[奥巴马]顺便说一句，这在美国是非常常见的传统--举行这种市政会议，我现在要做的就是如果你有兴趣提问的话请举手，我会说请你提问。我会从在座的观众中问一个问题，然后再让这些学生代表以及洪大使从网上代为提问。我先找个男生再找一个女生，来回这么找，让大家知道我是公平的。

PRESIDENT OBAMA: So -- I just want to make sure this works. This is a tradition, by the way, that is very common in the United States at these town hall meetings. And what we're going to do is I will just -- if you are interested in asking a question, you can raise your hands. I will call on you. And then I will alternate between a question from the audience and an Internet question from one of the students who prepared the questions, as well as I think Ambassador Huntsman may have a question that we were able to obtain from the Web site of our embassy.

[奥巴马]我先找个男生再找一个女生，来回这么找，让大家知道我是公平的。这位小女孩你来开始吧。请等一下我给你话筒。

PRESIDENT OBAMA: So let me begin, though, by seeing -- and then what I'll do is I'll call on a boy and then a girl and then -- so we'll go back and forth, so that you know it's fair. All right? So I'll start with this young lady right in the front. Why don't we wait for this microphone so everyone can hear you. And what's your name?

[现场提问]我叫程熙，我是复旦大学的学生，上海和芝加哥从1985年开始就是姐妹城市，这两个城市进行过各种经贸、文化、政治交流，你现在在采取什么措施来加深美国和中国城市之间的关系。世博会明年将在上海举行，你是否准备参加世博会呢？

Q   My name is (inaudible) and I am a student from Fudan University. Shanghai and Chicago have been sister cities since 1985, and these two cities have conduct a wide range of economic, political, and cultural exchanges. So what measures will you take to deepen this close relationship between cities of the United States and China? And Shanghai will hold the World Exposition next year. Will you bring your family to visit the Expo? Thank you.

[奥巴马]非常感谢你的问题，我在来之前和上海的市长共进午餐，他和我说他跟芝加哥，也就是我的家乡有着很好的关系，他两度访问芝加哥，我认为城市间有这种交流非常非常好。

Well, thank you very much for the question. I was just having lunch before I came here with the Mayor of Shanghai, and he told me that he has had an excellent relationship with the city of Chicago -- my home town -- that he's visited there twice. And I think it's wonderful to have these exchanges between cities.

[奥巴马]我刚才和韩市长谈的问题之一就是我们这些城市如何可以彼此进行交流，比如就洁净能源的策略进行交流。因为美中两国共同面对的问题就是我们如何在人口增长的过程中，又解决气候变化的问题，同时减少我们二氧化碳的排放。很显然，在美国以及在很多发达国家，人均能耗量都比中国的人均能耗量大，不过在中国成长的过程中，能耗量会增加，因此，我们找到新的战略，这符合我们两国的利益。

PRESIDENT OBAMA:  One of the things that I discussed with the Mayor is how both cities can learn from each other on strategies around clean energy, because one of the issues that ties China and America together is how, with an expanding population and a concern for climate change, that we're able to reduce our carbon footprint. And obviously in the United States and many developed countries, per capita, per individual, they are already using much more energy than each individual here in China. But as China grows and expands, it's going to be using more energy as well. So both countries have a great interest in finding new strategies.

我们刚才谈了大众捷运，我知道上海和其他城市之间就有这种快轨。我相信美国以及芝加哥可以在这种快轨方面向中国学习。

We talked about mass transit and the excellent rail lines that are being developed in Shanghai. I think we can learn in Chicago and the United States some of the fine work that's being done on high-speed rail.

而在美国我们也在学习如何建造这种绿色建筑，当然，在上海我看到有很多的吊车，很多的建筑在盖起来。因此在这些新的技术上我们进行合作是非常非常重要的，使得我们每一个建筑在采光、取暖等等方面都能减少能耗，使能源效率更高，这方面是我们两国可以相互学习的。

In the United States, I think we are learning how to develop buildings that use much less energy, that are much more energy-efficient. And I know that with Shanghai, as I traveled and I saw all the cranes and all the new buildings that are going up, it's very important for us to start incorporating these new technologies so that each building is energy-efficient when it comes to lighting, when it comes to heating. And so it's a terrific opportunity I think for us to learn from each other.

我知道上海世博会的焦点之一就是提高能效的问题，刚才韩市长跟我讲了这个问题，我将非常乐于参加上海世博会，当然，我现在不知道那时候我的时间安排怎么样，不过我感到非常高兴上海世博会将有我们的美国馆，我们知道现在参观世博会的人会有七千万人。

I know this is going to be a major focus of the Shanghai World Expo, is the issue of clean energy, as I learned from the Mayor. And so I would love to attend. I'm not sure yet what my schedule is going to be, but I'm very pleased that we're going to have an excellent U.S. pavilion at the Expo, and I understand that we expect as many as 70 million visitors here. So it's going to be very crowded and it's going to be very exciting.

芝加哥已经举办过两次世博会，这两次世博会都给我们芝加哥带来了巨大的好处，我希望上海情况也是如此，谢谢。

Chicago has had two world expos in its history, and both of those expos ended up being tremendous boosts for the city. So I'm sure the same thing will happen here in Shanghai.Thank you. (Applause.)
