问题
选择题
_______ the secret of nature, the young scientist has little time for entertainment.
A.Devoted to bring out
B.Devoted himself to bringing out
C.Devoted to bringing out
D.Devoting to bring out
答案
答案:C
题目分析:考查分词做状语和词组:句意:致力于揭示自然的秘密,年轻的科学家没有时间娱乐。“致力于”可以是be devoted to doing,或devote oneself to doing,所以要么用Devoted to bringing out要么用Devoting himself to bringing out,选C。
点评:当分词做状语的时候,如果构成分词的动词与句子的主语构成主动关系,就使用现在分词做状语;当二者构成被动关系,使用过去分词做状语。如果分词的动作发生在谓语动词之前,就使用分词的完成式。
