When I was the school football team because I was unfit, I knew it was time to quit .

A. taken off, smoking

B. taken up, having smoked

C. taken down, to smoke

D. taken apart, smoking

答案：

(答案→)A. taken off, smoking

B. taken up, having smoked

C. taken down, to smoke

D. taken apart, smoking

解析：考查短语辨析。Take off起飞，脱掉，成功；离开；take up占据，从事于，开始做；take apart分解，拆卸；take down写下，记下；quit doing sth放弃做某事；句意：因为我的身体不好，当我从校球队离开的时候，我就知道是戒烟的时候了。根据句意说明A正确。
