180. Quasars are so distant that their light has taken billions of years to reach the Earth; consequently, we see them as they were during the formation of the universe. (A) we see them as they were during (B) we see them as they had been during (C) we see them as if during (D) they appear to us as they did in (E) they appear to us as though in the answer is A 看了og的解释，还是不很清楚，这里为什么要用一般过去时？（they were during）.为什么不可以用现在一般时？ 不能用they appear是否因为这样就荒谬地说：星星自己跑到我们面前来，星星成了动作地发出者？ 多谢多谢！
这与appear是不是不及物动词没有关系。than作连词用来比较时，就是把前后相连的两个句子相同的部分省去，不同的补出，有时加点助动词什么的避免歧义。也就是说，省掉的都是相同的。所以这里they appear to us as they did就等于they appear to us as they did (to us)。如果不是to us，而是to u$, 那就补成：they appear to us as they did to u$。
