We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on. As far as the Internet being a part of our lives, well, that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in a young group: teenagers. The study results show that teens who spend at least 14 hours a week only online may develop high blood pressure, which makes their hearts and blood vessels (血管) work too hard. Over time, this extra pressure increases the risk of a heart attack. High blood pressure can also cause heart and other diseases. The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers said the study was the first to connect heavy Web use with high blood pressure. The lead researcher is Andrea Cassidy-Bushrow. She says, “Using the Internet is part of our daily life, but it shouldn't ruin (毁坏) us.” Ms. Cassidy-Bushrow adds that it is important for teens to stop to have a rest regularly from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week. 语篇解读：本文是一篇说明文。文章介绍了互联网在人类生活中扮演着重要的角色，但是过度上网会影响我们的健康，尤其是青少年。 1．What does the underlined part “that train has left the station” mean in paragraph 2? A．The train has changed its course. B．Life without the Internet is nowhere to be found. C．The Internet brings great changes to people's life.

A．There was no similar study like it before. B．Most of the young people had high blood pressure. C．Adult people aged above 17 took part in the study. D．Over half of the teens in the study were heavy Internet users. √ 解析：推理判断题。根据第四段最后一句“研究人员表示，这项研究首次将过度上网与高血压联系起来。”可知，以前没有过这样的研究。 3．Which of the following would Andrea Cassidy-Bushrow probably agree with? A．That teenagers shouldn't use the Internet. B．That the Internet will ruin human life in the future. C．That smartphones are more harmful than computers. D．That regular breaks are necessary when using the Internet. √ 解析：推理判断题。根据最后一段“Ms. Cassidy-Bushrow adds that it is important for teens to stop to have a rest regularly ... physical activity.”可推断出，安德里亚·卡西迪·布什罗建议在使用互联网的时候要有规律的休息。 4．What does the text mainly talk about? A．Heavy Internet users are mostly teenagers. B．Every coin has two sides — so does the Internet. C．Too much Internet use may be bad for teenagers.

Mostly because people don't really understand what digital privacy entails. People may 6 it is all about what they are doing, which is a small piece of the picture. However, 7 privacy has less to do with what you are doing, and more to do with who you are. On the Internet, data has high 8 . It's stolen, sold, collected and 9 . Whenever you download an app, visit a website or use a social media platform, chances are that company is collecting data on you. People are doing so much more online through their computers and mobile devices today. We make purchases, 10 medical conditions, arrange vacations, 11 friends and relatives, just about anything imaginable. With these actions, people are inadvertently (无意地) creating a huge digital paper 12 of data — about themselves. We all have things to hide. It could be how much money you make, your medical 13 or your bank account number. Hiding things is not bad. I don't think these are the types of things you'd like 14 on your social network for the entire world to see. This is why we must 15 to protect our right to privacy. Most apps offer privacy 16 for users. This gives you the freedom to know how much and what kind of information is shared. Always choose the least amount of data sharing. Always be cautious when sharing your name and location. 17 location services and deny access to your camera. Bluetooth technology offers 18 convenience. It also opens doors for security weaknesses. Make sure you turn off your Bluetooth when you are not using it. While there are options to place your Bluetooth activity in an invisible or undetectable mode, there are some malicious apps that can change that mode and 19 your device to threats. That's one more reason to have a security system in place. 语篇解读：本文是一篇说明文，主要介绍了网络隐私受到威胁的原因以及如何保护网络隐私。 5．A.typically B．naturally C．permanently D．reluctantly 解析：根据上文“Privacy is closing your ... closed doors”可知，现实生活中像睡觉时拉上窗帘这种类型的隐私是很自然的。typically“一般，通常”；naturally“自然地”；permanently“永久地”；reluctantly“不情愿地”。故选B。 √ 6．A.acquire B．attach C．assume D．attack 解析：根据下文“it is all about what they are doing”可知，空后的内容是人们的想法，人们认为数字隐私与他们正在做的事情有关。acquire“获得”； attach“贴上”；assume“认为”；attack“攻击”。故选C。 √ 7．A.online B．normal C．secure D．critical 解析：根据下文“On the Internet”可知，网络隐私与你在做什么关系不大，空格处意为“网上的”。故选A。 √ 8．A.possession B．cost C．amount D．value 解析：根据下文“It's stolen, sold, collected”可知，在互联网上，数据具有很高的价值。故选D。 √ 9．A.argued B．analyzed C．searched D．observed 解析：根据上文“It's stolen, sold, collected”及常识可知，在网上，数据被盗、被出售、被收集和被分析。故选B。 √ 10．A.look up B．look out C．look over D．look at 解析：根据下文“medical conditions”可知，我们在网上查询(look up)医疗状况。故选A。 √ 11．A.focus on B．glance at C．dispose of D．interact with 解析：根据下文“friends and relatives”可知，我们在网上和朋友、亲戚互动。focus on“集中于”； glance at“看一下”；dispose of“处理”；interact with“和……互动”。故选D。 √ 12．A.path B．trail C．extent D．loss 解析：根据上文“With these actions”和空后的“of data — about themselves”可知，我们在网上购物、查询医疗状况、安排假期，与朋友和亲戚互动，这些行为都会在网上留下痕迹(trail)。故选B。 √ 13．A.programs B．doubts C．records D．controls 解析：根据上文“We all have things to hide”和“your medical”可知，我们要把我们的医疗记录(records)隐藏起来。故选C。 √ 14．A.broadcast B．exchanged C．informed D．convinced 解析：根据下文“on your social network for the entire world to see”可知，让全世界都看到，说明是把这些事情在网上进行传播(broadcast)。故选A。 √ 15．A.compete B．strive C．complete D．rely 解析：根据上文“We all have things to hide”和“I don't think these are the types of things you'd like ______ on your social network for the entire world to see.”可知，我们有很多事情要隐藏起来，所以要努力保护我们的隐私权，故选B。 √ 16．A.stacks B．friction C．working D．settings 解析：根据下文“This gives you the freedom to know how much and what kind of information is shared.
