Its multi-functional platform integrates messaging, social media, and mobile payment, making daily life more efficient. However, this powerful tool can also become a significant source of distraction. The constant flow of messages from group chats and the temptation of “Moments” and mini-games can easily pull students away from their studies. It is not uncommon for a student to intend to quickly check a class notification, only to find themselves scrolling through feeds or watching videos for an extended period, leaving homework neglected. Educators and parents express growing concern over this issue. They observe a decline in students’ attention spans and an increase in procrastination linked to excessive use of the app. The key, they argue, is not to forbid WeChat entirely, which is impractical, but to cultivate digital discipline. Students are encouraged to use the app’s “Do Not Disturb” mode during study sessions and to set strict time limits for its recreational use. Learning to use technology as a servant rather than letting it become the master is a crucial skill in the digital age. When used mindfully, WeChat can be a valuable assistant; when used excessively, it hinders academic progress and personal well-being. 16．What is the main advantage of WeChat for students mentioned in the passage? A．It helps them play games with friends. B．It allows them to shop online easily. C．It enables real-time communication for study. D．It lets them watch movies for free. 17．What is the major concern about students using WeChat? A．It is too expensive for students to use. B．It might distract them from their studies. C．Its payment system is not secure enough. D．It makes students communicate less in person. 18．What does the word “procrastination” in the second paragraph most likely mean? A．Delaying or postponing tasks. B．Improving academic performance. C．Communicating more effectively. D．Focusing intensely on studies. 19．Which of the following is a suggested solution to manage WeChat use? A．Deleting the app permanently. B．Using “Do Not Disturb” mode during study time. C．Only using it for playing games. D．Avoiding all group chats. 20．How does the author describe WeChat in the conclusion? A．As a completely harmful application. B．As a tool that can be either helpful or harmful. C．As the only reason for students’ poor grades. D．As an outdated form of technology. 五、短文填空 Huang Hexiao lives in Shanghai.
