They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 14 One example is “keyhole surgery”, or minimally invasive （微创） surgery, which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient. But in June 2022, surgeon James Ansell used 3D glasses and two joysticks （操纵杆） to control four robotic arms to perform a procedure to remove a cancerous tumor （肿瘤）. “My colleague said...that . .this feels like cheating,” Ansell said to The Guardian. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Another area of surgery that has had major technological breakthroughs in recent years is telesurgery. Telesurgery, or remote surgery, is the use of technology that allows a surgeon to perform a procedure on a patient not in the same physical location. Normally, telesurgery relies on a wired connection due to concerns of harming the patient if a wireless connection should drop during surgery, but China made several advancements in wireless telesurgery based on 5G technology. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 China achieved the first 5G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing, a distance totaling nearly 3,000 kilometers, reported CGTN. More recently, a team of surgeons at the Hainan Eye Hospital successfully completed remote micron-level eye surgery via a 5G robot on rabbits located at the Sun Yat-sen University in Guangzhou, reported China Daily. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Some people even believe that robotic systems, combined with AI, could one day surpass （超过） human surgeons. But given current technological limitations and the high costs of these robots, the complete robot takeover of surgery may still be a while off. 【解题导语】 本文是一篇说明文。文章介绍了医疗机器人技术的进步。机器人工具在手术实践中引起了巨大的变化，它们大大减轻了外科医生通常承受的压力和体力要求，并使某些手术成为可能。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 1.What does the underlined part in paragraph 2 indicate?( ) A.The procedure may be illegal. B.The procedure may be difficult to control. C.The procedure may cheat the patient. D.The procedure may be conducted unknowingly. 解析：句意猜测题。根据第二段第一句和第二句可知，使用3D眼镜和两个操纵杆控制四个机械臂来进行切除癌症肿瘤的手术，大大减轻了外科医生通常承受的压力和体力要求，使手术在不知不觉中进行。因此“this feels like cheating”表示手术在不知不觉中进行。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 19 2.What significant achievement did China make in the field of telesurgery?( ) A.Removing a cancerous tumor using 3D glasses. B.Achieving remote surgery using a wired connection. C.Doing the first 5G-based eye remote operation on humans. D.Performing the first wireless brain surgery with 5G technology. 解析：细节理解题。根据第五段第一句可知，在远程外科领域，中国取得了首次使用5G技术进行无线脑部手术的成就。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 20 3.What can we infer about robots in the medical field according to the passage?( ) A.They still need further development. B.They have been widely adopted. C.They are currently in high demand. D.They have surpassed human surgeons. 解析：推理判断题。根据最后一段最后一句可推知，使用机器人完全接管手术还需要机器人进一步发展。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 21 4.What is the passage mainly about?( ) A.The benefits of robotic surgery. B.The future of robotic surgery. C.The advancements in medical robotics.

Applications for advanced driver assistance systems （ADAS） will replace the 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 23 average human reaction time, lowering it from 1.6 seconds to just 0.5 seconds, saving countless lives in the process. The driverless future of autonomous vehicles （AV） is set to transform society by reinventing （重塑） the transportation industry and changing consumer behaviors forever. Yet, the share of consumers who support government regulation of fully self-driving cars has declined by 15% over the past year, and trust in the safety of autonomous vehicles is down 5%. To address these ongoing safety concerns, more must be done. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Autonomous vehicles should not be regulated by the same rules that govern standard passenger vehicles because those regulations do not address the unique safety challenges for AVs. To address these concerns, the industry will need to continue building public trust through the improved performance of AV systems, especially in controlled environments. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 Reaching a totally hands-off and eyes-off autonomous driving experience will require a range of next-generation technologies that are still being developed. Automakers will continue to increase the safety of autonomous vehicles by applying new technologies such as artificial intelligence and machine learning to improve the performance of sensors that use radio and light waves to help detect road users in all weather conditions. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 The technical brain of an AV system relies on software systems that actively protect passengers. As this market grows, costs will steadily fall for these new sensors and high-performance computers, just as safety standards continue to progress around the country and the world. To help build confidence in AVs, the industry will need to generate a common set of testing standards, similar to crash safety standards, that AV developers can evaluate their systems against. 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 As autonomous driving evolves, the road to a driverless future still holds many twists and turns ahead. It should be an exciting and wild ride for years to come as the auto industry reinvents itself with ever-increasing levels of automation. 【解题导语】 本文是一篇说明文。文章讨论了自动驾驶汽车的未来，强调了其在提高交通安全、重塑交通行业和改变消费者行为方面的潜力，同时指出了公众对其安全性的担忧以及如何建立公众信任。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 5.What make consumers still hesitant about the application of AVs?( ) A.Costly operating systems.

I was full of high expectations, believing that becoming an author was merely a matter of putting my thoughts onto paper, sending the works to a publisher, and waiting for fame to come. Nevertheless, what came was total disappointment. I wrote to the famous children's author Lloyd Alexander, describing my fruitless year-long effort at publication and asking him for direction. To my delight, he answered:“Advice is 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 always very easy to give, but it's very hard to make it specific and meaningful since we all have to work in our own ways. When you mention that you've been writing for a year without being published, I hasten to tell you that I wrote seven times that long without being published! So, perhaps one piece of advice is: patience.” I was encouraged by the idea that a well-regarded writer would take the time to offer a bit of advice to an overconfident teen. But Mr. Alexander was not a singular case （个别现象）.I continued to 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 reach out to writers and, truth to tell, I didn't always receive a reply. But when I did get one, the content was often filled with consideration and even, at times, affection. I think of the American poet William Stafford, who replied to me from Lake Oswego, Oregon. We actually had an ongoing correspondence （通信） for a while. I wrote to him asking if he would be so kind as to autograph （签名） one of his books for me. His reply brought an immediate smile to my face: “I am eagerly ready to autograph and return a book—it makes me feel like an author.” 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 【解题导语】 本文是一篇记叙文。文章讲述了作者在成为作家的路上,给一些著名的作家写信,他们的建议和反馈让作者受益良多的故事。 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 37 9.What happened to the author when he was 18?( ) A.He won fame as a young writer. B.He was forced to give up writing. C.He met a famous children's author. D.He failed to get his works published. 解析：推理判断题。根据第二段中的“It all started in my 18th year...what came was total disappointment.”可知,在作者18岁的时候,他的作品未能出版。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 38 10.What advice did Lloyd Alexander offer to the author?( ) A.Being independent of others. B.Making decisions without hesitation. C.Keeping on trying and being patient. D.Regarding every piece of writing as meaningful. 解析：细节理解题。根据第二段中的“When you mention...perhaps one piece of advice is: patience.”可知,劳埃德·亚历山大建议作者坚持尝试,保持耐心。 √ 课后巩固 多维提能 1 2 3 4 5 6 7 8 9 10 11 12 39 11.What did the author think of William Stafford?( ) A.He hated to reply to a letter.
