结构：由名词/代词 + 非谓语动词/介词短语等构成，,在句中作状语，相当于一个状语从句或并列句。这里的spare time与occupy之间为被动关系，故用过去分词。句意：大多数空余时间都被占据了，她仍然在实验室继续她的研究。故A正确。
