      析题:仔细读过,发现这道题有点绕,很多考生曾经有过这样的困惑:我没有理解最后一句话的意思ismostprobablyafunctionofthecorrelationbetweenredmeatandheartdisease.是说highironlevel于heartdisease之间的关系是redmeat与heartdisease之间有关的结果那到底是认为highironlevel和heartdisease之间有没有关系阿?再读之下,我们会发现其实做了一个顺接推论:redmeat引起心脏病 redmeat里面还有大量的铁 高铁引起心脏病,就是这么一个简单的推论过程,关键认清谁推出谁,就要在审题时注意到关键的这么看似不经意却被友好的ETS重复两次的短语wellestablished,也就是说大量红肉与心脏病之间一定有联系是不容质疑的论据,即本题论据是不容批驳的,关键问题在于由论据推导出结论的时候犯了Implicitcausalclaims和gratuitousassumptions,因而我们就可以以次展开攻击。很多来自网上的文章和提纲在本题上颠倒了推导对象,把高铁引起心脏病作为论据来推出redmeat引起心脏病,结果导致文章失误。下面读者可通过以下范文检验一下该论证过程和思路:
