今天聊聊何时使用名词后缀-tion, -sion,和 -cion.

这三个后缀都是用来构成名词的.

最常用是tion和sion，后缀cion不是经常用

1. -sion发 ZH 音

例句：Harry hates to miss his favorite television program.

需要知道的是后缀sion有着不同的发音，在元音后发短u音，在有些词里,s发ZH音

假如你听到"Zhun"音，那就一定是sion结尾

以下是常用的例子:

  • collision

  • division

  • explosion

  • decision

  • seclusion

  • revision

  • confusion

  • conclusion

  • occasion

  • vision

  • invasion

  • exclusion

  • precision

  • fusion

  • persuasion

  • intrusion

2. 在字母L,N,R后的sion

例句：The class will go on an excursion to a sports camp.

如果词尾是l,n,r，那后缀用sion.

在字母r后，发zh音，在字母l或n后，发Shun音

例子：

  • compulsion

  • expulsion

  • propulsion

  • extension

  • tension

  • apprehension

  • expansion

  • pension

  • mansion

  • comprehension

  • dimension

  • suspension

  • diversion

  • immersion

  • version

  • conversion

3.以字母组合mit或ss的用后缀sion

例句：The teacher gave the students permission to take a break.

单词的后缀是mit或ss，我们用sion做后缀。.

举例，动词permit 转成名词permission, express转成名字expression.

以下是相关例子:

  • commission

  • discussion

  • session

  • recession

  • profession

  • mission

  • admission

  • passion

  • depression

  • succession

  • transmission

  • submission

  • emission

  • aggression

  • concession

  • compassion

  • percussion

4.除字母l,n,r以外，后缀用tion

例句：Pauline had a question about the new system.

除字母l,n,r外，后面用后缀tion

以下是例子:

  • information

  • education

  • position

  • action

  • section

  • situation

  • condition

  • production

  • population

  • application

  • operation

  • election

  • association

  • station

  • function

  • organization

  • direction

  • competition

  • institution

  • solution

  • communication

  • protection

  • option

  • contribution

  • reaction

5.例外 ：在字母n或r的加后缀tion

例句：The telephone was a very important invention of the 19th century.

还是有一些在字母n,r后也加后缀tion,这些是例外

举例:

  • mention

  • attention

  • intention

  • convention

  • prevention

  • detention

  • proportion

  • assertion

  • distortion

  • exertion

  • extortion

6. -cion

例句：The detective had a suspicion about the tall woman.

只有极少的单词是以cion结尾的，记忆下就好

它们是:

  • suspicion

  • coercion

  • scion

总结：

名词后缀tion,sion,cion的用法:

  1. 1. 后缀tion,sion比较常用，只有极少单词是以cion做后缀

  2. 2. 如果后缀发Zhun音，拼写就是sion, 当然sion也可发Shun音

  3. 3. 假如基础名词的最后一个字母是l,n,r, 则用后缀sion, 只有少许例外，接tion.

  4. 4. 后缀sion接在以mit或ss结尾的单词后.

  5. 5. 除了基础名词的最后一个字母是l,n,r， 都接tion,发Shun音
