英语翻译原句：我否认了他们所说的；但现在到头来还是我,噢,多么荒唐,必须承认曾被我称作“流言蜚语”的,是事实.我的翻译:

你的译文总的来说还可以,但应注意即使是直译也宜把中文原句做适当调整,便于英文的流畅得体.不妨把"多么荒唐"拿到前面.repudiate一词在此有大词小用之嫌,用deny即可.
I denied what they said;Oh,but badly ridiculous eventuality turns up:It is also me who concede that things I've ever called "rumours" turn out true.
concede可以被 have to admit代替
