题目内容
After his operation, the old man was back ______ and he began to take exercise as usual.
A. at his feet B. to his feet
C. in his feet D. on his feet
【答案】
D
【解析】
试题分析:考查固定短语。根据句中After his operation和take exercise as usual.可以判断应该是病后恢复,短语on his feet可以指“病后复原”,所以D选项正确。句意:手术后,这个老人又重新恢复了健康并且开始像往常一样锻炼身体了。
考点:考查固定短语。
