在OG的第96页有一题
For some time now, _____ has been presumed not to exist: the cynical
conviction that everybody has an angle is considered wisdom.
选项有 (A) rationality; (B) flexibility; (C) diffidence; (D) disinterestedness
(E) insincerity
我了解答案是disinterestedness
但是请问这句的主词是不是"disinterestedness has been...has an angle"呢?
谢谢 :)
