be used as与be used for,be used to sth./doing sth,be used to do sth.的区别:
be used as和be used for都意为"用作",不同的是as后通常接名词,for后多接v.-ing;be used to sth./doing sth.意为"习惯于某事/做某事",to在这里是介词;be used to do sth.意为"被用于做某事";used to do 意为"过去常常做某事",used to这里是助动词:e.g.
①During the war the castle was used as a prison.战争期间城堡用来作监狱.
