问题补充：

Every evening after dinner, if not from work, I’ll spend some time walking my dog.

A. being tired

B. tiring

C. tired

D. to be tired

答案：

A. being tired

B. tiring

(答案→)C. tired

D. to be tired

解析：本题考查省略句式。如果主句的主语和从句的主语一致，从句的主语连同be 可一起省略，在if引导的条件状语从句中从句还原应为if I am not tired from work根据省略的原则句意：每天晚上吃完晚饭，如果工作不累，我会花时间遛狗。所以答案选C。
