    part 1

  COMPUTER companies keep competing to build s maller devices 装置. They are finding new ways to put data 数据 into less space on a memory chip 内存芯片.

  Computers have been made s maller to fit on to the desktop, s maller again to fit on our laps and again to fit into our shirt pockets 口袋.

  Now, Stuart S. P. Parkin, an IBM researcher, is looking into a new idea in an IBM lab. If it proves successful, electronic devices could hold 10 to 100 times the data in the same amount of space.

  That means the iPod that today can hold up to 200 hours of video could store every single TV program broadcast 播放 during a week on 120 channels.

  Parkin thinks he is close to a breakthrough. This could increase the amount of data stored on a chip.

  At present the flash drives 闪存卡 business is growing quickly. They are used in digital cameras, cellphones and PCs. Flash drives with multiple 多个 memory chips store up to 64gigabytes 十亿字节 of data. A single chip is expected to reach about 50 gigabytes in the next five years.

  However, flash memory has a problem. Although it can read data quickly, it is very slow at storing it. That has led the industry on a hunt for new storage technologies.

  Scientists say Parkin’s new computer memory, called "racetrack memory 赛道内存", could begin to replace flash memory in three to five years.

  WHAT are teenagers nowadays crazy about? Popular songs? Harry Porter books? Sports or online games? For me, the answer is history.

  History is a part of my leisure 空闲的 time. Since I was 10, I’ve been reading history books, collecting old maps and visiting museums. I always get excited when people around me talk about history.

  I have learnt a lot from history. It’s helped me deal with 应付 the problems of growing up. History is precious 珍贵的 wealth.

  History helps me become more mature 成熟的. I used to believe that life is simple to understand. Now I know that we shouldn’t make simple judgments 判断. People aren’t "good" or "bad"; things aren’t "true" or "false".

  History has also made me mentally 精神上 stronger. I’m more responsible now. I have learned useful things about myself from studying the rise and fall of kings and queens.

  When I studied Chinese history between 1840 and 1949, I knew I must be a strong person and do my best for China.

  Francis Bacon wrote, "Histories make men wise". I agree with that. If you know history you respect the past are confident about the future. History tells you where you come from, where you are and where you are going. That is the charm of history. Don’t you think so?
