"Mirror Worlds" is only one of David Gelernter’s big ideas. Another is "lifestreams"—in essence, vast electronic diaries. "Every document you create and every document other people send you is stored in your lifestream," he wrote in the mid-1990s together with Eric Freeman, who produced a doctoral thesis on the topic. Putting electronic documents in chronological order, they said, would make it easier for people to manage all their digital output and experiences.
Lifestreams have not yet replaced the desktop on personal computers, as Mr. Gelernter had hoped. Indeed, a software start-up to implement the idea folded in 2004. But today something quite similar can be found all over the web in many different forms. Blogs are essentially electronic diaries. Personal newsfeeds are at the heart of Facebook and other social networks. A torrent of short text messages appears on Twitter.
Certain individuals are going even further than Mr. Gelernter expected. Some are digitising their entire office, including pictures, bills and correspondence. Others record their whole life. Gordon Bell, a researcher at Microsoft, puts everything he has accumulated, written, photographed and presented in his "local cyberspace". Yet others "log" every aspect of their lives with wearable cameras.
The latest trend is "life-tracking". Practitioners keep meticulous digital records of things they do; how much coffee they drink, how much work they do each day, what books they are reading, and so on. Much of this is done manually by putting the data into a PC or, increasingly, a smartphone. But people are also using sensors, mainly to keep track of their vital signs, for instance to see how well they sleep or how fast they run.
The first self-trackers were mostly geeks fascinated by numbers. But the more recent converts simply want to learn more about themselves, says Gary Wolf, a technology writer and co-founder of a blog called " The Quantified Self". They want to use technology to help them identify factors that make them depressed, keep them from sleeping or affect their cognitive performance. One self-tracker learned, for instance, that eating a lot of butter allowed him to solve arithmetic problems faster.
A market for self-tracking devices is already emerging. Fitbit and Greengoose, two start-ups, are selling wireless accelerometers that can track a user’s physical activity. Zeo, another start-up, has developed an alarm clock that comes with a headband to measure people’s brainwave activity at night and chart their sleep on the web.
As people create more such self-tracking data, firms will start to mine them and offer services based on the result. Xobni, for example, analyses people’s inboxes (" xobni" spelled backwards) to help them manage their e-mail and contacts. It lists them according to the intensity of the electronic relationship rather than in alphabetical order. Users are sometimes surprised by the results, says Jeff Bonforte, the firm’s boss: "They think it’s creepy when we list other people before their girlfriend or wife.
Which of the following statements is TRUE of electronic documents?
选项
A、They are open to the individual’s friends.
B、The types of documents are limited.
C、They can be put in various websites.
D、They are mainly presented in pictures.
答案
C
解析
细节题。第二段第三句指出“But today something quite similar can be found all over the web inmany different forms.”,接着举例说明Blogs,Facebook,Twitter等不同网站的情况,由此可知C符合文意,故为答案。
