Not…because句型及because的

其它用法

一、because 常见用法

1. because 表示的原因是必然的因果关系,语气较强,通常放在主句之后,若需强调则放在主句之前。

2. 通常用来回答why提出的问题。如:

A:Why can’t you do it now?你为什么不现在就做呢?

B:Because I’m too busy.因为我太忙。

3. 可引导从句作表语。如:

It is because he is foolish. 那是

因为他太蠢了。

4. 可用于强调句。如:

It is because he is honest that we like him. 是因为他诚实我们才喜欢他。

二. not…because…这一结构中的

not 有时否定主句,有时否定从句,一般要根据句子的意思作出正确或合乎逻

辑的理解。若not否定主句,最好在because之前用逗号,否则会引起歧义,如下句在没有特定上下文时就有两种解释。如:

1)They did not come to the hospital because they wanted to see me.

第一眼看上去,你肯定会说:"这还不容易。他们没有到医院来,因为他们想

来看我。"仔细想想,为什么他们想来看我,却又不到医院来呢?如果说我不是

住在医院里,那为什么要说"come to "?应该说"go to"才对。是不是逻辑上有点自相矛盾?其实此句是一种特殊结构,其中not 的是用以否定because所引导

的状语从句。我们把not搬回它的老家,放在because之前,就可以正确的翻译这个句子了,应该是"他们到医院来,不是因为要看我(而是为了其他原因)。

2)The motor did not stop running because the fuel was finished. 摩托车停止转动,不是因为燃料用完。(而是因为其它毛病)

3)These rings are not valued because they are set with precious stones. 这些指环的价值并不在于它们镶有宝石。

但我们不能把所有的

not ….because句子都看作是特殊结构,例如:

4)He did not come to the studio this morning because he was sick. 今早他没有来片场,因为他病了。这里的not是说明come,不是修饰because。如译为:"他今早没来片场并不是因为他生病(而是为了其他的原因)"。显而易见,这样的理解和翻译是错误而且不通的。

怎么知道它是普通结构还是特殊结构呢?

判断的依据不外乎下列几种:

(一)逻辑推理;

(二)文章的内容和上下文;

(三)语感;

(四)词典。

在这四种辨别句型的依据中,最为常用的是第一种,即"逻辑推理"。如果把普通结构作为特殊结构去处理,翻译出来的译文是文理不通或毫无意义的,反之亦然。

但是,在个别场合下,依靠逻辑推理是不能解决问题的,请看下例:

5)I did not write that letter because of what you told me. 此句既可看作普通结构,理解为:

6)I refrained from writing that letter because of what you told me. 由于你跟我说了,所以我没有写那封信。

也可以把这一句看作特殊结构,理解为:

7)It was not because of what you told me that I wrote that letter. 并不是因为你跟我说了,我才写那封信的

8)I didn’t go because I was afraid.

(1) 我没有去是因为怕。

(2) 我不是因为怕才去。

不过若because之前有just修饰,一般认为not 是否定从句而不是主句。如:

You shouldn’t get angry just because some people speak ill of you. 你不要因为有人说你坏话而生气。He was not ready to believe something just because Aristotle said so. 他并不只是因为亚里士多德

说过如何如何,就轻易相信它。

三、用于复合介词because of,其后可接名词、代词、动名词、what 从句等。如:

He is here because of you (that). 他为你(那事)而来这里。

We said nothing about it, because of his wife’s being there. 因为他妻子在那儿,我们对此只字未提。

He left the company because of what the boss said at the meeting. 他离开了这家公司,是因为老板在会上讲的话。

但是,because of后不能直接跟that 从句或者是没有引导词的从句。如:

由于我的病我不能干这工作。

正:I can’t do the work because of my illness.

正:I can’t do the work because

I’m ill.

