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 cause 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。文章主要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. D．The Internet has improved people's life. 答案：B 解析：句意理解题。根据下文“There is no going back to an Internet-free life.”可知，是对上文的解释说明，由此猜测“that train has left the station”在本段中意思是“生活中找不到没有互联网的地方”。 2．What can we know about the study according to Paragraph 4? 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. 答案：A 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. 答案：D 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.”可推知，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?

But is it possible that Kaylee's online friendships could be making her lonely? That's what some experts believe.Connecting online is a great way to stay in touch, they say.However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships. Could this be true? During your parents' childhoods, connecting with friends usually meant spending time with them in the flesh．Kids played Scrabble around a table, not Words With Friends on their phones.When friends missed each other, they picked up the telephone.Friends might even write letters to each other. Today, most communication takes place online.A typical teen sends 2，000 texts a month and spends more than 44 hours per week in front of a screen.Much of this time is spent on social media platforms (平台)． In fact, in many ways, online communication can make friendships stronger, “There's definitely a positive influence.Kids can stay in constant contact, which means they can share more of their feelings with each other，” says Katie Davis, co-author of The App Generation. Other experts, however, warn that too much online communication can get in the way of forming deep friendships.“If we are constantly checking in with our virtual words, we will have little time for our real-world friendships，” says Larry Rosen, a professor at California State University.Rosen also worries that today's kids might mistake the “friends” on the social media for true friends in life.However, in tough times, you don't need someone to like your picture or share your blogs.You need someone who will keep your secrets and hold your hand.You would like to talk face to face. 语篇解读　本文是一篇议论文。文章主要论述了现在的青少年把更多的时间用于网上交友，这样的现象让专家很担忧。专家认为青少年如果不断地关注虚拟世界，他们将几乎没有时间在现实世界建立真正的友谊。 5．What is the purpose of the first paragraph? A．To summarize the text. B．To tell about true friends. C．To bring up a discussion. D．To encourage online friendship. 答案：C 解析：写作目的题。根据第一段“Thirteen-year-old Kaylee...a lot of time with them.”可推知，第一段阐述了一种社会现象，目的是提出一个讨论的话题，从而引出下文对于这个话题的讨论。故选C。 6．What does the underlined part “in the flesh” mean in Paragraph 3? A．In person. B．In advance. C．In any case. D．In full measure. 答案：A 解析：词义猜测题。根据画线短语前的“During your parents' childhoods”和画线短语后的“Kids played Scrabble around a table, not Words With Friends on their phones.”可推知，在你父母的童年时期，与朋友相处通常意味着亲自花时间与他们在一起。孩子们围着桌子玩拼字游戏，而不是在手机上玩Words With Friends。由此可知，画线短语in the flesh意为“亲自”，故选A。 7．What is Katie's attitude towards online communication? A．Worried. B．Positive. C．Confused. D．Unconcerned. 答案：B 解析：观点态度题。根据第五段中的“In fact...The App Generation.”可推知，Katie对网络交流持乐观态度。故选B。 8．What view does Rosen hold? A．It's wise to turn to friends online. B．It's easier to develop friendships in reality. C．Social media help people stay closely connected. D．Teenagers need focus on real-world friendships. 答案：D 解析：细节理解题。根据最后一段中的“Other experts...at California State University.”可知，Rosen认为青少年需要关注现实世界的友谊。故选D。 Ⅱ.阅读七选五(每小题2分，共10分) (2024·福建省泉州九中高一检测) It could be time to admit that you have a habit of putting off your tasks because you waste too much time on the Internet.If you are ready to cut down the time that you spend on it, it may seem difficult. 1 Pay attention to the time that you spend on the Internet. 2 Make sure you know how long it takes you to do each task and record exactly what you do.Then determine if an activity is really necessary.You'd be surprised at how much time you actually spend on necessary instead of unnecessary online activities. 3 Though it may feel strange to use technology to stop you from using technology, this is what we face today.To improve your work efficiency (效率)while you are online, use apps that block the access (通道)to websites you always go to.This way will tell you not to jump over to the websites when you have the task to do.
