I've always been an optimist and I suppose that is rooted in my belief that the power of creativity and intelligence can make the world a better place.
For as long as I can remember, I've loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old Teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.
When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of "a computer on every desk and in every home," which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have. And after 30 years, I'm still as inspired by computers as I was back in seventh grade. I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness--to help us solve problems that even the smartest people couldn't solve on their own.
Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it "tap-dance to work." My job at Microsoft is as challenging as ever, but what makes me "tap-dance to work" is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetime's worth of photos, and they say, "I didn't know you could do that with a PC!"
But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world. There are still far too many people in the world whose basic needs go unmet.
I believe that my own good fortune brings with it a responsibility to give back to the world. My wife, Melinda, and I have committed to improving health and education in a way that can help as may people as possible.
As a father, I believe that the death of a child in Africa is no less poignant (辛酸的) or tragic than the death of a child anywhere else. And that it doesn't take much to make an immense difference in these children's lives.
I'm still very much an optimist, and I believe that progress on even the world's toughest problems is possible and it's happening every day. We're seeing new drugs for deadly diseases, new diagnostic tools, and new attention paid to the health problems in the developing world.
I'm excited by the possibilities I see for medicine, for education and, of course, for technology. And I believe that through our natural inventiveness, creativity and willingness to solve tough problems, we're going to make some amazing achievements in all these areas in my lifetime.

根据下面内容，回答题：
Many of the problems we face today are not so new as we think they are. And some of our modern solutions are not so new， either. The problem of energy shortages and the solution of using solar energy go back at least to early Greek cultures. The climate in the coastal areas of Greece 2，500 years ago was characterized by cool winters， much as it is today. At that time， the Greeks heated their homes with small， charcoal-burning heaters. In other words， wood （which is used to make charcoal） was their primary source of energy.However， by the fifth century BC fuel shortages had become common because， in many parts of Greece， the firewood in the forests had been depleted. Once the supply of firewood from the local forests ran out， people began to use the wood from olive groves as fuel. But this solution had its own problem. It reduced the olive crop， a valuable resource to the Greeks. By the fourth century BC， the city of Athens banned the use of olive wood for fuel. Wood had to be imported from farther and farther away， making it more difficult to obtain and more expensive to use. About this time the Greeks began to build their houses facing south， so that the low sun in winter could penetrate and help heat the interiors. Excavations of ancient Greek cities suggest that large areas were planned so that individual homes could take maximum advantage of passive solar energy.
