1. because是从属连词，引导原因状语从句，表示直接的原因或理由，常用于why引导的疑问句。如：
Why do you like dogs?
你为什么喜欢狗？
Because they are friendly.
因为他们很友好。
2. because引导的原因状语从句可以放在主句前或主句后，但一般放在主句后。如：
I won’t go there because I want to do my homework.
我不会去那里，因为我想做家庭作业。
I like winter because I like to skate.
我喜欢冬季，因为我喜欢滑冰。
注意：（1）because 习惯上不与so 连用。在汉语中我们习惯上说“因为…所以…”但在英语中却不能将二者连用。如：
Because it was raining,we stayed at home.
因为下雨，所以我们待在家里。
或It was raining ,so we stayed at home.
错误说法：Because it was raining ,so we stayed at home.
（2）because引导的原因状语从句有时可以与because of互换，但because of后面接名词或短语。如：
He can’t come because he is ill.=He can’t come because of his illness.
因为生病，所以他没来。
Because of the law in Ireland, we had to work out a way of getting her over to Britain.
由于爱尔兰的法律所限，我们不得不想办法把她弄到英国去。
It is mainly because of my fault.
这主要是由于我的过错。
