2013年6月15日托福阅读考题解析 　　第一篇文章indus文明的衰落 　　第一部分讲一个古文明(印加)的衰落。 这个文明的衰落不是因为战争;也不是因为某一群人的定居，因为那群人是在衰落之后才到哪个地方去的。 　　第二部分讲overgrazing和deforestation 可能是原因。 因为人们到哪使用fireplace以及一些其他的自然资源。 　　第三部分另一个原因可能是降雨量。科学家发现，那个地方衰落的时候正好是降雨量减少的时候。还具体描述了在这段时期降雨量发生的变化，给出很多数据。 　　第四部分另一个原因是城市的繁荣跟周边rural地区食物的productivity有关。由于气候的原因，rural地区食物产量降低，大城市不能从周围地区获得食物就衰落了。同时，小地方没大城市衰落那么快，但最后变成了village。整个文明也就衰落了 　　解析：该篇文章为因果解释类文章，先描述现象印加文明的衰落然后解释不同的原因。典型的托福阅读cause-effect类文章。大家按照不同的理论整理文章结构即可。具体内容请大家参照如下文章。 　　Decline Of Harappan Civilization: 　　The Indus Valley Civilization dated from 3300 1300 BCE that was located in the north western region of the Indian Subcontinent.

During its late phase between 2000 and 1700 BC The Indus Valley Civilization as a distinct entity gradually ceased to exist. Historians have different opinions regarding the causes of the decay and disappearance of the Harappan culture. Various causes have been ascribed for its weakening and then decay: Increase in rainfall, earthquake, decrease in fertility of soil, floods, Aryan invasion, disease etc. Mortimer Wheeler pointed out that the Harappan culture was destroyed by the Aryans. The Aryans were more skilled at warfare and were powerful than the Harappans. But there is very little evidence on this opinion. 　　.Another school of thought relates the demise of the Indus vall
