TPO15
最后主旨题 有个选项

glacier formation

○If global warming melted the world's glaciers, sea level would rise about 60 meters worldwide.

请问红色的选项为什么不选，原文定位如下：
The total amount of ice is even more awesome if we estimate the water released upon the hypothetical melting of the world's glaciers. Sea level would rise about 60 meters. This would change the geography of the planet considerably.
有谁帮忙解释下么
MASS EXTINCTION
○There was a particularly large mass extinction that occurred around 250 million years ago at the end of the Permian period, whose cause could not be determined
原文定位：
There was one such event at the end of the Cretaceous period (around 70 million years ago). There was another, even larger, mass extinction at the end of the Permian period (around 250 million years ago). The Permian event has attracted much less attention than other mass extinctions because mostly unfamiliar species perished at that time.
同上问。。求解释啊求解释。。

主旨题很难这样子解释吧~
我觉得目前看来合理的解释这两个都是全文里面的一处细节~ 主旨题目是不应该选细节的

我记得冰川这道主旨题要求的是选出关于冰川对于地球水循环的作用还是过程来得.....LZ这个选项更循环有什么关系呢？

mass这道题目Lz是不是没认真看啊....

但从选项就可以看出是不对.....

There was a particularly large mass extinction that occurred around 250 million years ago at the end of the Permian period, whose cause could not be determined

既然无法被确定，怎么去解释mass extinction？不明白LZ哪里想不明白

第一题：
题目是
glacier is part of Earth's hydrologic cycle.
可是我觉得
○Glaciers, which at present contain 80 percent of Earth's freshwater, form when accumulated snow is compressed and recrystallized into ice over a period of years.
○When glacial ice reaches a depth of 30 meters, the weight of the ice causes ice crystals at the bottom to flow, and the resulting movement of the glacier carves the landscape.
也跟循环没啥关系饿。。  求教。
第二题
嗯。有理。
