英语单词名词后缀何时用tion,sion或cion,告诉大家一些规则

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

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
