such a、such、so的区别为：指代不同、侧重点不同、引证用法不同
一、指代不同
1、such a：这样的。
2、such：如此。
3、so：这么。
二、侧重点不同
1、such a：是一个句子中的节选，后面接名词。
2、such：such后面接名词可在其后接a，an。
3、so：so后面接形容词，副词，不可接a，an。
三、引证用法不同
1、such a：such用作形容词时，常放在不定冠词之前， all， many， few， some等之后，但其前不可用many of等。
2、such：such有时在后面的分句中，对前面的分句加以解释，说明原因，两个分句间用逗号隔开，后面分句比较强调。
3、so：so用作连词可用于表示结果，作“因此，所以”解; 也可用于表示目的，作“为了，以便”解; 还可用以引出一段话进行评比。

such a 后面是要接名词的a 不可能放在such之前
1、so + 形容词/副词 + that + 从句，如： This story is so interesting that I want to read it again. （这个故事如此有趣以至我想再读一次。） He spoke so quickly that I couldn't follow him. （他说得如此快以至我不能跟上他。） 2、so+形容词/副词+(a/an)+(单数)复数可数名词／不可数名词+that+从句，如果句中的名词是单数可数名词，其前就要用不定冠词a或an，如果是复数可数名词或者不可数名词，前面就不用冠词，如： She is so lovely a girl that everyone loves he（这个故事如此有趣以至我想再读一次。）r. （她是如此可爱的一个女孩，以至每个人都喜欢她。） Those are so beautiful flowers that the girl wants to pick them.（那些花是如此漂亮以至那个女孩想要摘下它们。） 3、such+a/an+形容词+单数可数名词+that+从句，如： She is such a lovely girl that everyone loves her.（她是如此可爱的一个女孩，以至每个人都喜欢她。） It is such an interesting story that I want to read it again. （这是一个如此有趣的故事以至我想再读一次。） 4、such+复数可数名词/不可数名词+that+从句，如： He showed such concern that people took him to be a relative.（他表现得如此关心以致于人们都把他当作亲戚了。）

so与such都有“如此、这么、那么”的意思，可进行同义改写，但用法不同。
1. so是副词，修饰形容词和副词；而such是形容词，修饰名词。它们后面接单数可数名词时，词序不同。
so的词序为：so+ adj. + a（an） + n.such的词序为：such +a（an） +adj. + n. so nice a coat =such a nice coat 这么漂亮的一件外套
so interesting a book = such an interesting book 那么有趣的一本书
后面接复数名词或不可数名词时，只能用such，而不能用so.如：
such beautiful flowers 这么美丽的花
such clever children 如此聪明的孩子
但是，复数名词或不可数名词前有many，few，much，little修饰时，只能用so而不能用such，这是一种固定用法。如：so many books 这么多书,so few people 这么少的人,so much money 那么多的钱so little milk 那么少的牛奶
2. 和“that”连用时，意思基本一样，但句型结构不同。“so…that…”句型结构为：
so + adj. （adv.） +that…
so + adj. +a（an）+单数n. +that…
so +many（few）+复数n. +that…
so +much（little）+不可数n. +that…如：
This book is so interesting that I have read it three times. 这本书如此有趣，我已经看了三遍。
He spoke so fast that we couldn‘t understand him. 他说得太快，我们都未能听懂他的话。
It was so hot a day that nobody wanted to do anything. 天气很热，谁都不想干活。
There were so many people that we could hardly move on. 这么多人，我们简直无法继续往前走。
“such…that…”句型结构为：
such + a （an）+adj. +单数n. +that…
such + adj. +复数n. +that…
such +adj. +不可数n. +that…
She is such a pretty girl that everyone likes her. 她是个很可爱的小姑娘，大家都喜欢她。
They are such delicious cakes that I want to eat another two. 这么可口的蛋糕，我还想再吃两块。
It is such sweet milk that we all want to drink it. 这么香的牛奶，我们都想喝。
补给站：由于so 和such后跟单数可数名词时，可以换用，同样“so…that…”与“such…that…”也可以进行同义句改写。如上文中：This book is so interesting that I have read it three times. 可改写成：This is such an interesting book that I have read it three times.
It was so hot a day that nobody wanted to do anything. 可改写成：It was such a hot day that nobody wanted to do anything.
3. so与that可以直接构成词组“so that”，引导目的和结果状语从句，表示“以便、以致”的意思。如：
He worked hard so that he could pass the exams. 为了能通过考试，他学习很认真。（但such没有这种用法）

such为形容词 so是副词 但是 such和so都可以用于名词词组 一、后接可数名词的单数形式
1、直接跟名词时，用such；例如：
However did you make such a mistake?
I have never heard of such a thing.
Why are you in such a hurry?
注意：当such前面有no时，必须省去不定冠词a(an)，因为no such本身已经包括了不定冠词，相当于not such a(an)；例如：
I have no such book. (= I haven’t such a book.)
2、跟带有形容词的名词时，既可以用such，也可以用so，但应注意冠词位置的不同，例如：
I have never seen such a tall man.
I have never seen so tall a man.
He is not such a clever boy as his brother.
He is not so clever a boy as his brother.
二、后接可数名词的复数形式或集合名词，无论有无修饰语都用such，例如：
Such things often happen in our daily life.
Such people are dangerous.
Whales are such smart animals that they communicate with each other.
He made such stupid mistakes that the teacher tore up the whole paper.
三、后接不可数名词，无论有无修饰语都用such，例如：
Did you ever see such weather?
You can’t drink such hot milk.
She made such rapid progress that she soon began to write articles in English.
四、当复数名词或集合名词之前有few，many；不可数名词之前有little，much修饰时，用so，例如：
so many people / so many students / so few days
so much time / so much money / so little time等。
注意：上述词组中的so实际上修饰名词前的形容词。试比较下列两句：
①I have met many such people in my life.
②I didn’t expect to meet so many people there.
上述两句中都有many，但却分别用了such和so，其位置不同，因此含义也不同。在①中，many和such同时修饰后面的名词；而②句中的so修饰的则是many。
五、当many、much、little、few单独作为名词使用时，用so；例如：
There are so few that I can’t give you one.
This is the girl I have told you so much about.
So much for today.
六、such可以和all、some、other、another、one、no、many、any、few、several等词同时修饰一个名词，但它的位置通常是放在这些词的后面，例如：
All such possibilities must be considered.
such a后面+名词词组，eg:such a good boy,such a girl
