Question

如题

Answer 1

这是相关的台词：
(Rachel picks up the next gift.)
Rachel: Who's this from?
Chandler: Oh, that's Ross's.
Rachel: Oh... (opens it)... (sees it is a pin) Oh my God. He remembered.
Phoebe: Remembered what?
Rachel: It was like months ago. We were walking by this antique store, and I saw this pin in the window, and I told him it was just like one my grandmother had when I was a little girl. Oh! I can't believe he remembered!
Phoebe: Oh, it's so pretty. This must have cost him a fortune.
Monica: I can't believe he did this.
Chandler: Come on, Ross? Remember back in college, when he fell in love with Carol and bought her that ridiculously expensive crystal duck?
(Everyone looks at him. He realizes he just spilled the beans about Ross's crush on Rachel. You can hear this entire classic scene by clicking here.)
Rachel: What did you just say?
Chandler: (panicked) ahem... um... Crystal duck.
Rachel: No, no, no.... the, um, the... 'love' part?
Chandler: (stuttering incoherently) F-hah.... flennin....
Rachel: Oh.... my God.
Chandler: (rubbing his temples) Oh, no-no-no-no-no....
Joey: (pats Chandler on the leg) That's good, just keep rubbing your head. That'll turn back time.

ross送给rach的礼物是有一次他俩逛街的时候经过一家店，当时rach看到一个胸针，她说长得很像她小时候她祖母带的，结果没想到ross记得这件事情，就把那个胸针作为生日礼物送给了rach。然后pheobs和mon都说这个肯定非常贵，不敢相信他居然花了那么多钱买个胸针送给rach。chan和ross是大学同学，然后他觉得这个没什么可惊讶的，他说拜托！这可是ross！当年他在大学里跟carol热恋的时候不是还给她买过一个贵得离谱的水晶鸭子吗？！
这句话其实就是把rach和carol放到了同等的地位，觉得给她们买东西是一回事。意思就是ross对rach就像他对carol一样，是爱情的关系。所以就露馅了，rach就知道了。

Answer 2

罗斯买了个很贵重的胸针给瑞秋当生日礼物，别人都在感慨，结果老钱说漏嘴称罗斯和卡萝相恋时，罗斯买了个昂贵无比的水晶鸭给卡萝，潜台词就是说罗斯对自己爱上的女人都很大方，于是瑞秋就发现了。

Answer 3

钱德说“大学时罗斯爱上卡萝时就给她买了个很昂贵的水晶鸭”，是在类比这次罗斯给瑞秋送礼物，意思是说，罗斯只有在爱上某个女人的时候才会这么用心，而且买很昂贵的礼物。钱德的潜台词就是“罗斯这次因为爱瑞秋而买了个很用心很昂贵的胸针，就像上次罗斯爱上卡萝时买的昂贵水晶鸭一样”。
