What a difficult problem! Could you tell me____? A.how I can solve it B.how to do with it

A
宾语从句用陈述语序,
B 改为 what to do with it / how to deal with it你好我还想请教你一个问题可以么？what to do with it / how to deal with it 有什么不一样呢为什么选不同的疑问词呢谢谢关键是 do 是及物动词，deal 是不及物动词。what 作 do 的宾语，deal 因为是不及物动词，不加宾语，而 how 是疑问副词，正好不能作宾语。虽然选了不同的疑问词，但含义是一样的。类似的还有：What's the weather like? = How's the weather?也是用不同的疑问词，但含义是相等的。
