20页UNIT 3 Our HobbiesTOPIC 1 What’s your hobby?Section B--used to 句型“used to + + 动词原形”表示过去存在某种状态或者过去的某种经常性、习惯性的行为或者动作,并意味着这种动作目前已经不存在其中的 to 是不定式符号,而不是介词,所以其后只接动词原形(不能接动名词)Grammar:I used to collect baseball cards. But now I am interested in basketball.Sentence 1:我过去收集棒球卡片现在我对篮球感兴趣我过去收集棒球卡片现在我对篮球感兴趣I used to like dancing.

但现在我喜欢踢足球 used to 通常不能与表示具体次数(如 twice, three times 等)或一段时间(如 three days, five years 等)的词或短语连用,但是它却可以与 always, often ,never等程度副词连用,仍然表示是过去的习惯,不是指现在的习惯,所以不能用一般现在时例如:He always used to be late for class. 他过去常常上课迟到注意:陈述句的肯定形式: 主语+used to+动词原形 I used to play with my friends after school. 过去放学后我常常和朋友们一起玩句型转换:否定形式:主语+didn’t+use to+动词原形 You didn’t use to like pop songs. 你过去常常不喜欢流行歌曲句型转换:一般疑问句形式: Did+主语+use to+动词原形+其他?(肯定回答用Yes, sb. did;否定回答用No, sb. didn’t) Did your sister use to be quiet? 你的妹妹过去常常是很安静吗?句型转换:特殊疑问句含有used to的特殊疑问句的结构为“疑问词+助动词did+主语+use to do...?” —What did you use to do? —I used to collect stamps. 句型转换:used to可以用在there be结构中表示“过去经常有”的意思 There used to be a cinema here. 以前这里曾有家电影院。
