标题: 关于as的用法一问
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 correct answer is A.

请教答案中as的用法。按照我之前的理解,as应该是平行结构,也就是说as后面的这个句子应该和主句意思相似。如I don't ski as  often as he (does).或者 He plays piano as well as Sally (does).
但是这里的as到底做何解?还是一种特殊用法?
