have been done的一道语法题（尼德兰人题）

Joshuaxuan

Combining enormous physical strength with higherintelligence, the Neanderthals appear as equipped for facing any obstaclethe environment could put in their path, but their relatively suddendisappearance during the Paleolithic era indicates that an inability to adaptto some environmental change led to their extinction.

A. appear as equipped for facing any obstacle theenvironment could put in their path,

B. appear to have been equipped to face anyobstacle the environment could put in their path,

C. appear as equipped to face any obstacle theenvironment could put in their paths,

D. appeared as equipped to face any obstacle theenvironment could put in their paths,

E. appeared to have been equipped for facing anyobstacle the environment could put in their path,

OA：B

想请问一下B中，have been equipped为什么要用被动语态? 为何是尼德兰人被equipped？我总觉得应该是appear to have equipped看到这个被动直接就把B排除了，求大神解惑谢谢┭┮﹏┭┮

看到了好多地方说”主动语态优先“这种说法，我觉得还是不能一句话这么简单的概括了，被动语态有被动语态的应用场合；如果知道动作的发出者，也知道动作的接受者，肯定是主动语态优先于被动语态；但是在压根不知道动作的发出者的时候，就不能避免的要用被动语态了；这里你总不能说Neanderthal equip themselves吧，好别扭。

还是以最总的表达结果为主。

appear to have done sth这种结构在好多题目里面都出现过，btw

【如果知道动作的发出者，也知道动作的接受者，肯定是主动语态优先于被动语态；但是在压根不知道动作的发出者的时候，就不能避免的要用被动语态了】

这句话收下了，感谢老哥，帮助很大~！！
