All her time

All her time________ research, the scientist has no time for films.

devoted to do

is devoted to doing

devoting to doing

devoted to doing

答案及解析：本题考查独立主格结构D选项，句意为“那位科学家把所有时间都投入了研究，没有时间看电影了”。前半句的逻辑主语是all her time，与主句主语the scientist 不一致，因此为独立主格结构。time 与devote之间是被动关系，构成devote all her time to doing...结构。综上，D选项正确。
