问题补充：

Students are encouraged control of their own learning， rather than just on the teacher.

A. to take， depending

B. taking， depending

C. to have taken， to depend

D. having taken， having depended

答案：

(答案→)A. to take， depending

B. taking， depending

C. to have taken， to depend

D. having taken， having depended

解析：根据 encourage sb to do sth 这一句式可知，第一空应填不定式，故可排除 B 和 D；再根据 encourage 的句意可知，第一空应填一般式，而非完成式，因为“鼓励某人做某事”中的“做某事”肯定发生在“鼓励”之后。
