percentage和percent用法的区别

Posted 2023-04-03

在表示百分数时可以用percent或percentage
前者用法是:数词+percent+of+sth;这时后面谓语的单复数以percent后面跟的主语为主,例如:
1.2 percent of the apples(这里是复数的可数名词) are(所以用复数) eaten.
2.2 percent of the apple(这里是单数,指的是一个苹果的一部分) is(用单数) eaten.
3.2 percent of the water(这里是不可数名词) is(单数) drunk.
实在
后者的用法是The percentage of +sth+ is,注意这里不管后面跟的是什么词,都用is(这里忽略别的时态)
1.The percentage of the students is 46.
2.The percentage of the water is 46. 参考技术A 在表示百分数时可以用percent或percentage

percentage

|pəˈsentɪdʒ; 美 pərˈs-|

双语解释：

[可数名词+单数/复数 动词]

the number, amount, rate of sth, expressed as if it is part of a total which is 100; a part or share of a whole

百分率；百分比（指一个比率，可以单独使用）

双语例句：

What percentage of the population is/are overweight?
身体超重的人占人口多大的百分比？

A high percentage of the female staff are part-time workers.
女职员中，兼职工作的人占很高的比例。

percent

|pə ˈsent; 美 pər ˈsent|

双语解释：

You use percent to talk about amounts. For example, if an amount is 10 percent (10%) of a larger amount, it is equal to 10 hundredths of the larger amount.

百分之…（不能单独使用，必须与数词一同使用。）

双语例句：

20 to 40 percent of the voters are undecided.
20%到40%的选民还犹豫不决。
We aim to increase sales by 10 percent.
我们的目标是将销售额提高10%。

参考技术C percent的用法：
　　percent的用法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。
　　percent的用法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。
　　percent的用法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。
　　percent的用法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%。
　　percent的用法5：表示“百分比”有两种方式:per cent和percent,前者是英式英语的拼法,后者是美式英语的拼法。
