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

我觉得b、c、e的排除是比较明显的，但是 a\d，我不知道他们的区别在哪？为什么d不对。

1.请问,E怎么排除的?

2.D E的they appear比前面的we see them读起来舒服多了,they did in也比they were during清晰得多