四、否定转移

高考英语中最常见的否定是用否定副词not来表示。英语的否定可分为一般否定和特指否定。一般否定通过not否定句子的谓语来否定全句,特指否定的

not否定句子的特定部分。但有时,对句子某一部分的否定不通过直接否定那一部分,而是通过否定句子的谓语来实现。这种变特指否定为一般否定的现象叫做1)(transferred negative)。常见的否定转移有下列几种情况:

一)当think,suppose,believe,imagine,fancy,guess,should say 等表示主观意见和猜想的动词在句中作谓语时,按习惯其宾语从句的否定通常转移到主句。例如:

1.There'd be men who I didn't think would want to be fooling around with him. 我认为有人不愿和他鬼混。

2.We don't suppose he will pay. 我们认为他不会付钱。

二)在seem,feel,taste,sound,appear作联系动词的句子中,特别是seem,按习惯以它的否定来代替其他部分的否定。例如:

1.English doesn't seem easy to learn. 英语好像不容易学。

2.It didn't seem during those years that there could be anyone else who might share my own peculiar tastes. 在那些年月里,似乎没有人会有我这样的特殊情趣。

类似的情况还有半助动词happen。例如:

He didn't happen to be at home. 他碰巧不在家。

三)以because引导的从句或because of引导的介词短语在句中作

原因状语时,其否定常常转移。见前,二. not…because…这一结构

1.I don't teach because teaching is easy for me., and nor do I teach because I think I know answers, or I have knowledge I feel compelled to share with others. (=I teach not because…

neither becaus e…) 我当教师,并不是因为我觉得教书轻松……也不是因为我认为自己能够解答各种问题,或者因为我有满腹学问,觉得非与别人分享不可。

2.I didn't go there because of his request. (=I went there not because of his request.) 我不是因

为他的要求而去的。

在有些情况下,否定显然是在主句,而不在从句,并未转移。例如:

I couldn't concentrate because I was so hungry, because I hadn't had my breakfast. 我无法集中精力,因为我很饿,因为我没有吃早饭。

有时,特指否定和一般否定界线不明,因而产生歧义。例如:

I didn't go because I was afraid. 特指否定:我去了,但不是因为我害怕。一般否定:我没有去,因为我害怕。

当句子是一般否定时,为避免歧义,在口头表达时,需在because前稍作停顿。在书面表达时,可在because前用逗号将从句和主句分开。例如:

He didn't go to school, because he was ill. 他没去上学,因为他病了。

五、表示“…的原因是因为…”这一意义时,一般要用的句型

1、The reason why he can’t come is that he is tired. 他不能来是因为

他累了。

在这一结构中尽管不少人认为可将that改用because, 但也有不少人反对这一用法,学生宜慎用。

2、汉语习惯上说“因为…所以…”,但在英语里却不能将so与because 连用。如:

因为下雨,所以我们呆在家里。

正:Because it was raining, we stayed at home.

正:It was raining, so we stayed at home.

误:Because it was raining, so we stayed at home.

3、用于because of, 意为“因为”,用法注意:

(1) 是复合介词,其后可接名词、代词、动名词以及由关系代词型的what 所引导的从句等。如:

He couldn’t come because of illness. 他因病不能来。

I said nothing about it, because of his wife’sbeing there. 因为他妻子在那儿,我对此事只字未提。

He knew shewas

crying because of what he had said. 他知道她哭是因为他说的话。

注意:

because of不能直接引导从句或后接that引导的从句。如:

他不能来是因为他病了。

正:He can’t come because he is ill.

正:He can’t come because of his illness.

误:He can’t come because of he is ill.

误:He can’t come because of that he is ill.

(2) because of 一般引导状语,不引导表语(引导表语时可用dueto)。如:正:His absence is due to the rain. 他因雨未来。

误:His absence is because of

the rain.

但是若主语是代词(不是名词),because of 引出的短语则可用作表语。如:

It is just because of money. 那

只是因为钱的原因。

4、关于because,since, as, for 的用法区别

(1) . because 可用来回答why提出的问题;可以引导表语从句;可用于强调句等,而其余三者则不行。

(2) because 表示的是必然的因果

关系,语气最强,通常放在主句之后,若需强调则放在主句之前;since, as所表示的原因是人们已知的,是对已知事实提供理由,而不表示直接原因。它们引导的从句通常放在主句之前,有时也放在主句之后。如:

