句子转换的另一种形式是对原文的总结概括。Summary或者T/F/NG题目当中，有时候会出现原文和句子之间是总结概括关系。

Example 2:

原文：It has been proved that a rapid response leads to a great likelihood of arrest only if it is 1-2 minutes after a call is received by police. When the response time increases to 3-4 minutes, the likelihood of an arrest is substantially reduced.

题目：A delay of 1-2 minutes in response may have substantial influence on whether or not a suspected criminal is caught.

这道题目源自一篇讲反应速度的文章。原文中的两句话讲述的内容为，如果警察在接到电话后的1-2分钟反应，抓住罪犯的可能性就非常大;如果3-4分钟反应，拘捕的可能性就会降低。这样的意思在题目当中被概括为一句话，即延后反应一到两分钟会降低抓住罪犯的可能性。

Example 3:

Q4/Test 1/Cambridge V (T/F/NG):

4、The fact that children’s ideas about science form part of a larger framework of ideas means that it is easier to change them.

该句的定位由于符合顺序原则，许多同学还是能轻松定位到第二段，但是接下来确认信息的过程就让一些综合阅读理解能力相对薄弱的同学不能从容应对，因为对于larger的同义代换不能识别从而导致错误答案。

事实上，单词large被原文中不止一个单词替换，综合在一起，成就了larger的意思：

These misconceptions do not remain isolated but become incorporated into a multifaceted, but organised, conceptual framework, making it and … …

虽然没有确切的某个单词表达了larger 的意思，但multifaceted, but organised, conceptual三个词合起来则充分准确地表达了该意思，不能不称之为巧妙。

Example 4:

Q26/Test 1/Cambridge IV (Short Answer):

26、Which of the senses is best developed in cetaceans?

句中best developed 显然是关键词，但是无论按照顺序原则还是其他方法都很难准确定位到某个句子，因为完全被代换成了句子。在最后一段的首句中：

Although the senses of taste and smell appear to have deteriorated, and vision in water appears to be uncertain, such weaknesses are more than compensated for by cetaceans’ well-developed acoustic sense.

虽然看上去well-developed可以充当题目中best developed的同义代换，但笔者认为并非如此，二者在表达的程度上是有差异的，如何做出准确的判断还是有赖于对上述整个句子的理解，并且在和其他的感官发育情况做了对比之后，情况就更加清晰，答案是acoustic sense.

诚然，辨识出统一代换似乎能节约时间，提高效率，但考生们还是要和综合实力相结合，才能相辅相成，又快又准地完成解题过程。
