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？
