Question

--- 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

試題分析：be used to sth習慣于某事;used to do sth過去常常做某事.句意:你為什么不向他去求助？你們過去是好朋友啊！——我們有分歧并且我們有好久不說話了。故選D。
點評：used to用法比較固定，需要注意use還可以作為被動語態使用，sth be used to do sth某物被用來做某事。
