解析:根据关键词我们定位到文段的中间部分:Mars Global Surveyor data released in 2003 seem to indicate that the Martian surface contains too few carbonate rock layers-layers containing compounds of carbon and oxygen-that should have been formed in abundance in an ancient ocean.这道题可以当做事实信息题去做,但注意不是原文的简单重复,suggest 是原文中indicate的同义转换,我们只要找到what就好了,原文that后面是重点,出现了too few, should have, 情感态度推测一下,持否定态度,也就说说形成 an ancient ocean不太可能,我们看选项,A中说Ancient oceans on Mars contained only small amounts of carbon.主客体与原文矛盾,排除;B选项 The climate of Mars may not have been suitable for the formation of large bodies of water.说不适合形成大量的水,持否定态度,符合原文,保留;C选项Liquid water may have existed on some parts of Mars' surface for long periods of time.相关句中未提及,排除;D选项The ancient oceans that formed on Mars dried up during periods of cold, dry weather. 说的是ancient oceans没有,而不是原来有后来干涸了,与原文不符,排除,所以正确答案为B。

  不管正推还是逆推,关键是要基于原文进行推断,这就是我们要从事件发展这条水平轴上进行推测的原因,不然从一条射线的某点,空间范围内进行延伸,你会得出无数条直线,判断我们做的正确与否,关键就是能不能在原文中找到相应的依据,希望同学们在做完推断题的时候回到原文中标出出题依据,逐渐提升自己做题的敏感度和正确率,最后考出好成绩。上海雅思代考|替考|广州雅思代考|深圳雅思代考
