人教版八年级上册Unit3阅读理解专项题
(一)Mobile phones are now as common as schoolbags for teenagers. A survey of 2,000 middle school students shows their usage and problems.Why do teens use phones 85% use them to chat with classmates or family. About 70% use phones for study—looking up words or watching educational videos. Besides these, 60% use them for entertainment, like games or short videos.Time spent on phones is worrying. On average, students use phones for 3.5 hours a day on weekends—almost as long as study time. On weekdays, it’s 1.8 hours, but 15% check phones over 20 times in class. This distraction hurts their focus.Uncontrolled use causes problems. Over 40% missed meals or stayed up late for games. Some play in class, leading to poor grades. 25% felt anxious without phones, a sign of addiction. There’s also risk from online strangers.Experts suggest: Set limits (2 hours weekends, 1 hour weekdays); use "study mode" to block game alerts; use phones for meaningful things (online book clubs, video-calling faraway grandparents); get together with friends for sports instead of chatting online.Phones are not "nothing but" toys. Used well, they’re fantastic tools. The key is staying in control.1.How much time do students spend on phones on weekends on average A. 1 hourB. 1.8 hoursC. 3.5 hoursD. 2 hours2.What does the underlined word "distraction" in Paragraph 2 probably mean A.

(二)AI in Daily Life: Convenience and ConcernsArtificial Intelligence (AI) has quietly entered our daily lives, bringing both fantastic changes and new questions. From our phones to our homes, AI is everywhere.▲They can set alarms, check the weather, or even answer study questions—especially helpful when our hands are busy. Besides these, smart home devices are also popular. AI can control lights, air conditioners, and even cookers, making life more comfortable and saving time.These uses bring clear benefits. AI improves efficiency: we no longer need to spend hours sorting information or adjusting home appliances. For the elderly or busy people, it can almost "lend a hand" in daily tasks.However, there are potential problems. It may probably lead to job losses—simple jobs like data entry or basic customer service might be replaced by AI. Privacy is another issue: AI systems collect our daily habits, which could be misused. Some people also worry that over-reliance on AI makes us less able to solve problems on our own.AI itself is not the problem. What matters is how we use it. With proper rules, AI can be a great helper rather than a troublemaker.1.Which of the followings is NOT true according to the passage:AI improves work efficiency in daily life.B. Smart voice assistants become familiar to people.C. People never worry about AI’s effect on privacy.D.

It was my first time going abroad, so I spent days packing clothes and checking my passport repeatedly, afraid to forget anything.When we arrived, our hotel was very comfortable, with a balcony facing a quiet street. The next morning, a local guide took us around. The scenery there took our breath away: red-tiled roofs under the blue sky, and thousands of artworks in the square.Besides visiting palaces and towers, we tried local food. To our surprise, there was even something like steamed chicken soup, which tasted familiar.One evening, we got together with other travelers in the hotel. We shared stories about our journeys, and the guide told us about the town’s history of fight against wars for peace.

Besides this, they bring other benefits. They reduce accidents caused by human mistakes, like tired driving. For passengers, the seats are comfortable, making long journeys less boring.However, problems still exist. Technology isn’t perfect yet: heavy rain or snow might make their sensors work poorly.
