such...as用于引導定語從句，such...that 用于引導結果狀語從句。如：

I’ve never heard such stories as he tells. 我從未聽過他講那樣的故事。

It was such a cold day that there was nobody on the street. 天氣很冷，街上沒有一個人。

試比較：

He is such a good teacher as we all respect. 他是一位我們大家都尊敬的好老師。(as引導的是定語從句，as 在該定語從句中用作respect的賓語)

He is such a good teacher that we all respect him. 他是那樣一位好老師,以致于我們大家都尊敬他。(that 引導的是結果狀語從句，that在該狀語從句中不充當句子成分，另外注意句中的respect帶有賓語him)
