The tiger moth, indeed, is a clear example of a concept that many predators intuitively understand that creatures with the brightest coloration are often the least suitable to eat.
网友理解正确,整个黑体部分作 concept 的同位语,而 that creatures with the brightest coloration are
often the least suitable to eat 是
understand 的宾语。原分析有误。
1. concept 是一种“概念、观念”,捕食动物不可能理解、懂得一种抽象的概念,这就是排除定语从句的原因。而是有这样一种概念客观存在着,那就是:许多捕食动物凭直觉知道,颜色最鲜艳的生物往往最不适合食用。——这才是 concept 的内容,是concept的同位语。
2. 从句子结构来看,同位语之间的关系比定语密切,同位语一般不能被定语成分分隔。
