appear to have been的用法
1.the dinosaurs appear to have been relatively smart
2.the Neanderthals appear to have been equipped to face any obstacle the environment could put in their path
dinosaurs 和 neanderthal(智人)都是过去的事情,为什么要用现在完成时呢?
句2中为什么要用been equipped作被动呢,我觉得equip应该是neanderthal的主动行为

首先 appear to be 是固定用法,显得/好像是/似乎的意思.
此处两句句子是科普知识内容,讲述的是客观的一些科学理论,所以选择一般现在时描述.用appear. 但是恐龙和智能都已灭绝,所以be动词形式采取了have been表完成.
类似的用法给你两个句子方便楼主理
He wants to read the book tomorrow. 他打算明天读这本书.
He wants to have read the book by tomorrow. 他打算明天前就看完书.
此外equipped正在此处是形容词,是准备好的意思 be equipped to do sth 准备好做某事
