A. sold well;are on sale
B. sold out;sell well
C. selling well;sell well
D. for sale;sell well
答案：
A. sold well;are on sale
(答案→)B. sold out;sell well
C. selling well;sell well
D. for sale;sell well
解析：考查易混短语的用法。on sale“出售，廉价出售”， for sale“待售，出售的”， sell well“好卖，畅销”，sold out“卖完”。根据句意可知他的光盘很走俏，已经卖完了，下周再买。第一空用sold out表示自己没有；第二空用sell well说明原因。
