译林版八年级下册Unit3 The world at one click 阅读理解专项训练 (单元话题：网络与数字生活) 一、阅读判断（Reading Judgment） 要求：根据短文内容，判断句子正误，正确写T，错误写F。 （一）Online Learning in the Digital Age Online learning has become a key part of modern education, but it’s not just about watching videos on the Internet. A good online course uses AI to make a personal learning plan for each student. It can track your learning speed, find out your weak points and give you extra exercises in time. However, this kind of smart learning needs a stable Internet connection and a good learning habit. Many students find it hard to focus on studying when they are at home, as mobile phones and computer games are always around them. A recent survey shows that only 45% of middle school students can finish their online tasks on time without their parents’ help. Some schools have started to mix online learning with offline classes. They ask students to learn new knowledge online first, and then discuss and practice it in class. This "blended learning" model has been proved to be much more effective. But for students who live in poor rural areas, online learning is still a problem because of the lack of digital devices and Internet service. ( ) 1. Smart online courses can make personalized learning plans for students with AI. ( ) 2. All students can finish online learning tasks on time without parents’ help. ( ) 3. Blended learning combines online learning and offline classes together. ( ) 4. Online learning is easy for every student in different areas of the country. ( ) 5. The passage mainly talks about the advantages and problems of online learning. （二）The Dark Side of Social Media Social media helps us keep in touch with friends and know about the world easily, but it also has a dark side. First, it can waste a lot of time. Teenagers spend an average of 3 hours a day on social media apps, which takes up their time for studying and exercising. Second, there is too much false information on social media. Some people post untrue news to get more attention, and it’s hard for teenagers to tell right from wrong. Third, social media can cause social anxiety. Many teenagers compare their daily lives with the perfect photos and videos on social media, and they feel bad about themselves. What’s worse, some teenagers may meet bad people online. They may share their personal information carelessly and get into danger. To stay safe on social media, we should set a time limit for using it, learn to check the truth of information and never share our private details with strangers. ( ) 1. Teenagers spend three hours every day on social media on average. ( ) 2. It’s easy for teenagers to tell false information from true ones on social media. ( ) 3. Social media may make some teenagers feel anxious about their own lives. ( ) 4. Sharing personal information online with strangers is never dangerous. ( ) 5. The passage tells us how to use social media in a safe and proper way. 二、阅读选择（Reading Multiple Choice） 要求：阅读短文，从每题所给的A、B、C、D四个选项中，选出最佳答案。 （一）How the Internet Changes Our Shopping Habits Before the Internet was popular, people had to go to physical stores to buy things.

Online shopping also lets you compare prices of the same product in different shops easily, so you can buy things at a lower price.
