percentage和percent 有什么区别？

区别：

Percentage是抽象的，前面可有形容词修饰如significant，large等，表示一定比例。

Percent 前一般有具体数字，是具体的，表示具体比例。

1.读音：

Percent：英 [pə'sent]美 [pɚˈsɛnt]

Percentage：英 [pəˈsentɪdʒ]美 [pərˈsentɪdʒ]

2.释义：

Percent：百分比，百分数;百分之一

adj.百分之…的，每一百中有…的;百分之…支付利息的。

adv.以百分之…地，每一百中有…地

Percentage：百分比，百分率;比例，部分;[数]百分法;手续费。

3.例句：

Percent：

（1）Drunk driving fatalities have declined more than 10 percent over the past 10 years.

酒后驾车死亡人数在过去10年中下降了10%以上。

（2）The net income per head rose by about 16 percent in the past three years.

在过去的三年中每人的净收入增长了大约16%。

（3）There is a Green party but it only scored around about 10 percent in the vote

虽然有一个绿党，但在选举中该党只得到了大约10%的选票。

Percentage：

（1）Only a few vegetable-origin foods have such a high percentage of protein.

只有几种蔬菜食品有如此高的蛋白质含量。

（2）The percentage of girls in engineering has increased substantially.

学工科的女孩的比例已经大大增加了。

（3）The percentage increase in reported crime in England and Wales this year is the highest since the war.

今年英格兰和威尔士报道的犯罪增长率是战后以来最高的。

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.

percentage注重的是比率，percent说的是有几个百分点，这是个人观点啊。

Percent

A "percent" is always a specific number, amount, or quantity, such as 5 percent or 100 percent.

"Percent": Usage rules:

Never spell out the number in front of the word "percent", even if you would normally spell it out. For example, "5 percent" is correct, not "five percent".
Always use one space between the number and "percent". For example, "5 percent" is correct, "5percent" is incorrect.
Spell out "percent" as one word, never "per cent" or "per ¢" or "%".
"Percent": Exceptions to the Usage Rules (Pesky, but Necessary)

It's okay to use the symbol "%" in tables and highly technical materials where the term comes up repeatedly.
Or, if it is mandated in your house style guide.
Or, if it is used directly in or on a product, such as a user interface, that you are documenting.
