这里想问一下关于C答案的called的修饰对象，这种用分词修饰的方法如果是ing形式的话是可以修饰整个句子，作为伴随状语的。但是ed形式的好像不可以这样的什么？called是不是需要就近修饰opening的还是可以跳跃去修饰前面的poking？按照逻辑上是应该修饰poking的，语法上可以这样子做么？也就是说这类ed形式的修饰是必须要就近的还是可以跳跃的？

还有就是called和located修饰的是同一个东西么？

修饰 projections

是修饰同一个

called从逻辑上是修饰opening,因为pore和opening 的意思都是小孔,从逻辑上是成立的

poking是分词作为projections的修饰成分啊

which has fingerlike projections
        poking through the opening, called the taste pore, located at the top of taste bud

红色是主要成分,绿色修饰projections,兰色修饰opening,黄色修饰pore
