对于句子简化题，有一些题目如果句子不长，我们做题的基本原则就是：同义替换。找到原句中的关键的词在选项当中进行同义替换。例如：

B. The creation of human language has its origins in the language of animals.
C. The emergence of language distinguished early humans from other animals.
D. Humans and animals developed completed different systems of communication.

该题要求从选项中选择一个能够表达原文阴影句子核心信息的句子。很多同学采用翻译的方法做题，即首先翻译原句，然后逐个翻译四个选项。这种做法不仅浪费时间，而且对我们的读句子的能力要求极高。更好的做法是，首先判断句子的核心信息。这是考题当中为数不多的原句比较简单的句子释义题，原句的核心概念在于强调区分(apart from)。因此找到同义替换，即是C项当中的distinguished。
