　　However, when two monkeys were placed inseparate but adjoining chambers, so that eachcould observe what the other was getting in returnfor its rock, their behavior became markedlydifferent.

　　译文：但是，把两个猴子安置在分隔但相邻的两个房间里，这样它们能够看见对方用石头换回什么东西时，它们的行为就会变得明显不同。

　　点睛：本句的主干为...behavior became…different。句首是由when引导的时间状语从句，so that引导目的状语从句，而在该从句中又含有一个what引导的宾语从句。adjoining是形容词，指“相邻的;隔壁的”。in returnfor有“酬谢;作为…的报答”的意思，在本句中应理解为“换回来…”。

　　He gave her some roses in return for her kindness.

　　他送了她一些玫瑰以答谢她的好意。
