问题补充：

Jane has been so to getting used to everything that she hasn’t had time for social activities.

A. confused

B. worried

C. devoted

D. based

答案：

A. confused

B. worried

(答案→)C. devoted

D. based

解析：考查固定词组。固定词组be devoted to…致力于…，忙于…；这里的to是介词，后面接动名词或者名词作宾语。其它的形容词不能与介词to连用。句意：Jane一直都在忙着适应这里的一切以至于她没有时间参加各种社交活动。故C正确。
