As的用法小结（一)、as作连词的用法：1.作“在…期间，当…的时候”引导时间状语从句.注意与when、while的用法区别。
①下列情形时,只用as，而不用when或while。

4)接名词表示某一个年龄段时.如：As a young man, he was active in sports.As a little boy （When he was a little boy) he began to learn to play the piano.②when作”当……的时候”解,可以指较短的（一点)时间，也可指一段时间。

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。

其基本结构为：as+ adj./ adv. +as。
例如：(1)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。

(2)as...as usual/beforeShe looks as pretty as before.她看起来和以前一样漂亮。

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：(1)It was snowing when he arrived at the construction site.他到达工地时，天正在下雪。
(2)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。
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：(1) Although he is quite old, he still jogs every day.他虽然年纪相当大，仍然每天慢跑。
(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。
(3) However hard he may try, he will not attain his goal.无论他怎样努力也达不到目标。
二、as作关系代词的用法关系代词as引导定语从句时，既可以单独使用，也可以与其他词连用，其用法要比that和which更为复杂。
1. 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。
2. 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)三、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。
四、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。
二、marry一般不说marry sb to sb.marry with是语法错误.marry后面直接跟宾语.would u like to marry me?当用被动形式时,有时相当于一个形容词.I am married.表示我是已婚的（已经被人嫁／娶了我）I get married to sb. 也可以.---再次强调,不能用get married with her(你是因她而结婚?你结婚是为你了自己和你的对象,不是为了别人.说不过去).get married to her.三、join是"加入"的意思而"join in"是"参加"的意思例如:参加党(join in the Party)还有"take part in"也是"参加"的意思例如:参加歌咏小组(take part in the singing group)还有"enter for"是"报名参加"的意思例如:报名参加数学竞赛(enter for the maths contest)当join和join in当“参加”讲时。
join表示参加某一团体、组织、机构，并作为其中一员（如：入党、入团、入会、参军等）e.g.He joined the Labour Party/this company in 1999.他1999年加入了工党/这家公司。
join in: to take part in an activity 参加(活动)e.g.We all joined in the singing.我们大家一起唱歌。
另外：join也有to take part in an activity的意思但join后接的名词似乎更加抽象e on in and join the fun!快进来一起完吧！enter for 是报名参加的意思。
（enter这个词有登记的意思）e.g.He entered himself for the exam.Attendattend39 vt.①出席，参加②照顾，护理vi.(与to连用)①专心于，致力于②照顾经典例句After sleepless nights and long hours of backbreaking work, the prisoners were forced outside to attend roll-calls which lasted for hours.在无数不眠之夜和长时间高强度工作之后，囚犯们还被迫进行几小时的露天点名。
词汇辨析join, take part in, attend, enter：join 参加，加入，成为……的一员；take part in 参与，参加某种活动；attend 出席，参加，定期去（某处）；enter 加入，开始从事；开始参加。
