初中英语小议as…as…的用法 知识精讲
初中英语小议as…as…的用法知识精讲as…as是形容词或副词比较中用于原级比较的一个重要句型，主要有以下几种用法：一、“as（否定句中可用so）+adj./adv. +as…”，其基本意思为“……和……一样”。
但在实际应用中，此结构在不同的语境中含义差异较大。
1、表示不同人或物同一性质的比较，意为“……和……一样……”。
The tree is as tall as the building(is).这棵树和那栋楼一样高。
2、表示同一个人或物不同性质的比较，意为“既……又……”。
Alice works as happily as(she) plays(happily).艾丽丝愉快地工作、尽情地玩。
3、用于表示两个人或物不同性质的比较，表示程度相同或相当，意为“……而……”。
He was as experienced as his brother was green.他经验丰富，而他兄弟却涉世未深。
二、as…as结构的另一种形式是“as much/many+名词+as+从句”。
It is as much your fault as your wife’s.这既是你的过错，也是你妻子的过错。
三、若有修饰成分，如twice, three, times, half, a quarter等，必须置于第一个as之前。
You are not half as clever as your think you are.你可不像自己想像的那么聪明。
You’ve made just as many mistakes as I have.我和你犯的错误一样多。
四、as…as结构的另一变体形式是“as+形容词原级+名词词组+as”I don’t want as expensive a car as this. =I don’t want a car as expensive as this.我不要这么贵的汽车。
五、当as…as与表示重量、数量、时间、距离、价格等的计量名词连用时，往往并不表示比较，而是构成一个形容词组，意为“重达……，多达……，高达……”等。
初中as的用法归纳总结
初中as的用法归纳总结好嘞，以下是为您总结的初中“as”的用法：咱们先来说说“as”这个词，它在初中英语里可是个相当活跃的角色呢！“as”作连词的时候，有“当的时候；因为；正如”这些意思。
比如说，“As I was walking in the park, I saw a beautiful bird” （当我在公园散步的时候，我看到了一只漂亮的鸟。
）这里的“as”就是“当的时候”。
还有啊，“As she is very busy, she can't come to the party” （因为她很忙，所以她不能来参加聚会。
）这时候“as”就是表示“因为”啦。
“as”也能用来引导方式状语从句，表示“像一样；按照”。
像“Please do as I tell you ”（请按照我告诉你的做。
）“as”作介词的时候，意思是“作为；当作”。
比如“He works as a teacher ”（他作为一名教师工作。
）给大家分享一个我教学时候的小趣事。
有一次，课堂上我让同学们用“as”来造句，有个同学特别积极地举手说：“I want to be as strong asmy father” （我想和我爸爸一样强壮。
）我一听，不错不错，这孩子理解得挺到位。
然后我又让其他同学也来说说，大家七嘴八舌的，课堂气氛那叫一个热烈。
咱们再接着说“as”的其他用法。
“asas”结构大家应该也不陌生，它表示“和一样”。
像“He is as tall as his brother ”（他和他哥哥一样高。
）要注意哦，第一个“as”是副词，第二个“as”是连词。
还有“suchas”和“the sameas”这两个结构。
“suchas”表示“像这样的”，“the sameas”表示“和相同的”。
说起来，我之前批改作业的时候，发现有的同学会把“asas”结构用错，比如写成“He is as taller as his brother” 这可就不对啦，应该是“He is as tall as his brother” 可不能自己乱加比较级哦。

初中时间状语从句语法及练习
英语时间状语从句讲解与练习〔一〕when, while 和as 引导时间状语从句的用法一、when 的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。
1. When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。
2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。
3. Were you writing when the teacher came in? 教师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打来的时候我出去了。
5. He was on the point of leaving when someone knocked at the door.他正要走，这时有人敲门。
6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。
7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。
根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B发生的时间点。
也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，那么不用正在进展时。
因为如果用正在进展时，它表示的就是一段时间而不是一个时间点了。
根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。
这种说法也可以参照。
实际上，when 从句也可以有其它的时态，但几乎也不用进展时，因为它也只是作为一个时间参照点。
as初中用法
as初中用法as在初中的用法主要有以下几种：引导时间状语从句，意为“当……之时”，表示两个动作同时发生。

例如：As he wasn't ready，we went without him.（他还没准备好，我们就自己去了。
）引导方式状语从句，意为“如，像”。
例如：You must do as I tell you.（你必须按照我告诉你的那样去做。
）作为介词，意思是“作为”、“当做”、“成为”。
例如：As a student，you must obey the rules.（作为学生，你必须遵守纪律。
）引导比较状语从句，意为“像…一样”。
例如：She sings as sweetly as a nightingale.（她唱歌像夜莺般婉转悦耳。
）引导让步状语从句，意为“虽然”、“尽管”。
例如：Small as it is，the ant is more powerful than any of the big animals.（尽管蚂蚁很小，但它比任何大的动物都强大。
）用于“as + 形容词/副词 + as”结构，表示对两个比较对象都进行肯定或否定。
例如：The book is as interesting as the one I read yesterday.（这本书和我昨天读的那本书一样有趣。
）用于“as + 形容词 + a/an + 单数可数名词 + as”结构，表示两个比较对象在某一方面相似或相等。
例如：He is as clever a boy as Tom.（他和汤姆一样是一个聪明的男孩。
）此外，“as”还可以表示“虽然”、“尽管”等意思，常用于让步状语从句。
