大家好，欢迎收听 BBC 英语教学的 “地道英语” 节目。在每期节目中，我们都会介绍一个英语母语人士或讲英语流利的人会用到的表达。I'm Feifei. 

Phil
And I'm Phil.

在这期节目中，我们要介绍一个动词短语 “crank up”。我和 Phil 将先用英语为大家讲解它的用法，最后再由我用汉语进行归纳总结。

Phil
How are you, Feifei? You look tired.

Feifei
Oh, that's a bit rude! Although, it is true. I have a new neighbour – every time I try to go to sleep, my neighbour cranks up the volume of his music. It's driving me crazy!

Phil
Oh no! But that does give us a phrasal verb to learn in this programme – 'crank up'. It can mean 'turn up' – but can you tell us a bit more about it?

Feifei
Yes. So, it might actually help if you think about an old machine – a 'crank' is a handle that you turn to make something happen. When we use 'crank up', we mean to increase the intensity of something – like the volume on my neighbour's speakers.

Phil
And it's not just volume – it can be the intensity of anything. We often use it metaphorically, so you can talk about cranking up your efforts to do something. So, if I really want to get fit, I need to crank up the level of my workouts.

Feifei
Yes, that's right. Here are some examples of people using 'crank up'.

Examples
I'm doing a course at the moment, and my teacher has brought forward the date of the exam, and that's really cranked up the pressure. I've got so much to study in no time at all.

I've got a half marathon coming up, so I've really got to crank up my training. 

I'm going to Poland. I need to crank up my efforts to learn Polish.

Feifei
So, 'crank up' is a phrasal verb. Phil, what else do we need to learn about it?

Phil
OK, with phrasal verbs, it's always important to know where to put the direct object. With 'crank up' you can either put it between 'crank' and 'up', or you can put it afterwards. 

Feifei
So, when it's cold you can crank the heating up, or you can crank up the heating.

动词短语 “crank up” 的意思是 “调高，增强”，尤其是指 “增加某件事物的强度”。比如，“crank the volume up（调高音量）”。“Crank up” 中的单词 “crank” 作名词时的原意是老式机械设备上的 “曲柄”，这类零件通常用来调整输出的功率。所以，“crank up” 还可以用来比喻 “付出更多的努力”。比如，你想给你的朋友张莹加油打气，就可以对她说 “Hey Zhang Ying, you need to crank your effort if you want to make it!（张莹，想成功的话你可得再加把劲儿啊！）”

Phil
Hopefully this episode will help you crank up your vocabulary learning efforts. 

Feifei
Yes. And, we'll be back next time with another useful English phrase. See you! 

Phil
Bye.
