问题补充：
We still couldn’t decide with our difficulties in learning English.
A. how to do
B. how to deal
C. what to deal
D. what to solve
答案：
A. how to do
(答案→)B. how to deal
C. what to deal
D. what to solve
解析：根据句子的结构，本句已经有宾语了（our difficulties），故不应该用what，故排除CD。另外，虽然do with和deal with都有“处理，处置”的意思，但do with常与what连用，而deal with常与how连用。所以本题选B。
