because和because of的区别
becauseof等几个短语表示原因的区别
because of, due to , on account of , owing to , thanks to , as a resul...because of, due to , on account of , owing to , thanks to , as a result of ,等都可以用来表示原因，但其用法却各有不同。
一、because of意为“因为，由于”，普通用语，比其他短语更口语化；构成的短语在句子中通常作状语，一般不作表语用；若引导表语，主语通常应为代词。
后面可接名词、代词、分词或what引导的名词性从句等。
Sampras is likely to miss the US Open because of his back injury.桑普拉斯因为背部有伤可能缺席美国公开赛。
（置于句后作状语）Because of my bad leg ,I couldn’t walk so fast as the others.由于我的腿坏了，我不能像其他人走得那么快。
（置于句首做状语，但用逗号与其他部分分开）Because of his wife’s being there, I said nothing about it.因为他妻子在场，我对此事只字未提。
(接-ing分词短语)He realized that she was crying because of what he had said.他意识到她在哭是因为他说的那些话。
(接what从句)It is all because of what you said.那完全是因为你说的话。
(接what从句)二、due to“由于，因…造成”，按照传统语法：due to主要引导表语，但是在现代英语中，due to也可用来引导状语（此时不用于句首），也可作定语。
His illness is due to bad food.他生病是由于吃了不好的食物。

because的用法归纳_用法辨析 英语语法.doc
because的用法归纳_用法辨析1. 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 likehim. 是因为他诚实我们才喜欢他。
5. notbecause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：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 speakill of you. 你不要因为有人说你坏话而生气。
He was not readyto 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。
6. 表示的原因是因为这一意义时，一般要用下面这样的句型。
如：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。
7. 汉语习惯上说因为所以，但在英语里却不能将so与because 连用。
