because，since，as和for的区别

because，since，as和for的区别~

becaue since as和for表达原因时的区分

三者均可用来表示原因，区别如下：
1.关于 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，而其余两者均不行：
“Why didn’t he come?” “Because he was ill.” “他为什么没来?”“因为他病了。”
My stomach hurts because I have eaten too many apples. 我肚子痛，因为苹果吃得太多。
That’s because you can’t appreciate music. 这是因为你不能欣赏音乐。
It is because he is honest that I like him. 是因为他诚实我才喜欢他。
2. 关于 since 与 as：
1）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：
As you weren’t there, I left a message. 由于你不在那儿，我留了个口信。
Since you are wrong, you should apologize. 你既然错了，就应该道歉。
2） since 可用于省略句，而其他两者不行：
Since so, I have nothing to say. 既然如此，我无话可说。

since, as because,for都可表示原因，它们的区别是：

1. Becasue：当原因作为句子或陈述最重要的一部分时，我们使用because.
Because通常出现在句首部分。
Because is used when the reason is the most important part of the sentence or utterance. The because clause usually comes at the end:
e.g. I went to Spain last summer because I wanted the guarantee of sunshine on every day of my holiday.

2. As和since：当原因是众所周知时，我们使用as和since，因此，这样的原因一般不那么重要。
as或since从句一般置于句首。
As and since are used when the reason is already well known and is therefore usually less important. The as or since clause is usually placed at the beginning of the sentence:
e.g. As the performance had already started, we went up to the balcony and occupied some empty seats there.
e.g. Since John had already eaten, I made do with a sandwich.

3. For：For意味着原因是事后给出的。
For从来都不会置于句首，带有书面英语而非口语的色彩。
For suggests that the reason is given as an afterthought. It is never placed at the beginning of the sentence and is more characteristic of written, rather than spoken English:
e.g. I decided to stop the work I was doing - for it was very late and I wanted to go to bed.
