SAT填空题中的因果关系
<p> 今天我们要给大家讲解的是<span word="SAT">SAT</span>填空题中对逻辑关系的考察，<span word="SAT">SAT</span>填空题部分虽然对逻辑关系有所考察，但由于考试本身主要面向高中学生，所以逻辑关系非常简单、直接，而且所有逻辑关系必然有明显的词汇使之得以体现。在此，留学专家仅以因果关系为例，对句子逻辑关系分析加以阐述。</p><p> 因果关系是逻辑推理中最基本的关系之一，而在<span word="SAT">SAT</span>填空部分的考察方式往往是句子给出原因或者结果，而让考生填充对应的结果或原因。比如：</p><p> 例1：<span word="Since">Since</span> <span word="the">the</span> <span word="island">island</span> <span word="soil">soil</span> <span word="has">has</span> <span word="been">been</span> <span word="barren">barren</span> <span word="for">for</span> <span word="so">so</span> <span word="many">many</span> <span word="years">years</span>, <span word="the">the</span> <span word="natives">natives</span> <span word="must">must</span> <span word="now">now</span> ______ <span word="much">much</span> <span word="of">of</span> <span word="their">their</span> <span word="food">food</span>.</p><p> <span word="deliver">deliver</span> <span word="import">import</span> <span word="produce">produce</span> <span word="develop">develop</span> <span word="utilize">utilize</span></p><p> 在例4中，<span word="Since">Since</span>体现出两个分句之间为因果关系，并给出原因为土壤很多年来都很贫瘠，而空格所要填的内容就是由于土地贫瘠而导致的结果，即当地人必须在土地贫瘠的情况下还要获得食物。因此，<span word="import">import</span>所表达的进口就非常符合这种因果的逻辑关系，所以为正确答案。而且，我们可以看出，其他的几个选项都不能和土地贫瘠构成因果关系，因而不是正确选项。</p><p> 例2：<span word="Given">Given</span> <span word="the">the</span> ______ <span word="state">state</span> <span word="of">of</span> <span word="the">the</span> <span word="published">published</span> <span word="evidence">evidence</span>, <span word="we">we</span> <span word="do">do</span> <span word="not">not</span> <span word="argue">argue</span> <span word="here">here</span> <span word="that">that</span> <span word="exposure">exposure</span> <span word="to">to</span> <span word="low">low</span>-<span word="level">level</span> <span word="microwave">microwave</span> <span word="energy">energy</span> <span word="is">is</span> <span word="either">either</span> <span word="hazardous">hazardous</span> <span word="or">or</span> <span word="safe">safe</span>.</p><p> <span word="inconclusive">inconclusive</span> <span word="satisfactory">satisfactory</span> <span word="definitive">definitive</span> <span word="immaculate">immaculate</span> <span word="exemplary">exemplary</span></p>
