很多同学在学习英语的过程中，常常会混淆"common"和"ordinary"这两个词。虽然它们都表示常见或普通的含义，但实际使用中还是有一些区别的。

简单来说，"common"强调普遍存在，经常出现；而"ordinary"则更侧重于平淡无奇，缺乏特色。

让我们来看一些例句：

• Common:

  • English sentence: The common cold is a viral infection.
  • Chinese translation: 感冒是一种病毒感染。(Gǎnmào shì yī zhǒng bìngdú gǎnrǎn.) Here, "common" emphasizes that the cold is a frequently occurring illness.
  • English sentence: It’s common knowledge that the earth is round.
  • Chinese translation: 地球是圆的，这是常识。(Dìqiú shì yuán de, zhè shì chángshí.) Here, "common" means widely known.

• Ordinary:

  • English sentence: He led an ordinary life.
  • Chinese translation: 他过着普通的生活。(Tā guòzhe pǔtōng de shēnghuó.) Here, "ordinary" suggests a life without excitement or distinction.
  • English sentence: It was an ordinary day, nothing special happened.
  • Chinese translation: 那是一个普通的日子，没有什么特别的事情发生。(Nà shì yīgè pǔtōng de rìzi, méiyǒu shénme tèbié de shìqíng fāshēng.) Here, "ordinary" highlights the lack of anything remarkable.

总而言之，选择"common"还是"ordinary"取决于你想表达的侧重点。前者强调普遍性，后者强调平庸性。记住这个区别，你的英语表达会更精准！
