《朗文当代高级英语辞典》第5版 best 词条名词用法有如下内容：13. be for the best especially spoken used to say that a particular even may seem bad now, but might have a good result later【尤口】也许不是件坏事：I still don't want him to go, but maybe it's for the best. 我还是不希望他去，但这也许是件好事。

    在网友的句子中，for the best 就是这种用法。

    I was rejected by one college, but I really like where I am now, so I guess things worked out for the best.这里的things worked out for the best是宾语从句，作guess的宾语。things指I was rejected by one college这件事，所以最好改为 the thing ；这里的 worked out = turned out (结果是)。

    【试译】我曾经被一所大学拒绝了，但我确实很喜欢我现在的样子，所以我猜想这也许是件好事。
