🔊 发音指导

price发音:/praɪs/ [praɪs]

cost发音:/kɒst/ [kɒst]

expense发音:/ɪkˈspens/ [ɪkˈspens]

sacrifice发音:/ˈsækrɪfaɪs/ [ˈsækrɪfaɪs]

发音要点:

  • price:注意"pr"组合和长元音"aɪ"
  • cost:短元音"ɒ"类似"哦"
  • expense:重音在第二音节,注意"x"发/ks/音
  • sacrifice:第一音节重读,"cri"发/krɪ/

💡 顾老师纠音:常见错误:

  • 把price读成"普莱斯"(正确:[praɪs])
  • 忽略expense的重音位置
  • 将sacrifice的"sa"读成"撒"(应为[ˈsæ])
