谁知道英语表"因为"有几个单词，分别有什么用法，每个用法后再来几个例子！ 最好是老师来解答！

我觉得主要初高中掌握这五个就可以了 1 because 2because of 3 for 4on account of 5as
because 和 because of 区别在于 because 后接句子 because of 后接短语 如果是动词的话 要用ing 形式的
I study because I want to learn.
我学习是因为我想学到知识
As you weren't there I left a message.
因为你不在那里, 我留了个信儿
The flight was postponed on account of bad weather.
因为天气恶劣， 飞行延期了。
I'm pretty angry with you for not telling me.
由于你没有告诉我, 我对你很生气

1.because “因为”引导原因状语从句
He didn't go to school today because he was ill.
2.as “由于”引导原因状语从句，语气较because 弱一些
As tomorrow is Saturday,we will go to the park.
3.for “由于，因为”，连接并列句
We'll walk there,for it's not far.

because
例；because she is my mother.
