be used to do和be used to doing

be used to do和be used to doing1、be used to do中be used是被动语态吧(be+done结构)
2、be used to doing中used是过去分词做形容词吧

Answer 1

1）　　be used to do的意思是被用来做某事;be used to doing的意思是习惯于做某事.
be used to 被用来做
used to + do："过去常常"表示过去习惯性的动作或状态，但如今已不存在。

Scarf used to take a walk. (过去常常散步)
2）be used to + doing：;已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。
