Question

He is used to _________ the matters that I don’t know _________．

1. A.
   dealing with; what to do with them
2. B.
   dealing with; how to deal with
3. C.
   do with; what to do with
4. D.
   do with; how to deal with them

Answer 1

B
根据be used to后接动名词，可以排除后两项。本题包括一个定语从句，关系代词that在句中充当with的宾语，故them是多余的。句意：他习惯处理一些我不知道怎样处理的事情。
