1 . The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language and connect with family and friends.
As far as the Internet being a part of our lives —well, that train has left the station. This expression means 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 an unlikely group— teenagers. The study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure. High blood pressure can cause heart and kidney (肾) disease. It is also closely linked to some forms of dementia (痴呆), a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people from 14 to 17 years old participated in it. One hundred and thirty-four of the teens were described as “heavy Internet users.” Researchers found that out of these 134 teens, 26 had high blood pressure.
The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement she said, “Using the Internet is part of our daily life but it shouldn’t consume us.” For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week.” Ms. Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity.”

2 . 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.

6 . 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.

| A．the more mental habits can be improved | B．the more they have to fight to stay focused |
| C．the more they are influenced in shape | D．the more online activities they can enjoy |
| A．Is the Net gradually changing us? |
| B．Long articles are hard to read nowadays. |
| C．Do people lack concentration to cover Web pages? |

9 . Because computer knowledge is important in our society today, many parents believe that the earlier their children begin to use the computer, the better. Accordingly, most children are spending a large amount of time on computers during their preschool years. But is it healthy for preschoolers to use computers? And if so, how can parents decide how much computer time is proper?
Some studies have shown that using computers from an early age has several advantages. Preschoolers who have already attended computer classes come out top in their studies. Also, playing educational games contributes to their language learning and math.
The greatest benefits, though, are gained when preschoolers use computers side by side or when they work with adults. In these situations, preschoolers develop cooperative（合作的）problem-solving skills. They also have the chance to communicate with others, which will reinforce their learning.
Despite many benefits, experts also point out disadvantages of preschool computer use. Preschoolers’ muscles（肌肉）and bones are still developing, but computers and furniture are seldom set up properly for them. "Most parents, says Peter Buckle of the Robens Centre for Health Ergonomics, "seem unaware of the possible dangers of preschoolers sitting for long periods unsupported with necks and wrists（手腕）damaged."
Another problem arises when parents put educational games into computers and believe it’s better for their preschoolers to play these games than sit in front of a TV Educational expert and teacher Jane Healy disagrees. She doesn’t believe there is much difference between the two. "Simply watching a screen is not the same as real mental activity." Healy says. She suggests that reading together, having family discussions, or playing are much more valuable. Besides, Healy also questions whether some popular computer games have educational value. "Some," she says, "may even damage creativity, attention and motivation（动力）.
To make the computer valuable for you and your preschoolers, you need to decide on rules and time limits. When purchasing（购买）software for your preschoolers, look for programs that offer many different functions, which can help improve preschoolers creativity and ability to solve problems. Above all, try your best to stay with your preschoolers rather than leaving them alone before the computer.
Here are some additional tips:
*Adjust（调整）the computer and furniture for your preschoolers use;
*Manage your preschoolers’ computer activities;
*Limit the amount of time your preschoolers spend on the computer
