Staying Safe on the Internet
________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________2 . Millions of people go online each day only for fun or to pass the time. Besides the list of things like books, music, movies and televisions, you can now add surfing the Internet as a primary way of entertainment and passing the time.
So how many people actually use the Internet today? According to some reports, about 40% of the world’s population has a connection with the Internet. That’s a huge increase from only 1% in 1995.
The number of Internet users continues to grow. In 2005, the number of Internet users was more than one billion. Just five years later, that number doubled to over two billion. In 2014 that number passed the three billion mark!
Today, about 75% of all Internet users live in the top 20 countries. The other 25% are spread out amongst the remaining countries. The country with the most Internet users is China with over 640 million users. The total is more than the next three countries—the United States, India and Japan—combined.
Of all those billions of Internet users, a large part of users are children. From computers in schools to mobile devices, children are growing up in a connected world. Studies have shown that over 75% of children spend more than two hours each day of “screen time”, which means time is spent in front of a computer or mobile device.
Too much “screen time” can be harmful to children. For example, too much screen time has been linked to many problems, such as high blood pressure, high cholesterol（胆固醇） and overweight. What’s more, school-age children who use a computer more than two hours per day are more likely to have emotional, social, and attention problems. Thus, if you’re one of the 75% that spend more than two hours per day in front of a screen, consider cutting back and getting outside to enjoy the natural world.

3 . The American Academy of Pediatrics has warned about the potential negative effects of social media on young kids and teens. But the same risks may be true for adults. A review study suggests addiction symptoms (症状), such as failure to pay attention to personal life and escapism, appear to be present in some people who use Facebook excessively (过度).
A study also shows when people stop using the Internet, they also go through small but measurable physical effects. Rather than improving health, as frequent interactions (互动) with offline social networks do, the findings show that interacting with Facebook may predict the opposite result for young adults—it may undermine it.
In fact, another study found that social media use is linked to greater feelings of social isolation (隔离), mentally and physically. We fall into the trap of comparing ourselves to others as we check our Facebook pages. The study looked at how we make comparisons with others’ posts, in “upward” or “downward” directions—that is, feeling that we are either worse or better off than our friends. It turned out that both types of comparisons made people feel worse, which is surprising, since in real life, only upward comparisons make people feel bad. But in the social network world, it seems that any kind of comparison is linked to depressive symptoms.
All of this is not to say that there is no benefit of social media—obviously it keeps us connected across great distances, and helps us find people we had lost touch with years ago. But visiting social networks when you have some time to kill is very likely a bad idea. If you are feeling brave, try taking a little break, and see how it goes. And if you are going to keep “using” it, then at least try to use it reasonably.

