掌握 so 和 therefore 的用法和区别

so 和 therefore 是两个非常实用的连接词。我们可以使用 so 和 therefore 来谈论某件事情的结果。 so 通常出现在句子的中间，而 therefore 则出现在一个新句子的开头。相较于 so，therefore 更加正式。

下雨了，所以我呆在家里。
It was raining, so I stayed at home.
It was raining. Therefore, I stayed at home.

我们不能把讲述结果的子句放在解释原因的子句前面。

So I stayed at home, it was raining. （错误）

和使用 because 来表达的意思是一样的。

Because it was raining, I stayed at home.

以下是更多的例子：

She was tired so she went to bed early. 她累了，所以很早就睡了。
The train was delayed. Therefore, we were late for the meeting. 火车晚点了。因此，我们开会迟到了。
We were hungry so we stopped for a snack. 我们饿了，所以我们停下来吃点心。
