　　As IBM begins its second century, the American technology pany 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 *** all 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 *** art phone, but doesn't have access to a power grid which is a very mon thing, and literally in a shoe has something that recovers energy from walking and can charge the battery to enable that person to actually bee 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.'"

　　就在美国国际商用机器公司进入其第二个世纪时，这家美国技术公司公布了它的第六个五五计划，一份关于5项创新技术的清单，公司预期将在五年之内实现这些创新技术。 其中的一个会帮助我们产生少量能量来补充家用电能。 伯尼•麦叶森是IBM公司创新部的副总经理，他说：“你可以用微电子产能。比如，第三世界的一个人，他有电话或者是智慧手机，但是却没电了，这是个很常见的事情。而你可以给他一双鞋子，可以通过走路就能产生能量并且可以充电，从而使那个人继续和外界保持联络。” 另一个创新会使那些难记的密码过时。很快，我们就会利用名为生物测定学的技术来进入邮箱或者银行账户。 “想象一下，事物能够辨别出你，当你走到取款机前，它看你一眼然后就说‘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.

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 pleted its first SARS virus genome sequencing, SARS is now the world’s largest recognized the dangers of the disease, but why not other countries pleted first, and we just pleted 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.

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 *** ysis is that we rely on our mon 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 acpanied 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 bee knowledge Explorers, let us unknown roaming on the road, let me use our creativity to the world we live a better place.
