1. Settle the score
报仇，报复
等同于revenge, which involves hurting or punishing someone who has hurt or harmed you.
settle本身带有“了结，清算，结束争端”的含义，而score除了表示“得分”以外，还指"欠账; 宿怨"，所以组合起来settle the score就是 “清算欠的旧账（也可比喻做过的坏事），了结这段宿怨”，简而言之就是“报复，报仇"。
The groups had historic scores to settle with each other.
这两个集团之间有几笔旧账要了结。
She said she would settle the score for Tom.
她说她要为汤姆报仇。
2. We're on a clock.
我们没多少时间 / 我们要争分夺秒
It means we don't have much time availible / we need to hurry up.
be on a clock 争分夺秒
You are on a clock and hurry up, or you will be late !
你已经没多少时间了，赶快！不然迟到了！
同样表示”争分夺秒“带clock的短语还有，
fight the clock
race the clock
动词 v + against the clock
记得它们clock前面接的都是the。这些搭配一样可以套用在上面同一例句里面，
Fight the clock and hurry up, or you will be late !
Race the clock and hurry up, or you will be late !
Go against the clock and hurry up, or you will be late !
3. Save your starwood points.
喜达屋集团的酒店就算了。
如果不看字幕的话，我们可能要多揣摩一会儿才能翻译这个意思。因为save在这里的用法不像save time, save money或者save my life那样的直译。
save作为动词还可以指”避免“，Save your starwood points直译应该是“避免喜达屋集团的酒店”，就是指他不喜欢喜达屋集团的酒店。当然这样说会很生硬，若口语化后说“喜达屋集团的酒店就算了”显得顺很多。
所以在一定语境前提下，save something指 “......就算了”，例如
Oh come on, save the shopping, it's so boring.
购物就算了，那太无聊了。
Save the toy and i prefer flowers.
送玩具就算了，我更喜欢鲜花。
save还有一些很常用的口语，
Save your strength for the hard work you'll have to do later.
留着点儿劲儿，你一会儿还得干重活儿呢。
Save your breath，I‘ve already known you’re lying.
你就省省吧！我早就知道你在撒谎。
4. The Sheraton's not my scene.
喜来登酒店不是我最爱。
scene在俚语当中有“爱好”的意思。If you say that an activity or place is not your scene, you mean that you do not like it or enjoy it.
be not my scene （活动/地方）不合我意
Lying on the beach all week isn't my scene.
我不喜欢整个星期都躺在沙滩上。
This restaurant's not her scene.
这家餐厅不合她意。
5. Live it up, pal
尽情逍遥吧，伙计
live解作“享受生活”，live it up固定搭配指“尽情逍遥，纵情享乐，狂欢一场”，口语化的enjoy yourself.
it's your birthday, so let's live it up!
今天你生日，我们尽情玩乐一下吧！
Let's go to Europe for two weeks and live it up.
咱们到欧洲两个星期,好好享受一番。
There is no reason why you couldn't live it up once in a while.
偶尔放纵一下也无妨。
