🔊 发音指导

expand发音:/ɪkˈspænd/ [ik-spand]

unfold发音:/ʌnˈfəʊld/ [un-fold]

发音要点:

  • expand重音在第二个音节,注意"ex"发[ik]音
  • unfold重音在第二个音节,"un"发[ʌn]短音
  • spread注意"ea"发[e]音,类似"spred"
  • open注意"o"发[əʊ]双元音

中文谐音参考:

expand:伊克-斯潘德

unfold:安-佛得

💡 顾老师纠音:常见发音错误:

  • 把expand读成"ex-pand"(正确:[ik-spand])
  • unfold重音错误放在第一个音节
  • 混淆spread的过去式spread与动词原形发音

🎯 用法区别

1. expand vs unfold

The eagle expanded its wings. (强调翅膀张开的大小)
The eagle unfolded its wings. (强调从折叠状态展开)

2. spread vs open

Spread the tablecloth (平铺动作)
Open the newspaper (从折叠状态打开)

3. 抽象用法

Expand one's knowledge (扩展知识)
Unfold a story (展开叙述)

语法注意:

  • expand可接宾语:expand the business
  • unfold可作及物和不及物动词:unfold the letter / The story unfolds
  • spread不规则动词:spread-spread-spread
