定语从句（也称关系从句、形容词性从句），是指⼀类由关系词（英语：relative word）引导的从句，因为这类从句的句法功能多是做定语，所以曾被称为定语从句（英语：attributive clause），这类从句除了可以做定语之外，还可以充当状语等其他成分，所以现代语⾔学多使⽤“关系从句”这⼀术语。下⾯是店铺整理的as引导的⾮限制性定语从句的内容，⼀起来看看吧。
as引导的⾮限制性定语从句
在as引导的⾮限制性定语从句中，连接代词as在句⼦中可以作主语、宾语或表语等，可以指⼈或物。其在定语从句中的位置⽐较灵活，即可以在句⼦前⾯，在句⼦中间或句⼦末尾。常⽤的结构有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。
[注意1]as通常只指整个句⼦的内容，不表⽰部分内容。
[注意2]as引导的⾮限制性定语从句通常指“事先可以预料到的”“料想到的”，表达“好”的⽅⾯。
[注意3]as引导限制性定语从句时，常构成the same…as…; such…as…; so/as …as…等结构。在从句中既可以指⼈、物，也可以指整个句⼦。
[例句]
This is also part of your work, as I told you before. 我曾告诉过你，这也是你⼯作的⼀部分。
The man was a teacher, as was evident from his way of speaking. 从那⼈说话的样⼦可明显看出，他是个⽼师。
Such ideas as he hits on are worthless. 像他那样偶然想起的主意是⽆⽤的。

在⼀些习惯⽤法上，as能兼作关系代词、关系副词，经常引导定语从句。
惯⽤型1：

as引导的定语从句，有时像⾮限制性定语从句⼀样修饰整个主句或者主句的⼀部分，但它的位置⽐较灵活，可以放在被修饰的主句后⾯，也可以放在主句前⾯。
例如：

你能看得出，我们都是学⽣。

英语作业参考答案：
我很想知道这是不是我的过错，如果是，当然我应该向他道歉，如果不是，那是谁的错呢?是他⾃⼰的错吗?突然，我有了⼀个好主意——我可以同他去谈谈。我想他不会拒绝与我交谈的，因为我知道他是⼀个通情达理的⼈。
I wondered whether it was my fault. If it was my fault, of course I should apologize to him. If it was not my fault, whose fault was it? Was it his own fault? Suddenly, I got a good idea that I could have a talk with him. I thought he wouldn't refuse to talk with me because I knew he was a reasonable man.

限制性从句 as引导各类从句进⾏汇总，并具体总结出其特性，及例句：
⼀、as引导原因状语从句
as表⽰“因为”，与because相⽐，较⼝语化，所表达的原因语⽓较弱，所表的原因⽐较明显，或是已知的事实。
例1：As the weather is so bad, we have to delay our journey.
因为天⽓太糟糕，我们不得不推迟旅⾏。
例2：Any new source of energy will be very welcome, as there is already a shortage of petroleum. 任何新型能源都将⼤受欢迎，因为⽯油已经出现短缺。
⼆、as引导⽅式状语从句
as表⽰“按照”，“以……⽅式”，“像……⼀样”，“正如”。
例：Do as the Romans do when in Rome. ⼊乡随俗
注：as在引导⽅式状语从句时，还常出现在⼀个固定的类⽐结构中：(just) as …, so…。这⼀句型表⽰类⽐，基本含义是“正如……，所以……”。
例：Just as virtue is its own reward, so is vice its own punishment.
善有善报，恶有恶报。
三、as引导让步状语从句
as可以表⽰“尽管”，“虽然”，引导让步状语从句，但必须构成倒装。让步状语从句倒装规则有两类：
1、动词原形+as+主语+助动词（may/might, will/would, can/could, do/does/did），主句。
例：Try as we may, we cannot sense directly the television signal sent out from the broadcast station.
尽管我们费了很⼤的劲，也⽆法直接觉察发射台发出的电视信号。
2、形容词/副词/分词/名词（⽆冠词）/介词短语等+as+主语+谓语动词，主句。
例1：Much as I like you, I couldn’t live with you.
我尽管很喜欢你，却不能和你在⼀起⽣活。
例2：Child as he is, he knows to help others.
尽管他是个孩⼦，他懂得帮助别⼈。
四、as引导时间状语从句
as引导时间状语从句多⽤于⼝语，强调“同⼀时间”或“⼀先⼀后”，有时还有“随着”的含义。
例1：As I was going out, it began to rain.
当我出门时，开始下⾬了。（as强调两个动作紧接着发⽣，不强调下⾬的特定时间。）
例2：As time goes on, he will understand what I said.
随着时间的推移，他会理解我所讲的话。
五、as引导⽐较状语从句
as引导⽐较状语从句，其基本结构是as…as。前⼀个as是副词，后⼀个as是⽐较状语从句的连词。否定结构为not so much … as …。
例1：It was not so much the many blows he received as the lack of fighting spirit that led to his losing the game.
与其说是他受到了许多打击，还不如说是缺乏⽃志使他输掉了⽐赛。
例2：Small as it is, the ant is as much a creature as are all other animals on the earth.
尽管蚂蚁很⼩，但是它同地球上的任何其他动物⼀样，也是⼀种动物。
六、as引导定语从句
as引导定语从句时，既可以引导限定性定语从句，⼜可以引导⾮限定性定语从句。区分as引导定语从句和其它从句的关键特征是：as引导定语从句时在从句中做成分，通常做主语或宾语。
1、as引导⾮限定性定语从句。
as引导⾮限定性定语从句，往往指代⼀整句话，通常表⽰“正如”的意思。as引导的⾮限制性定语从句位置相对⽐较灵活，可以位于先⾏词之前、之后或中间。
例：As is known to everybody, the moon travels round the earth.
众所周知，⽉亮绕着地球转。
2、as引导限定性定语从句。
如从句所修饰的名词前有such、the same、as出现，后⾯的定语从句将由as引导，形成as，as，as…as这样的固定结构，译为“和……⼀样”。
例1：I never heard such stories as he told.
我从未听过他所讲的那样的故事。
例2：He’ll repeat such questions as are discussed in the book.
他将重复书中讨论过的问题。
例3：They made the same mistake as others would have made on such an occasion.
他们犯了和其他⼈在这种场合下会犯的同样错误。
