好想法 可以另寻专业途径修改嘛

改这个 跟自己翻译差不多啊！

我一句一句帮你改吧。
第一句完全是个病句，一个句子没有连词却有两个谓语（is和become），而as引导的状语从句却又缺了个谓语。楼主英语基本功得好好改进下，剩下的我抽空一句一句给你慢慢改吧。（小弟也就只能上班闲的时候给帮忙哦，万物见怪！）
Financeis the core of modern economy, as economic globalization and financialliberalization, security and stability of financial markets become our focus.

改：
Finance is now the core of modern economy and as economic gloalization and financial liberalization developed, the issue of security and stability has become the financial market's highlight.

Aslong as there are financial activities,financial risks will inevitablely ariseand develope. Risks in the financial market are not isolated from one andanother.Due to the fact that financial markets and financial organizations areall highly and closely related as well as interactive with each other,so whenthe risk hits,it will expand and diffuse if it got accumulated and not handledappropriately,and this will lead to the deterioration the situation of otherfinancial entities.

这堆话显得又啰嗦又杂乱无章。。

改：
Where there are financial activities, there are financial risks. The risks, which are not independent to each other for the highly correlation among financial institutions and financial market, would hit the market, expand and diffuse if not handled appropriately,  leading to a bubble and the deterioration of financial subjects.