4 . Online games are very popular among people. They make a large amount of money and have a large user base, including lots of teenagers. But now, new rules on online games have been introduced, which are aimed at fighting against addiction (成瘾) among underage players.
Adult players need to spend most of their time paying attention to work and family, and cannot play games as often as they want. However, underage players have more spare time, but less responsibility and self-control. Children without a clear purpose in life, where there is less family education and school management, might easily become addicted to all kinds of online games and online novels.
The most direct impact of an addiction to online games among underage players is on their psychological (心理) health. According to psychologists, people seriously addicted to games can become anxious, bad tempered, and avoid responsibility.
However, Chinese parents are more worried that their children will lack interest in studying if they become addicted to online games, as academic success is important for students. Additionally, when their children become addicted to such games, most parents do not know how to deal with the situation.
To carry out the new rules to the best effect, more specific issues need to be solved, such as managing foreign online games, ensuring that facial recognition technologies used by games companies have the wanted effect or making sure online game providers can only offer one-hour services to underage players on Saturdays and Sundays. While there are always loopholes (漏洞) in new rules, authorities should act quickly to close them.
There is no doubt that online games have harmful effects on young people. It is not acceptable for a large number of teenagers or those even younger, to become addicted to these games.
1. What’s the purpose of the new rules on online games?| A．To raise awareness of Internet safety. |
| B．To bring in new computer programs. |
| C．To reduce the grown-up user base. |
| D．To prevent the teenagers’ addiction. |
| A．They can learn more knowledge on the Internet. |
| B．They have more free time and less self-control. |
| C．They have purposes in life but lack higher education. |
| D．They maintain a sense of curiosity about the Internet. |
| A．How to reduce parents’ anxiety about kids’ study. |
| B．How to find loopholes in the popular online games. |
| C．How to control the service time of online game providers. |
| D．How to invent a facial recognition game for young players. |
| A．Confused. | B．Negative. |
| C．Supportive. | D．Uninterested. |
5 . Last month, I began my own two-week-long digital detox. I got the inspiration from the tech writer Paul Miller, who got away from the Internet for a whole year. It was not worth mentioning as against the time Miller spent offline, but it was the longest I had gone through without almost any Internet in 13 years.
Why did I do it? For a while I felt the urge to try fully disconnecting to free myself from the endless work. I wanted to take a break from it all for a couple of weeks at least to see what would happen. After all, throughout the last decade, I’ve been online 24 – 7, overreacting to my email inbox and social feed (传送) – living in a world where the line between the digital world and the real world gets a bit unclear at times.
I haven’t of course forgotten that I’m CEO of a social media company. My work is built around the premise (前提) that being connected makes our lives richer, more rewarding and more efficient. Still, I’d forgotten one key lesson along the way: moderation. As more and more of my life was spent scanning social feed and checking out my inbox, I realized that I needed to step back and get a whole new perspective.
So on my winter vacation to Mexico, I took a break from being active on the Internet for the entire trip. For the whole 14 days, I ate a lot of delicious fish tacos, surfed and fixed up my cottage on the beach. I didn’t write or send any emails. I didn’t scan any Top 10 lists of feed. The one I did give myself was checking my email inbox occasionally—just to make sure an emergency wasn’t unfolding while I was away.
What I learned from my short experiment was actually not too unlike what Miller learned. I didn’t end up discovering that technology is evil. In fact, I found myself reflecting on how technology over the last few years had let me experience some of the most rewarding and eventful moments of my life.
1. Why did the author begin digital detox for two weeks?| A．Because Miller recommended him to do so. |
| B．Because he was tired of his empty life. |
| C．Because he wanted to live a digital life. |
| D．Because he intended to experience an Internet-free life. |
| A．to a large degree | B．in an honest way |
| C．in an appropriate way | D．to a very small degree |
| A．To deal with emergencies. | B．For the sake of his health. |
| C．To find some delicious food to eat. | D．To watch Top 10 lists closely. |
| A．The author holds an objective attitude towards technology. |
| B．The author finds technology is harmful. |
| C．The author will advise digital detox completely. |
| D．The author will no longer use the Internet. |

8 . A new study has found that more than 30 percent of babies as young as 6 months old are using smartphones. The survey asked parents twenty questions about when their children were first exposed to mobile media devices. What makes everyone so alarmed is that the study has found that children are being exposed to mobile devices earlier than ever before.
But before we all jump on the judgment train, let’s stop and think about how much more ubiquitous smartphones are now than they were even five years ago. It’s not that parents have gotten lazier, which some reporters have suggested. It’s that more parents have access to smartphones that they can use to show family pictures to entertain a baby or play music that a toddler can dance with.
What the study didn’t address was how much time these babies are spending looking at smartphones. Nor did it assess what these babies are looking at. Is it 5 minutes of music in the grocery store while Mom or Dad gets the food into the cart? Or is it 30 minutes of watching videos while a parent sacks out on the couch? There is a big difference between the two scenarios (场景).
By the numbers, the study found that among babies younger than 1 year old, 52 percent had watched television on mobile devices, 36 percent had been allowed to scroll the screen, 15 percent had used apps and 12 percent had played video games. Around 25 percent of kids had already called someone at this age.
The American Academy of Pediatrics frowns upon any screen time for children under the age of two. But I don’t think we need to necessarily panic. I did not have a smartphone when my girls were this age but I can tell you right now that if I had owned one, there would have been many occasions when I would have gladly handed over my phone to play music or a video or even a video game if it would have calmed a screaming baby. They would have turned out just fine.
1. What would be the answer to one of the questions according to the study?| A．Some babies use smartphones very early. |
| B．Smartphones bring children convenience. |
| C．Children are clever enough to use electronic devices. |
| D．Science and technology are developing rapidly. |
| A．Unique. | B．Uncommon. | C．Non-existent. | D．Universal. |
| A．babies can use smartphones as they like |
| B．watching videos is interesting for babies |
| C．it doesn’t matter what babies are looking at |
| D．using smartphones too long is improper for babies |
| A．Nearly half of them had used apps on smartphones. |
| B．Half of them had watched television on smartphones. |
| C．About a quarter of them had made a telephone call to others. |
