文字内容来于听力，逗号断句是后配的：
So this is one way to think about Thoreaus text, not just as an important book in its time, for what it tells us about the nineteenth century, but also as a text that can teach us certain things about ourselves in contemporary society.
有几个问题需要请教老师：
问题1、to think about Thoreaus text我理解成one way的定语，但脑袋里的思维是应该理解成“这是一个考虑Thoreau文本的办法”还是理解成“这是一个办法去考虑Thoreau的文本”呢？由于这句话是听力内容，顺着音频听下来，我会直接理解成后者，但后者更像把to think about Thoreaus text理解成了目的状语，我不了解这种误差对我的听力理解是否会有影响，还是说“to think about Thoreaus text”本身就是目的状语呢？
问题2、这里两个as请问如何理解，是理解成方法状语，as是连词后面省略了句子成分吗？但我不了解省略了什么成分。还是说as理解成“作为”“像”这种介词意思。这里我没理解。
问题3、not just...but also在本文里的使用方法要如何理解呢？之前看到的使用方法大多在一句话里，结构也非常明确，但这里的使用方法我却见的极少。
问题4、for这里要如何理解呢？是“对于”的意思还是“由于”的意思呢？是状语还是定语？
问题有点多，期望老师不要嫌弃。

【剖析】使用奥卡姆“简单高效思维原理”，大家简化结构：
1. think about A as B = think of A as B：把A 看作B
语法书一般把这种结构中的as 词组，看作宾语补足语。
2. 填入本句：think about Thoreaus text as an important book,as a text
扩展本句：think about Thoreaus text, not only as an important book, but also as a text
3. not only..., but also... 一般的使用方法是：连接两个并列的成分，只须并列即可。
4. for 是介词，表示“缘由”。 即：what it tells us about the nineteenth century，是把Thoreaus text 看作为 an important book 是什么原因。
