关于“such as to”和“such that”的区别，综合搜索结果分析如下：
一、基本定义与用法
such as to 引导目的状语从句，表示“如此……以至于……”，其中“to”后接动词原形。例如：
> The weather was so bad that we couldn't go out. （天气如此恶劣，以至于我们无法外出）
such that
引导结果状语从句，表示“如此……以至于……”，其中“that”后接句子（that可省略）。例如：
> The movie was so boring that I fell asleep. （电影如此无聊，以至于我睡着了）
二、结构与成分差异
such as to
结构：形容词/副词 + 名词 + to + 动词原形
例：
> The problem is such as to cause confusion. （问题如此之大，以至于引起混乱）
*注：此处“such”作形容词，修饰“problem”。
such that
结构：形容词/副词 + 名词/名词短语 + that + 句子
例：
> The cake was such that everyone asked for seconds. （蛋糕如此美味，以至于每个人都要求加第二份）
*注：此处“such”作代词，指代“蛋糕”。
三、核心区别总结
| 维度 | such as to | such that |
|------------|-----------------------------------|---------------------------------|
| 引导类型 | 目的状语从句 | 结果状语从句|
| 语法功能 | 表示行为目的或结果（主动意义） | 表示结果或后果（被动意义） |
| 例句对比 | The movie was so boring thatI fell asleep. | The problem is such thatit caused confusion. |
四、易混淆点辨析
that的省略： 在结果状语从句中，such that 的that可省略，如： > The cake was delicious that
与so that的区别：
such that 后接名词/名词短语，so that 后接形容词/副词，例如：
> The weather was so bad thatwe couldn't go out.
> The problem is such thatit needs immediate attention.
五、补充说明
such...that的扩展用法：可接a/an+形容词+单数可数名词、复数可数名词、不可数名词等，例如：
> This is such an interesting book thatwe all enjoy reading it.
与so that的区别：两者均表结果，但so that强调方式（如：He spoke so loudly thateveryone heard him），而such that强调程度（如：The cake was such thatit broke the record）。
通过以上分析，可清晰区分“such as to”与“such that”的用法，并根据语境选择合适结构。
