We cannot let this moment slip away. We have come too far and accomplished too much.

我们不能够让机会错失，我们期待得太久，奋斗得太长。

24)Now, the journey ahead will not be easy. Some will say we can't do it. That it's too hard. That we're just not up to the task. But for as long as America has existed, it has been the American way to reject "can't-do" claims, and to choose instead to stretch the boundaries of the possible through hard work, determination and a pioneering spirit.

而今，前路并不平坦。有人说，那太难了，不是我们力所能及的，我们不可能梦想成真。但自从美国诞生以来，我们就有一个美国式的对“不可能”说不的方式----通过努力的奋斗，坚定的信念和积极的心态尽全力触摸那叫做可能的界限。

It is this belief, this optimism, that Senator Obama and I share, and that has inspired so many millions of our supporters to make their voices heard.

这种信念，这份乐观，激励了我和Obama；这种信念，这份乐观，激励了百万的你们，让支持的声音响彻太空。

So today, I am standing with Senator Obama to say: Yes we can.

因此今天，我选择和Obama参议员站在一起说：没错，我们能。

Together, we will work. We'll have to work hard to get universal health care. But on the day we live in an America where no child, no man and no woman is without health insurance, we will live in a stronger America. That's why we need to help elect Barack Obama our president.

我们将一道奋斗，我们将全力以赴，以实现各人都可享有的医疗保健。一旦到了美国出现一个没有孩童，没有男人，没有妇女得不到医疗保健的美国的那天，我们就是生活在一个更加强大的美国里。那就是为何，我们必须帮助奥巴马去成为总统。
We'll have to work hard to get back to fiscal responsibility and a strong middle class. But on the day we live in an America whose middle class is thriving and growing again, where all Americans, no matter where they live or where their ancestors came from, can earn a decent living, we will live in a stronger America, and that is why we must elect Barack Obama our president.

我们将全力以赴，重掌财政责任和一个强势的中产阶级。一旦到了美国出现中产阶级再次繁荣成长，不管他们或者他们的祖先来自何方，能得到一个体面收入的那天，我们就是生活在一个更加强大的美国里。那就是为何，我们必须帮助奥巴马去成为总统。

We'll have to work hard to foster the innovation that makes us energy-independent and lift the threat of global warming from our children's future. But on the day we live in an America fueled by renewable energy, we will live in a stronger America. That's why we have to help elect Barack Obama our president.

我们将全力以赴，鼓励创新，以使能源需求独立，并让我们的孩子远离全球变暧的威胁。一旦到了美国使用了可再生能源的那天，我们就是生活在一个更加强大的美国里。那就是为何，我们必须帮助奥巴马去成为总统。
