73. Combning enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could put in their path, but their relatively sudden disappearance during the Pa;eolithic era indicates that an inabilityto dapt to some environmental change led to their extinction. a, appear as equipped for facing any obstacle the environment could put in their path b, appear to have been equipped to face any obstacle the environment could put in their path c, appear as equipped to face any obstacle the environment could put in their pahts d, appeared as equipped to face any obstacle the environment could put in their paths e, appeared to have been equipped for facing any obstacle the environment could put in their path. 答案B 请问，为什么equipped不能表达过去，而为什么have been equipped就表达了过去式呢。还有，能不能帮我解释一下这句话
Because Neanderthals “disappeared,” the verb describing their apparent abilities cannot be present tense, so as equipped must be changed to to have been equipped. OG这句解释直译：因为N “disappeared,” 描述他们显著能力的动词不能用现在时态，所以equipped 一定要改成have been equipped。 我晕的是have been equipped不正是现在时态么？equipped不正是过去时态么？ 怎么让OG解释弄的更混了。 请NN帮忙解释。 想楼主也是这个问题。
同问！ OG上找到一句写现在完成时的话：Present perfect: Used with has or have, the present perfect tense describes an action that occurred at an indefinite time in the past or that began in the past and continues into the present. 不知道可不可以理解为，现在完成时即一种发生在过去一个不确定的时间段，或者发生在过去并且延续到现在对现在有影响的行为。
