原因状语从句
1because,since和as的区别
（1）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，而其余三者均不行：
“Whydidn’thecome?
”“Becausehewasill.”“他为什么没来?
”“因为他病了。
”
Wemuststayathomebecauseitrained.我们必须呆在家，因为下雨了。
（2）since较弱，指双方都明确的原因或众所周知的原因，泽为“既然”，侧重主句，从句表示显然的或已知的理由。
Sinceyoudon'tlikeit,I'llputitaway.既然你不喜欢，我就把它放在一边。
Sinceeverybodyishere,let’sbeginourclass.既然每个人都在，我们开始上课吧。
（3）as“由于，鉴于”，指客观事实，语气比since弱，略口语化，常与since互换使用。
Astherewasnoanswer,Iwroteagain.
鉴于没回复，我又写了一封信。
语气
位置
意义
because
最强
前或后
“因为”，表示客观因果关系
since
较强
前
“既然”，把众人所知的事实当作理由，较为正式
as
较弱
前
“由于”，把众人所知的事实当作理由，口语化
总结：
2、because习惯上不与so连用
汉语习惯上说“因为…所以…”，但英语习惯上却不能将so与because连用：
正：
Becauseitwasraining,westayedathome./Itwasraining,sowestayedathome.
误：
Becauseitwasraining,sowestayedathome.因为下雨，所以我们呆在家里。
3、becauseVSbecauseof
because后加句子，引导原因状语从句。
例如：
IdoitbecauseIlikeit.我做这件事情因为我喜欢。
becauseof后加名词，代词，动名词。
Thefootballmatchwillbeputoffbecauseofthebadweather.
因为坏天气，足球赛将会延期。
两者可以互换
Hecan'tcomebecauseheisill.
==Hecan'tcomebecauseofhisillness.他因病不能来。
Isaidnothingaboutitbecausehiswifewasthere.
==Isaidnothingaboutitbecauseofhiswife'sbeingthere
因为他妻子在那儿，我对此事只字未提。
