Question

(09湖南卷)21. 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

C

解析:

考查省略句式。在if引導(dǎo)的條件狀語(yǔ)從句中，從句中還原應(yīng)為if am not tired from work，根據(jù)省略的原則，所以答案選C。
