B [中学生视力保护之道]In recent years, more and more Chinese middle school students have been facing vision problems. A survey shows that over 60% of them wear glasses, and the number is still growing. Why do so many students have poor eyesight? One main reason is the heavy use of electronic devices. Many students spend hours every day on phones, computers, or tablets—for studying online, playing games, or chatting with friends. Staring at screens for a long time makes their eyes tired and dry. Another reason is bad reading habits. Some students read books in dark rooms, or they hold books too close to their eyes. Also, lack of outdoor activities plays a role. Students stay in classrooms or at home most of the time and don't get enough time to let their eyes relax in natural light. These vision problems bring troubles to students' lives. They may find it hard to see the blackboard clearly in class, which affects their study. Wearing glasses can also be inconvenient when doing sports. To protect their eyes, students should take action. First, cut down screen time. When using devices, take a 10­minute break every 20 minutes and look at something far away. Second, keep good reading habits—read in bright places and hold books at a proper distance. Third, spend more time outdoors. Playing sports or just walking outside helps eyes relax and stay healthy. It's important for middle school students to care about their eye health. By forming good habits, they can keep their eyesight better and enjoy a clearer world. 根据短文内容，补全下面方框中的句子，每空一词。 Vision problems of middle school students' in China ★In recent years, more and more middle school students in China have been facing 1.vision problems, with over 60% wearing glasses and the number still rising. ★The main reasons for students' poor 2.eyesight include frequent use of electronic devices, bad reading habits and lack of outdoor activities. ★Vision problems bring troubles to students' 3.lives, affecting their studies and making it inconvenient to wear glasses during sports. ★Students 4.should reduce screen time, keep good reading habits and do more outdoor activities to protect their eyesight. ★It's important for middle school students to pay attention to eye health; forming good habits can help maintain better eyesight and see more 5.clearly． 学科网（北京）股份有限公司 $
