We’re fortunate to have access to the dynamic network technology, which provides rich resources for learning, connecting and entertaining ourselves.
These distractions are more than mere annoyances.
A study offers more insight into our struggle with distractions. It found that our brain waves pulsate (搏动) at different frequencies depending on the type of external stimuli. The rhythm is faster for automatic stimuli but slows down for tasks we consciously choose to focus on.
Just think about it: You’re involved in a project, and then your phone receives a text message.
| A．But it is double-edged. |
| B．Some distractions can be avoided. |
| C．Statistics reveal how common this issue is. |
| D．They’re also persistent and endless in getting our attention. |
| E．The sound of it is loud enough to interrupt your concentration. |
| F．Stimulating our interest and increasing the speed of our work are important. |
| G．This makes maintaining focus in the noisy world an ever-increasing challenge. |

An Extension of the Human Brain
Other people can help us compensate for our mental and emotional deficiencies (欠缺), much as a wooden leg can compensate for a physical deficiency. To be exact, other people can extend our intelligence and help us understand and adjust our emotions. When another person helps us in such ways, he or she is participating in what I’ve called a “social prosthetic (义肢的) system.” Such systems do not need to operate face-to-face, and it’s clear to me that the Internet is expanding the range of my own social prosthetic systems. It’s already a big bank of many minds. Even in its current state, the Internet has extended my memory and judgment.
Regarding memory: Once I look up something on the Internet, I don’t need to keep all the details for future use — I know where to find that information again and can quickly and easily do so. More generally, the Internet functions as if it were my memory. This function of the Internet is particularly striking when I’m writing; I’m no longer comfortable writing if I’m not connected to the Internet. It’s become natural to check facts as I write, taking a minute or two to dip into PubMed, Wikipedia, or other websites.
Regarding judgment: The Internet has made me smarter in matters small and large. For example, when I’m writing a textbook, it has become second nature to check a dozen definitions of a key term, which helps me dig into the core and understand its meaning. But more than that, I now regularly compare my views with those of many others. If I have a “new idea,” I now quickly look to see whether somebody else has already thought of it, or something similar — and I then compare what I think with what others have thought. This certainly makes my own views clearer. Moreover, I can find out whether my reactions to an event are reasonable enough by reading about those of others on the Internet.
These effects of the Internet have become even more striking since I’ve begun using a smartphone. I now regularly pull out my phone to check a fact, watch a video, read weibo. Such activities fill the spaces that used to be dead time (such as waiting for somebody to arrive for a lunch meeting).
But that’s the upside (好处). The downside is that in those dead periods I often would let my thoughts flow and sometimes would have an unexpected insight or idea. Those opportunities are now fewer and farther between.

Ten years ago, no one thought that using computers could become a compulsive behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades, and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society,
Because of the change in their behavior, they begin to isolate themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life.Although they feel confident on the computer, they are not confident with real life friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.
