(6) 大抵世上无难为的事，只胡乱做将去，自有水到渠成日子。如子髯之才，天下事何不可为?

　　All in all, nothing in this world is that hard to do -- just charge ahead and do it! A day will inevitably come when "the ditch will be dug and the waters flow through." For a man with talent like yours, there is nothing in the world that is impossible.

　　(袁宏道《致李子髯》，Jonathan Chaves译)

　　该例“天下事何不可为?”也是以否定反问表达“天下事无不可为”的肯定结论。译文舍弃了疑问句形式，代之以双重否定there is nothing ... impossible的陈述句式，主要是出于构句的考虑。语义方面两者区别不大，但就表情功能而言，陈述句的效果不及疑问句。
