工会传统上被政府和经济学家看成是对贸易的一种限制,对贸易自由起到抑制的作用,但是,我觉得工会必不可少因为它通常是唯一能使工人不受剥削的保护。
我不同意,获取/使用工人和他们的工作是贸易的一个普通的组成部分,就象人类使用自然和原料资源一样。
The key term is "exploitation". This words has two slighly different meanings: (1) to use something for advantage, which applies to the word from RAVI,中文讲就是简单的使用获取; (2) To use something or someone UNFAIRLY for one's own advantage, which applies to Sevn,中文讲是剥削.
mygoalusa. Thank you for your excellent explaination. I really feel that this kind of problems are very diffcult. Since I will take the GMAT test and I do the lsat section just to practise my logic and reading comprehension, I sometimes do not pay enough attention to that kind of problems that are not contained in GMAT. But I do not know whether it is suitable.
