有一个妈妈把一个橙子给了邻居的两个孩子。这两个孩子便讨论起来如何分这个橙子。两个人吵来吵去,最终达成了一致意见,由一个孩子负责切橙子,而另一个孩子选橙子。结果,这两个孩子按照商定的办法各自取得了一半橙子,高高兴兴地拿回家去了。第一个孩子把半个橙子拿到家,把皮剥掉扔进了垃圾桶,把果肉放到果汁机上打果汁喝。另一个孩子回到家把果肉挖掉扔进了垃圾桶,把橙子皮留下来磨碎了,混在面粉里烤蛋糕吃。 从上面的情形,我们可以看出,虽然两个孩子各自拿到了看似公平的一半,然而,他们各自得到的东西却未物尽其用。这说明,他们在事先并未做好沟通,也就是两个孩子并没有申明各自利益所在。没有事先申明价值导致了双方盲目追求形式上和立场上的公平,结果,双方各自的利益并未在谈判中达到最大化。 试想,两个孩子充分交流各自所需,或许会有多个方案和情况出现。可能的一种情况,就是遵循上述情形,两个孩子想办法将皮和果肉分开,一个拿到果肉去喝汁,另一个拿皮去做烤蛋糕。然而,也可能经过沟通后是另外的情况,恰恰有一个孩子既想要皮做蛋糕,又想喝橙子汁。这时,如何能创造价值就非常重要了。 结果,想要整个橙子的孩子提议可以将其他的问题拿出来一块谈。他说:“如果把这个橙子全给我,你上次欠我的棒棒糖就不用还了”。其实,他的牙齿被蛀得一塌糊涂,父母上星期就不让他吃糖了。 另一个孩子想了一想,很快就答应了。他刚刚从父母那儿要了五块钱,准备买糖还债。这次他可以用这五块钱去打游戏,才不在乎这酸溜溜的橙子汁呢。 ()是沟通的最佳结果。

A. 能够最大程度的满足双方的利益
B. 能够满足自己的最大利益
C. 使对方获得的利益最大
D. 使对方获得的利益最少

Finally, the Christmas season is over. We can take a long breath, put up our feet, sip from a cup of good tea and relax. The frenzy, starting from Black Friday right after Thanksgiving until Christmas Eve, of gift shopping, buying, wrapping, giving, receiving, opening, returning... is exhaustive and time-consuming, but it takes place every year. There is considerable difference between the cultures in China and western countries when it comes to gift giving. In China, it is not polite to open a gift in front of the gift giver, and gift is only looked at after the guest has left. Here in America, gift givers always wrap their gifts, large or small, priceless or valueless, carefully and decorate them with colorful ribbons and little pretty paper flowers; and the lucky receiver is expected to open the gift right away in front of the giver, with great eagerness and curiosity, and should always express appreciation with the all time truthful comment, "this is just exactly what I wanted!" Well, as a matter of fact, most people would take their "always wanted" gifts back to the store to exchange for something they really wanted. Finding a gift for somebody, even a close family member, you"ll have to know what the person likes and shop for days before you can locate the perfect gift. But, still the person may not like the gift from you. Nowadays, stores would provide two copies of the receipts for anything they sell as a gift, one of which is included in the gift package so that the receiver can come back for an exchange. I know, it was unthinkable to cash out gift you get, but, times are different. Another good way to avoid all that shopping hassle is to purchase a gift card from one of the stores and send it to your niece, nephews, or a family member, so that they can get whatever they want or even keep the money.It is quite () for Chinese people to open the gift in front of the givers.

A. usual
B. normal
C. abnormal
D. unusual
