大漠拆句-6

大漠拆句：
继大漠点词之后又一个新的尝试，精选14-15年托福阅读真题中出现的句子简化题并进行拆解精析，最终的目标是希望能够帮助同学们掌握长难句的读法，在有词汇量的基础上快速把握句子主干。最终轻松搞定句子简化题，但更重要的是掌握一般性的长难句的读法，为所有的阅读考试扫平障碍。目前正在积累备课中，未来一到两月备课成熟以后上线。

The Brain Size of Bottlenose Dolphins

Among the more plausible suggestions for large brain size are that the complexity of processing high-frequency echolocation information requires the development of large centers in the cerebral hemispheres, and/or that the degree of sociality exhibited by many species, in which individual animals recognize and have particular long- and short-term relationships with a number of other individuals, has favored the evolutionary development of a large, complex brain.

主干：

语法意义上的主干
Among the more plausible suggestions for large brain size are that A , and that B.

这里有一个比较重要的结构：among .... are ... ，本身不难，但经常和嵌套的长难句结合，需要注意

A 主干
the complexity of processing information require the development of large
centers in the cerebral hemispheres,
B 主干
and the degree of sociality has favored the evolutionary development of a large brain.

非主干成分:

• 表语从句

... that the complexity of processing high-frequency echolocation information ......, and that the degree of sociality exhibited ...

• 非谓语动词短语作定语

... exhibited by many species ...

• 定语从句

... in which individual animals recognize and have particular long-and-short term relationships with a number of other individuals,

• of 名词性短语

• the complexity of processing high-frequency echolocation
• the development of large centers in the cerebral hemispheres
• the degree of sociality
• the development of a large , complex brain

翻译：

在更为靠谱的对更大脑容量的解释中，有A 和 B两个，A是处理高频率的回声定位信息需要有发展出更大脑半球，B是许多物种所展现出来的社交性（个体动物认识并和其他个体发展出或长或短的关系）支持了一颗更大、更复杂的大脑的进化。

翻译仁者见仁，这里只是抛砖引玉作为参考

真题实战

A. It is plausible that the development of high-frequency echolocation, large centers in the cerebral hemispheres, and/or a high degree of sociality may have contributed to the development of large brains.
B. For an animal to recognize and have long- and short-term relationships with a number of other individuals, the animals must develop large centers in the cerebral hemispheres.
C. Processing high-frequency echolocation information may have required a large, complex brain that already had the capacity to develop and recognize long- and short-term social relationships with multiple other individuals.
D. The demands of processing high frequency echolocation information and/or a high degree of sociality may have favored the evolutionary development of a large, complex brain.

答案：D

解释：关于简化题的做法日后专门说，这里只是简单提一下最核心的原则：主干对主干。D选项的主干为( The demands of processing high frquency echolocation information ) and ( a high degree of sociality ) may have favored the development of a large brain，主干与原文一致;
A主干：( the development of high-frequency echolocation ), ( large centers in the cerebral hemispheres ), and ( a high degree of sociality ) may have contributed to the development of large brains
B主干：the animals must develop large centers in the cerebral hemispheres。
D主干：processing high-frequency echolocation information may have required a large , complex brain
