11. Such variations in size，shape，chemistry，conduction speed，excitation threshold，and the like as had been demonstrated in nerve cells remained negligible in significance for any possible correlation with the manifold dimensions of mental experience.(5)

　　难免类型：复杂修饰

　　译文：类似于这些已经被在神经细胞中证明的在大小、形状、化学过程、产生的速度、兴奋阈值及其类似的方面上所发生变化，当他们被用来与大脑的体验以可能的方式联系起来的时候，他们在重要性上仍然是微不足道的。解释：即使是初练难免的人其实也很熟悉such thing as something这样的语言方式，可是当中间的小东西thing 居然变成了一个长达十二个单词的大东西的时候，实在令人搞不清后面的as 及其后的something 到底为哪方神圣。再加上以such as 为中心的长主语距离系动词remain太远，更增加了本句的难度。请读者反复阅读，直到读出这样的感觉：顺序阅读原文时，原文似乎就是几大块，就好像是such things as a remain negligible in a certain sense.

　　12. It was possible to demonstrate by other methods refined structural differences among neuron types ; however , proof was lacking that the quality of the impulse or its condition was influenced by these differences , which seemed instead to influence the developmental patterning of the neural circuits .(5)

　　有可能通过其他方法来证明神经元种类间的细微的结构差异;可是，这样的证据是缺乏的，即神经冲动的性质或者状态是受这些差异所影响的，而这些差异看起来却能影响神经网络的发育模式。难免类型：复杂修饰、倒装 ◎大宝考研版权所有，拒绝转载◎pURxtNfCCe

　　解释：与很多人的印象相反，lack从来就不能作形容词，它只有动词或名词的词性。其形容词的形式是lacking,意思是缺乏的、不足的。本句的在 however 之前和之后的两个分句，是两个倒装结构，前一个是小倒装，正常语序是：to demonstrate refined structural differences among neuron types by other methods: however后面是个大倒装，lacking之后的that引导的同位语人名是修饰主语proof的，但是因为它太长，所以为了避免头重脚轻，被放到lacking之后，正常的语序应该是proof that the quality of ..was lacking

　　意群训练：It was possible to demonstrate by other methods refined structural differences among neuron types; however, proof was lacking that the quality of the impulse or its condition was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits.

　　13. Although qualitative variance among nerve energies was never rigidly disproved，the doctrine was generally abandoned in favor of the opposing view，namely，that nerve impulses are essentially homogeneous in quality and are transmitted as "common currency" throughout the nervous system. (4)

　　尽管在神经能量上存在着质的不同，这一点从来都没有在严格的意义上被反对过，但是以上教条通常被抛弃掉，而转向相反的观点，即：神经冲动从根本上本质相同，而且被当作“一种普通流”在整个神经系统中传播。

　　难句类型：复杂修饰、双重否定

　　解释：前半个分句中有一个双重否定，was never rigidly disproved,这种表示法用中文说出来还是比较好懂的，原因是我们熟悉中文的这种表示法，但在英文中出现，因为在以前的学习中见得少，所以感觉上很别扭。因此，同学们的任务，就是通

　　过反复阅读此类句子来熟悉这样的英语。其实在英文表达中，很多双重否定与中文表达是样的，表示肯定;如not unlimited就等于limited。但是值得读者注意的是在GRE和GMAT 这两种对考生的逻辑有苛刻要求的考试中，如果这种双重否定中所涉及的概念不是 dichotomous(即二分法的词汇，比如上面例子中的 limited 和 unlimited)，则双重否定不一定表示肯定;比如本例中的not disprove, 不能理解为agree， 不反对者中，的确有人会同意，但通常心存疑虑，随大流者居多。不但如此，大双重否定中加上限定词以后，在否定的范围上也有所变化，如本句的be never rigidly disproved，没有完全被反对，不能理解为从来都被严格支持的，而应该理解成从来都可能有人支持的。综上所述，对双重否定的句子，简单的把其置换为肯定，不是最精确的理解。而最好的办法，就是通过多读、多练来熟悉其语言表达及其逻辑方式，按照其字面的表达理解成没有完全否定，然后大脑中反应出其目前的生存状态是一个仍未消失的状态;这种理解才是在考试现场既快速又精确的理解。运用前面所说的用合理化原则中的取非读法，可以很容易的读出作者在后半个分句中想说前面的那种观点被反对了。但是，初学者会对这个分句中的something be abandoned in favor of something else这种语言表达感到突然，如果理解成因为喜后者而抛弃了前者，虽然也能说得通，但是其实原文从来没有这种因果关系，in favor of强调的是这两种动作的同时性;抛弃了前者，而转向后者， namely之后的内容是前面的opposing view的同位语。

　　意群训练：Although qualitative variance among nerve energies was never rigidly disproved, the doctrine was generallyabandoned in favor of the oppsing view, namely, that nerve impulses are essentially homogeneous in quality and are transmitted as "common currency" throught the nervous system.

　　14. Other experiments revealed slight variations in the size，number，arrangement，and interconnection of the nerve cells，but as far as psycho neural correlations were concerned，the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences. (4 -)

　　尽管其他实验显示在神经细胞的大小、数量、排列和相互连接上有一些小的差异，但是就心理-神经的关系而言，这些感官区域彼此之间的明显的相似性看起来比起微小的差异更为令人注目。

　　难句类型：复杂修饰、插入语

　　解释：在前后两个分句之间有一个插入语as far as psychoneural correlations were concerned。在后面的分句中，主语the obvious similarities之后的、修饰主语的成分较长、以至于有很多读者看到相隔很远的more remarkable than时一下子反应

　　不过来是什么比后者更明显。其简化形式应为：similarities seemed more remarkable than differences。意群训练：Other experiments revealed slight variations in the size, number, arrangement, and interconnection of the nerve cells, but as far as psychoneural correlations were concerned, the obvious similarities of these sensory fileds to each other seemed much more remarkable than any of the minute differences.
