【C8】
选项 A、attributing
B、devoting
C、contributing
D、directing
答案C
解析 动词辨析题。句意同上。四个动词都能跟to搭配，所以从语义层面进行辨析。attribute to表示“把……归因于”，例如：She attributes her great age to carefully planned diet．(她认为她的高寿是精心安排饮食的结果。)devote to表示“致力于”；contribute to表示“有助于”；direct to表示“把……贯注在”。根据上下文可以推断出空格处表示的含义应为“有助于”，所以[C]contributing为答案。
