否认句和疑问句中的“used to do”
“used to do”是一个习惯性过去时态,用来描述过去经常做的事情,但现在不做了。
否认句和疑问句中的“used to do”
否定句
否认句通过在“used to”之前添加“not”来形成:
否定句示例: I didn't use to like spicy food.(我过去不喜欢辛辣的食物。) We didn't use to go to the movies very often.(我们过去不经常去电影院。) They didn't use to be so noisy.(他们过去没有那么吵。)
疑问句
疑问句可以通过两种方式形成:
反意疑问句:在陈述句末添加“did you?”或“didn’t you?”来形成反意疑问句。 疑问句示例: You used to love going to the beach, didn't you?(你过去喜欢去海边,对吧?) They didn't use to work this hard, did they?(他们过去没有这么努力工作,对吧?) Wh-疑问句:使用Wh-词(例如,who、what、when)来形成Wh-疑问句。 疑问句示例: What did you use to do for fun?(你过去做什么来消遣?) Who used to live in this house?(过去谁住在这一屋子?)
否定句和疑问句中的注意事项
否定句和疑问句中,“used to”始终与不定式(to do)一起使用。 否定句中,助动词“did”和“didn't”与主语一致。 在反意疑问句中,助动词“did”和“didn’t”与主语相反。
例句
