TPO8第三篇第二题
我选的是D the river of mars began to dry up about 4 billion years ago
第一段最后一句不是说 runoff channels on mars是4billion年以前的事情了潜在的意思不就是说 4billion年以后river就dry up 了么?
而且个人觉得B选项实在有点勉强:large amounts of rain once fell on parts of mars
large amounts of和 parts of 都没提到啊

D肯定是错的.原文说河道形成于四十亿年前是说那会还有水怎么会dry up了呢?请注意4 billion years ago指的是一个时间点.
B是一个推断文中说过河道承载了雨水可以推断出有降雨.而河道本来就是在火星的“southern highlands”上找到的那当然是PARTS OF.large amounts of神马的可以无视~
