新课讲授
Giving reasons with because
Part A
What is a clause of reason
原因状语从句是指在复合句中表示主句动作发生的原因的句子
We use because to introduce clauses of reason.
1. because意为“因为”，表示动作发生的直接原因，语气很强。
e.g. I like listening to music because it makes me feel relaxed.
I like painting because I like all the different colours.
2. because可以用来回答why引导的疑问句。
e.g. ---Why doesn’t he go with us ---Because he’s too tired today.
3. 在一个英语句子中，so和because不能同时出现。
e.g. Because my bike was broken, I walked to school yesterday. (√)
Because my bike was broken, so I walked to school yesterday. (×)
4. because of也可表达直接的原因，后接名词代词或动名词。一般情况下可以和because引导的从句互换。
e.g.
1. 由于生病，他不能来。
He can’t come _________ he is ill.
= He can’t come ____________ his illness.
2. 由于大雨，他迟到了。
He was late _________ he got up late.
= He was late ____________ getting up late.

Giving reasons with since and as
Part B
Since, as and for are also used to give reasons for something.
1. since意为“因为，既然”， as意为“由于，鉴于”。相对于because而言，since和as的语气较弱。since和as的用法大体相同，表示附带说明的“双方已知的原因”。由这两个词引导的原因状语从句通常位于句首。
e.g. Since it is late, I shall go home right now.
As it is raining, you’d better take a taxi.
2. for属于并列连词，不是说明直接原因，而是对某种情况加以推断或解释，对前一分句进行附加说明。由它引导的分句通常只能置于句末，且必须用逗号与前面的分句隔开。
e.g. He must have passed this way, for here are his footprints.
There must be no one in the house, for the door is closed.
