英文词汇教学A knee-jerk reaction 本能反映
Neil在菲菲身上做起了医学试验。他为什么要用榔头砸菲菲？听节目，学习一个表达“本能反映”的常用搭配。

Neil
Hello and welcome to Authentic Real English, I'm Neil and joining me is Feifei…

Feifei
大家好。

Neil
I've got a medical experiment to perform on you in this programme, Feifei.

Feifei
Righhhhht…

Neil
Come on – it's for our listeners. We've got an expression which means to react to something without thinking about it carefully first. So, cross one leg over the other, like that.

Feifei
可是你拿个榔头，这是要干什么？

Neil
Keep calm – it's OK, I'm not going to hurt you. And I'll just tap your knee… And… it worked!

Feifei
Yes Neil, well done. You've just tested my reflexes. 你刚才检查的是我的膝跳反映，也可以被叫做膝跳反射。 When you hit my knee with the hammer, my leg kicked automatically. I didn't even think about it.

Neil
It was a knee-jerk reaction. And in English we can say that someone has a knee-jerk reaction when they act after an event without thinking carefully.

Feifei
Let's hear some examples of 'knee-jerk reaction'.

Examples
He left his wife after he saw her having a drink with another man but it was a knee-jerk reaction. He'll be back.

Putting up interest rates because of inflation is a knee-jerk reaction. They haven't thought of the other consequences.

Feifei
A knee-jerk reaction 本能反映。Acting automatically, without thinking about the consequences.

Neil
Let's try that again with the other knee. Here we go… Argh – you kicked me in the face!

Feifei
Sorry Neil – it was just a knee-jerk reaction.

Neil
Ow…

Both
Bye!
