73. Combining 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 Paleolithic era indicates that an inability to adapt
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 paths,
(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,

答案选B. 并且说了一句特别蛋疼的话：Because Neanderthals “disappeared,” the verb describing their apparent abilities cannot be present tense, so "as equipped" must be changed to "to have been equipped". 为什么不用appeared？？？？？还有现在完成时不是表示动作一直持续到现在或者对现在有影响？

75. A proposal has been made to trim the horns from
rhinoceroses to discourage poachers; the question is
whether tourists will continue to visit game parks and
see rhinoceroses after their horns are trimmed.
(A) whether tourists will continue to visit game
parks and see rhinoceroses after their horns are
(B) whether tourists will continue to visit game
parks to see one once their horns are
(C) whether tourists will continue to visit game
parks to see rhinoceroses once the animals’
horns have been
(D) if tourists will continue to visit game parks and
see rhinoceroses once the animals’ horns are
(E) if tourists will continue to visit game parks to
see one after the animals’ horns have been

答案是C. OG解释说“Th e verb following after should be the present-perfect have been trimmed to reflect that the trimming must occur before the tourists arrive.” 为什么用 "are”不行而一定要用 have been 呢？

谢谢大家

75,因为A B后面their指代不清

73题中 apppear 和后面的 indicates 都表明是现代人对其的一种推测。

75中用have done 的原因是为了表示过去动作对现在情况有影响，即trimmed horns 对tourists来不来公园有影响。are没有这种意思。所以相对起来，have done就要比直接用are要好，就单单从逻辑意义上来讲哈~个人愚见欢迎讨论！
