学习建议与技巧

攻克语法：
- 对比学习: 将过去进行时和一般过去时放在一起对比，一般过去时表示一个已经完成的动作，过去进行时表示一个正在进行的动作。
  - I read a book yesterday. (我昨天读完了书。)
  - I was reading a book at 5 pm yesterday. (昨天下午5点我正在看书。)
- 情景造句: 不要死记硬背规则，围绕“昨天这个时候”、“上周六下午”等时间点，多造句描述自己或家人的活动。
积累词汇：
- 分类记忆: 将关于天气、突发事件、情感、地点的词汇分类记忆。
- 短语运用: 重点短语（如 go off, take off, in silence）一定要放在句子中理解和记忆，而不是孤立地背中文意思。
听说读写结合：
- 听: 反复听课本的录音，模仿语音语调，特别注意 was/were 的发音。
- 说: 和同学练习对话，互相提问 What were you doing when...?，分享自己的故事。
- 读: 朗读课文，尝试复述课文内容，用自己的话讲出马丁·路德·金或肯尼迪遇刺时不同人的经历。
- 写: 写一篇小短文，描述一次你经历过的或想象中的突发事件（比如停电、火灾、突然的暴雨等），尽量多地使用过去进行时和本单元的词汇短语。
拓展思维：
- 思考“历史中的我”：如果你生活在那个年代（比如1968年），你会是什么人？在做什么？这能让你更深刻地理解课文内容。
- 准备应急计划：结合课文内容，和家人讨论一下，如果遇到地震、火灾等紧急情况，家庭应急计划是什么。
