        1. We _________ six days a week, but now we only work five days.
          A.used work B.a(chǎn)re used to work
          C.used to workingD.used to work
          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. sth be used to do sth某物被用來做某事。句意:我們過去常常一周工作六天,但是現(xiàn)在我們只工作五天。結合語境可知選D。
          點評:used to的用法比較固定,需要注意的是used to do表示過去常常做某事,be used to表示習慣于某事。前者to是不定式符號,后接動詞原形。后者to是介詞,后接名詞或者名詞性短語。Used to do結構中use相當于行為動詞,有詞形變化。Be used to中used相當于形容詞,無詞形變化。
