问题补充：
It was a long time before the cut on my hand completely.
A. healed
B. cured
C. improved
D. recovered
答案：
A. healed
B. cured
C. improved
D. recovered
解析：heal 1) 使痊愈, 治愈：The salve will help to heal the wound. (这种药膏能治愈你的伤。) 2) 痊愈 (多指外伤) ：The cut on my leg has healed. (我腿上的伤口以痊愈。) 可见, 本题是heal的第二种用法。cure治疗, 治好; The drug cured my fever. (这种药使我退烧了。) This medicine should cure you of your cold. (这种药定会治好你的感冒。) recover也可以表示“痊愈”, 意为“恢复正常”。例如：1) I think she will recover. (我认为她会痊愈的。) 2) He almost fell ill, but quickly recovered. (他差点病到, 但很快就痊愈了。) 也可以用recovered做表语表示“痊愈, 恢复正常：Are you completely recovered from your illness? (你的病是不是完全好了？)
[注意] recover vi. 用作“痊愈”时, 句子主语通常是人。Improve 改善, 此词无“治疗”或“痊愈”之意。
本题译文：过了很长时间我手上的伤口才痊愈。
