Recently a survey _______ prices of the same goods in two different supermarkets has caused heated debate among citizens. (   )A. comparedB. comparingC. comparesD. being compared

步骤 1：分析句子结构
句子的主语是 "a survey"，谓语是 "has caused"，宾语是 "heated debate"。"prices of the same goods in two different supermarkets" 是 "survey" 的宾语，而空格处需要一个非谓语动词来修饰 "survey"。

步骤 2：确定非谓语动词的形式
"compare" 与 "survey" 之间是主动关系，因此应该使用现在分词 "comparing"。现在分词短语 "comparing prices of the same goods in two different supermarkets" 作为定语修饰 "survey"。

步骤 3：验证选项
选项 A "compared" 是过去分词，表示被动关系，不符合句子结构；选项 C "compares" 是谓语动词形式，不符合句子结构；选项 D "being compared" 是现在分词的被动形式，也不符合句子结构。因此，选项 B "comparing" 是正确的。
