Question

so和such的区别。英语学霸请进来。。。。。。。

Answer 1

① 两者都可用作adj.
such作形容词时，无比较级和最高级, 遇不定冠词 a(n) 时, 要放在该冠词之前; 遇 all, no, one, few, several, some, any 等时则放在其后，意为“这样的；那样的”；so作形容词时, 意为“真的；属实的”。如：
One such dictionary is enough.   
If what you say is really so, I'll have to change my plan. 
② 两者都可用作pron.
such作代词时意为“这样的人; 如此的事物”，置于句首时用倒装结构；而so常用作 say, speak, think, hope, expect, suppose, imagine等动词的宾语。如：
He wrote to her every day, such was his love for her.
If you say so, I'll have to believe it. 
注意: a. so用来代替表语或谓语, 使用倒装语序，表示“后者也一样”。如：
Mary can speak Chinese, so can her brother. 
b. so代替上文提过的形容词、名词、动词等, 表示“那样的；的确”，用陈述语序。如： 
（2005安徽） —Maggie had a wonderful time at the party.
—________, and so did I.
A. So she had         B. So had she         
C. So she did         D. So did she
此题选C。So she did 译为“她的确玩得很高兴”； so did I译为“我也玩得很高兴”。
③ 两者都可用于“such / so... as”结构，意为“正如……那样”。其区别是such 修饰的中心词是名词，而so修饰的是形容词或副词。如：
Such people as you've described are difficult to find.
People are not so honest as they once were.
④ 两者都可用于“such / so... as to”结构，意为“如此……以至于”。而so as to则表示目的，意为“为了；目的是……”，相当于in order to。如：
We left for the station so early as to catch the first train.
