You can find bubbliness in bits of American finance, including the corporate-bond market, and some nasty off-balance-sheet liabilities like student loans and public-sector pensions, but America does not look like a source of imminent trouble.

你可以在美国金融里找到泡沫碎片，包括证券市场，和一些严重的表外负债，像学生贷款和公共部门养老金，但是美国看起来并不会产生迫在眉睫的麻烦。

I was such an optimistic person, but then there was all of these negatives floating around in my mind all the time, that I just didn't have that same bubbliness that is core to my personality.

我是一个非常乐观的人，但是所有这些负面因素一直在我的脑海中萦绕，以至于我没有像我的性格核心那样的活泼。

The resulting bubbliness in the market has made it even tougher to pick out the real innovators from a sea of wannabes, notes Scott Kennedy of the Centre for Strategic and International Studies, a think-tank in Washington.

华盛顿智囊团战略与国际研究中心的斯科特肯尼迪指出，由此产生的市场泡沫使得从众多想创新的人中挑选出真正的创新者变得更加困难。
