You’ll need the knowledge and problem-solving skills you learn in science and math to cure diseases like cancer and AIDS, and to develop new energy technologies and protect our environment. You’ll need the insights and critical-thinking skills you gain in history and social studies to fight poverty and homelessness, crime and discrimination, and make our nation more fair and more free. You’ll need the creativity and ingenuity you develop in all your classes to build new companies that will create new jobs and boost our economy.

你们将需要利用你们通过自然科学和数学课程所学到的知识和解决问题的能力来治愈癌症、艾滋病及其他疾病，开发新的能源技术和保护我们的环境。你们将需要利用你们在历史学和社会学课堂上所获得的知识和独立思考能力来抗击贫困和解决无家可归问题，打击犯罪和消除歧视，使我们的国家更公平、更自由。你们将需要利用你们在所有课堂上培养的创造力和智慧来创办新公司，增加就业机会，振兴我们的经济。

We need every single one of you to develop your talents and your skills and your intellect so you can help us old folks solve our most difficult problems. If you don’t do that -- if you quit on school -- you’re not just quitting on yourself, you’re quitting on your country.

我们需要你们每个人发挥你们的聪明才智和技能，以便帮助老一辈人解决我们面临的最棘手问题。如果你们不这样做，如果你们辍学，你们不仅仅是自暴自弃，也是抛弃自己的国家。

Now, I know it’s not always easy to do well in school. I know a lot of you have challenges in your lives right now that can make it hard to focus on your schoolwork.

我自然知道要做到学业优秀并非总是易事。我知道你们许多人在生活中面临挑战，难以集中精力从事学业。

I get it. I know what it’s like. My father left my family when I was two years old, and I was raised by a single mom who had to work and who struggled at times to pay the bills and wasn’t always able to give us the things that other kids had. There were times when I missed having a father in my life. There were times when I was lonely and I felt like I didn’t fit in.

我明白这一点。 我有亲身感受。两岁时，我父亲离家而去，我是由一位单亲母亲抚养成人的，母亲不得不工作，并时常为支付生活费用而苦苦挣扎，但有时仍无法为我们提供其他孩子享有的东西。有时，我渴望生活中能有一位父亲。有时我感到孤独，感到自己不适应社会。

So I wasn’t always as focused as I should have been on school, and I did some things I’m not proud of, and I got in more trouble than I should have. And my life could have easily taken a turn for the worse.

我并非总是像我应该做到的那样专心学习，我也曾做过我如今不能引以为豪的一些事情，我曾惹过不应该惹的麻烦。我的人生原本会轻易陷入更糟糕的境地。

But I was -- I was lucky. I got a lot of second chances, and I had the opportunity to go to college and law school and follow my dreams. My wife, our First Lady Michelle Obama, she has a similar story. Neither of her parents had gone to college, and they didn’t have a lot of money. But they worked hard, and she worked hard, so that she could go to the best schools in this country.

但是，我当年际遇不错。我有过许多第二次机会，我有幸能上大学，上法学院，追求自己的理想。我的妻子，我们的第一夫人米歇尔•奥巴马，也有着类似的经历。她的父母都未曾上过大学，家里很穷。但他们非常勤奋 ，她也是如此，因此她得以进入一些美国最好的学校。
