    When author Nicholas Carr began researching his book on whether the Internet is ruining our minds, he restricted his online access and e-mail. His new book argues the latest technology renders us less capable of deep thinking. Carr found himself so distracted (分心的) that he couldn’t work on the book while staying as connected. After first feeling confused by his sudden lack of online connection, he was able to stay focused on one task for a long period within several weeks.

Reading on the Internet has changed how we use our brains. Facing much text, video, music, links to other web pages and blogs, our minds have become used to skimming and scanning information. As a result, we have developed sharper skills at making fast decision, particularly visual ones, Carr wrote.

But now most of us seldom read books, long articles that would help us focus. We are becoming more like librarians than scholars who digest and interpret information. That lack of focus hinders (妨碍)our long-term memory, leading many of us to feel distracted, he wrote.

“What we are losing is a whole other set of mental skills, the ones that require not the shifting of our focus but the maintaining of our focus,” Carr said, adding that for centuries books shielded (保护)our brains from distraction, focusing our minds on one topic at a time.

But with devices such as Apple’s iPad becoming common, Carr predicts books too will change. “New forms of reading always require new forms of writing,” he wrote. Carr has a suggestion for those who feel web surfing has left them incapable of concentration — slow down, turn off the Internet and practice the skills of contemplation (思考)and reflection. “It is pretty clear from the brain science that if you are constantly distracted, you are not going to think in the same way that you would think if you paid attention.”
