BBC英语一分钟: 不定式表目的

How to use infinitives of purpose

 如何使用不定式表目的

Hi, I’m Dan from BBC Learning English, and today I’m going to talk to you about infinitives of purpose.

嗨,我是BBC英语学习的丹,今天我要讲的是不定式表目的。

English has something called the infinitive of purpose. We use it to explain why we do something. To explain why we do something is an infinitive of purpose. Why do we use it?

英语中有所谓的目的不定式,用于解释做某事的原因。解释为什么做某事就是目的不定式。为什么要用目的不定式呢?

Another example is: I went home to eat. We make our sentence: I went home, and then attach a full infinitive verb - to eat.

另一个例子:我回家吃饭了。我们看看这个句子:我回家,然后后面是一个带to不定式——吃饭。

This doesn’t work with nouns. For example: I went home to food.

后面不能跟名词。例如: I went home to food.

To use a noun we use for. I went home for food.

后面是名词是要用for:I went home for food.

Finally, we can also use for to talk about doing something to help someone. For example: I made this video for you to learn. You’re welcome!

最后,for也可以用于表示做某事帮助某人,例如:为了让你学习,我做了这个视频。别客气!
