并列連詞so的用法說明

so用作并列連詞時主要表示結果，意為“因此”“所以”。如：

I was tired, so I went to bed earlier. 我累了所以早點睡了。

He took my shoes, so I couldn’t leave the house. 他把鞋拿走了，我出不了門。

It was very cold, so we had to wear warm clothes. 天氣很冷，所以我們得穿暖和的衣服。

按英語習慣，表示結果的so不能與表示原因的because套用，在使用時只能保留其中的一個。如：

那是一個難題，所以我最后才回答。

誤：Because that was a difficult question, so I answered it last.

正：That was a difficult question, so I answered it last.

正：Because that was a difficult question, I answered it last.
