(单选题)

— What’s the matter with you?
— _____ the window, my finger was cut unexpectedly.

A.While cleaning

B.While I was cleaning

C.Cleaning

D.To clean

参考答案：B

参考解析：

本题考查时间状语从句。分析句子成分，主句的主语为 “my finger”，从句的主语为 “I”，主从句主语不一致，不符合时间状语从句省略的条件，故排除A项；又 my finger 不是 clean 这一动作的逻辑主语，排除C、D项。本题为 while 引导的时间状语从句，表示某段时间内的动作，故本题选B。

知识点：

— What’s the matter with you?— _____ the window, my finger was cut unexpectedly.

— What’s the matter with you?
