--- We have disagreements and we haven’t talked to each other for a long time.

A．are used to

B．are used for

C．are used as

D．used to

Answer 1

D

试题分析：be used to sth习惯于某事;used to do sth过去常常做某事.句意:你为什么不向他去求助？你们过去是好朋友啊！——我们有分歧并且我们有好久不说话了。故选D。
点评：used to用法比较固定，需要注意use还可以作为被动语态使用，sth be used to do sth某物被用来做某事。
