结构：
肯定句：主语 + used to + 动词原形
否定句：主语 + didn’t use to + 动词原形
疑问句：Did + 主语 + use to + 动词原形？
例句：

根据时间关键词（in the past, now）判断动作的时态。
注意used to与一般过去时的搭配。
例题7：
Q: My town ______ (have) a small park, but now there is a big shopping mall.

例题8（根据短文）：
Q: What is the main difference between past and present transportation

范文片段：
My hometown has changed a lot over the years. In the past, there were small houses and clean rivers. People used to walk or ride bikes. Now, there are tall buildings and buses. However, the air is polluted. I hope we can protect the environment better.
