Choose the best answer according to the passage (阅读短文并选择最佳答案) (12 points) Technology That Helps People Live Independently Assistive technology includes products and services that help people with disabilities communicate, move, study or work. Some tools are simple, such as a walking stick with a special handle. Others use digital technology. A screen reader changes written words into speech, while a camera can recognise objects and read signs aloud. These tools do not remove every difficulty. They may be expensive, and users sometimes need training. However, good design can give people more choices. For example, a person with limited movement may use a voice assistant to send messages, control lights and search for information. The person can complete tasks without asking another adult each time. Experts say that users should be involved when new tools are designed. Their experience helps engineers understand real needs. Technology is most useful when it is safe, reliable and easy to use. (assistive technology 辅助技术; screen reader 屏幕阅读器) 37. What is assistive technology designed to do? A.

Answer the questions (根据短文回答问题) (14 points) A School Digital Wallet Project A secondary school in Shanghai conducted a small survey about digital payments. Students recorded how often they used electronic cards, QR codes and cash during one week. The project did not ask students to share private account numbers. Instead, they counted payment methods and wrote down one advantage and one possible problem for each method. The results showed that QR-code payments were quick and convenient in shops near the school. Electronic cards were useful when students wanted to store several services in one place. Cash still helped when a phone battery was dead or a network was unavailable. In class, groups discussed how to use digital money wisely and how to protect personal information. The teacher concluded that a digital wallet is only a tool. It can make payment easier, but users must check the amount, protect passwords and keep another method available. The survey also reminded students that a connected digital life should include careful choices, not just the latest technology. (QR code 二维码) 52.
