Three weeks earlier, my family moved across the country after my mum changed jobs. 1 a new school in the middle of the term felt like hitting reset on my whole life. At lunch that first day, I sat at a corner table pretending (假装) to be very interested in my phone while 2 searching for “how to survive being the new kid”. Teen articles kept saying the same thing—feeling worried during a school transition (过渡期) is normal. That helped a little, but it still felt 3 . The first week was awful. I got 4 looking for the chemistry class, mispronounced a teacher’s name, and accidentally walked into the wrong classroom twice. But something small started to 5 when a boy asked if I wanted to join his group in the science lab. That made the whole day easier. One thing I learned quickly is that most students don’t 6 you as much as you think. Everyone is busy worrying about their own things. Slowly, I found a way to 7 . Instead of trying to do many big things right away, I focused on simple things, like learning two classmates’ names a week and asking one question in a class. Those small wins slowly built up my confidence. By the end of the term, things looked very 8 . I joined the photography club and started hanging out with my classmates after school. Changing schools in the middle of the term was not easy, but it taught me something important about resilience (适应力) and 9 . Feeling uneasy does not last forever. If you are the new kid right now, hang in there. The hallway that feels 10 today may become the place where you begin your new stage of life. 1．A．Starting B．Visiting C．Supporting D．Enjoying 2．A．suddenly B．excitedly C．angrily D．secretly 3．A．unwise B．unreasonable C．uncomfortable D．unimportant 4．A．lost B．beaten C．hit D．failed 5．A．return B．change C．increase D．move 6．A．push B．judge C．protect D．respect 7．A．show up B．stand out C．come back D．fit in 8．A．different B．strange C．common D．serious 9．A．honesty B．freedom C．confidence D．cooperation 10．A．familiar B．strange C．lucky D．different III 拔高练习 六、阅读理解 With the world becoming warmer because of climate change, mosquitoes are busy enlarging their living space. Now, a Chinese company has created a new device which can detect mosquitoes and then kill them. The device promises a future in which the peace and quiet of a summer evening is no longer broken by flying mosquitoes. The small, light device uses AI to discover mosquitoes as small as 2 millimeters (毫米). Within 0.003 seconds, it fires a high-energy laser (激光) that disables a mosquito midflight — a course that can hardly be seen by humans — and can kill up to 30 mosquitoes every second. The Chinese device is not alone in mosquito control. The Locus, which is made by a foreign company, uses computers to locate (定位) mosquitoes indoors. However, while the Locus focuses on location, the Chinese device goes a step further by killing mosquitoes. It is not easy to improve the accuracy rate (准确率). The early models of the Chinese device failed to correctly discover mosquitoes within a short distance, as they were influenced by background noise. After years of hard work, careful research and countless tests, the company put AI and laser technology together, enabling a discovery rate of over 95 percent within six meters. According to the World Health Organization (WHO), there are over 3,500 kinds of mosquitoes in the world. About 200 kinds can spread diseases. Every year, mosquitoes kill more than 700,000 people. Millions of people face this risk every day. This new Chinese device provides a safe and effective way to fight mosquitoes and protect people’s health. 1．What does the underlined word “detect” in Paragraph 1 most probably mean? A．Warn. B．Blow. C．Watch. D．Discover. 2．How does the writer prove the effectiveness of the device in Paragraph 2? A．By telling a story. B．By listing numbers. C．By making comparisons. D．By using experts’ words. 3．What is an advantage of the Chinese device over the Locus? A．Killing mosquitoes after location. B．Focusing on mosquitoes outdoors. C．Finding mosquitoes in a short time. D．Using AI to drive mosquitoes away. 4．What does Paragraph 4 mainly talk about? A．How the device was tested. B．The influence of noise on accuracy. C．How AI was used in the device. D．The road to a high accuracy rate. 5．What can we learn from the last paragraph? A．Most mosquitoes are dangerous. B．The Chinese device is of great use. C．Mosquitoes around us have been controlled. D．The Chinese device is praised by the WHO. B Do you like reading? Have you ever read with the help of AI? Now AI can quickly make book summaries (概要), allowing readers to know a book well in just a few minutes. However, real reading is more than that. “Even in the AI age, deep reading can never be replaced (取代),” says Professor (教授) Huang from Fudan University. Reading is a dialogue with the writer. When we read, we bring our own life experiences and feelings. We think about the writer’s ideas and form our own thoughts. Such special experiences cannot be offered by AI summaries or short online book reviews. Professor Chen of the Fudan University Library says that 70% of the library’s collection now is e-books, but he still believes that good books are worth reading slowly and fully. Professor Lin from Shanghai Normal University agrees that the AI age calls for deeper and wider reading. “Though AI is good at searching for and copying information, it cannot match human creativity,” he says. 6．How does the writer start Paragraph 1? A．By telling stories. B．By asking questions. C．By using numbers. D．By giving examples. 7．What can we learn from Professor Lin’s words? A．AI can help us read fully. B．We should read good books. C．AI cannot match our creativity. D．We should not read e-books. 8．What can be a proper title (标题) for the text? A．Deep reading in the AI age B．E-books in modern libraries C．Searching methods on the Internet D．AI tools for book summaries 七、短文填空 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 How Technology Helps Emperor Penguins With the development of science and technology, we have learned a lot about animals. Emperor penguins can grow up to 1.2 meters tall, and they are the 1 (large) of all the penguin kinds. In 2022, they were listed as endangered animals because the Antarctic sea ice that they live 2 is becoming smaller and smaller. Now scientists are using high technology to follow them and learn more about how 3 (protect) them. One of the 4 (way) researchers are able to do this is by looking at pictures taken by satellites above the Earth. Large groups of emperor penguins can be seen from space. When scientists first started using satellites to look at the penguins, there were only 28 groups. So far, scientists 5 (discover) 66 groups. Even using satellites, it is so difficult to count how many penguins live in different groups. Scientists can improve population estimates (估计) by watching the area’s weather 6 (careful). Measuring the wind speed and temperature can help predict if the penguins gather closely together or spread apart across the ice. If scientists know 7 the weather was like when the pictures were taken, they can estimate how many penguins are pictured. Scientists can also watch penguins’ movements by giving 8 (they) special electronic tags. A scanner 9 (carry) by a robot, and it can read information on the tags. The robot also uses AI to recognize the penguins. It moves very slowly so that it doesn’t make the birds stressed. Daniel, one of the penguin researchers, hopes the technology 10 (lead) us to a “golden age of research”. Thanks to technology, we are seeing more things that no one has ever seen before. 一、单词默写。 【答案】1. narrow 2.convenient 3.villager 4.miracle 5.support 6.product 7.host 8.result 9.determined 10.digital 二、词组默写。 【答案】1. convenient for 2.feed on 3.move to 4. below freezing 5.a group of 6.be known as 7.work together 8.be covered with 9.with support from 10.man-made forest 11.be determined to do 12. improve the environment 三、单词拼写 A.根据汉语提示完成单词 【答案】1. narrow 2.convenient 3.villager 4.miracle 5.support B. 根据句意及首字母完成单词。 【答案】6. product 7.host 8. results 9. determined 10. wide 四、A.根据汉语完成句子 【答案】1.made it convenient for 2. feed on 3. online physical form 4. below freezing 5.
