The backpack has a small sensor inside. When you leave something important — like your keys, wallet, or books — behind, the sensor sends a signal to your phone. Your phone then vibrates and shows a message: "You forgot your keys!" The idea came from a common problem. Every day, the students saw classmates rushing back to the classroom because they had forgotten their homework or lunch boxes. "We thought a backpack should do more than just carry things," said one team member. "It should help you remember." The team spent six months designing the backpack. They tried over 20 different sensors before finding the right one. The biggest challenge was making the battery last long enough. After many tests, they finally created a battery that can work for a whole month on one charge. Their invention won first prize in a national science fair. Now, a company in Shenzhen is working with the students to make the backpack available in shops. "We hope our idea can help students everywhere," the team said. 1. What is the main function of the smart backpack? A. To carry more books. B. To warn you about forgotten things. C. To play music while walking. D. To charge your phone. 2. Where does the sensor send the signal when you forget something? A. To the backpack. B. To your keys. C. To your phone. D. To the classroom. 3. What was the biggest challenge the team faced? A. Finding the right colour. B. Making the battery last long enough. C. Paying for the materials. D. Selling the backpack. 4. What does the underlined word "available" in Paragraph 4 probably mean in Chinese? A. 昂贵的 B. 可获得的 C. 破旧的 D. 危险的 5. What is the best title for the passage? A. How to Win a Science Fair B. The History of School Backpacks C. A Smart Backpack That Remembers for You D. Students from Shenzhen 三、阅读理解 ① Marco is an Italian travel blogger. He had a serious tooth problem that needed treatment. In his home country, he was told he would have to wait at least three months to see a specialist. The total cost would be more than 5,000 euros. So he made an unusual decision: he booked a flight to Shanghai to see a dentist. ② Marco had visited Shanghai before. Within two days of his arrival, he had a full examination at a modern dental clinic. The dentist explained the treatment plan clearly in English, and all the equipment was brand new. About one week later, his treatment was finished. ③ The total bill came to 9,800 yuan, which is about 1,300 euros. Marco said the same treatment in Italy would have cost him at least 5,000 euros. Even after adding his flight and hotel costs, he still saved money. He posted a video about his experience on the Internet. ④ "The speed and the quality of care were amazing," he wrote. "The clinic was clean, the staff were friendly, and I got everything done in just one week. It was worth every cent." ⑤ Marco's video went viral online. It shows a growing trend: more and more foreigners are choosing China for affordable and high-quality medical treatment. ⑥ At present, China is making it easier for foreign visitors to receive medical care. Many top hospitals in big cities now have special international service centres with English-speaking staff. 1. Why did Marco decide to go to Shanghai for dental treatment? A. He wanted to travel around China. B. He had no dentist in Italy. C. He would have to wait too long and pay too much in Italy. D. His friend worked in a Shanghai clinic. 2. How did Marco feel about his experience in Shanghai? A. Angry and disappointed. B. Worried and nervous. C. Surprised and satisfied. D. Bored and unhappy. 3. 创新考法·篇章结构 What is the structure of the passage? A. ①/②③④/⑤⑥ B. ①②/③④/⑤⑥ C. ①/②③/④⑤⑥ D. ①②③/④⑤/⑥ 4. 拓展迁移 What can we learn from Marco's experience? _______________________________________________________________ 5. 拓展迁移 Why are more and more foreigners choosing China for medical treatment? _________________________________________________________________________ 四、句子还原 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。 Have you ever thrown away a plastic bottle and wondered if it could be used again? 1___ Plastic recycling is not new, but traditional methods have big problems. When plastic is melted down and remade, it becomes weaker each time. 2___ After just a few rounds, the plastic is no longer useful and ends up in landfill. A team of scientists in Shanghai has found a better way. They use special bacteria that can "eat" plastic and break it down into its basic building blocks. 3___ These building blocks can then be used to make brand-new plastic that is just as strong as the original. The process is cleaner and uses less energy than traditional recycling. 4___ A single bacteria can break down a plastic bottle in about 48 hours. 5___ The team hopes that one day, every plastic bottle could be recycled this way. "We want to turn waste into a resource," said the lead scientist. "With this method, plastic pollution could become a thing of the past." A. It is also surprisingly fast. B. However, there is still a long way to go. C. Soon, plastic may become as valuable as gold. D. After about three rounds, it is usually too weak to use. E. The scientists have already made a lot of money from it. F. These building blocks are then used to make new plastic. G. Most people never think about what happens to it next. 1. ___ 2. ___ 3. ___ 4. ___ 5. ___ 五、任务型阅读 In the fairy tale "Cinderella", the wicked stepmother wants to stop Cinderella from going to the ball. She gives Cinderella an impossible task: to sort a huge pile of mixed grains before midnight. Thanks to some helpful mice and birds, Cinderella finishes in time, and everyone lives happily ever after. But in real life, sorting tiny things quickly is no fairy tale — it is a serious problem. Every day, factories around the world need to sort millions of tiny objects, from rice grains to medicine pills. 1___ Doing it by hand is slow, boring, and often full of mistakes. This is where an amazing invention called "optical sorting" comes in. Optical sorters use cameras and clever computer programs to look at each object as it passes by at high speed. 2___ If something is the wrong colour, shape, or size, a puff of air blows it off the line in just a fraction of a second. The technology was first developed in the 1970s to sort potatoes. 3___ Today, optical sorters are used in food factories, recycling plants, and even in mining. They can sort thousands of objects every minute — far faster and more accurately than any human. One of the newest uses is in recycling. 4___ This means more plastic can be reused instead of being thrown away. Some advanced sorters can even identify different types of plastic that look almost identical to the human eye. So the next time you throw a plastic bottle into a recycling bin, remember: a wise old fairy tale might say "Bibbidi-Bobbidi-Boo", but in the real world, it is cameras, computers, and puffs of air that do the real magic. 根据短文内容，回答下列问题。 1. What impossible task does the stepmother give Cinderella? __________________________________________________________________ 2. Why is sorting tiny objects by hand a problem? __________________________________________________________________ 3. How do optical sorters identify objects? __________________________________________________________________ 4. What do sorters use to blow away the wrong objects? __________________________________________________________________ 5. What can we learn from the passage? __________________________________________________________________ 答案与解析 一、完形填空 1. A（wrong 错误的。奶奶手抖，经常"吃错药"。） 2. C（build 建造、制作。他想制作一个小装置。） 3.
