问题 Quasars are so distant that their light have taken billions of years to reach the Earth; consequently, we see them as they were during the formation of the universe.
选项 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
答案 A
解析 本句大意：类星体那样的遥远以至于它们的光需要几十亿年才能到达地球，因此，我们看到类星体的样子就是它们在宇宙形成时的样子。as if, as though之后一般跟从句，而不跟介词短语；同时它们含有“与事实相反之意”，C、E改变了句意因而是错的。B中从句中的过去完成时是没有根据的，D中句子的强调主体we变成了they，同时did替代前面的appear tous，导致句意违背客观事实，因为宇宙形成时并没有人类存在。