As he wasn’t ready in time, wewent without him.因他未及时准备好,我们没等他就先走了。

Since we have no money, it’s no good thinking about a holiday. 既然我们没有钱,考虑度假有什么用。

至于for, 它是并列连词(其余三者为从属连词),它有时可表示因果关系(通常要放在主句之后,且可与because 换用);有时不表示因果关系,而是对前面分句内容的解释或推断(也

要放在主句之后,但不能与because 换用)。试比较:

①The ground is wet, for

(=because) it rained last night. 地面是湿的,因为昨晚下过雨。

②It must have rained last night, for the ground is wetthis morning. 昨晚一定下过雨,你看今天早上地面是湿的。

有关as作连词的用法

有关as作连词的用法 一.as引导状语从句 as作为连词可以引导状语从句,表示时间、原因、方式、让步等。 1. 引导时间状语从句,意思是“当``````的时候”,同when/while,更强调“一边``````一边``````”。表“随着``````”的意思时同with,但with是介词,不可以跟从句。 eg: I saw him as he was getting off the bus. He often listens to the music as he is doing his homework. As time goes by, his illness is getting worse. 2. 引导原因状语从句,同since。 eg: We had better hurry as it is getting dark. As she has no car, she can’t get there easily. 有关as作连词的用法 一.二.as引导定语从句 1. as引导限制性定语从句。 as作为关系代词可以引导限制性定语从句,通常与the same或such连用,构成the same ``````as和such``````as句型。 eg: I have never heard such stories as he tells. This is the same dictionary as I lost. 有关as作连词的用法 要用倒装结构。可以把从句中表语、状语甚至谓语动词置于句首,如果是带有冠词的可数名词单数作表语,置于句首时应省去冠词。 eg: Young as he is, he knows a lot about history. Much as I like you, I will not marry you. Try as she might, Mary couldn’t get the door open. Boy as he is, he is very shy. (boy前省略冠词a) 4. 引导方式状语从句,表示方式。意思是“像,按照,如同”。 eg: Do it as I do it. You should finish your task as you are told to. Leave it as it is. 有关as作连词的用法 2. as引导非限制性定语从句。 as与which一样都可以引导非限制性定语从句,但是as引导的从句可以放在主句之前、主句之后,甚至还可以分割主句;而which引导的非限制性定语从句只能放在主句之后。另外as还有“正如、就像”之意。 eg: As is mentioned above, the number of the students in senior high schools is increasing. He was admitted to college, which made his parents very happy. John, as you know, is a writer. 动词不定式 动词不定式是非谓语动词的一种,它没有人称和数的变化,在句子中不能独立作谓语,但它仍保持动词的特点,既可以有自己的宾语和状语。

Origin 使用问题

Origin 使用问题集锦 1. 请教怎样反读出 origin 曲线上全部数据点? 如,我用 10个数据点画出了一条 origin 曲线,并存为 project的.OPJ 格式。但,现在我想利用 OPJ 文件从这条曲线上均匀的取出 100个数据点的数值,该如何做?注:要一切都使用 origin 软件完成,不用其他曲线识别软件。 Answer: ORIGIN 中,在分析菜单(或统计菜单)中有插值命令,打开设置对话框,输入数据的起点和终点以及插值点的个数,OK!生成新的插值曲线和对应的数据表格。 2. 如何用origin 做出附件中的图: 其中标注的三角形、方块是怎么整上去的? Answer: 选中左侧竖工具条中的 draw tool(显示是几个点,第七个工具),移动到你要标注的位置双击,就产生了一个点,依次标注完方块。再标注三角的第一个点,标注完后改成三角,以后标注的就都是三角了。改动点的类型的方法和正常画曲线方式一样。 3. 如何用origin 做出附件图中的坐标轴(带刻度)?

