英语词汇percent的意思、翻译、用法及例句-英语用法大全

percent

☞percentn. [pǝ′sent]　(percents)

双解释义

S 百分之…，百分比 one part in every hundred, percentage

基本要点

1. percent是可数名词，但通常用单数形式，它的基本意思是“百分之…”，非正式英语中可指“百分率”“百分比”，常用符号%表示。与数词连用时，数词应置于percent之前。
2. 在英式英语中， percent的复数形式可表示“有特定利率的证券”“利率为…厘的债券〔公债〕”等。
3. percent of...作主语时， of后如为不可数名词，谓语动词用单数形式；如为可数名词复数形式，则谓语动词用复数形式。
4. increase the rate from three to five percent有两种含义：一是指现在为3%，将来增加到5%；另一种含义是指3%到5%之间的任何一个百分数。为避免误解，前者最好写成from 3% to 5%；后者最好写成by 3—5%。
