2.as…as结构用于肯定句或否定句，so…as只用于否定句，用来表示“不如……那样……”。值得注意的是：它表示的内容总是前者不如后者。使用副词表示“不相等”的句型中，“not as/so…as…”中的not要和助动词do,does,did等一起放在行为动词前，来构成否定句

3.as…as结构中，若出现名词，一般将名词放在as…as中间。若有形容词作定语修饰单数可数名词，其前的不定冠词a/an，须放在形容词之后。

4.as…as结构中如出现表示倍数的词，应放在as…as结构之前。如：

Our school is four times as large as yours.我们的学校比你们的学校要大四倍。

5.as…as结构后接具体数字时，是表示长、短、高、矮、重、轻等的程度，而不是表示两者的比较。如：

Some stones weighas much as fifteen tons.有些石头重达十五吨。

一、as作连词的用法1.as...as的用法as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+adj./adv.+as。例如：(1)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。(2)This film is as interesting as that one.这部电影和那部电影一样有趣。其否定式为not as/so+adj./adv.+as。例如：This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。若有修饰成分，如twice,three times,half,a quarter等，则须置于第一个as之前。例如：Your bag is twice as expensive as mine.你的袋子比我的贵一倍。2、as引导时间状语从句此时，as译作“当……时候”，可以放在主句之前，也可以放在主句之后。例如：He smiled as he said goodbye to me.他向我道别时微笑了一下。As she was walking in the park,she heard a girl singing.她在公园里散步时，听到一位女孩在唱歌。I sang an English song as I went along the river.我边沿河边走边唱英文歌。3.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：(1)He will succeed because he is in earnest.他一定会成功，因为他很认真。(2)Since you are so sure of it he”ll believe you.既然你对此如此有把握，他会相信你的。(3)As rain has fallen,the air is cooler.因为下过雨，空气比较清爽。4、as引导让步状语从句此时，as译作“尽管”。当as引导让步状语从句时，不把as放在从句的开头，而是将充当从句主要成分的形容词、副词、分词、动词原形或不加冠词的单数可数名词置于前面。（1）将表语放在句首，再将as放在表语和主语之间。例如：Child as he is,he knows quite a lot of things.虽然他还是个孩子，但他懂得很多事情。（2）将状语放在句首，再将as放在状语（副词）和主语之间。例如：Much as she likes,she will not take it.尽管非常喜欢它，但她也不会拿走的。（3）将主动词放在句首，再将as放在主动词和主语之间。例如：Try as he did,he didn’t succeed.尽管他努力了，但还是没有成功。二、as作介词的用法as作介词，意思是"作为"，"以……身份"。例如：He came to China as a tourist five years ago.他五年前以游客的身份来过中国。三、as作副词的用法to the same degree or amount;equally"相同地"，"同样地"。例如：They don”t have as many airplanes.他们没有同样多的飞机。四、as作关系代词的用法as引导英语从句时，在从句中充当主语、宾语、介词宾语或表语，既可以指人，也可以指物。1.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)(2)To shut your eyes to facts,as many of you do,is foolish.对事实视而不见--你们好多人都是如此的愚蠢。(先行词是不定式短语)2.as引导定语从句与其他词连用①用于the same...as结构中This is the same book as I read last week.这本书和我上周读的那本是一样的。②用于such...as结构中I don”t like such books as he recommends.我不喜欢他推荐的那些书。③用于"so+adj.+a/an+n.(单数)+as"结构中I am not so strong a man as I was.我已经没有从前那么强壮了。

as具体用法如下：

1.as用作副词时主要用来表示比较,意思是“像…一样；如同”。可以单独使用，但更多的是用在as...as结构中，其中第一个as是副词，其后可接形容词或副词,也可接其他成分，as前可有状语。第二个as可以是介词,也可以是连词。as用作副词时还可以指事物以同样的方式发生,意思是“和…一样”。

2.as 常做关系代词，如such children as love their books中的as是love的主语。

3.as还可表示原因,作“因为,既然”解，引导原因状语从句，表示不说自明的原因或理由，语气较轻，是附带提及，不加强调。as引导的从句可放在主句之前(表示原因不明显),也可放在主句之后(表示原因明显)。
