早上好！看来大家来到这里都很激动啊。欢迎光临Google I/O开发者大会。今年是我们第四次举办这个大会。

　　We thought we begin by just reminiscencing for a few moments about how much we have accomplished together. You go back to 2008. That was the first year we held Google I/O. Maybe some of you were there at our annual conference. That year our opening keynote focused on client, connectivity and the cloud. While we recognized this industry was going through dramatic change that mobile phones, smart phones and fast web browsers were changing the face of clients. And that the connectivity was about to explode both in its availability as well as its bandwidth, and that would allow us to build cloud-based services that we could hardly have dreamed of a few years ago. All that happened. In 2009, on this staget we rallied the industry with the Chrome team to move the web forward under the banner of HTML5. And today, modern browsers are btter and faster because of the work of this group of people. So thank you. And that who could forget last year? When we focused (people begin to laugh with the appearance of a cute picture on the screen.) That (the picture) was a lot of fun. We want to thank all of you for making android the global phenomenon that it has become.

　　首先让我们来回顾一下这四年来我们取得了哪些成就。回想2008年，我们举办了第一届Google I/O 大会，也许在座有些人当时也参与其中。那年我们演讲的主题是客户端、网络连接和云技术。我们当时已经意识到这个行业正在经历着翻天覆地的变化，移动电话、智能手机和更快的浏览器正在改变着传统客户端的面貌。另外，无论就可应用性还是就网络带宽而言，我们都将进入网络爆炸时代。这些也使得我们可以建立基于云计算的服务，而这一切都是几年前我们根本没法想象的，但它们也确实发生了。2009年，同样在这个舞台上，我们的Chrome团队凭借HTML5推进了网络技术的革新。如今，因为这群人的努力，现代浏览器变得更好更快。谢谢你们。谁能忘了去年呢？当时我们的主题是（这时，大屏幕上出现了一张很可爱的图片）……这张图片真是可爱极了。感谢各位，因为你们让Android风靡全球。
