英语 so 与such.的用法

Answer 1

一、举几个例子：
such与so的意思都是“如此，这样”。但两者用法根本不同，与what和how引导的感叹句相类似。

1、such后面主要是修饰名词。即：such＋a/an＋adj.＋n.或a/an＋such＋adj.＋n.。如果名词是不可数名词或复数名词，则不可以用不定冠词a或an。如：

①He has such a beautiful bike. We all go to see it.

②It's a such fine day. We al want to go to fly a kite.

2、so后面只能跟形容词或副词。即：和so＋adj.或adv.不过，so后面也可以跟名词，但该名词必须是单数可数名词。用法为：so+形容词+a或an+单数可数名词。如：

①The tiger is so big. And the cat is so small.

②She is so lovely a girl.

3、它们后面还可以与that从句连用。即：such…that和so…that意思是“如此……以致……”。如：

①She is such a clever girl that she can make much progress in math exam.

②His brother is so young that he can't go to school.

注：当名词前的形容词为表示数目的词时，such必须换成so。如：

①There are so many people that we can't go past.

②I ate so much food that I didn't want to go any farther.

注意这一句话：He is such a little boy that he can't read or write.(这一句话中的a little不是“一点”的意思，而是“一个小的”的意思，所以，前面仍然用such，而不用so。

二、再给你分类一下：

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后面直接跟形容词或副词，such后面应先跟冠词a an 之类的再加形容词的等成分
举个例子吧：so nice a girl such a nice girl

So 接形容词，such用于接名词

Answer 4
