those for whom
It is also a world where some are left further and further behind - those who are not educated,those trapped in poverty and violence,those for whom equal opportunity is just a hollow phrase.

同时,现今世界,一些人越来越落后于时代.这些人没受过教育、深陷于贫穷和暴力、平等机遇对他们而言,仅是一句空话.

问题：
最后句话those for whom equal opportunity is just a hollow phrase.中those 后面的for我不太理解,这是什么用法?帮我分析下语法谢谢
答：这句话中的三个those是前面some的同位语,它们后边都跟了定语,第一个跟的是由who引导的定语从句,第二个跟的是过去分词短语trapped ...,第三个跟的是介词for+关系代词whom引导的定语从句.翻译不是很清楚了吗?for sb.对有些人而言,对某人来说.
再问： those不是some 的同位语吧,如果是的话,就不应该用those 而是that
再答： some= some people是复数，后面用are了看见了吗？ where引导定语从句=in which
再问： 可否细讲下？同位语从句的引导词只能是that
再答： 这里的同位语不是从句，就是一个代词those,只不过它后面跟了一个限制性定语从句。 它和the fact that the earth goes around the sun 是不一样的。 如Meeting my uncle after all these years was an unforgettable moment , ONE I will always treasure. one 是an unforgettable moment的同位语。
再问： 噢,It is also a world where some are left further and further behind 中where是什么用？
再答： 上面已经回答过了。定语从句，where=in which. 如:This is a place where you can ask me questions. Understand? Meeting my uncle after all these years was an unforgettable moment , ONE I will always treasure. A.that B.one C.it D.what one 是an unforgettable moment的同位语。可不要选A啊！
