Why not your teacher for advice when you don’t know the problems?

A. ask; what to do with

B. to ask; how to deal with

C. ask; what to deal with

D. to ask; how to do with

答案：

(答案→)A. ask; what to do with

B. to ask; how to deal with

C. ask; what to deal with

D. to ask; how to do with

解析：why not 后面应该跟动词的原形，所以应该用ask；do with和deal with都有处理、处置的意思，但是do with与what 连用，而deal with用副词how来问。所以本题选A。
