because的语气特别强烈,用来引导直接的、具体的和明确的原因,用来回答以“why”开头的特殊疑问句,一般放在主句之后,because引导的从句放在前面时应在主句和从句之间加一个逗号。例如:
(1)A: Why are you late again? 你为什么又迟到了?
B: Because the traffic is bad. 因为交通堵塞。
(2)He didn’t come with me because he had a lot of things to do. (= Because he had a lot of things to do, he didn’t come with me.) 他没有和我一起来,因为他有很多事情要做。4．for表示所说的理由是一种补充说明,因此,for引导的从句可以放在括号里,而且for引导的从句一般不放在句子的开头。例如:
I decided to stop and have lunch, for I was feeling quite hungry.
