1. 一个人拥有越多的知识，成功的可能性就越高。用英语怎么翻译呢
我的理解：
英语中表达可能性越高，如果用chance或possibility的话，一般不说higher，which sounds a bit like Chinglish stuff。we use BETTER instead.
参考译文：
The more knowlodge one aquires, the better chance one will have of achieving success.
or
The more knowledge one acquires, the more likely one will be to achieve success.
这句话其实不用the more..., the more的句式也可以。
Ex. Expansion of knowledge contributes to the likelihood of success.
