OG12-73，比较典型的时态问题，哪位帮忙看看
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.

(B) appear to have been equipped to face any obstacle the environment could put in their path,

(D) appeared as equipped to face any obstacle the environment could put in their paths,

两个疑问：
1、appear为什么不用过去时？既然是已经消失的，那么之前他们所显示的一些特点应该用过去时啊
2、equipe为什么要用现在完成被动时，而不是被动时？

另外一题：
55 percent more delay 与 a 55 percent increase in delays，这个区别在哪里呢？

Christianyang

appear to在这里表示似乎的意思
下一题中的delay，与delays是有意思差异的，楼主可以自己查阅自己会比较清楚一些。可根据原意或者逻辑意思来判断究竟是用哪个意思。
