Sentence pattern · Band 2

因为……所以……: because, so

因为 A,所以 B

English feels awkward saying because and so in one breath, so it picks one. Mandarin has no such manners: 因为 states the cause, 所以 announces the result, and a proper sentence often wears both, like a matching pair of socks. Cause first, result second, and the listener glides down the sentence like a slide.