Answer: 你把刻度改成那样不就行了。 8.0 的具体方法是双击坐标轴,title & format --> 选左边那个 bottom,然后在右边把 axis 改为 at position=。同理,然后选左边的 left,把axis也改为 at position=。 4. origin能否读取导入曲线的坐标? 一张 bmp 格式的图片,图片内容是坐标系和拟合曲线,但是不知道用什么软件绘制的。请问能否将该图片导入 origin,读出曲线上任意一点的数据? Answer: (1). 1.ORIGIN 有一个图形数字化插件可完成该任务。 2.有许多专门的图形数字化软件也可完成此任务。个人感觉专门的比插件也用、便捷。推荐 WINDIG25 (2). origin下的数字化插件是digitizer,下载地 址:https://www.360docs.net/doc/9117488636.html,/fileexchange/details.aspx?fid=8拖入origin即可,但使用不是很方便。比较方便的是un-scan-it。 5. 如何在origin7.5 中标峰值? 用origin7.5 作的XRD图,怎样直接在峰上标数据? Answer: Tools/Pick peaks 设置一下点击 Find Peaks 就 OK了。Positive和Negative 是标正负峰值的意思,其他数值改变一下就知道干吗用的了。 6. 关于origin 拟合曲线延长的问题? 我想把拟合之后的直线向前或向后延长一段距离与坐标轴相交。但是不知道该怎么弄。是不是要改那个范围的最大值和最小值啊?可是怎么改?

as作连词的用法

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)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。 几个关于as...as的常见句型: (1)as...as possible Please answer my question as soon as possible.请尽快回答我的问题。 (2)as...as usual/before She looks as pretty as before.她看起来和以前一样漂亮。 (3)as long as... (引导条件状语从句) It took us as long as three years to carry out the plan.我们花了长达三年的时间才完成这项计划。 (4)as far as He walked as far as the railway station yesterday evening.昨天傍晚,他一直散步到火车站。 (5)as well as She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。 一些带有as...as结构的常见短语归纳: as busy as a bee像蜜蜂一样忙碌 as easy as ABC像ABC一样容易 as deep as a well像井一样深 as light as a feather像羽毛一样轻 as soft as butter像黄油一样软 as rich as a Jew像犹太人一样富裕 2. as用作连词引导时间状语从句 as与when,while都是引导时间状语从句的从属连词,含义都是"当……的时候"。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,

because,since,as,for的用法区别

because、since、as、for的用法区别 because、since、as、for这几个词都是表示“原因”的连词,语气由强至弱依次为:because→since→as→for。其中because、since和as均为从属连词,引导原因状语从句;而for是并列连词,引导并列句。 ?because because表示直接原因,它所指的原因通常是听话人所不知道的,其语气最强。常用来回答why的提问,一般放在主句之后,也可以单独存在例如: (1)Istayed at home because it rained. 因为下雨,我呆在家里。 (2)B ecause Lingling was ill, she didn’t come to school. 玲玲因为生病,没有上学。 (3)—Why is she absent? 她为什么缺席? —Because she is sick. 因为她病了。 (4)此外,在强调句型中只能用because。例如, It was because I missed the early bus that I was late for school. 我上学迟到是因为我错过了早班车。 ?since since侧重主句,从句表示显然的或已为人所知的理由,常译为“因为、既然”,语气比because稍弱,通常置于句首,表示一种含有勉强语气的原因。例如: (1)Si nce he asks you, you’ll tell him why. 他既然问你了,那就告诉他为什么吧。 (2)Si nce everyone is here, let’s start. 既然大家都到齐了,我们就是出发吧。 (3)Since I understood very little Japanese, I c ouldn’t follow the conversation. 我日语懂得不多,因而听不懂对话。 ?as as是常用词,它表示的“原因”是双方已知的事实或显而易见的原因,由于理由不是很重要,含义与since相同,但语气更弱,没有since正式,常译为“由于,鉴于”。从句说明原因,主句说明结果,主从并重。例如:

because, since, as与for用法辨析

because, since, as与for用法辨析 1. because的用法 because语气最强,表示直接原因,可用于回答 why 提出的问题、引导表语从句、用于强调句等,而其余三者均不行。如: A:Why didn’t she come? 她为什么没来? B:Because she was very busy. 因为她很忙。 It is because he is clever that I like him. 是因为他聪明我才喜欢他。 2. since与as 两者所表示的原因都是人们已知的,即对已知事实提供理由,而不是表示直接原因。since 比 as 语气稍强,且比 as 略为正式,它们引导的从句通常放在主句之前,有时也放在主句之后。如: As you weren’t there, I left a message. 由于你不在那儿,我留了个口信。 Since you’ve been here a w hile, you might as well stay. 既然你已经来了一段时间,就不妨继续待下去。 另外,since 可用于省略句,而其他三者不行。如: Since so, I have nothing to say. 既然如此,我无话可说。 3. for的用法

