because与because of的用法比较_用法辨析

一、从词性上看

because 是连词,其后接句子;because of 是复合介词,其后接名词、代词、动名词、what 从句等。如:

I didnt buy it because it was too expensive. 我没有买是因为它太贵了。

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

He lost his job because of his age. 由于年龄关系他失去了工作。

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

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

注意:because of 之后可接what 从句,但不能接that 从句或没有引导词的句子。如:

他因病未来。

误:He didnt come because of he was ill.

误:He didnt come because of that he was ill.

正:He didnt come because he was ill.

正:He didnt come because of his illness.

比较以下同义句:

他离开了这家公司,是因为老板在会上讲的话。

正:He left the company because of what the boss said at the meeting.

正:He left the company because of the thing that the boss said at the meeting.

我不能因为有个家就停止斗争。

正:I cant stop fighting because I have a family.

正:I cant stop fighting because of having a family.

二、从用法上看

because 所引导的从句除用作原因状语外,还可用作表语。如:It is because he loves you. 那是因为他爱你。

而复合介词because of 所引导的介词短语通常用作状语而不用作表语。如:

他因雨缺席。

误:His absence was because of the rain.

正:His absence was due to the rain.

正:He was absent because of the rain.

但是有时若主语是代词(不是名词),也可以用because of 引出的短语作表语。如:

It is just because of money. 那只是因为钱的原因。

That was because of his sickness. 那是因为他生病的原因。

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.

高中英语语法---条件状语从句讲解

条件状语从句 概念定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中,条件是指某一件事情实现之后(状语从句中的动作),其它事情(主句中的动作)才能发生,通常译作“假如”。(注意:在含有条件状语从句的复合句中,表示将来时态,主句是一般将来时态,祈使句或情态动词,从句要用现在时态,[主将从现原则](主将从现,将并非指将来时,还指表示将来含义的,跟着if后的那句话是从句。) 类型 条件状语从句 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如: 1) If you ask him,he will help you. 如果你请他帮忙,他会帮你的。 2) If you fail in the exam,you will let him down. 如果你考试不及格,你会让他失望的 if引导的条件状语从句既可以将从句放前面也可以将从句放后面 (如果天下雨,我们就不玩了)If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句

另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如:If I were you,I would invite him to the party.如果我是你,我会邀请他参加聚会。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。 那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非,若不,除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨,比赛将照常进行。 2、on condition(that)...在……条件下,如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果,假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗? Supposing anything should go wrong,what would you do then?假如出了什么问题,你准备怎么对付?
