研英长难句翻译真题词汇详解：（20）
长难句：however,when two monkeys were placed in separate but adjoining chambers, so that each could observe what the other was getting in return for its rock, their behaviour became markedly different.重点词汇：so that,markedly
■答案■
1、长难句： 但是，当两个猴子被放在隔开但相邻的两个房间里，能够互相看见对方用石头换回来什么东西时，猴子的行为就会变得明显不同。
分析： 本句是一个复合句，开始是when引导的时间状语从句，其中包含so that 引导的目的状语从句，而observe后面又是what引导的宾语从句；最后是主句their behavior become markedly different。
2、so that是一个连接词，在英语中十分常见，可以表示目的。how do you raise your children so that they will have healthy relationships?（你怎样培养孩子，以便使他们能够建立健康的个人关系呢？） markedly意为“明显地，显著地”，其形容词形式为marked。he showed a marked lack of interest.（他表现出明显的兴趣不足。）