for是并列连词,而其余三者为从属连词。for有时可表示因果关系(通常要放在主句之后,且可与 because 换用);有时不表示因果关系,而是对前面分句内容的解释或推断(也要放在主句之后,但不能与because 换用)。比较: The ground is wet,for (=because) it rained last night. 地面是湿的,因为昨晚下过雨。 It must have rained last night,for the ground is wet this morning. 昨晚一定下过雨,你看今天早上地面是湿的。 (此句不能用 because 代 for) 英语微信群是目前学习英语最有效的方法,群里都是说英语,没有半个中文,而且规则非常严格,是一个超级不错的英语学习环境,群里有好多英语超好的超牛逼的人,还有鬼佬和外国美眉。其实坦白说,如果自己一个人学习英语太孤独,太寂寞,没有办法坚持,好几次都会半途而废。只要你加入到那个群里以后,自己就会每天都能在群里坚持学,坚持不停地说和练,由于是付费群,群里的成员学习氛围非常强,每天的训练度都非常猛,本来很懒惰的你一下子就被感染了,不由自主地被带动起来参与操练,不好意思偷懒,别人的刻苦学习精神会不知不觉影响你,EYC英语微信群(群主vx 601332975)可以彻底治好你的拖延症,里面学员都非常友好,总是给你不断的帮助和鼓励,让你学英语的路上重新燃起了斗志,因为每天都在运用,你的英语口语就能得到了迅猛的提升,现在可以随便给一个话题,都能用英文滔滔不绝的发表5分钟以上对这个话题的看法和观点,想提高英语口语的可以加入进来,It really works very well.

as 用法详解

as 用法详解 1.用作连词,表示让步 (意为:虽然,尽管),要用于倒装句,且倒装后位于句首的名词通常不用冠词 (等于though, 但语气稍弱)。如: Child as[though]he was, he did quite well. 他虽是个孩子,但已干得很不错。 2.用作关系代词,主要用法有二。如: (1)用在such, same, as等之后,引导限制性定语从句。如: This is thesame watch as I lost. 这块表跟我丢失的那块一样。 Such men as (=Those men who) heard of him praised him. 听说过他的人都赞扬他。 (2)单独用作关系代词,引导非限制性定语从句,可放在主句之前 (常译为:正如)或之后 (常译为:这一点),且主从句之间一般要用逗号隔开。如: He was absent, as is often the case. 他缺席了,这是常有的事。 As was expected, he succeeded at last. 正如我们所料,他终于成功了。 3.用来表示目的,下面两种句子结构都可以。如: 仔细写以便把每句话都写清楚。 正:Write carefully so as to make every sentence clear. 正:Write so carefully as to make every sentence clear. 4.在正式文体 (尤其是文学体裁)中,as后可用倒装语序表示“…也一样”这类意思 (现代英语通常so表示这一用法)。如: He travelled agreat deal, as did most of his friends. 他去过许多地方旅游,他的多数朋友也是一样。 He plays the piano, as does his mother. 他会弹钢琴,他母亲也会。 注:用作连词,表示原因 (参见because),表示时间 (参见when)。 5.用于 as if as though, 意为“仿佛”、“似乎”。两者一般可通用 (但注意不能说 as although)。用法上注意几点:

连词ant but so because用法

并列连词and,but,so,because用法 基本用法 1.and的用法 and用来连接两个并列的成分,表示添加、补充、引申。 She sings and dances very well. 她唱歌跳舞都很好。 My tall friend is handsome, intelligent and strong. 我的那个高个子朋友长得英俊,头脑聪明,身体又强壮。 2.but的用法 并列连词but意为“但是”,表示转折关系,所连接的成分意思相反或相对。例如: (1)Our school is small but beautiful.我们学校虽然小但很漂亮。(连接两个形容词,意思相对) (2)The car is very old but it runs very fast.虽然小汽车旧了,但跑得很快。 3.so的用法 并列连词so表示“因此、所以”之意,常用来连接两个简单句,这两个简单句有意思上的因果关系。例如: (1)The rain began to fall,so we went home.天开始下雨了,所以我们就回家了。 (2)Everyone in the town knew him ,so we had no trouble finding his house.镇上谁都认识他,因此他们毫不费力就找到了他的家。 so和从属连词because(因为)不能一起连用。也就是说,使用了并列连词)。

