Question

【题目】Every evening after dinner, if not ________ from work, I will spend some time walking my dog.

A. being tired B. tiring

C. tired D. to be tired

Answer 1

【答案】C

【解析】

试题分析：if not tired from work是if I'm not tired from work的省略形式。在条件、时间等状语从句中，如果从句的主语与主句的主语相同且含有系动词be，可把从句中的主语和系动词be省略。故选C。
