B．considered to have discovered
C．considering having invented
D．considered to have invented
答案
答案：D
本题考查consider的用法，be considered to have done意为“被认为已经干了……”合乎题意。
(1)consider作“考虑”讲时可用consider+n./pron. doing结构。
(2)consider作“认为”讲时不可用consider doing 结构。
(3)consider sb./sth.(to be)+n./adj.认为某人/物怎样，该复合结构中to be 可省略。
(4)be considered to have done认为某人已经干了某事。
