______ his body and soul to bringing up-to-date technology and International attention to China's Aids problem, Dr David Ho, born in Taiwan, spent little time with his family．

A．DevotedB．To devoteC．Being devotedD．Devoting

D

解析試題分析：考查分詞做狀語，當動詞和邏輯主語是主謂關(guān)系關(guān)系時，用現(xiàn)在分詞；當動詞和邏輯主語是動賓關(guān)系時，用過去分詞形式，動詞devote和邏輯主語Dr David Ho是主謂關(guān)系，句子意思“他花費很長的時間全心全意的專心于帶來最新技術(shù)和中國的艾滋病問題”，所以選D
考點：考查分詞做狀語
點評：固定詞組devote to意思“專心于”，to是介詞后跟名詞或動名詞，spend money/time (in) doing sth意思“花費時間或金錢做某事”，up-to-date technology意思“最新技術(shù)”， China's Aids problem意思“中國的艾滋病問題”，固定詞組要靠平時多記多積累。
