学习建议

1. 语境中记单词： 不要孤立地背单词表，把单词放到句子和对话中去理解和记忆，记 aquarium 时，就记 We went to the aquarium and saw many fish.

2. 掌握不规则动词： 制作一个“不规则动词表”，每天背10-15个，循环复习，直到滚瓜烂熟。

3. 句型操练： 反复练习本单元的核心句型，特别是 Where did you go...? 和 Did you...?，可以和同学进行一问一答的对话练习。

4. 时态对比： 将一般现在时和一般过去时进行对比，理解它们的区别。

   • 一般现在时：I **go** to school every day. (习惯性动作)
   • 一般过去时：I **went** to the park yesterday. (过去某一天的动作)

5. 学以致用： 尝试用英语写一篇简短的日记，描述你上周末或上次假期做了什么，这是检验和巩固学习成果的最好方法。

Last weekend, I went to the countryside with my family. The weather was sunny and warm. We visited a farm. I saw many cows and sheep. My sister bought some fresh eggs. We felt very happy. It was a great day!
