   • 错误: stoped → 正确: stopped

2. did 和 didn't 后面的动词:

   • 易错点: did 后面必须跟动词原形！

3. was 和 were 的使用:

   • 根据主语的单复数来选择。
   • 错误: I were happy. → 正确: I **was** happy.
   • 错误: They was at home. → 正确: They **were** at home.

4. 一般疑问句的回答:

   • 用 did 提问，回答用 did 或 didn't。
   • 用 was/were 提问，回答用 was/were 或 wasn't/weren't。
   • 错误: Did you have fun? - Yes, I was. → 正确: Yes, I **did**.

5. 时间状语:

   • 一般过去时通常和表示过去的时间状语连用，如：
     • yesterday (昨天)
     • last night / week / month / year (昨晚/上周/上个月/去年)
     • ...ago (...以前，如 two days ago)

学习方法建议

1. 死记硬背不规则动词表: 这是学好本单元的基础，可以每天背10个,反复滚动复习。
2. 多做句型转换练习: 把肯定句、否定句、疑问句、特殊疑问句互相转换,是掌握语法的最好方法。
3. 开口说，动手写: 尝试用一般过去时描述你昨天做了什么，上个周末做了什么,或者写一篇简短的日记。
4. 整理错题本: 把自己常犯的错误（如动词拼写、did后面跟原形等）记录下来,时常翻看。
