It was supposed to be an informal talk, but he spoke rather didactically. 这本应是次非正式的谈话,可他来了番说教。
To return to Franklin, this didactically waggish man blandly assured English readers that it was grand to see the whales leap like salmon up the falls of Niagara. 再回过来说好训人,喜谐谑的富兰克林,可不动声色地使欧洲人相信鲸鱼象鲑鱼那样跳过尼亚加拉瀑布,真可谓蔚为大观。
I don't say didactically that experience can only be gained firsthand. 我不想以教训的方式说经验只能直接获得。
