so...that 和 such...that 怎么选？一个本质区别（so 是副词，such 是形容词）+ 四大结构
引言
so...that 和 such...that 都翻译成"如此……以至于"，中考常考却总有人选错。本质区别只有一个：so 是副词，such 是形容词。
本质：so 是副词，such 是形容词
```text
so 是副词 → 修饰形容词/副词
such 是形容词 → 修饰名词短语
```
```text
The dog is so clever that everyone likes it.
（so + 形容词 clever）
It is such a clever dog that everyone likes it.
（such + a + 形容词 + 名词 dog）
```
四种核心结构
```text
① so + 形容词/副词 + that
The box is so heavy that I can't lift it.
② so + 形容词 + a/an + 单数名词 + that
It is so clever a dog that everyone likes it.
③ such + a/an + 形容词 + 单数名词 + that
It is such a clever dog that everyone likes it.
④ such + 形容词 + 复数/不可数名词 + that
They are such clever dogs that everyone likes them.
```
关键考点：so 和 such 后面冠词的位置不同
```text
so clever a dog （a 在形容词后）
such a clever dog （a 在形容词前）
```
```text
口诀：such 先 a/an，so 后 a/an
```
特殊情况：many / much / few / little 前只能用 so
```text
so many books ✔ 不能用 such many
so much time ✔ 不能用 such much
so few students ✔ 不能用 such few
so little water ✔ 不能用 such little
```
```text
We have so much time that we can finish the work.
我们有如此多的时间，以至于能完成工作。
```

总结
```text
so 是副词，such 是形容词
so + 形容词/副词 + that
such + a/an + 形容词 + 名词 + that
many/much/few/little 前只用 so
