WELCOME UNIT UNIT 3　 THE INTERNET 纯话题阅读 The Internet plays a big part in human life. 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. 经验贴14　词义猜测题，注意上下文线索，如：并列(and)、转折(but)、定义(mean/is)及举例(such as)提示词义。 纯话题阅读 2 As far as the Internet being a part of our lives—well, that_train_has_left_the_station. This expression means there is no going back to an Internet­free 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 (血压) in a young group: teenagers. The study results show that teens who spend at least 14 hours a week only may cause high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases. 纯话题阅读 3 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 say the study is the first to connect heavy web use with high blood pressure. 纯话题阅读 4 The lead researcher is Andrea Cassidy­Bushrow. She said, “Using the Internet is part of our daily life, but it shouldn’t ruin us.” Ms Cassidy­Bushrow adds that it is important for teens to take regular breaks 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. 篇章导读：本文是一篇说明文。文章主要介绍的是过度使用网络对青少年有害，父母应合理控制孩子的上网时间。 纯话题阅读 5 1．What does the underlined sentence “that train has left the station” mean in Paragraph 2?

Then, I have to shamefully admit that I turn my alarm off on my phone and scroll (滚屏) through WeChat. Before I’ve even had the chance to brush my teeth or wash my face I’m already right away attracted by whatever people are doing online. And I know it needs to change. 纯话题阅读 10 But the last time I was asked this question was about two months ago and have I changed my ways? Not even a little bit. We all know how unproductive social media can be. So why is it so easy to get addicted to (沉溺于) a huge mass of pretty pictures, and funny behavior and ideas? And why is it so hard to change? Lisa Lewis, a doctor in Brookline tells me the answer is simple. “It’s because the point of these apps is to keep you looking，” she says. “They want you to buy, and get you to follow and like. Their only purpose is to win your attention.” 纯话题阅读 11 She says you must have a purpose when it comes to using any social media apps. “Don’t just go on and scroll，” she explains. “Just like you wouldn’t walk up to the refrigerator and stare at what’s inside for no reason, don’t do the same with social media.” If social media is reducing your productivity and overall health, Lewis offers these steps： 纯话题阅读 12 First, set a goal whenever you use a social media app. If you use WeChat to get inspiration to exercise, do that and then get off it. Next, you can use a timer. These days you can set a timer for how many hours a day you spend on social media. Set it and stick to it. And finally, you can create a prize to strengthen the behavior. When you set that timer and stick to it, positively strengthen the behavior with anything from tasty food to things you’ve been eyeing on Amazon. 篇章导读：本文是一篇说明文。文章主要介绍了人们容易沉迷于社交媒体的原因，并提出解决方法。 纯话题阅读 13 5．What can we say about the author according to Paragraph 1?

Just as he was about to be offline, he saw a name he’d never seen there before, Susan. Her brief message was “Would someone help me？” Sean typed back, “What’s wrong？” A moment later he received this message, “I can’t breathe. Help me! I can’t get out of my chair.” 纯话题阅读 17 Oh, man, Sean thought. Pretending to be paralyzed (瘫痪) was a bad joke. Then he wondered what if she really was sick? “Hey, Mom.” he called. “There’s a kid here who’s sick or something.” Sharon looked at the computer screen. “It’s not just some game, is it？” she asked. The message was not a joke. Susan was actually a 20­year­old student, working late at night at a college library near Helsinki, Finland—almost 7，000 miles away from Sean’s home in Texas. While searching the Internet, she began to feel terrible pain all through her body. The library was silent and empty. The nearest phone was outside in the hallway. She couldn’t move that far. Any movement caused the pain to get worse. Then she realized she might get help on the Internet. 纯话题阅读 18 “I don’t think it’s a joke, Mom，” Sean said. And he typed, “Where are you？” After a long while, the letters appeared, “Finland.” Sean and Sharon couldn’t believe it. Not knowing what else to do, Sharon called the local police. Sharon explained the situation to the officer Amy Schmidt. Schmidt told Sharon to try to get the sick girl’s phone number. Texas police called the international telephone operator and asked to be connected to the proper agency (机构) in Finland. The call was put through to a nearby rescue station. The Texas police gave Susan’s address to the Finnish operator. When Sean heard that, he typed, “Help is on the way.” 纯话题阅读 19 In a few minutes, Susan heard people running down the hallway outside the door. Suddenly, the door opened. Emergency workers and three policemen ran in. Susan turned once more to the computer, “They are here. Thanks. Bye­bye.” Four days later, the police in Texas received a message from officers in Finland: “Thanks to her Internet friend, Susan has received medical treatment she badly needed. She is doing well.” 篇章导读：本文是一篇记叙文。文章主要讲述了12岁的Sean Redden (西恩·雷登)通过网络帮助了一位生命垂危的女孩。 纯话题阅读 20 8．What happened when Sean was about to get offline? A．His computer broke down.

These networks can provide teenagers with valuable support. Teenagers also use social media for entertainment and self­expression. And the platforms can expose teenagers to current events, allow them to communicate across geographic barriers and teach them about different kinds of subjects, including healthy behaviors. However, social media use can also negatively affect teenagers, distracting them, influencing their sleep, and exposing them to bullying (恐吓), rumor (谣言) spreading, untrue views of other people’s lives and peer pressure. 纯话题阅读 25 There are steps you can take to encourage responsible use of social media and limit some of its negative effects. Set reasonable limits. Talk to your teenager about how to avoid letting social media affect his or her activities, sleep, meals or homework. Encourage a bedtime routine that avoids electronic media use, and keep cellphones and iPads out of teenagers’ bedrooms. Set an example by following these rules yourself. Monitor your teenager’s accounts. Let your teenager know that you’ll be regularly checking his or her social media accounts. You might aim to do so once a week or more. And make sure you follow through. 纯话题阅读 26 Explain what’s not OK. Discourage your teenager from gossiping, spreading rumors, bullying or damaging someone’s reputation—online or otherwise. Talk to your teenager about what is appropriate and safe to share on social media. Encourage face­to­face contact with friends. This is particularly important for teenagers who are vulnerable to social anxiety disorder. Talk about social media. Talk about your own social media habits. Ask your teenager how he or she is using social media and how it makes him or her feel. Remind your teenager that social media is full of unrealistic images. 纯话题阅读 27 If you think your teenager is experiencing signs or symptoms of anxiety or depression related to social media use, talk to your child’s healthcare provider immediately. 篇章导读：本文是一篇说明文。文章主要介绍了家长可以用来帮助自己的孩子正确使用社交媒体的方法。 纯话题阅读 28 12．How does the author mainly develop the first paragraph?
