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<span word="is">is</span> <span word="most">most</span> <span word="probably">probably</span> <span word="a">a</span> <span word="function">function</span> <span word="of">of</span> <span word="the">the</span> <span word="correlation">correlation</span> <span word="between">between</span> <span word="red">red</span> <span word="meat">meat</span> <span word="and">and</span> <span word="heart">heart</span> <span word="disease">disease</span>.是说<span word="high">high</span> <span word="iron">iron</span> <span word="level">level</span>于<span word="heart">heart</span> <span word="disease">disease</span>之间的关系是<span word="red">red</span> <span word="meat">meat</span>与<span word="heart">heart</span> <span word="disease">disease</span>之间有关的结果那到底是认为<span word="high">high</span> <span word="iron">iron</span> <span word="level">level</span>和<span word="heart">heart</span> <span word="disease">disease</span>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：<span word="red">red</span> <span word="meat">meat</span>引起心脏病 <span word="red">red</span> <span word="meat">meat</span>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<span word="ETS">ETS</span>重复两次的短语<span word="well">well</span> <span word="established">established</span>，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<span word="Implicit">Implicit</span> <span word="causal">causal</span> <span word="claims">claims</span>和<span word="gratuitous">gratuitous</span> <span word="assumptions">assumptions</span>，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<span word="red">red</span> <span word="meat">meat</span>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：</p>
