二、such as 与其他相似结构的区别

1. such…as与such…that

such ... as 前者用于引导定语从句，such ... that  后者用于引导结果状语从句。如：

I’ve never heard such stories as he tells. 我从未听过他讲那样的故事。

It was such a cold day that there was nobody on the street. 天气很冷，街上没有一个人。

试比较：

He is such a good teacher as we all respect. 他是一位我们大家都尊敬的好老师。(as引导的是定语从句，as 在该定语从句中用作respect的宾语)

He is such a good teacher that we all respect him. 他是那样一位好老师,以致于我们大家都尊敬他。(that 引导的是结果状语从句，that在该状语从句中不充当句子成分，另外注意句中的respect带有宾语him)

2. such as 与 as such

such as 与 as such 两者词序相反，意义区别也很大，as such 有两个主要意思：

(1) 表示“按照某词通用的词义”“根据某词严格的词义”。如：

It’s not an agreement as such, but it will have virtually the same effect as one. 就协议的词义而言，它算不上是协定，但实际上起到了协定的作用。

I can’t call my book a best seller as such but it’s very popular. 我不敢说我的书是畅销书，但可以说很受欢迎。

(2) 表示“就本身而论”。如：

Money as such will seldom bring happiness. 金钱本身很少带来幸福。

Money, as such, does not bring happiness. 金钱本身并不给人带来快乐。

(3) 表示“以某种身份(或资格)”“像所指的人(或事物)那样”。如：

She is a kind woman and is known as such. 她是位好心肠的女人，这是大家知道的。

He is the author of the article, but he does not desire to be known as such. 他是文章的作者，但他不想让人知道他是作者。