就不用because(从属连词);使用了because,就不用so。例如: He was ill,so he didn't go to school 他病了,所以没去上学。 He didn't go to school because he was ill.他没去上学,因为他病了。 1.表示原因,语气较强,可用来回答why 提出的问题。如: A:Why do you love her? 你为什么爱她? B:Because she is kind. 因为她很善良。 2.汉语说“因为……所以……”,但英语却不能用because…so…这样的结构。because不能和so连用,一山不能容二虎如: 正:Because he is ill,he can't come.因为他生病了,所以来不了。 正:He is ill,so he can't come.他生病了,所以来不了。 误:Because he is ill,so he can't come. 相关练习题 一、用and, but, so,because填空填空。 She is tall ________ thin.

Origin 使用问题集锦

1. 请教怎样反读出origin曲线上全部数据点? 如,我用10个数据点画出了一条origin曲线,并存为project的.OPJ格式。 但,现在我想利用OPJ文件从这条曲线上均匀的取出100个数据点的数值,该如何做?注:要一切都使用origin软件完成,不用其他曲线识别软件。 https://www.360docs.net/doc/9117488636.html,/bbs/viewthread.php?tid=1390313 Answer: ORIGIN中,在分析菜单(或统计菜单)中有插值命令,打开设置对话框,输入数据的起点和终点以及插值点的个数,OK!生成新的插值曲线和对应的数据表格。 2. origin中非线性拟合中logistic模型的疑问? origin 中非线性拟合中的logistic模型为 y = A2 + (A1-A2)/(1 + (x/x0)^p) 其初始参数设置为 sort(x_y_curve); //smooth(x_y_curve, 2); x0 = xaty50( x_y_curve ); p = 3.0; if( yatxmin( x_y_curve ) > yatxmax( x_y_curve ) ) { A1 = max( y_data ); A2 = min( y_data ); } else { A1 = min( y_data ); A2 = max( y_data ); } 而据我看到的logistic的模型都是(自己origin中自定义的) y =A1/(1+(A1/A2-1)*exp(-k*x)) 也就是说origin 中的logistic有4个数值需要确定,而自定义的有3个数值 从结果来看,没有太大区别,但为什么函数不一样呢? 不是学数学,高人能否详细说明下。 https://www.360docs.net/doc/9117488636.html,/bbs/viewthread.php?tid=1391522 Answer: 你可以看一下这个文档,里面有数种不同形式的logistic 模型: https://www.360docs.net/doc/9117488636.html,/web/packages/drc/drc.pdf 当然,这是一个R (https://www.360docs.net/doc/9117488636.html,) 包的文档,但不妨碍你看其中的公式。 R 是开源的啊,以GPL 发布,可以从https://www.360docs.net/doc/9117488636.html,上了解更多。

as作连词的用法

I read the letter as I walked along the river. As(when he was) a small boy, he began to learn English As (While) the teacher is explaining the text,the students are taking notes. 二、原因状语从句 as引导原因状语从句,意为由于……鉴于……语气比because、since弱,表示明显的或已为对方所熟悉的原因,一般放在主句之前。如果放在主句之后,则表示对主句附加说明。如: As it is raining hard,we won’t go out. We a11 1ike her as she is kind. As he was in hurry, he left his bag at home. 三、让步状语从句 as引导让步状语从句,意为虽然,尽管,通常从句要用倒装,即从句的表语/状语放在as之前。如果从句中表语是单数名词,那么名词前不加冠词。如:Young as he is,he knows a lot.(young作表语) Hard as he works,he has made little progress.(hard作状语) Child as he is,he knows a lot.(child前不加冠词)
