Question

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

Answer 1

D　从语境的搭配看，这里用contribute to表示“导致，促成，造成”。其他动词短语的主要含义：submit to屈服，听从；admit to承认(做错了事，犯了罪)；而C项动词devote是及物动词，要用devote oneself to或be devoted to表示“将时间、精力等投入到、致力于某事”。
