2015考研英语阅读动物如何感知时间

　　Healy先生推断，动物CFF的主要限制来自于其体型及其新陈代谢速度。体型小意味着大脑中信号传递速度快。高代谢率意味着更多的能量处理信息。然而，一个文献检索显示之前没人研究过这个问题。

　　Fortunately for Mr Healy, this search also showed that plenty of people had looked at CFF inlots of species for other reasons. Similarly, many other people had looked at the metabolicrates of many of the same species. And size data for species are ubiquitous. All he had todo, therefore, was correlate and repurpose these results. Which he did.

　　幸运的是，对Healy先生来说，很多人为了别的原因也研究了许多物种的CFF。同样的，许多人也研究了许多上述物种的新陈代谢速率。物种体型大小的数据到处都是。这么一来，他需要做的就是关联并重新利用这些结果。他这么做了。

　　To simplify matters he looked only at vertebrates34 species of them. At the bottom endof the scale was the European eel, with a CFF of 14Hz. It was closely followed by theleatherback turtle, at 15Hz. Tuataras clocked in at 46Hz. Hammerhead sharks tied withhumans, at 60Hz, and yellowfin tuna tied with dogs at 80Hz. The top spot was occupied bythe golden-mantled ground squirrel, at 120Hz. And when Mr Healy plotted his accumulatedCFF data against both size and metabolic rate , he found exactly the correlations he had predicted.
