--- 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
答案
答案：D
题目分析：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。
