OG12-73 求版主帮帮忙 - ChaseDream

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

答案B

1. appear as equipped, appear-ed as equipped, & appear to have been equipped这三个phrase意思上有什么区别啊？OG里说有的imply现在仍然这么穿，有的讲以前这么穿，。。。，不是非常清晰。
2. OG答案说之所以用appear是为了与后边indicates平行，另外也表示这是current evidence about Neanderthals in the past。我对这个“current evidence”有点疑惑，麻烦您帮我elaborate一下。。要是我用appeared 和 indicated也正确吧？其实我觉得用过去式最好！！
3. 另外我觉得其实即便时态不一样（i.e., appeared & indicate），也是可以parallel的啊（只要逻辑上同就行啊。。）版主觉得呢？

appear和indicate都是现在时啊，只是一个是neanderthals是复数，一个eolithic era是单数而已啊

至于appear as equipped, appear-ed as equipped, & appear to have been equipped应该是靠理解意思吧……我也不太懂

如果是appear as，一定是说显现出某一个形态，而现在Neanderthals已经消失了，不能再显现某个形态了，只能是我们从现代的视角去远古的Neanderthals，所以appear用现在时，此时是表达seem的意思(看起来似乎)。不定式用完成时，是表达“过去的事情”。

appear和indicate都是从现在的视角去看，所以应该时态上平行。现在的视角看到的东西就是current evidence。

版主，我还想问，像appear to, seem to这样的词组是不是也可以有过去时呢？（比如加上明显的过去时间做状语）google一下有很多啊？什么情况下用过去时呢？

我还想问，像appear to, seem to这样的词组是不是也可以有过去时呢？（比如加上明显的过去时间做状语）google一下有很多啊？什么情况下用过去时呢？

这应该是纯粹的一般过去时态，从过去的视角来看就是appeared to，比如某个事件在过去看来是怎么怎么样的，通常用appeared to暗含了现在看起来已经不再那样了的含义.

OG上对C的解释是while individual N may well have followed different paths, this sentence is about the single evolutionary path taken by N as a species.

不太理解关于他说的taken by N as a species。麻烦帮我解释一下`~谢谢了

taken by N修饰path，其中taken是被动语态的缩略(path that is taken by N as a species).

by default, "appear" is in the present tense, since we're talking about the way these things appear to present-day observers.

if there were a context that would place "appear" in the past, then you could use the past tense. for instance: to nineteenth-century observers, they appeared to have been equipped...
but, absent such a context, you should go with the present, for simplicity (the default assumption is that this "appears" to be the case to present observers).

--

in this case, you've also got parallelism between "appear" and "indicates", two descriptions that both describe observations made in the present.
since "indicates" is not underlined, that determines the tense context. so your other observation, which is made at the same time, should be parallel to it.

明白了很多，不过还有个问题不解：
发现选项中appear as后面都跟equipped，而appear to后面都是have been equipped
后者明显是被动语态，而者看起来像个分词。但从A的解释中As equipped indicates that Neanderthals still appear this way;可知appear as equipped是现在时被动。正确答案应表达为过去时+被动。所以我觉得应该是had been equipped，或者was equipped（当然从后面的could、let都是过去式看这里用过去完成应该更好）可为什么答案用的是现在完成时呢？

Longman对appear to do sth 的解释

used to say how something seems, especially from what you know about it or from what you can see
appear to be sth

　appear to do sth
　The survey appears to contradict motor industry claims.

Longman对appear as没有解释，可以看dict.cn的解释如下：
appear as
v. 作为 ... 出现, 表现为
Examples:
He was billed to appear as Macbeth.
节目单上注明他将登台饰演马克白。
An apparition of a living person that appears as a portent just before that person's death.
灵魂出窍，亡魂显现活着的人在其临死前出现的作为预兆的鬼魂
He is billed to (ie It is announced that he will) appear as Othello.
已把他列入节目单内，将扮演奥赛罗。

Appear on the stage as
登台扮演
At least 至少起码; In spite of 不管尽管虽然; Appear on the stage as 登台扮演; englishlxq.ucoz.com
appear as hosts at the show
作为主持人出现在演出中

所以appear as 大部分都是用在演出，扮演某种角色，以某种形式或者身份出现的意思。这与appear to do的看起来呈某种状态明显有区别，而原文应该用appear to do
