问题补充：

—What are you going to do this afternoon？ —Im thinking of to visit my aunt．

A. go

B. going

C. to go

D. to going

答案：

A. go

(答案→)B. going

C. to go

D. to going

解析：介词后面要接动名词作宾语，故该题选B。但在介词but/except（除了）后要接不定式作宾语，当but/except前有行为动词do的各种形式时，后接不带to的不定式；如果没有动词do的各种形式，则接带to的不定式，例如：1）They have nothing to do but go to sleep．2）He has no choice but to wait．
