A: 大家好! 欢迎来到这期的美语训练班! 我是杨琳!

Learn A Word # 1494

今天我们要学的词是immune. Immune is spelled i-m-m-u-n-e, immune. Immune的意思是免疫的，比如，immune system就是指免疫系统， immune disease 则是免疫系统疾病。Immune还可以指"免除的","不受影响的". Apple's OS X, which has long been considered immune to viruses, was recently hit by a malicious software called Flashback. 苹果电脑的OS X操作系统一向被认为百毒不侵，可是最近，该系统遭到一种名叫Flashback的恶意软件的袭击。The IMF says Africa's economy is expanding, but it is not immune to global slowdown. 国际货币基金组织说，非洲经济整体有所发展，但并不能完全不受全球经济放缓的影响。好的，今天我们学习的词是 immune，immune，immune...

A: 听见没有，You have to upgrade your Macbook! Mac is no longer immune to viruses. Kat, kat, kat! 你想什么呢?

B: Oh...Oh what? I'm sorry what?

A: 瞧你这走神的!认真点!我正在说给macbook下补丁呢!

B: 对对, I spaced out there for a second! 不过正好，下面的Popular American里面，我们就要来学学走神要怎么说!

Popular American

现在播送《流行美语》。Larry和李华明天要考试，今天一起复习，但李华一直没法专心。她今天会学到两个常用语：zone out和now you're cooking with gas。

LL: So Reaganomics were the economic policies of U.S. President Ronald Reagan---Li Hua? Are you listening?

LH: (Pause) 嗯?发生什么事了?

LL: Li Hua! How can you zone out when your final is tomorrow?

LH: Zone out? 你在说什么啊Larry?

LL: To zone out means to lose concentration and to not notice what's happening around you.

LH: 喔，你是说我分心吗?

LL: Yes. A 'zone' is an area. If you 'zone out', you mentally drift away from the place you are currently at, and go off into empty, dreamy space.

LH: 所以zone是指一个区域, zone out 就是走神。

LL: Yup. So stop zoning out! We still have a lot of studying to do!

LH: 好吧。那你告诉我，什么是supply-side economics?

LL: Supply-side economics argues that economic growth can be most effectively created by lowering barriers for people to produce goods and services (supply)--

LH: 比如说降低所得税。

LL: Hey! Now you're cooking with gas!

LH: Cooking--cooking with what?

LL: Now you're cooking with gas! It means now you understand what I'm talking about.

LH: 啊。Now you're cooking with gas 是指我终于跟上了，了解你在说什么。是啊，我还是懂一点点的。不过now you're cooking with gas和了解一件事情怎么能扯得上关系呢?

LL: This comes with a little bit of history. In the 1930's cooking became more convenient as the kitchen evolved from the old coal/wood range into the wood/gas combination. So when we say 'now you're cooking with gas', it means you've crossed the barrier and progressed!

LH: 真有意思。原来是1930年代煮饭从依靠炭和木头进化成依靠天然气，生活方便了许多。所以说now you're cooking with gas就代表我进步了。

LL: Yes, that is correct. Wow you're really cooking with gas now! Learning so fast.

LH: 哈哈对呀。我现在精神好多了。还是学习英文俚语比较有趣。

LL: But we have to keep going with Economics, or else we're both going to fail the exam tomorrow.

LH: 是啊。But if we keep talking about boring Economics, I'm going to zone out again!

LL: Hmm what should we do then...

LH: 要不这样!你先教我zone out 和now you're cooking with gas 的用法，让我变得有精神之后，我们再继续看经济学，怎么样?

LL: I guess that could work. Hmm....you seem to be able to use these two phrases already. Do you have any questions?

LH: 当然有。如果分心是zone out, 那很专注的时候就是I'm really zoned in, right?

LL: That's interesting. But no one says it that way. A lot of phrases are only used in one direction. Therefore, you can only say zone out, but there is no such thing as zone in.

LH: 啊，原来如此。分心是zone out, 但注意力集中时不能反过来说zone in.

LL: Right. What about "now you're cooking with gas?" Can you give me an example using that phrase?

LH: Even though I was zoning out at the beginning of this review session, I began to cook with gas.

LL: Hmm. The phrase 'now you're cooking with gas' is usually used together as one, so no words are changed. Therefore, we don't say that someone begins to cook with gas.

LH: 好麻烦。所以说，Now you're cooking with gas. 得要整句一字不露地用。通常是一个人对另一个人说，Now you're cooking with gas. 而不是用来形容第三者的。

LL: That's right. Now you're really cooking with gas! Do you think we can go back to Economics?

LH: 啊!我要回家了。今晚是美国偶像American Idol的决赛。拜拜!

LL: Wait! Li Hua!

MC: 各位听众，今天李华从Larry那儿学到两个常用语，一个是zone out, 是走神，发呆的意思;另一个是now you're cooking with gas. 指一个人开始进入情况了。这次《流行美语》播送完了，谢谢收听，下次节目再见。

A: Kat, 我可要批评你了，How could you zone out in the middle of the show?

B: I'm really sorry! I was thinking about all the things I want to say to my supervisor! 他今天早晨又让我去帮他买咖啡!我又不是给他跑腿的小时工!

A: 原来是这样!也许你可以跟他谈谈，说不定他根本就没觉得这是个事儿呢!

B: if he asks me to buy coffee again, I will throw it in his face! Yeah, yeah! I will do that! 不过大家先拿我当个模版，咱们来看看跑腿儿用美语怎么说!
