方式状语从句通常由as。(just) as…so…。as if。as though引导。当as引导行为方式状语从句时，意为“如同……”或“按照……的方式(样子,办法)”，这种从句通常位于主句之后。例如，你必须像我这样拿工具，别动这些东西，我们必须按照党的指示办事。在(just) as…so…结构中，as从句位于句首，带有比喻的含义，意思是“正如…”或“就像”，多用于正式文体。例如，你希望人家怎样待你，你就要怎样待人，我们离不开空气，犹如鱼儿离不开水，正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。as if/though引导的方式状语从句比较容易区分，这里不做解释。
当as引导限制性定语从句时，构成“the same。as。”。“such。as。”。“as many (much。few。little)。as。”等结构。as可替代先行词，在从句中作主语、表语、宾语或状语。例如，他不再是过去那个样子了，我从来没有听见过像他正在讲述的这种故事，这里有一瓶纯净水，你需要多少就用多少。
This watch is XXX I lost.
During that time。many young people lived in the same manner as the XXX.
An as-clause。which can modify the entire main clause or a part of it。is a non-restrictive relative clause。It can be placed before。within。or after the main clause and is usually separated from it by a comma。As can be translated as "just as" or "like"。For example。Talks een the two countries are making progress。as is XXX.
I know he is English from his accent.
限制性从句He went for a walk after dinner。as he usually did.
As usual。we have exceeded the n plan this year.
As expected。this machine has XXX.
XXX。as he usually does。It's XXX clause。"as" always has an antecedent (a noun phrase。pronoun。main clause。or part of a main clause)。and it must n as a XXX of this include "as has been said before," "as is ned above," "as may be imagined," "as is well known to us all," "as all know," "as often happens," "as has already been pointed out," and "as we all can see."
In summary。it can be overwhelming to understand the different uses of "as," but it's important to note that in a relative clause。"as" always has an XXX clause。When "as" is used to introduce an adverbial clause。XXX。without any specific n XXX restrictive and non-restrictive relative clauses。which can be identified by the presence or absence of a comma een the main clause and the relative clause.
