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, leading to a higher total Internet attention for a day's 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. “That's not always a good idea.”

However, Coker said the study looked at people who surfed the Internet in moderation, 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.

1．What does the University of Melbourne study mainly show?

A．People who surf the Internet are good employees.

B．Not everyone surfs the Internet for fun during office hours.

C．The Internet is becoming more and more important in people's life.

D．Surfing the Internet for fun at times during office hours increases productivity.

2．The underlined word “block” in Paragraph 4 means “________”．

A．stop B．organize

C．protect D．separate

3．What can we infer from the last paragraph?

A．Those who never surf the Internet have the lowest productivity.

B．Spending too much time surfing the Internet reduces productivity.

C．Most people don't surf the Internet in moderation during office hours.

D．People should spend as little time as possible surfing the Internet.

Ⅲ　概要写作

阅读下面短文，根据其内容写一篇60词左右的内容概要。

Playing endless games of hide­and­seek with your toddler can get tired very quickly. And sometimes parents need a break from pretending not to know the very obvious spot where their child is hiding. Well, you no longer have to feel guilty about letting your kids sit down in front of the television for an hour or two, because it's been proven that, in certain circumstances, screen time for your kids can actually be beneficial.

The key thing to remember is that unsupervised and too much screen time isn't good for your kids, but some situations let you relax and will keep your kids entertained. One example is video chatting with family. The American Academy of Pediatrics reported that maintaining strong relationships with your family members that live far away is an important part of development. Being able to visually see their faces and chat with them at the same time is good for your kids, even if it's on a screen. So let your little child sit on the couch, having a video chat with Grandma and Grandpa, and you can go and catch up on other things around the house.

Another way to incorporate screen time in a beneficial way is to watch TV together. Turn on an educational kid show and sit next to your toddler to answer any questions that they might have. The AAP says that a few hours of television a week is fine as long as you make it a family activity and encourage your kids to ask questions about the show. One show in particular that can be extremely beneficial to watch together is Daniel Tiger's Neighborhood on PBS. Researchers at Texas Tech University reported that kids who watched 10 episodes over a two­week period had higher levels of confidence, and they were able to recognize emotions better.

So don't feel guilty at letting your kids sit inside for a little while; all parents need a break.

1.                                                                                                                                                      答案：D　细节理解题。根据第二段中的“people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not”可知，在上班时间，偶尔上网以娱乐放松自己，可以提高工作效率。故选D。
