Question

以下句中的as是否引导的是定语从句，如果是，属于定语从句的什么用法，如果不是，则其引导的是什么从句？

（1）As the two brothers GREw up together, they had their share of problems and they would often quarrel.
（2） Then one day, his younger brother wanted to live separate from him, living his own life, as many normal people do.

Answer 1

（1）As the two brothers grew up together, they had their share of problems and they would often quarrel.
as引导时间状语从句，随着……
随着兄弟俩在一起长大，他们也有各自的问题，经常吵架。
（2） Then one day, his younger brother wanted to live separate from him, living his own life, as many normal people do.
个人认为：as+句子：理解为插入语，as译为正如……一样
例子：As you know, the earth goes around the sun.
as many normal people do 正如许多正常人一样
另一种说法：
as引导非限制性定语从句。as在定语从句中作主语、表语或宾语。as代指整个主句，而as引导的这个定语从句是用来补充说明整个主句的，可以放在主句之前或者之后。
as译为：正如……一样
这里是as作从句宾语。

Answer 2

(1) as the two brothers grew together在句中作原因状语从句。as从句比because引导的原因状语从句在意思上要弱一些，译成汉语也会偏弱。

整句译文：（由于）哥俩一起长大，他们对问题有各自的看法并时常争吵。

(2) as many normal people do作比较状语从句，意思是“就像许多正常人做的一样”。

这个句子中间两个逗号隔开的部分是插入语，用以对live seperate from him做解释，句子主干是

his younger brother wanted to live seperate from him as many nomal people do.

整句译文是：后来有一天，他弟弟不想和他住在一起了，他想要有自己的生活，就像许多正常人一样。
