1、If you can’t take the heat, then get out of the kitchen.

受不了压力那就离开这个工作

‘If you can’t take the heat, then get out of the kitchen’ is actually a saying, or idiom which does not have anything to do with a kitchen.

If you can’t take the heat, then get out of the kitchen, means if you can’t handle the stress, or pressure then you should not be doing the job.

You can also say, if you can’t STAND the heat, then get out of the kitchen, it’s the same meaning.

2、In turn

轮流、对某事的回应

In turn is usually used when one action follows another action.

Here they said first they will tell Moriarty about Sherlock, then he will tell them about his criminal network.

I Paid 5 Pounds to the shop-keeper, he in turn, gave me a nice cap. All the school pupils in the class said their name in turn.

3、upper hand

略胜一筹

That’s right, upper means something which is higher than something else.

Actually this saying “upper hand” comes originally from poker. In poker you call the cards you are playing with your “hand”, so if you have the upper hand, it mean’s your cards are better than your opponents.

In normal life now we generally use this to mean you have the advantage over someone, you have a better strategic position than them.

A general fighting a battle would probably tell his captains “whatever we do, we must not give the enemy the upper hand.

We must take the high ground here, then we can use our advantage and win the battle.

4、Sat back and watched

冷眼旁观

Yes, in this part we hear the phrase “Sat back and watched”.

To sit back and watch really means to do nothing to interfere with or help, just see what happens. For instance I could say “If I see an old lady fall down in the street, I’m not going to just sit back and watch. I will rush over and help her.”

Or if you see some children bullying a smaller child, the teacher would not sit back and watch, they would go over and discipline the bullies. Teach them it’s wrong to do this.

5、bit by bit

一点一点，慢慢地

The sick man got better bit by bit. Every day I could see him looking a little happier and healthier.

We can also say little by little instead of bit by bit, which has the same meaning.

6、show his hand

出手、显示自己的计 划和内藏

In the end Sherlock said “I have to let him believe he’s defeated me, then he will show his hand.

The Army General we talked about earlier could also tell his captains.

“We must not show our hand until it’s too late for the enemy to react. This will ensure our victory!” Apple did not show their hand about their new iPhone until they were ready to sell it.

Then they held a show to tell the world.

7、everything but the kitchen sink

几乎所有东西

Everything but the kitchen sink means almost everything you can think of.

When Sally went off to college, she took everything but the kitchen sink.”
