撇号: 缩略形式 vs possessive ’s

定义 / 说明

英语中的撇号(apostrophe)不止一种用途,这也是常见混淆点。它可用于缩写,如 it's(= it is)和 don't(= do not)。也可用于所有格 's,如 the girl's bag。这两种形式看起来相似,但含义不同。最常见错误之一就是混淆 it'sits

关键规则

  • it's 只表示 it isit has
  • 所有关系用 its(无撇号):The company changed its name.
  • 所有格用 'sAnna's bag, the dog's tail
  • 仔细读句子:若能替换成 it is,那就该用 it's
  • 不要把缩写和所有格混为一谈。

例句

  • It's cold today. - 今天很冷。
  • The cat's toy is under the chair. - 猫的玩具在椅子下面。
  • The company changed its plan. - 公司改变了它的计划。
  • It's a good idea. - 这是个好主意。
  • My friend's bike needs a new seat. - 我朋友的自行车需要新座椅。

常见错误

  • Its cold today. -> ✅ It's cold today.
  • ❌ The company changed it's plan. -> ✅ The company changed its plan.
  • ❌ My friend bike is outside. -> ✅ My friend's bike is outside.
