问题     Do you want to live forever? By the year 2050, you might actually get your wish — providing you are willing to leave your biological body and take up residence in silicon circuits. But long before then, perhaps as early as 2005, less radical measures will begin offering as semblance(相似)of immortality(长生不老).
    Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, plus all that you say and write, can be recorded, analyzed and automatically indexed, and added to your personal chronicles(编年史). By the 2030s, it may be possible to capture your nervous system’s electrical activities, which would also preserve your thoughts and emotions. Researchers at the Laboratories of British Telecommunications have defined this concept as Soul Catcher.
    Small electronic equipment will pave the way for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp(头皮)and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
    At first, the Soul Catcher’s companion system — the Soul Reader — might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand the brain’s internal workings, so reading your thoughts and interpreting your emotions might not be possible. But these signals could be conserved for the day when they can be transferred to silicon circuits to rejuvenate minds as everlasting entities. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.
    For people who chose not to live in silicon, virtual immortality could still ease the sense of futility that now haunts many people. Individuals would know their lives would not be forgotten, but would be preserved as a thread in a multimedia quilt that keeps a permanent record of the human race. And future generations would have a much fuller understanding of the past. History would not be dominated by just the rich and powerful, Hollywood stars, and a few elite thinkers.
The main idea of this passage is that______.
选项 A、human beings long for an immortal life
B、there are many difficulties in making the Soul Catcher
C、people can live immortally as technology develops
D、the invention of Soul Catcher has great significance
答案C
解析 本题考查文章主旨，而文章开头一般为主旨提出部分，故将本题答案定位于首段。文章首句是个设问句，引出本文的主题，即人类永生，接着对通过科技实现永生进行了详细阐述，并且说明了永生的意义，因此答案为C)。灵魂捕捉器(soul Catcher)是与实现永生相关的一个重要内容，并且尚处于构想阶段，D)的概括不够全面。把握文章主旨大意需要考生留意文中关键性的句子，如首尾句、转折句等。
