The old man ________ sit like that for hours, and now he is still used to sitting like that．
A. had to
B. was to
C. used to
D. would

Answer 1

答案C
此题中used to与would都可以表示过去的习惯动作或状态，但两者有以下区别：
(1)used to有较强的今昔对比的意味，而would没有．如：
This sort of novel used to be very popular．这类小说过去风行一时．
(2)used to表示过去的习惯动作和情况，would只能表示过去重复的动作．如：
Life is not so easy as it used to be．这里的生活不如以前那样容易了．
He would cycle to school on fine days and would take the bus when the weather was bad．天气好的时候他总是骑自行车上学，在天气不好的时候就坐公共汽车．所以本题答案应是C．
