文字稿

Hi, I’m Tim from BBC Learning English. Today I’m going to tell you about three useful words: because, as, and since.

These are all used to give reasons.

Because is more common than as or since and we use it when we want to focus on the reason.

I’m tired because I didn’t sleep very well.

When we want to give extra focus to the reason, we can put the because-clause at the beginning of the sentence.

Because my bed is uncomfortable, I’m getting a bad back.

As and since are more formal than because and we use them to focus on the result rather than the reason.

I hope Tom’s brought that comic as I wanted to borrow it from him.

Noodles are popular, since they’re easy to cook.

We often use as and since clauses at the beginning of a sentence. Just remember to add a comma.

So, as our minute is up, I’ll finish recording this video.

用法總結

1. 「Because」 比 「as」 和 「since」 更常見。我們用 「because」 來強調事情的原因。

  • I’m tired because I didn’t sleep very well.

如果想要額外強調原因,可以將 「because” 引導的從句放在句首。

  • Because my bed is uncomfortable, I’m getting a bad back.

2. 「As」 和 「since」 比 「because」 更為正式。我們用 「as」 和 「since」 來強調事情的結果。

  • I hope Tom’s brought that comic as I wanted to borrow it from him.
  • Noodles are popular, since they’re easy to cook.

「As」 和 「since」 引導的從句也常用於句首,注意不要忘記在從句後加逗號。
