such as to和so as to的区别

Question

如题所述

Answer 1

such as to在这里是代词，有“这样，这种,如此（地步）”的意思，as to:以至于，按着。连起来有点这个意味：这样以至于...。常用于表示强调，夸张的语气中。
例句：This book is such as to interest me a lot.这本书是这样的,以至于引起了我的兴趣。（注意这句话读的时候要这样读,This book is such先停顿一下,再连下去读as to interest me a lot.）

so as to有“in order to”的意思，即“为了....”
例句：
Mail your package early so as to ensure its timely arrival.为了保证能按时到达请早点邮寄你的包。
I get up early so as to arrive at school on time.我很早起床以至于准时到达学校。

such as to的这个词组里,such是做代词,而so as to 里面,so不能做代词成分。
