因为 (because), meet 所以 (so, therefore)
Structure
因为 + reason + 所以 + result
Since [something] happened, so [something] happened.or Because of cause, therefore there is a result.
因为 pretty much means the same as "because" in English and is followed by a explanation. Coupled with 所以, it allows you to explain both the reason (cause) and the result.
Examples
因为这个 苹果 很 好吃，所以我 想 再 吃一 个。 [Because] This apple was delicious, so I’m going to have another.
因为下雨 了，所以他们 没 去 踢足球。Because it was raining, they didn’t play soccer.
Because…
因为 and 所以 can each be used alone in a sentence.
因为 can be used on its own if one wants to emphasize more on cause than on effect. Its place can vary in the sentence based on where you want to put your cause.
Example
我们 两 想 学 汉语，因为我们 明年 要 去中国。We both want to learn Chinese because we’re going to China next year.
so…therefore
所以 on its own is used to explain results and means “so, therefore”.
It is often used in a sentence where an “因为” is implied, and since there’s a cause, there’s a result.
Structure
Cause +所以+ result
Examples
你 快乐，所以我 也 快乐。You’re happy so I’m happy.
天气 很 冷，所以你 要 多 穿 一 件 衣服。 Today’s really cold so you should wear a lot of clothes.
