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 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 (生產(chǎn)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 (適度)，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. 【語篇解讀】　一項(xiàng)研究表明，員工上班時間適度使用網(wǎng)絡(luò)可以提高生產(chǎn)效率。 1．What does the University of Melbourne study mainly show?

WiFi is short for “Wireless Fidelity” (無線上網(wǎng))．It allows laptop puters and personal digital assistants to connect to the Internet at high speed by radio signal. A person with a WiFi enabled puter can connect to the Internet when near one of the networks access points.The place covered by one or several access points is called a hotspot.Google has already set up two “hotspots” in the US city of San Francisco which provide a free WiFi service. The WiFi technology even allows users to enjoy a free Internet phone service.Some scientists argue that WiFi may replace mobile phone networks. WiFi is still limited to a few cities，where there are “hotspots”．But its capability(容量)of sending information has already done better than that of the mobile phone network，even that of 3G (3rd generation telemunication technology)．Some scientists have started to call WiFi 4G. In addition to a high speed Internet connection，WiFi has other advantages pared to mobile phones.WiFi is global.The same WiFi system works in different countries around the world.Different from using cell phones，you dont need to change puters to use Internet phones when you go to other places and most importantly，many Internet phones cost you nothing at all. 【語篇解讀】　文章主要對無線上網(wǎng)技術(shù)作了介紹。 5.

Which of the following is NOT the advantage of WiFi? A．The high speed Internet connection. B．Many free Internet phones. C．Using the same puters for Internet phones. D．Used in all the US cities. D　[根據(jù)文章第一段第二句可知無線上網(wǎng)服務(wù)還只在美國一些城市適用，所以D項(xiàng)錯誤。] 7.
