Question

____was her anger that her face turned red. 为什么用such不用so

Answer 1

这是倒装
这是such that连用的情况,表示..到那种程度以至于..
===
顺便说一下,很少见到such that 连用的情况.只是在口语里偶尔有这样的用法.例如：
The shock was such that he was almost driven mad.
因为打击太大,她差点发疯了.
===
同理,句子正装
===
Her anger was such that her face turned red.
她的火气太大,以至于脸变的通红
所以,如果这里把such换成so,so单独副词出现,而且有不是so..that句型,显然不能用.句子是故意倒装混淆的
===
3点事项
so that 连写的意思是“以便于,为了”.
so 与 such 互换的情况
在上面说到,so...that 结构中,so 后面直接用形容词或副词、分词；such...that 结构中,such 后接名词.这里两者最大的区别.但是,如果such 后面接的是可数名词单数,也可以换成 so.例如：
so clever a boy = such a clever boy
但如果碰到many,much,few,little 这四个词,就必须用so 而不能用such,即：
so many students
so much money
so few students
so little money
so,such 句子的倒装
当so,such 放在句首时,全面的主、谓要进行分倒装.例如：
So badly was he injured that he had to be sent to the hospital.
他的伤势很重,不得不送医院.
In such a hurry did he go to school that he forgot to bring his schoolbag.
他上学时太匆忙了,以致于他忘了带书包.
Such was the force of the eruption that the whole town was covered with ash.
火山爆发的威力大得使整个城市都被火山灰淹没了.
