问题补充：
All the citizens, young and old, walked and sang, beautifully in new clothes of all kinds, the success of their football team.
A. dressing; celebrating
B. wearing; to celebrate
C. dressed; celebrating
D. worn; celebrated
答案：
A. dressing; celebrating
B. wearing; to celebrate
(答案→)C. dressed; celebrating
D. worn; celebrated
解析：句意：所有的公民，老的少的，都穿着漂亮的衣服，走着唱着，庆祝他们的足球队的胜利。dress用作及物动词时,最常用的意思是“给…穿上衣服”。其宾语是反身代词或其他表人的名词,而不是表示衣服的名词。所以这里All the citizens与dress之间是被动关系，应该用dressed ；wear+衣服；All the citizens与celebrate之间是主动关系；用celebrating表示伴随状语。
