雨落风残

??  uncertainty is keeping foreign investments away and leading  to the hoarding of key commodites at home. ?? put the chances of a peaceful trasition at risk.我只能听到这个程度了，也许对美式英语口语的特点还不了解，我差点听吐血。

雨落风残

General uncertainty is kept foreign investment at bay 这里好像不符合语法啊！ 可以说 is keeping,has kept 或者是kept，这里is kept如何解释？
