1 . Surfing the Internet for fun will make you a better employee, according to an Australian study.

The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author Brent Coker said, “Surfing the Internet at times helps increase an employee’s attention.”

“People need to relax for a bit to get back their attention,” Coker said on the university’s website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, and as a result, increases productivity ,” he said.

According to the study of 300 workers,70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software to block their employees from watching videos, using social networking sites or shopping online,” said Coker. “That’s not always a good idea.”

However, Coker said the study looked at people who surfed the Internet in moderation (适度),or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without,” he said.

“People need to relax for a bit to get back their attention,” Coker said on the university’s website.” Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day’s work, and as a result, increase productivity (生产效率),” he said.

8 . The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about.The list goes on and on.

As far as the Internet being a part of our lives, well, that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in a young group: teenagers.

The study results show that teens who spend at least 14 hours a week only online may cause high blood pressure, which makes their hearts and blood vessels(血管) work too hard. Over time, this extra pressure increases the risk of a heart attack. High blood pressure can also cause heart and other diseases.

The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers said the study was the first to connect heavy Web use with high blood pressure.

The lead researcher is Andrea Cassidy-Bushrow. She says, “Using the Internet is part of our daily life, but it shouldn’t ruin(毁坏) us.” Ms. Cassidy-Bushrow adds that it is important for teens to stop to have a rest regular from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week.

9 . Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.

Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots of things you can do. You can send E-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web(WWW).

There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.

There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at only time.

Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?

10 . Over the past few years I've had an uncomfortable sense that someone, or something, has been making changes to my brain. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Involving myself in a book or a lengthy article used to be easy. That's rarely the case anymore.

I think I know what's going on. For over a decade, I've been spending lots of time online. The Web has been a godsend to me as a writer. Research that once required days in the rooms of libraries can now be done in minutes by a few Google searches. Even when I'm not working, I'm scanning headlines or just tripping from link to link.

The Net is becoming a universal medium where information flows through my eyes and ears and into mind. The perfect recall of silicon memory can be a blessing to thinking. But that comes at a price. As the media theorist Marshall Mcluhan pointed out, media are not just passive channels of information. They supply the staff of thought, but they also shape the process of thought. And what the Net seems to be doing is weakening my ability for concentration. Once I was a driver in the sea of words. Now I zip along the surface like a flying swallow.

I'm not the only one. When I mention my troubles with reading to acquaintances, Bruce Friedman, a blogger, also has described how the Internet has changed his mental habits. His thinking has taken on a “staccato” quality. “I can't read War and Peace anymore,” he admitted. “I've lost the ability to do that.”

A recently published study suggests that when reading online, we tend to become "more decoders of information. We are not only what we read; we are how we read.
