But let’s be clear, studying abroad is about so much more than improving your own future. It’s also about shaping the future of your countries and of the world we all share. Because when it comes to the defining challenges of our time -– whether it’s climate change or economic opportunity or the spread of nuclear weapons -- these are shared challenges. And no one country can confront them alone. The only way forward is together.

　　我想要说的是，出国留学绝不仅是改善你们自己的未来，它也关乎塑造你们的国家、关乎我们共有的世界的未来。因为我们这个时代的决定性挑战一一无论是气侯变化、经济机遇，还是核武器扩散一一这些都是我们共同的挑战。没有任何一个国家能够单独应对它们……唯一的出路就是共同携手。

　　That’s why it is so important for young people like you to live and study in each other’s countries, because that’s how you develop that habit of cooperation. You do it by immersing yourself in one another’s culture, by learning each other’s stories, by getting past the stereotypes and misconceptions that too often divide us.

　　这就是为什么年轻人到彼此国家学习和生活是如此重要。因为这是你们培养合作习惯的途径一一你们通过融入不同的文化，通过了解彼此的故事，通过跨越常常隔膜我们的成见和误解，来做到这一点。

　　That’s how you come to understand how much we all share. That’s how you realize that we all have a stake in each other’s success -- that cures discovered here in Beijing could save lives in America, that clean energy technologies from Silicon Valley in California could improve the environment here in China, that the architecture of an ancient temple in Xi’an could inspire the design of new buildings in Dallas or Detroit.

　　这是你们了解到我们共享多少东西的途径。这是你们认识到我们的成功惠及彼此的途径。在北京发现的治序方法可以挽救在美国的生命，来自加州硅谷的清洁能源技术可以改善中国的环境，西安一座古老寺庙的架构可激发达拉斯或者底特律新建筑设计的灵感。
