问题补充：

----Will you take up teaching as a career after graduation?

---- Hard to say. I go abroad for higher education instead, but it depends.

A. must

B. should

C. might

D. shall

答案：

A. must

B. should

(答案→)C. might

D. shall

解析：句意：--毕业后，你愿意做教师的职业吗？--很难说，我可能会出国深造，但是看情况而定了。从but it depends.可知这件事还没有确定，只是看情况而定，用might，must必须，should应该，shall将会，所以选C。
