【题目】Many Chinese brands, __________their reputations over centuries,are facing new challenges from the modern market.
A.having developed
B.being developed
C.developed
D.developing

【答案】A
【解析】句意：声誉经过几个世纪形成的许多中国品牌正面临着现代市场的新的挑战。brands是逻辑主语，和develop是主谓关系，所以用现在分词，表示伴随状况；再根据“over centuries”可知，应该使用现在分词的完成式，故选A。
