在新东方我是跟着高嵩老师上课，他给我们讲的Sentence simplification题主要抓住逻辑关系，在15秒内解决问题。; D  Q& x" R7 b, u  H
意思就是抓住highlight部分中的表示关系的词，然后从选项中找出同样逻辑关系的关系词。就是那个选项。如果有两个选项具备与题目相同的逻辑关系，那么再分析。

5 n, Y. v0 J& i0 G* V( Jwww.xiaomaguohe.net根据高嵩老师的方法，先判断题型，很明显的句子简化。直接找关系词。

找关系词，不难找到reasoning，表示原因的逻辑关系。所以到选项中找关于原因的关系词。在B和C选项中分别有because表示原因，答案必定在其中，最后经分析，得出答案是B。

这是我在OG上找的两个例子。高嵩老师说，他不推荐Delta上的题，因为不是真题，所以不推荐，也不推荐任何题。但是我做了Delta和Lonman上的阅读才发现这个简化句子题问题很大。因为几乎所有题干的句子都没有关系词。按照高嵩老师的讲解，真题上大多数都应该有关系词，只有少数的没有关系词。
