Using language, talk about scientific experiences. Three, listen to the conversation and see if your answers for activity too are correct, then write down the letters a to e for the photos in the order that you hear them described. Oh, i'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better. Much Better. thanks. But how was . IT wonderful? I especially liked an area of the museum called light games. IT was really cool. They had a hall of mirrors where I could see myself reflected thousands of times. A whole of mirrors can be a lot of fun. What else did they have? Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny, bright lights moving around on IT. You'll never guess what those bright lies were. Come on. tell me they were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights. But there was another thing I liked Better. I stood in front of a White light, and IT costs different shadows of me in every . color of the rainbow. I wish I had been there. Tell me more. Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then instead of playing the sounds of a piano, IT played the voices of classical singers. Then they had a giant dish. And when you spoke into IT, IT reflected the sound back and made IT louder. You could use IT to speak in a whisper to someone seventeen meters away. IT all sounds so cool. I wish I could have one. You I know, but we can go together this weekend. I'd love to go there again. That sounds like a great idea. Period 3 Listening and Speaking Unit 1 Science and scientists 1.What’s the probable relationship between the two speakers? A.Friends. B.Strangers. C.Fellow-travelers.

Friedman，a top scientist，noted that the amount of CO2 contained in the project is extremely small compared to the overall amount that needs to removed.“But that’s how it starts，” he said. Heirloom’s chief，Samala，explained the process，which involves limestone(石灰岩).Heirloom heats crushed limestone，which releases the CO2 it contains.Then the limestone can capture more gas in the same way a sponge takes in water.The company then repeats the process multiple times to collect more of the polluting gas. Building is a very polluting industry.Concrete alone accounts for eight per cent of the world’s CO2 production.CarbonCure mixes the gas with concrete’s ingredients，which makes a stronger final product.The concrete does not even require cement(水泥)，a usual additive to concrete. This also helps in the fight against CO2 as cement production requires a lot of energy.The leader of CarbonCure said the new processes would reduce concrete’s carbon production by about five per cent. The technology is promising but would require widespread use to make a real difference.Samala guessed it would cost hundreds of millions or billions of dollars to establish enough centres and systems.He thinks companies that work in other pollution-reducing areas will support carbon capture projects like this. Khan，a science director at Carbon180，a group that works to reduce carbon pollution，called the technology “a really thoughtful way to get around the current bottleneck of storage” for captured carbon. 1.What do the two companies do? A.They turn CO2 into concrete. B.They use concrete to trap CO2. C.They jointly produce concrete. D.They sell CO2 capture systems. √ 细节理解题。根据第一段“Two companies...both working on CO2 capture systems，are working together to collect CO2 and put it into new concrete.”可知，这两家公司正在合作收集二氧化碳并将其注入新的混凝土中，即他们在使用混凝土来捕获二氧化碳。故选B。 解析 2.What does Friedman think of the project? A.It’s a big deal. B.It’s a dead end. C.It’s a good start. D.It’s a heavy burden. √ 观点态度题。根据第三段“Friedman...‘But that’s how it starts，’ he said.”可知，弗里德曼认为这个项目是一个好的开始。故选C。 解析 3.What’s paragraph 4 mainly about? A.How CO2 is captured. B.Why CO2 is captured. C.How limestone is used. D.Why limestone is used. √ 段落大意题。通读全段，并结合第一句中“Heirloom’s chief，Samala，explained the process”可知，第四段主要讲二氧化碳是如何被捕获的。故选A。 解析 4.What can be learned about the project? A.It cost a large sum of money. B.It caused a real bottleneck. C.It made a real difference. D.It may enjoy popularity. √ 推理判断题。根据倒数第二段中“Samala...He thinks companies that work in other pollution-reducing areas will support carbon capture projects like this.”和最后一段“Khan...called the technology ‘a really thoughtful way to get around the current bottleneck of storage’ for captured carbon.”可推知，这个项目可能会受欢迎。故选D。 解析 B (2025·浙江宁波高二上期末) Three-dimensional printing，a technology that creates objects layer by layer，has revolutionized(变革) the way we make things.Recently，a group of Chinese scientists took things a step further by using this technology to create realistic replicas(复制品) of human organs. 语篇解读　这是一篇说明文。文章主要介绍一组中国科学家利用三维打印技术制造出了逼真的人体器官复制品的过程和意义。 Previously，it was challenging to create a single material that could print different human organs due to their complexity.The research team from Chinese Academy of Sciences started by using hydrogel(水凝胶)，a soft gel-like material as the main ingredient. Human organs have various textures(质地)，with our brains being the softest.To replicate the hardness of materials like bone，the researchers added metallic elements to the hydrogel and adjusted their ratio(比例) to create the texture of each organ.Besides，to make sure the printing results are correct，the team used light-curing(光固化) technology in the 3D printing process. A special lamp was placed under the printing machine，causing the gel to become solid right after it was printed. According to the team’s paper published in the journal Advanced Functional Materials，they are able to produce organ models including the brain，lungs，and intestines(肠).These 3D printed organ models are essential for medical researches，such as testing medical equipment and demonstrating surgeries.Compared to live organs and animal models，they are also ethically(伦理上) acceptable since they are printed artificially.They can help researchers develop new treatments more efficiently，due to their lower relative cost， commented the Alliance of Advanced Biomedical Engineering website.However，this method is still developing，and experts are hoping it will be used in the medical field within a decade，according to CNN. 5.What was the main challenge in printing human organs? A.The complexity of human organs. B.The various textures of human organs. C.The difficulty in creating proper materials. D.The lack of appropriate printing technology. √ 细节理解题。根据第二段中“Previously，it was challenging to create a single material that could print different human organs due to their complexity.”可知，打印人体器官的主要挑战是人体器官的复杂性。故选A。 解析 6.How did the research team ensure the accuracy of the printing results? A.By controlling the number of metallic elements. B.By using light-curing technology before printing. C.By solidifying the gel immediately after printing. D.By putting a special lamp on the printing machine. √ 细节理解题。根据第三段中“Besides，to make sure the printing results are correct，the team used light-curing(光固化) technology in the 3D printing process.A special lamp was placed under the printing machine，causing the gel to become solid right after it was printed.”可知，研究团队通过在打印后立即固化凝胶来保证打印结果的准确性。故选C。 解析 7.What can we infer from the last paragraph? A.This technology is still in the period of theory. B.3D printed organs are of great medical significance. C.The printed organs are more effective in the treatment. D.Live organs and animal models are more acceptable ethically. √ 推理判断题。根据最后一段中“These 3D printed organ models are essential for medical researches，such as testing medical equipment and demonstrating surgeries.”可知，3D打印器官具有重要的医学意义。故选B。 解析 8.What is the best title for the text? A.The Power of 3D Printing B.Printing the Body Parts C.Revolutionary Technology D.Finding New Materials for Organs √ 标题归纳题。通读全文，尤其是由第一段中“Recently，a group of Chinese scientists took things a step further by using this technology to create realistic replicas(复制品) of human organs.”可知，文章主要介绍一组中国科学家利用三维打印技术制造出了逼真的人体器官复制品的过程和意义。选项B“Printing the Body Parts(打印身体部位)”符合题意。故选B。 解析 (2024·河北石家庄高二下期中)
