用法說明

How is "Percent" different from similar structures?What usage mistakes are common with "Percent"?

percent of 與 percent 單獨使用

  • percent of + 名詞 用於指定一個特定的群體或總量。此時 percent 是名詞,後面需接介系詞 of
  • 單獨使用 percent 時,通常前面已有數字,並作為副詞或名詞使用,修飾動詞或作為主詞/受詞,不直接指定群體。
  • 在比較句中,percent 單獨使用常表示「百分比點」的差異。
  • 當主詞是 percent of + 複數名詞 時,動詞通常用複數形式;若 percent of + 不可數名詞/單數名詞,動詞則用單數。 EN: Thirty percent of the students have passed the exam. 翻譯: 百分之三十的學生通過了考試。

EN:The interest rate increased by two percent.

翻譯:利率上升了百分之二。

總結建議

在指「某群體中的百分之…」時,務必使用 percent of 來連接群體;若僅描述百分比數值或變化,則單獨使用 percent 即可。
