because,since,for,as的区别.(分别举一个例子)
for ,because,as,since这四个词作为连词,都有"因为"的意思,但它们在用法上有区别:
because 是从属连词,接表示直接原因的从句,一般放在主句的后面,也可放在主句前面,它表示的语气最强,在回答why的问句时,必须用because.
例如:The swimming pool won't be open today because they're making repairs.
游泳池今天不开放,因为他们在修理.
Why did you move to France?
你们为什么搬到法国?
Because my father found work in Paris.
因为我父亲在巴黎找到了工作.
注意:在英语中用了because后,不可再用so.
as 是从属连词,说明一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句通常放在句首,有时也可放在句末.
例如:As it is raining,you\'d better take a taxi.
天下雨了,你最好乘出租车.
since 意为"既然",表示对方已知的无需加以说明的原因或事实,语气比because弱,但是比as 强.
例如:Since we have no money,we can't buy that vase.
既然我们没钱,我们就不能买那花瓶.
Since everybody is here,let's begin our party.
既然大家都到了,那就开始我们的聚会吧!
for 是并列连词,用来附带解释说明前一分句的原因或理由,for引导的并列句,一般放在所要说明的句子的后面.
例如:I went to see him,for I had something to tell him.
我去见他,因为我有事要告诉他.
