英语句子中前面有such的时候后面用that 和 as 区别,如he never hesitate to make such criticism _that_

are considered helpful to others. 这里为什么用that 不用as?不是说as引导限制性定于从局只iyongyu固定结构中,如such as, the same as修饰的先行词后面,儿非限制性定语从句没有结构要求?晕了,两者到底有啥区别啊,谢谢了
还有一些句子,求大侠分析 do not trust such man as praise you to your face.
还有such as , such that so as so that 区别,跪谢

要明白这两种定语从句,首先得从词性和用法说起。
一、such
1. 形容词:这样的,如此的,用于修饰名词,如:
* He has a single parent, one of many such people in the neighborhood. 他是单亲,这地区附近有许多这样的人。
* He has never dreamed of such wealth. 他从未梦想过这样的财富。
2. 不定代词:象这样的人或物,直接用来作主语或宾语,如:
* He expected difficulties, and such occurred. 预期会有困难,而这样的困难果然出现了。
* Such are the fortunes of war. 这些就是战争的机会。
二、as 用作关系代词指代下面或前面提到的一句话,如:
* The statemant reads in full As follows: ... 声明全文如下: ...
(As 作从句谓语动词 follows 的主语,指代 The statemant reads in full,也可以改写为:The statemant reads in full, which follows: ...)
* As you well know,English is an importan tool in communication. 众所周知,英语是交流的重要工具。(as 是从句中 know 的宾语,指代 English is an importan tool in communication这件事)
三、that 也是关系代词,但是与 as 不同的是它只指代先行词,而不能指代句子(例句略)。
四、明白上述道理,such that 和 such as 的区别就会迎刃而解,如:
* He expected difficulties, and such that could be avoided occurred at last. 预期会有困难,而这种可以避免的困难最终还是出现了。(such 是不定代词,指代 difficulties, 关系代词指代 such)
* He expected difficulties, and such avoided occurred as well know to everyone. 预期会有困难,而众所周知,这样的困难果然出现了。

说得比较罗嗦,不知道能否解决你的问题。

so(such)。。。。that用于结果状语从句,而so(such)。。。。。。as用于定语从句。这是定语从句所以用that追问
