It's also important to remember: don't share personal information (like your home address or phone number) online. Digital technology is a useful tool, but it's up to students to use it in a responsible way. ( ) 41. What is the main idea of the passage? A. How students play online games. B. The good and bad sides of digital technology for students. C. Why digital technology is bad for students' eyes. D. How to buy cheap digital products for students. ( ) 42. According to the passage, what can students do with online libraries? A. Play online games. B. Watch short videos. C. Find study materials. D. Chat with friends. ( ) 43. What challenge does digital technology bring to students? A. They can't find online resources. B. They may get distracted from studying. C. They don't know how to use video calls. D. They can't finish homework on time. ( ) 44. How can students protect their eyes when using digital devices? A. Use devices for 5 hours without stopping. B. Keep devices very close to their eyes. C. Take short breaks every 30 minutes. D. Turn off all lights when using devices. ( ) 45. What does the passage suggest students do? A. Stop using digital technology completely. B.

It looks like a small speaker and connects to the internet. You can control it with your voice — no need to use your hands. What can it do? First, it controls other smart home devices. For example, you can say "Turn on the bedroom light" or "Lower the air conditioner temperature", and it will do it right away. Second, it helps with daily tasks: it can set alarms, remind you of birthdays, or tell you the weather forecast every morning. Third, it can play music, stories, or English podcasts when you ask. Some models even help with study — you can ask, "What's the meaning of 'digital'?" and it will explain. Setting up a smart home assistant is easy. You just need to download its app on your phone, connect the assistant to your Wi-Fi, and follow the app's instructions. Most models are not expensive, so many families can buy them. But you need to care about privacy: since it listens to your voice commands, choose a trusted brand and read its privacy policy first. 60.What does a smart home assistant look like? ________________________________________. 61.How can people control a smart home assistant? ________________________________________. 62.What can a smart home assistant do to control home devices?

I felt nervous at first, because I didn't know how to share the board with my teammates. My teammate Lily helped me: we downloaded the app, created a new whiteboard, and she sent me a link. I clicked the link and joined her. We could write equations, draw graphs, and type notes on the same screen at the same time — even though we were at home! At first, I made mistakes (like deleting her notes by accident), but we laughed and fixed it together. We finished our project in two hours, much faster than doing it alone. This experience taught me that digital tools make teamwork easier. Now, I often use the app for other group work. It's amazing how a small app can connect people and help us work better!（132 词） 学科网（北京）股份有限公司 $
