because引导的原因状语从句
原因状语从句是指在复合句中表示主句动作发生原因的句子。如：
I did not go to school yesterday because I was ill.
我昨天没去上学，因为我生病了。
Because it was raining, we had to stay at home.
因为下雨，我们只好待在家里。
because意思是“因为”，表示动作发生的直接原因，语气很强，常用来回答why引导的疑问句。如：
—Why didn't he go with us today 他为什么今天没跟我们一起去？
—Because he was too tired. 因为他太累了。
汉语里我们习惯说“因为……所以……”，但使用英语时不能将because与so连用。如：
Because my bike was broken, I went to school by bus yesterday. (√)
Because my bike was broken, so I went to school by bus yesterday. (×)
since和as引导的原因状语从句
我们也可以用since和as引导原因状语从句。如：
Since you are free, you'd better tidy your bedroom.
既然你有空，你最好把卧室整理一下。
As you were not there, I left a message.
因为你不在那里，所以我留了个信儿。
注意：和because相比，since和as的语气稍弱。
since意思是“既然，由于；因为”，表示已知的、显然的理由，较正式，多位于句首。如：
Since it is late, I shall go home right now.
（由于）时间不早了，我得马上回家。
as和since的用法大体相同，表示附带说明的“双方已知的原因”。如：
As it is raining, you'd better take a taxi.
既然在下雨，你最好乘出租车。
