W：There is a method you can try.Every time you make coffee，dry the leftover coffee grounds and keep them in small bowls，then place the bowls in the kitchen. 听力试题 What are the speakers talking about？ A．How to fry fish.　 B．How to make coffee.　　 C．How to remove a bad smell. 策略应用　本题用到归纳总结和抓取关键词的方式。根据对话内容可知，他们在讨论如何去除异味，关键词为unpleasant smell stays，a method you can try，由此判断答案选 C。干扰项 A 中的“fry fish”和 B 中的“make coffee”均在材料中有所提及，属于“以偏概全”的干扰方式，有较强的干扰性。这就要求我们抓住对话的主线，而不要过于注重细枝末节。 返回 语基讲练　提能力 返回 Ⅰ. 核心词汇练全 enable vt.使可能，使发生(able adj.有能力的；ability n．能力；才能) enable sb to do sth　 使某人能做某事 be able to do sth 能够做某事，有能力做某事 have an ability to do sth 有做某事的能力　　 归 纳 1 (1)In the past few decades，learning a foreign language ___________(enable) people to communicate with others from different cultures.

As head of the team，I encourage the development of new technologies to maintain and protect important archaeological(考古的) findings.Right now，I am working in the field of Pompeii，an ancient Roman city which was destroyed and buried under 13 to 20 feet of ash and small rocks during a volcanic eruption in 79 AD.With the help of a robot，I try to carefully rebuild the city’s 2，000-year-old broken frescoes(壁画).The project is called RePAIR. There are thousands of fresco pieces in Pompeii，and it was nearly impossible for a human to reconstruct all the irregular pieces into big，meaningful paintings in the past.Technology now allows us to do it—the robot we use is running by artificial intelligence (AI).As it examines a piece，it searches a database for a match，and then sends the data back to its hands to fit matching pieces together，saving a lot of hours.Its soft human-like arms and hands allow it to hold and examine the easily broken pieces without damaging them.The technology is likely to allow many museums around the world to reconstruct large-scale broken frescoes or similar objects in the future. In RePAIR，I’m studying the hyperspectral(高光谱的) images of the fresco pieces in storage and comparing them with the paintings on the walls of the House of the Painters at Work，part of a building in Pompeii.By comparing the resemblances in the images，we will be able to work out whether the broken pieces were from the same wall. I studied history and archaeology in college.Archaeology helps us understand where we come from，and technology enriches that exploration.I’m glad I’m a translator of the two worlds.My mind runs wild when I think about the exciting Roman life that we are still missing because Pompeii’s frescoes were damaged and haven’t been rebuilt. 语篇解读　 本文是一篇记叙文。文章主要讲述了作者借助机器人复原庞贝古城破碎的壁画的故事。 1．What is the author mainly responsible for now？ A．Designing robots used for archaeology. B．Reporting on recent studies of historical ruins. C．Repairing the damaged archaeological findings. D．Discovering ancient cities hidden under the ground. √ 细节理解题。根据第二段中“Right now，I am working in the field of Pompeii...With the help of a robot，I try to carefully rebuild the city’s 2，000-year-old broken frescoes(壁画).”可知，作者现在正在机器人的帮助下，试图仔细地重建庞贝古城的有2 000年历史的破碎壁画。即作者现在负责修复损坏的考古发现。故选 C。 2．What is mentioned about the robot used in the project？ A．It doesn’t need human operators. B．It may cause further damage to artworks. C．It has already been widely used in museums. D．It takes more time to examine the artworks. √ 细节理解题。根据第三段中“Technology now allows us to do it—the robot we use is running by artificial intelligence(AI).”可知，重建项目中使用的机器人是由人工智能运行的，即机器人不需要人类来运行。故选 A。 3．What does the underlined word“resemblances” in Paragraph 4 mean？ A．Mistakes. B．Similarities. C．Damages. D．Documents. √ 词义猜测题。根据画线词所在句及上文可知，作者需要把储存的壁画作品的高光谱图像和庞贝的一座建筑的墙壁上的画作进行比较，进而确定碎片是否来自同一面墙。由此可推知，这里指通过图像比较，发现两者的相似之处。故选 B。 4．How does the author find her work in RePAIR？ A．Dangerous. B．Relaxing. C．Meaningful. D．Successful. √ 推理判断题。根据最后一段中“Archaeology helps us understand where we come from，and technology enriches that exploration.I’m glad I’m a translator of the two worlds.”可知，作者很享受自己所从事的工作，即作者感觉自己的工作是有意义的。故选C。 