if one received a grape without having to provide her token in exchange at all, the other either tossed her own token at the researcher or out of the chamber, or refused to accept the slice of cucumber.

　　① In the world of capuchins, grapes are luxury goods (and much preferable to cucumbers).

　　② So when one m&111nkey was handed a grape in exchange for her token, the second was reluctant to hand hers over for a mere piece of cucumber.

　　③ And if one received a grape without having to provide her token in exchange at all, the other either tossed her own token at the researcher or out of the chamber, or refused to accept the slice of cucumber.

　　④ Indeed, the mere presence of a grape in the other chamber (without an actual m&111nkey to eat it) was enough to induce resentment in a female capuchin.

　　参考译文：

　　①(现象：分1) 在卷尾猴的世界里，葡萄是奢侈品(比黄瓜受欢迎得多)。

　　②(结果：分2)所以当一只猴子用一个代币换回一颗葡萄时，第二只猴子就不愿意用自己的代币只换回一片黄瓜。

　　③(并列：分3)如果一只猴子根本无须用代币就能够得到一颗葡萄的话，那么另一只猴子就会将代币掷向研究人员或者扔出房间外，或者拒绝接受那片黄瓜。

　　④(递进：分4)事实上，只要在另一房间出现了葡萄(不管有没有猴子吃它)，都足以引起雌卷尾猴的怨恨。
