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.

Electronic media such as email, instant messaging, video games, and television, has influenced almost every aspect of our daily lives.    1     While some media exposure can be useful and informative (增进知识的), too much screen time takes away from other activities. 

Screen time becomes a particularly important issue when discussing children’s use of media.Experts now recommend children’s screen time should be limited to no more than 2 hours per day, including television and non-school related computer usage.    2    

Unfortunately, it appears that this recommendation is not followed in most families. One recent study found that children between the ages of 8 and 18 spend nearly 45 hours per week watching television, playing video games, and surfing the Internet.    3     Besides, much of the electronic media that makes up children’s screen time is filled with inappropriate (不合适的) contents. 

    4     First, never allow televisions and computers in your child’s bedroom. Avoid using television, video games, and computer time as a reward for good behavior. Provide plenty of other recreational activities for your child to enjoy and set a good example for your child with regard to your own media usage. It’s important to serve as a model of healthy electronics use for your children.    5     Keeping the TV on for background noise all the time and scrolling (滚屏) through your phone any time will teach your child bad habits.

A．Most children know more about electronics than adults do.

B．Kids easily grow dependent on technology for entertainment.

C．Parents should think of ways to manage their children’s screen time.

D．This is more time than they spend doing homework,or reading for pleasure.

E．However,the effect of being all the time in front of a screen is not entirely positive.

F．So before you watch your favorite TV series,remember to set a good example.

G．Children under the age of 2 are generally encouraged to have no screen time at all.
