重点解析:浅谈as的用法

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 mouse (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:

( 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 because 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。)Because 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 hope 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。)

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, passed 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 作宾语。)

A.found B.finding C.having found D.to find 【答案】D 【解析】考查非谓语动词。句意:学生们上网是为了找到他们理想大学的更多的信息。此处表示目的用不定式,指上网的目的。故选D。 2.Look over there! There is a long, winding path ________ up to the house. A.lead B.leading C.led D.to lead 【答案】B 【解析】 【详解】 考查非谓语动词。句意:看那边!有一条长长的蜿蜒小路通向那所房子。分析句式可知,这是个there be 句型,因此,此处用非谓语动词,path与lead是主动关系,因此用现在分词,故选B。 3.______ to nuclear radiation, even for a short time, may influence genes in human bodies. A.Having exposed B.Being exposed C.To expose D.Exposed 【答案】B 【解析】 【详解】 考查动名词。句意:暴露于核辐射中甚至很短时间都会影响人体的基因。分析句子成分发现even for a short time是插入语,may influence是谓语,前面的部分应该是主语,be exposed to“暴露于”,要用动名词Being exposed to。故B选项正确。 4.The lecture, _______at 7:00 pm last night, was followed by an observation of the moon with telescopes.

Otherwise与定语从句

Learning Corner 学习频道 ◎ 文 / 张满胜 本期我们来分析otherwise 在定语从句中的用法。首先请看2013年考研英语(一)完型填空中的一句话。 This might sound small, but to undo the effects of such a decrease a candidate would need 30 more GMAT points than would otherwise have been necessary. 本句的难点是than would otherwise have been necessary 这一部分,其中的otherwise 用在定语从句结构中,并与虚拟语气搭配使用。之所以要用虚拟语气,是因为otherwise 的基本含义是“在相反的情况下”或“要不然的话”,表达的是与前面提到的真实情况相反的一个假设情形。Otherwise 的这一用法既可以出现在that/which/who 引导的普通定语从句(下文统称为“that 定语从句”)中,也可以出现在than 引导的特殊定语从句(下文简称为“than 定语从句”,关于than 引导的定语从句讲解请见本刊2008年12月号和2009年1~2月合刊)中。下面我们分别来看otherwise 在that 定语从句和than 定语从句中的用法特点。 Otherwise用于that定语从句 would 等情态动词,而相应的if 虚拟条件句被省去了。 在that would otherwise be uneconomical 这个定语从句中,that 指代services ,因此这个定语从句相当于一个虚拟主句:“The services would be uneconomical.”既然有了虚拟主句,那么if 虚拟条件从句在哪里?这就涉及该句型的第二个特点。 特点二:定语从句中出现的otherwise 是针对主句所述情形进行的相反假设,相当于虚拟条件从句“if it were not for …”。 例1中的主句they support the services 可以写成虚拟条件从句if it were not for their support ,或者写成if they didn’t support the services ,这也就是otherwise 所表达的含义。将这个虚拟条件从句与上面的虚拟主句结合起来,就构成这样一个完整的虚拟句:“The services would be uneconomical if it were not for their support.”所以,例1的句子相当于下面的两句话。 在此类定语从句中,关系代词that 可以充当定语从句的主语或非主语(如宾语、表语),otherwise 所表达的虚拟可以是对现在虚拟,也可以是对过去虚拟。下面我们来具体分析。 That 充当定语从句的主语 在关系代词t h a t 充当主语的定语从句中,如果otherwise 表达的虚拟是对现在虚拟,otherwise 就相当于虚拟条件从句“if it were not for …”,此时that 定语从句的结构为“that would otherwise +动词原形”。请看下面的例句。 1. They support the services that would otherwise be uneconomical. 他们对这些服务提供了极大的支持,要不然的话,这些服务将会花费不菲。 下面就利用这个例句来向大家揭示otherwise 用于that 定语从句时的用法特点。 特点一:定语从句相当于一个虚拟主句,常用到 New Oriental English . 13

like 的用法

“like”前与后-like的用法 like 表示“喜欢”,我们在使用时要重点注意它的前前后后。 I.like前 like和其它行为动词一样,在肯定句中,主语是第一人称、第二人称以及第三人称复数时谓语动词一般现在时用原形,但第三人称单数时要加词尾-s,如:Many people like science. 很多人喜欢科学。 My teacher likes reading books. 我的老师喜欢读书。 但变为疑问句和否定句时要注意: 1. 主语是第一人称(单数和复数)I、we、第二人称you以及第三人称复数they、Li Ping and Mary、the desks等,变为疑问句和否定句时要借助助动词do,谓 语动词不变。如: I like table tennis very much. → Do you like table tennis very much. They like playing basketball. → They don’t like playing basketball. 2. 主语是第三人称单数时,变为疑问句和否定句时要借助助动词does,谓语动 词改为原形。如: Mary l ikes pizza. → Mary doesn’t like pizza. He likes to play the piano. → Does he like to play the piano?
