中单选题Over the past 30 years, her writings have influenced debates concern animal rights, the environment and evolutionary theory.
A.have influenced debates concerning
B.have influenced debates concerned
C.influence debates concerning
D.influence debates have concerned
参考答案：A
答案解析：这句话的意思是：在过去30年里，她的著作影响着有关动物权利、生态环境和进化论的讨论。这句话的主语是her writings,谓语部分为have influenced debates，后面的concerning为介词，表示“有关、关于”，因此A为正确答案。B项中concerned错误，concerned如果作debates的后置定语的话，后面的animal rights，the environment and evolutionary theory则多余。C项时态错误，over the past 30 years这一时间状语通常时态为完成时。D项结构错误，her writings influence debates作主语，语意不通。答案为A。
