掌握 so 和 therefore 的用法和區別

so 和 therefore 是兩個非常實用的連接詞。我們可以使用 so 和 therefore 來談論某件事情的結果。so 通常出現在句子的中間，而 therefore 則出現在一個新句子的開頭。相較於 so，therefore 更加正式。

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

我們不能把講述結果的子句放在解釋原因的子句前面。

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

和使用 because 來表達的意思是一樣的。

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. 火車晚點了。 因此，我們開會遲到了。
