【原文】 This occurs when an individual learns to do things that produce rewards in his environment and learns not to do things that produce punishments. 【参考译文】 当一个人在他的环境中学会做能产生回报的事情且学会不做会产生惩罚的事情时，这种情况就会发生。 【难点分析】 在翻译时，需知“that produce rewards in his environment”和“that produce punishments”都为that引导的从句分别作前后出现的两个“things”的后置定语，故可采用后置定语前置的方法来进行翻译。
