常见考点与易错点

动词过去式的变化:
（图片来源网络，侵删）
- 不规则动词: 必须牢记，不能按规则变化。go → went, see → saw, eat → ate。
- 规则动词: 大部分动词在词尾加 -ed，但要注意：
  - 以 e 结尾的，只加 -d (e.g., like → liked, visit → visited)。
  - 以“辅音字母+y”结尾的，变 y 为 i 再加 -ed (e.g., study → studied, cry → cried)。
  - 以重读闭音节结尾，且末尾只有一个辅音字母的，双写该辅音字母再加 -ed (e.g., stop → stopped, plan → planned)。
did 和 was/were 的混用:
- did 是助动词，帮助构成疑问和否定，后面跟动词原形。
- was/were 是 be 动词的过去式,本身可以作谓语。
- 错误: Did you were happy? (×)
- 正确: Were you happy? (√) 或 Did you have a good time? (√)
时间状语的混淆:
- 区分 yesterday (昨天) 和 the day before yesterday (前天)。
- 区分 last week (上周) 和 next week (下周)。
- 区分 ago (以前) 和 before (在...之前)。
特殊疑问句的语序:
- 特殊疑问词（What, Where, When, Why）开头的一般过去时疑问句，结构是 特殊疑问词 + did + 主语 + 动词原形 + ...?
- 错误: Where did you went? (×)
- 正确: Where did you go? (√)

单元话题与写作

本单元的核心话题是 "Talk about past events" (谈论过去的事件)。

范文示例：My Last Weekend

Last weekend was interesting. On Saturday morning, I stayed at home and studied for my math test. In the afternoon, I went to the park with my friends. We played basketball and had a great time.

On Sunday, I visited my grandparents. They were very happy to see me. In the evening, I watched a movie with my family at home. It was a funny comedy.

I was a little tired on Monday, but I felt happy. I really enjoyed my last weekend.
