问题 Since it is too late to change my mind now, I am______to carrying out the plan.

选项 A、obliged
B、committed
C、engaged
D、resolved

答案B

解析 从搭配来看,be engaged in sth.或doing sth.“从事某事”或“忙于做某事”;re—solve on sth.“决定做……”,resolve against sth.“决定不做……”;be obliged可以接to,但to后面通常接sb.,即be obliged to sb.for sth.“为某事而感激某人”,或beobliged to do sth.“有义务做……”,但to后面接不定式,而题句中的to是介词;becommitted to sth.(to doing sth.)“承诺做……”,如:I have been committed to help—ing him.我已保证要帮助他。He was committed to supporting his brother’s children.他答应负责养育他的兄弟的孩子。所以无论从习惯搭配,还是从语义上看,committed是正确的。题句意为:既然已经太晚了不能改变主意,那么我保证执行这个计划。
