How to use 'because', 'as' and 'since'

如何使用because, as和since

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

大家好!我是BBC英语教学的蒂姆,今天我要告诉大家三个有用的单词:because, as和since。

These are all used to give reasons.

这些都是用来给出理由的。

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.

because比as或since更常见,当我们想要专注于原因时就会用到它。我累了,因为我没有睡好。

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.

当我们想要把更多的注意力放在原因上时,我们可以把because从句放在句子的开头。因为我的床不舒服,我的背不好。

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.

As和since比because更正式,我们用它们来强调结果而不是原因。我希望汤姆把那本漫画带来了,因为我想向他借。面条很受欢迎,因为它们容易煮。

We often use as and since clauses at the beginning of the sentence. Just remember to add a comma. So, as our minute is up, I'll finish recording this video.

我们经常在句首使用as和since从句。记住要加逗号。我们的时间又到了,我要把这个视频录完。
