As IBM begins its second century, the American technology company is releasing its sixth annual Five-in-Five, that's a list of five innovations the firm expects will see within five years. One of them will enable us to generate small amounts of energy to supplement the electric power we use in our homes. "You can do micro-electronic generation." Bernie Meyerson is vice president of Innovation at IBM. "For instance, you can have somebody in the third world who has access to a phone or a smart phone, but doesn't have access to a power grid which is a very common thing, and literally in a shoe has something that recovers energy from walking and can charge the battery to enable that person to actually become connected with the rest of the world." Another innovation will make those hard-to-remember passwords obsolete. Soon, in order to access our e-mail or bank account, we'll use a technology known as biometrics. "Imagine that things recognize you, you walk up to an ATM, it takes one look says, 'Yep, you're you.'"
就在美國國際商用機器公司進入其第二個世紀時，這家美國技術公司公佈了它的第六個五五計劃，一份關於5項創新技術的清單，公司預期將在五年之內實現這些創新技術。 其中的一個會幫助我們產生少量能量來補充家用電能。 伯尼•麥葉森是IBM公司創新部的副總經理，他說：“你可以用微電子產能。比如，第三世界的一個人，他有電話或者是智能手機，但是卻沒電了，這是個很常見的事情。而你可以給他一雙鞋子，可以通過走路就能產生能量並且可以充電，從而使那個人繼續和外界保持聯繫。” 另一個創新會使那些難記的密碼過時。很快，我們就會利用名爲生物測定學的技術來進入郵箱或者銀行賬戶。 “想象一下，事物能夠辨別出你，當你走到取款機前，它看你一眼然後就說‘是的，是你本人。’”

The presence of students, ladies and teachers, everyone! I was prepared intervals of cloud today, in honor here entitled "Technology and Future" speech, I am very proud of both, but some unease. In recent years, we have seen our great motherland, the cause of the rapid development of technology, which allow me to a Chinese I feel very proud. Remember that long ago, cell phone use almost the only one, which is called, but a few years ago, cell phones has undergone great changes, not only look more beautiful, but also use more, you can use the phones to take pictures, meetings, Internet, text messages, etc. a series of things that I their life more convenient, so I am more aware of the strength of the technology, but I am just a Fledglings students, "technology" as the word also aware of the limited, I am unable to use some very difficult theory to elaborate technology Xuanji, no right to work on their elders I can promise of the technology blueprint. But I am willing to use a student’s perspective to the Imagine technology and the future.
From genetic engineering "is a live Princes" dream, nano-technology "- not washing your clothing," promises; From artificial intelligence "will give you a cute robot dog" warm, transgenic technology "let people grow mouse ears" Wonders. The new technology in the birth of a new technology that will let people wild with joy, because these new technologies is gradually improving our lives, let us learn more about ourselves. In the near term, China completed its first SARS virus genome sequencing, SARS is now the world’s largest recognized the dangers of the disease, but why not other countries completed first, and we just completed the countries? Very simple, this illustrates that our country backward than others, worse than others, we look at the past, had just started a country’s reform and opening up to the current level of science and technology has lead a large country, our motherland experienced a number of ups and downs, how many difficulties and bumpy However, we still back all of the motherland, the motherland because we firmly believe that - not only technological change destiny, can change the future.
For our generation, the general feeling of the community is a strong sense of competition, learning a foot down. Science knowledge is the focus of our attention, Albert Einstein, and Stephen Hawking, Bill Gates is the star we have in mind, computer science, physics and chemistry of modern dynamic is constantly affect us. We have to understand the importance of technology, know that the technology universal.
Although technology to create a new life prospects soliciting thoughts, inspiring. However, the final analysis is that we rely on our common efforts to realize. , As the future construction of the backbone of our generation of young people shoulders the burden is not light, new opportunities are always accompanied risks and challenges, but we will not give up that easily, we use our youth to predecessors vowed: never live up to their predecessors of our hope.
Looking back at the history of civilization, Anderson is the history of mankind against the darkness of ignorance, is the scientific lit a fire in the raging human soul of hope; Technology Support civilization, science and technology to create the future, but the future is in our hands. Let us become knowledge Explorers, let us unknown roaming on the road, let me use our creativity to the world we live a better place.
