    Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli , “it has to be so much better that it replaces what we have already.” The Internet is one example --what will be the next?

       子列子穷，容貌有饥色。客有言于郑子阳者^①曰：“子列子御寇，盖有道之士也。居君之国而穷，君乃为不好士乎？”子阳令官遗之粟数十秉^②，子列子出见使者，再拜而辞。使者去，子列子入，其妻望而拊^③心曰：“闻为有道者，妻子皆佚乐^④。今妻皆有饥色矣，君过而遗先生食，先生又辞，岂非命哉！”子列子笑而谓之曰：“君非自知我者也，以人之言而知我，以人之言以遗我粟也，其罪我也，又将以人之言，此吾所以不受也。且受人之养，不死其难，不义也；死其难，是死无道之人，岂义哉！”其后，民果作难，杀子阳。
