While some find joy in these changes, others face difficulties. Many seniors are discovering fun ways to use technology. Free online classes let them learn painting, gardening, or even how to use smartphones. For example, 72-year-old Grandma Zhang recently learned to make digital (数字的) birthday cards for her grandchildren. Video apps like WeChat help families stay connected. “I see my grandson’s face every day though he studies abroad,” said Mr. Li, 68, with a smile. Smartwatches are also popular—they check heart rates and remind users to take medicine. Some hospitals even let patients talk to doctors online, saving time for those who have trouble walking. However, not everything is easy. About 40% of people over 65 say technology changes too fast. Many have a hard time with small phone text, forget passwords, or worry about online tricks. “I once lost 500 yuan on my phone. Now I’m scared to use my phone,” shared Auntie Wang. To help, communities are taking action. Young volunteers teach seniors how to use phones safely every weekend. In Beijing, a 16-year-old boy named Xiaoming became a “tech-teacher” for his neighbors. “Mr. Chen learned to send emojis (表情)! He sends me a thumbs-up after each lesson,” Xiaoming said proudly. The government also opened special “tech-cafes” with large-screen computers and friendly guides. As 5G networks reach more places, even villages are joining the digital age. The key is to make technology kind to people of all ages. After all, today’s young “phone experts” will one day be seniors (较年长者) too. By working together, every age can enjoy the benefits of a connected world. Digital life not only brings us joy but also prepares us for future jobs. Many jobs today require computer and internet skills. So, let’s enjoy digital life wisely, stay safe, and keep a balance. This way, we can make the most of it and be ready for the future. 1．How many good things does technology bring to seniors? A．One. B．Two. C．Three. D．Four. 2．What does “thumbs-up” mean in Paragraph 3?
