课文原文

**Lesson 10: Not for jazz 不适于演奏爵士乐**

We have an old musical instrument. It is called a clavichord (古钢琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belonged to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father’s.

**参考译文**： 我们有一件古老的乐器。它被称为古钢琴。它于1681年制造于德国。我们的古钢琴放在客厅里。它属于我们家已经有很长时间了。这件乐器是我祖父多年前买的。最近它被一位访客弄坏了。她试图用它演奏爵士乐！她敲键太用力，弄断了两根弦。我父亲很震惊。现在我们不被允许碰它。它正由我父亲的一位朋友修理。

8.2 词汇学习策略

针对不同水平学习者的建议：

初级学习者:

  • 重点掌握高频基础词 (K1): have, old, call, make, buy, try, play, hard, break, touch
  • 学习核心搭配: belong to, play jazz, strike the keys, too hard
  • 建立主题词汇网络（乐器类词汇）

中级学习者:

  • 关注被动语态中的动词形式: called, made, kept, bought, damaged, broken, shocked, allowed, repaired
  • 掌握一词多义: instrument, string, key, play, strike
  • 学习构词法: music → musical, visit → visitor

高级学习者:

  • 分析低频词汇的精确用法: clavichord (历史语境), damage vs destroy
  • 研究同义词的语义差异: repair vs fix vs mend
  • 理解词汇的情感色彩: damaged (客观) vs destroyed (强烈负面)

8.3 拓展词汇活动建议

  1. 词汇网络图: 以”instrument”为核心绘制语义网，连接clavichord, piano, violin, guitar等
  2. 构词练习: 用-al, -or后缀创造新词（nation → national, act → actor）
  3. 搭配造句: 用belong to, be allowed to, for a long time编写句子
  4. 同义替换: 用不同表达改写”The clavichord was damaged”（broken, ruined等）
  5. 文化探索: 了解clavichord的历史，对比现代piano，理解为什么”not for jazz”