B (2024·安徽江南十校高一联考) The rise of digital technology has completely changed the way students live their lives.From the way they connect with each other to the way they learn，digital technology has become a necessary part of campus life.Then how has digital technology changed students’ campus life？ On the one hand，the use of social media has made it easier for students to keep in touch with their peers off campus.Some social platforms have become popular among students，allowing them to share their daily lives，engage in online conversations，and form virtual communities.Meanwhile，digital technology has also changed the way students communicate with their instructors.With email and online chat platforms，students can easily contact their teachers for homework，grades，and course content.This has improved communication between students and faculty，leading to a better learning experience. On the other hand，digital technology has also changed the way students learn.With online courses and virtual classrooms，students can access a variety of courses from the comfort of their own homes.This has opened up opportunities for students to follow their passions and interests outside of their majors.Actually，it has made it easier to improve and join in multiple campus events.Students can easily create online campaigns to promote events，organise events using online calendars，and even stream events live over the Internet.This has made it possible for more students to get involved and join in various campus events. Another benefit which is often ignored is its positive effect on their mental health.With online resources，such as anxiety apps and depression support groups，students can deal with stress and anxiety.They can ask for help when in need，as online services are available 24/7. Digital technology has changed campus life in many ways.While digital technology has brought many benefits，it has also raised concerns about its bad impact on student life. 语篇解读　本文是一篇议论文，主要讨论了随着数字技术的普及，学生的校园生活、交流方式以及学习方式也在随之改变。 5．What does the author describe at the beginning of the text？ A．Types of campus life.　　　 B．Changes in social life. C．Learning ways of students. D．Popularity of digital technology. √ 细节理解题。作者在文章开头说到数字技术已经成为校园生活的必要组成部分，即数字技术的普及这一现象。故选D 项。 6．What can students do when they use social media according to Paragraph 2？ A．Build different social media platforms. B．Contact classmates in class. C．Communicate with teachers online. D．Form common communities. √ 细节理解题。根据第二段中的“Meanwhile，digital technology has also changed the way students communicate with their instructors.With email and online chat platforms...content.”可知，数字技术也改变了学生与老师之间的交流方式，学生使用社交媒体可以轻松地和老师在线交流。故选C项。 7．Why can digital technology improve campus events？ A．It stresses the importance of campus events. B．It improves ways students organise events. C．It lights the passions and confidence of students. D．It encourages more contact with school teachers. √ 细节理解题。根据第三段中的“Students can easily create online campaigns to promote events，organise events using online calendars，and even stream events live over the Internet.”可知，学生可以轻松地创建在线活动来进行活动宣传，利用在线日历组织活动，还可以通过因特网直播活动。由此可知，数字技术通过改变学生宣传及组织活动的方式使得校园活动被推广。故选 B项。 8．What will be possibly discussed in the paragraph that follows？ A．The hidden risks of digital technology. B．The reasons for the development of digital tools. C．How campuses improve diverse digital practices. D．How we can avoid being addicted to digital technology. √ 推理判断题。根据最后一段中的“While digital technology has brought many benefits，it has also raised concerns about its bad impact on student life.”可知，数字技术带来好处的同时，也引发了人们对其对学生生活的负面影响的担忧，由此推测下一段可能讨论数字技术存在的潜在风险。故选 A 项。 Ⅳ.阅读七选五(共5小题；每小题2.5分，满分12.5分) (2024·广东佛山高一期末) How would you feel if moving to a new town meant losing track of your friends？ What if the only way of getting news from far away friends was writing letters that took ages to be delivered？ 1( ) Thanks to progress in technology，how we make friends and communicate with them has changed significantly.
