Many kids do! 1 Imagine your eyes are like bouncy (弹力) balls. When you look at a screen for a long time, your bouncy balls get tired. 2 That’s because your eyes need breaks to rest. 3 The bright lights and exciting videos keep your brain busy, even when it’s time to rest. If you don’t sleep well, you’ll feel bad and tired during the day, and it’s harder to learn things in school. Sometimes, TikTok videos show things that aren’t true or might be scary. 4 Talking to a grown-up about what you see can help you understand what’s true and what’s not. Finally, spending too much time on TikTok means you might miss out on doing other fun things! Playing outside, reading books, drawing pictures or playing with friends are all really important. 5    So, let’s make a deal. We can watch some fun TikTok videos, but we’ll also make sure to take breaks, get enough sleep, and do lots of other fun things too. Remember, balance is key! 根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使文章意思通顺、内容完整。 A．Too much TikTok can also make it hard to sleep. B．They start to hurt, and you might get headaches. C．These activities help you learn and grow in lots of different ways. D．It’s important to remember that not everything you see online is real. E．But did you know that watching too many videos on TikTok can be bad for you? 六、阅读理解。 When someone’s heart suddenly stops, we can use an AED (除颤仪) to save him or her.

Often we are too busy or feel lazy. But we should try our best to exercise every day. Exercise is good for our body. When we exercise, our body changes. Exercise develops our muscles and makes us stronger. When we exercise, we use energy. This keeps our weight down. Being overweight puts stress on our body. It can cause pain in our back and knees, and even cause more serious problems such as heart disease later in life. Exercise is also great for our brain. During exercise, our heart beats faster and we breathe harder. Our brain gets more oxygen because of this, and that helps our memory improve. Scientists also tell us the body makes more of certain chemicals after exercise. This helps us to learn and think well. So, when you have trouble with your homework, do some exercise, then try again! Exercise also helps us to feel happier. When we exercise, our brain makes special chemicals. These chemicals can relax our body and calm our mind. Feeling fit can also make us feel better and more confident about ourselves. When we play a sport with others, we can even make new friends. Remember: Health is wealth. The more you exercise, the healthier you become. Try to make exercise a part of your life. 阅读短文，根据要求完成下面各小题。 1．What does the writer tell us to do every day? ____________________________________________________________________ 2．What problem(s) can being overweight cause? ____________________________________________________________________ 3．When you have trouble with homework, what can you do in the passage? ____________________________________________________________________ 4．What does Paragraph 4 (第4自然段) mainly talk about? _____________________________________________________________________ 5．Please give a title (题目). _____________________________________________________________________ 1 / 7 学科网（北京）股份有限公司 $ Unit 7 Avoid Danger, Keep Safe 课时4 Section B 1a-2b 分层作业 核心知识速记 01基础达标 02能力提升 03拓展培优 04思维进阶 race /reɪs/ n. 比赛；竞赛 名词复数：races 1. running race（跑步比赛）2. car race（汽车比赛） check /tʃek/ v. 检查；查看 动词：过去式 checked，过去分词 checked 1. check sth.（检查某物）2. check in（登记入住；报到） protect /prəˈtekt/ v. 保护；防护 动词：过去式 protected，过去分词 protected protect sb./sth. from sth.（保护……免受……） push /pʊʃ/ n. 推；鼓励；v. 推动；促使（达到某程度或状态） 动词：过去式 pushed，过去分词 pushed；名词复数：pushes 1. push sth.（推某物）2. give sb. a push（推某人一把；鼓励某人） speed /spiːd/ n. 速度 名词：不可数（表“速度”时）；复数 speeds（表“不同速度”时） 1. at a high speed（高速地）2. speed up（加快速度） hit /hɪt/ v. 打；撞击 动词：过去式 hit，过去分词 hit hit sth./sb.（撞击某物/某人） stone /stəʊn/ n. 石头；石块 名词复数：stones N/A roll /rəʊl/ v.
