usedto

used to 是一个常见的英语表达意思是过去常常。

它用于描述过去的重复动作、习惯或者长时间发生的状态或事情。

比如‘I used to play football after school’意思是我过去放学后常常踢足球‘I used to live in Japan’表示我曾经住在日本。

要注意used to 在否定形式中我们要加上‘did not’或者‘didn't’比如‘I didn't use to play football’。

但在否定和疑问形式中不在‘used’结尾加上‘d’。

例如‘Did you use to watch cartoons when you were a child?’是正确的而‘Did you used to watch cartoons when you were a child?’是错误的。

再比如‘I used to be a good student at school.’是对的‘I used to was a good student at school.’和‘I use to be a good student at school.’都是不对的。

大家在使用 used to 时一定要注意这些要点就能准确表达过去的情况啦。
