【重点词汇】浅谈as的用法
来源:网络 文章:匿名 2009-03-24 10:46:5 在中学英语课本中, as 多次出现。它的含义较多,且用法灵活。现将其用法分析归纳如下:
1. as 作为副词,常与连词 as 连用,意为“和??一样”。例如: as easy as ABC (非常容易), as cool as cucumber (沉着的), as stubborn as a mule (非常顽强的,倔强的), as clear as crystal (非常透明的), as poor as a church mou (非常贫困的), as busy as a bee (非常繁忙的)。在这些短语中,第一个 as 是副词,第二个 as 是连。在否定句中,作副词用的 as 可以用 so 代替。例如:
It's not so easy as I thought. (这不像我想的那么容易。)
2. as 作为连词,其意义和用法主要有:
why did you do it
提高记忆力的食物
hit and run( 1 )意为“当??之时”,引导时间状语从句,在意思上相当于 when 和 while 引导的时间状语从句。例如:
As he grew up, he became silent. (他长大以后,变得沉默寡言。)
( 2 ) 意为“既然,因为”,引导原因状语从句,不过它引导的原因状语从句时所表示的原因不如 becau 引导的从句所表示的原因那么直接和强烈。试比较:
As he wasn't ready, we went without him. (既然他没有准备好,我们就自己去了。)
Becau he was ill, he couldn't go to school. (因为他病了,所以不能去上学。)(原因状语从句表示“不能去上学”的直接原因)
( 3 ) 意为“虽然,尽管”,引导让步状语从句,在意思上相当于 although 引导的从句。 as 引导让步状语从句时,常以下列句式出现:名词 / 副词 / 动词 (原形) / 形容词 +as+ 主语 + 其他成分。例如:
Child as he is ( =Although he is a child ) , he can speak English. (尽管他是个孩子,他却能讲英语。)
Young as you are ( =Although you are young ) , you can do it very well. (虽然你年轻,但你却能做得很好。)
Much as I like it , I'll not buy it. (虽然我很喜欢它,我也不会买。)
Try as he may, he has little h(来自: 小龙文 档网:初中英语单词用法大全)ope to win. (尽管他会尽力,但取胜的希望却很小。)( 4 ) 意为“如,像”,引导方式状语从句。例如:
You must do as I tell you . (你必须按照我告诉你的那样去做。)
( 5 ) 意为“作为??(某种身份),当做,视为”。例如:
As a student, you must obey the rules. (作为学生,你必须遵守纪律。 )
3. as 作介词,意为“如同,作为”。例如:
Unite as one man. (团结得像一个人。)swiftcode是什么意思
clo to you卡朋特as 还可以用于 regard , view , treat , acknowledge 及类似意义的动词之后,构成固定搭配。例如:
Most of us regard him as a kind man. (我们大多数人认为他是个好心人。)
We treat them as our friends. (我们把他们当作朋友。)
4. as 用作关系代词,引导非限制性定语从句,并在从句中充当主语、宾语或表语等,有“正如??”或“据??”的意思;它所引导的从句位置较灵活,可以位于句首、句中或句末。例如:As we know from his accent, he is from Shanghai. (正如我们从他的口音中所知道的,他来自上海。)(从句位于句首)
Mary, as we had expected, pasd the exam. (正如我们所预料到的,玛丽通过了考试。)(从句位于句中)
as 还可以引导限制性定语从句。若先行词被 the same , such 修饰,关系代词应用 as .例如:This is such an interesting book as everybody likes to read. (这是一本有趣的、每个人都喜欢看的书。)( as 在从句中作宾语)
This is such a good book as will help you in your study. (这是一本对你学习有帮助的好书。)( as 在从句中作主语)
He is not such a kind boy as he looks. (他看上去地个善良的男孩,实际上却不是。)( as 在从句中作表语)
You must show my wife the same respect as you show me. (你必须尊重我的妻子,就像尊重我一样。)( as 在从句中作宾语)
需要注意 as 引导定语从句时与 so/such??that 引导的结果状语从句的区别。试比较:
This is such an interesting book as everybody likes to read. ( as 引导定语从句,代替先行词 book ,在从句中作宾语)
This is such an interesting book the everybody likes to read it . ( that 引导结果状语从句,因为从句中 read 后面有代词 it宾语。)

一. one可以代替前面刚提到过的同一类人或物,其复数形式为ones.例如:
I haven ' t got a pen. I ' ll have to buy one.(我没有钢笔,我必须去买一支。)
I have a new story-book and veral old ones.(我有一本新的故事书和几本旧的故事书。)
二. 如果one不带任何前置修饰语,而是单独使用时,其意义通常是泛指的。例如:
excited的音标I have no recorder. I want to buy one.(我没有录音机,我想买一台。)
三. 不定冠词a/an不可直接和one连用,但a/an后面有形容词时,可以和one连用。例如:Have you any knives? I need a sharp one.(你有小刀吗?我需要一把锋利的。)

五. one 只能代替可数名词,如果所代替的是特指的不可数名词,那就不能用“the one”,而应该用that.例如:
The study of English is as important as that(=the study)of Chine.(学习英语与学习汉语一样重要。)
六. one(s)通常不用在名词所有格和形容词性的物主代词之后。例如:
