GRE的阅读文章信息繁多，句子往往长而复杂，讲课要做到面面俱到，广而有深度，值得探讨。上海前进进修学院GRE班采用详细的书面注释结合课堂重点讲解，再加email答疑的办法，力求实效。下面的例子出自1992年2月GRE。题目的解释出自《中高级英语考试词汇捷径》(上海远东出版社出版)编著者、上海前进进修学院GRE班教师李蒙恩。(前进GRE秋季班于200x年9月开课；学院有住宿)　

(1st par.) The more that is discovered about the intricate organization of the nervous system, the more it seems remarkable that genes can successfully specify the development of that system. Human genes contain too little information even to specify which hemisphere (半球) of the brain each of a human’s 1011.neurons (神经元) should occupy, let alone (更不用说) the hundreds of connections that each neuron makes. For such reasons, we can assume that there must be an important random factor (随机因素) in neural development, and in particular, that errors must and do occur in the development of all normal brains.

【阅读技巧】For such reasons,是个信号，表明前面的Human genes contain too little information…that each neuron makes均是reasons。


【题目】21. Which of the following best describes the organization of the first paragraph?
(D) An observation is made, specifics are provided to support it, and a generalization is derived.
【注】The more that is discovered about the intricate organization of the nervous system, the more it seems remarkable that genes can successfully specify the development of that system. [An observation is made 发表评论/提出看法]

Human genes contain too little information even to specify which hemisphere of the brain each of a human’s 1011.neurons should occupy, let alone the hundreds of connections that each neuron makes. 　 [specifics are provided to support it 提供细节以支持评论/看法]

For such reasons, we can assume that there must be an important random factor in neural development, and in particular, that errors must and do occur in the development of all normal brains. 　 [and a generalization is derived 引出推论。　注意：we can assume that there must be…中的assume以及must]

特别注意：(A) A specific case is presented, its details are analyzed, and a conclusion is drawn from it. 是不对的！
