Study author Brent Coker said, “Surfing the Internet at times helps increase an employees attention.”“People need to relax for a bit to get back their attention，” Coker said on the universitys 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 days work, and as a result, increases productivity (生产效率)，” 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. “Thats 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.语篇解读：一项研究表明，员工上班时间适度使用网络可以提高生产效率。1What does the University of Melbourne study mainly show?APeople who surf the Internet are good employees.BNot everyone surfs the Internet for fun during office hours.CThe Internet is becoming more and more important in peoples life.
