除了下面A2,A3中所示各种类型外,这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥;用because引导结果/原因从句较为稳妥(参见B)。
A 原因从句
1 由as/because/since 引导的原因从句:
We camped there as/because/since it was too dark to go on.
我们在那里露宿是因为天太黑,不能再继续往前走了。
As/Because/Since it was too dark to go on,we camped there.
因为天太黑不能再继续往前走,我们就在那儿露宿了。
2 in view of the fact that可用as/since/seeing that来表示,但不能用because:
As/Since/Seeing that you are here,you may as well give me a hand.
既然你在这儿,你就帮我个忙吧。
As/Since/Seeing that Tom knows French,hed better do the talking.
既然汤姆懂法语,最好让他来谈。
3 在as/since/seeing that意指以前共知的或共知的陈述时,可用if来代替:
As/Since/Seeing that/If you dont like Bill,why did you invite him?
既然/如果你不喜欢比尔,你为什么邀请了他?
注意:if so的用法:
I hope Bill wont come.
