八年级上册英语第二单元重点难点有哪些？

核心语法：一般过去时

这是本单元的重中之重,你需要彻底掌握它。

定义

表示在过去某个时间点或时间段内发生的动作或存在的状态,这个动作或状态现在已经结束。

构成

一般过去时的构成分为 be 动词 和 实义动词 两种情况。

句子成分	构成方式	例句
Be 动词	was / were + 主语 + ...	I was at home yesterday. (我昨天在家。) They were happy last night. (他们昨晚很开心。)
实义动词	动词过去式 + 主语 + ...	I watched TV last night. (我昨晚看了电视。) She played the piano yesterday. (她昨天弹了钢琴。)

动词过去式的构成规则（这是重点和难点）

• 规则变化：

  1. 直接加 -ed：
     • work → worked (工作)
     • look → looked (看)
     • play → played (玩)
     • clean → cleaned (打扫)
  2. 以 e 只加 -d：
     • live → lived (居住)
     • like → liked (喜欢)
     • use → used (使用)
  3. “辅音字母 + y”变 y 为 i，再加 -ed：
     • study → studied (学习)
     • cry → cried (哭)
     • try → tried (尝试)
  4. “元音字母 + y”直接加 -ed：
     • enjoy → enjoyed (享受)
     • stay → stayed (停留)
  5. 重读闭音节结尾，且末尾只有一个辅音字母，双写该辅音字母，再加 -ed：
     • stop → stopped (停止)
     • plan → planned (计划)
     • prefer → preferred (更喜欢)

• 不规则变化：这些需要单独记忆,是考试的重点。

  • am/is → was
  • are → were
  • go → went
  • have/has → had
  • do → did
  • see → saw
  • eat → ate
  • take → took
  • get → got
  • make → made
  • read → read (读音 /red/)
  • write → wrote
  • sing → sang
  • swim → swam

肯定句、否定句、疑问句及回答

句子类型	构成	例句
肯定句	主语 + 动词过去式 + ...	He went to the park.
否定句	主语 + didn't + 动词原形 + ...	He didn't go to the park.
一般疑问句	Did + 主语 + 动词原形 + ...?	Did he go to the park?
肯定回答	Yes, 主语 + did.	Yes, he did.
否定回答	No, 主语 + didn't.	No, he didn't.

特别注意：

• 在否定句和疑问句中，助动词 did 后面的动词必须用原形！
• be 动词的否定和疑问变化是特殊的：

Last weekend was fantastic. I had a lot of fun.

On Saturday morning, I did my homework first. Then in the afternoon, I went to the park with my best friend, Tom. We flew a kite and it was very exciting. The weather was sunny and warm.

On Sunday, I visited my grandparents. They live in the countryside. We had lunch together. My grandma cooked delicious food. In the evening, I watched a funny movie at home.

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