As 是一个很强大的词…

1. as用作连词引导时间状语从句
as与when，while都是引导时间状语从句的从属连词，含义都是"当……的时候"。但它们有区别：用when时，从句的动作可以与主句的动作同时发生，也可以先于主句的动作发生；用while时，从句的动作为一过程，主句动作与从句动作同时进行或在从句动作过程中发生；用as时，主句和从句的动作同时发生，具有延续的含义。例如：

(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。

2. as用作连词引导原因状语从句
as，because，since都可以表示因果关系，连接原因状语从句，含义是"因为，由于"，但它们有区别：because表示的语气最强；as一般放在句首，语气较弱，较口语化；since常常用在书面语中，表示多为对方已知的、或稍加分析便可得知的原因，有时可译作"既然"。例如：

(3) As rain has fallen, the air is cooler.因为下过雨，空气比较清爽。

3. as作连词引导让步状语从句
as与although (或though)，however (或no matter how)等都可以引导让步状语从句，含义是"虽然，尽管"，但它们有区别：although语气稍正式些，可放在句首，也可放在句中，主句中不能再用but，但可以用yet；as所表示的语气较强，引导的让步状语从句用倒装语序；however引导让步状语从句时，它的后面可跟形容词或副词，也要用倒装语序。例如：

(2) Strange as it may seem, nobody was injured in the accident.这次意外虽然显得令人不可思议，却没有人受伤。

4. as单独引导定语从句
as单独引导定语从句时，先行词可以是一个词，也可以是一个句子或短语。例如：

(1) She is late, as is often the case.她迟到了，这是经常的事。(先行词是整个主句)

我不是好学啦…在花费两天时间来校对一篇翻译后…我终于发现导致我效率低下的主要原因就是这个as了…
这个在澳洲的印度人写的论文
让我充分认识到了as的强大….
他可以把任何连词都用as来替代…
已经达到了出神入化的程度…
强烈建议将其论文列入CET题库…
阿门…

试举一段：
Every cuisine in this world has started as an Indigenous one. There are many examples of the Indigenous foods that travelled to other continents to become ethnic food and finally found their place into universal cuisines. The movement of potatoes, corn and chillies from Latin America to Europe, Chinese fowl’s movement to South Americas in the ships of Chinese explorers (Menzies, 2003) are a few examples. Incidentally, potatoes were used as ornamental plants for their flowers and the tuber was forbidden to be eaten as it was supposed to cause leprosy. The same plant was the reason for mass migration of Irish to the US when its crop failed in 19^th century. For a long time, Australian natives lived an undisturbed existence as the predominant cultures of the world did not discover it till quite recently. The Indigenous cuisine of Australia is at the culinary evolution stage what Latin America was till it was discovered by Spanish a few centuries ago. The occupiers of the continent kept well away from the native culture and it is in the Australian history that the initial settlers almost starved as they were not used to local conditions and who tried to cultivate European crops on this land. It is expected that as with other example, with time, the Australian native ingredients will find their way into pantries, lose the ‘exotic’ label and be recognised as normal part of recipes.
