原因状语从句
（时间：60分钟，满分：80分）
原因状语从句
原因状语从句通常由because, since, as引导。
一、 because
1. because引导的从句表示直接原因，语气最强。because引导的原因状语从句常位于主句之后，但也可放在主句之前，并用逗号隔开。
I am tired because I didn’t sleep well last night.
Because I didn’t finish my homework, I was punished.
2.回答由why提出的问题，只能用because而不能用since，as。
—Why is Serina crying —Because her father had an accident.
3.because不能与并列连词so同时在句中使用。
She was late for school because she missed the bus.
= She missed the bus, so she was late for school.
4. because和because of 有明显的区别。because后面要跟从句，而because of 后跟名词、代词或动名词等。
He is late for school because it rains heavily.
= He is late for school because of the heavy rain.
二、 since / as
1．since引导原因状语从句时，表示显然的或已为人所知的理由，常译为“因为”“既然”，语气比because稍弱，多置于句首，较正式。
Since time is up, let’s have a break.
2．as表示附带说明的“双方已知的原因”，含义与since相同，但语气更弱，没有since正式。
As no classmates were there, I got back soon.
【特别提醒】
since conj./prep意为“自从...起”，引导时间状语时，主句用现完；
as的其他意思：conj. 当......时，随着；因为；正如; prep. 作为。
三、for
for作为并列连词，也有“因为”之意，它用于引导原因状语从句时不位于句首，引导
分句并不说明前句行为发生的直接原因，只是对前面的内容加以说明、解释或推断。
There must be no one in the house for the door is closed.（推断）
