Zhao Benshan, whose overwork ____ his health failure last year, is reported to have performed less successfully in the 2010 Spring Festival Gala on CCTV． A. submitted to B. admitted to C. devoted to D. contributed to

正确答案是 D. contributed to。

句子分析：
“赵本山去年因过度劳累 ____ 健康问题，据报道在2010年央视春晚上表现不如以往成功。”
空格处需要表示“导致”“促成”他的健康问题。

选项辨析：

A. submitted to
意思是“屈服于，顺从”，如 submit to pressure（屈服于压力），不符合“导致健康问题”的逻辑。

B. admitted to
可表示“承认”或“允许进入（场所、学校等）”，如 admitted to hospital（被送进医院），虽然可以说“admitted to hospital”，但主语一般是人，且是被动式，这里主语是 overwork，不合适。

C. devoted to
意思是“致力于，献身于”，如 devote time to work，主语通常是人，且不表示因果关系。

D. contributed to
意思是“促成，导致，是……的原因之一”，主语可以是物或事，如 Overwork contributed to his illness.
这完全符合句意：过度劳累导致了他去年的健康问题。

正确句子：
Zhao Benshan, whose overwork contributed to his health failure last year, is reported to have performed less successfully in the 2010 Spring Festival Gala on CCTV.

所以选 D。
