The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive (富有成效的) 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, leading to a higher total Internet attention for a day's work, and as a result, increases productivity，” he said.

Now we live in a time when a family could have more than one computer. It is common for children to have their own computer or laptop. There are also phones and tablets (平板电脑) to think of.
