“昂贵的代价”怎么说？

　　Cost an arm and a leg 昂贵的代价

　　Rob: Its great that youve come with me during our lunch break to do some shopping. I need to buy a suit to go to a wedding and I have to look smart.

　　Helen: 你需要买一套西装去参加婚礼，我们午饭休息的时候我能帮你参谋参谋，怎么样?大家都说我特会买衣服。Rob, 我觉得那个橱窗里展示的那件灰色西装上衣看上去挺适合你的。

　　Rob: Wow! It looks very smart indeed. It will make me look great!

　　Helen: Exactly! 你穿上一定非常帅!Lets go into the shop, 你一定要穿上试试!

　　Salesman: The colour suits you, Sir! I will see if I can find a smaller size so that it fits you perfectly.

　　Helen: You see, Rob... 售货员也认为这件衣服穿在你身上简直就没治了。不过我同意他说的尺码，如果再小一号儿就更合体了。Everybody will think you are a powerful man.

　　Rob: Wait Helen, this suit is not for me. Im reading this label; it costs an arm and a leg!

　　Helen: An arm and a leg!? 这也太可怕了 Rob. 你说你得付出一只胳膊和一条大腿才能拿到这件衣服?Rob 这可是21世纪，不是中世纪哟 not the Middle Ages! 售货员看上去也相当文明，he sounded like a nice man!

　　Rob: Dont worry, Helen. I will keep my limbs. In English, when we say something costs an arm and a leg we mean that it is very expensive!

　　Helen: So 在我们形容什么东西的价格太昂贵时，就可以说 cost an arm and a leg, 太贵了买不起。Thats a relief.

　　Rob: Lets hear some examples while I go back to my old clothes.

　　d like to travel all over Europe, but the air fare might cost me an arm and a leg.

　　You have to pay a lot of money to give your children a good education nowadays! A place in a top university costs an arm and a leg.

　　Rob: So, how do you use the expression an arm and a leg?

　　Helen: 当你想表示什么东西非常非常昂贵，你就可以说 it costs an arm and a leg.

　　Rob: Now, lets leave this expensive suit here and get out of the shop before the posh-sounding salesman comes back.

　　Helen: 咱们赶快走吧，要不然那个说话高雅的售货员马上就回来了，他肯定会瞧不起我们的。我看那边的那条围巾非得要我 pay a nail and an elbow. 那件红色连衣裙还不得 cost a foot and a knee... 啊, 再看这个包包! 肯定要 cost an ear and a hand...

　　Rob: What are you talking about, Helen!? We only say an arm and a leg! Quick, lets get out of here!

　　Helen: OK, OK! Bye.

　　Rob: Bye.
