y _______ prices of the same goods in two different supermarkets has caused heated debate among citizens.
A．compared
B．comparing
C．compares
D．being compared
答案
答案：B
考查非谓语动词。分析句子结构可知，该句的主语是a survey，谓语动词是has caused，宾语是heated debate。可见，句子结构是完整的，因此我们要选择的只能是非谓语动词形式。survey与compare之间存在主动关系，因此用现在分词短语作后置定语。
