Ⅲ. 新情境 (2024·天津河东区期末) 阅读理解 主题语境: 人与社会 语篇类型: 说明文 建议用时: 8
Have you ever lost something in a hard - to - reach space, like behind a couch or a cupboard? Wouldn't it be nice to just be able to squeeze (挤) in and out? New innovations in the field of robotics will soon be able to make this nice idea into a reality.
In a study published on Jan. 25 in the science journal Matter, engineers from the Chinese University of Hong Kong and Carnegie Mellon University in the US have developed small robots that can quickly change back and forth from liquid to solid states.
According to the website Mashable, the scientists were inspired by sea cucumbers (海参). They are able to change the stiffness (僵硬度) of their body or reduce the potential for physical damage. The robots in the study were made from gallium, a soft metal with a low melting point of 30°C. The scientists then used changes in the magnetic field to control the magnetic particles (粒子) inside the gallium material to provide heat. This heat then allowed the robots to change between solid and liquid states as well as to move around.
As the website Tech Xplore pointed out, other similar materials require external heat sources such as heat guns and electrical currents to induce (触发) a change of states; but now, the robots can use a heat source inside itself to change states independently.
During the robots' experimental trials, the scientists conducted a number of tests. These tests included having the robots melt into liquid and re - form to escape a prison - like cage. The robot is also able to build and repair hard - to - reach circuits (电路). The robots' ability to switch between states of matter allows for a number of possible uses and advancements in different fields, such as the biomedical and circuit assembly (组装) industries.
Still, in the words of senior author Carmel Majidi at Carnegie Mellon University, for now these are all just "proofs of concept" which show the abilities of these new kinds of robots.
1. What can we learn about the small robots?
A. Chinese and British scientists co - produced them.
B. Sea cucumbers provided inspiration for them.
C. They were made from a newly invented material.
D. They can switch between three states of matter.
2. How did scientists change the state of the robots?
A. By using heat guns.
B. By employing a heat source.
C. By using electrical currents.
D. By controlling the magnetic particles.
3. What is Paragraph 5 mainly about?
A. The features of the robots.
B. The limitations of the robots.
C. The applications of the robots.
D. The challenges of testing the robots.
4. What can be inferred about the robots from Majidi's words?
A. They have great market potential.
B. Their abilities are overstated.
C. More proof is needed for their abilities.
D. It will take more time for them to be widely used.

答案： Ⅲ. 语篇导读 本文是一篇说明文。文章主要介绍了可以转换形态的新型机器人。
1. B 细节理解题。根据第三段中的"According to the website Mashable, the scientists were inspired by sea cucumbers(海参)."可推知，关于小型机器人我们了解到的是海参为科学家们提供了灵感。故选B。
2. D 细节理解题。根据第三段最后两句可推知，科学家们通过控制磁性粒子来改变机器人的状态。故选D。
3. C 主旨大意题。根据第五段内容可知，在机器人的试验中，科学家们进行了许多测试。这些测试包括让机器人融化成液体，然后重新塑形以逃离监狱般的笼子。该机器人还能够构建和修复难以触及的电路。机器人在物质状态之间切换的能力在不同领域有许多可能的用途和发展，例如生物医学和电路组装行业。可知本段主要讲述这种机器人的应用。故选C。
4. D 推理判断题。根据最后一段可知，用第一作者卡内基梅隆大学的卡梅伦·马吉迪的话来说，目前这些都只是"概念证明"，用于展示这些新型机器人的能力。故可推知，机器人需要更多时间才能被广泛使用。故选D。
素养解读 本文围绕学习能力、语言能力和思维品质等学科素养展开。本文介绍一种利用磁场变换来控制磁性粒子从而改变状态的机器人，文中的词语很多是科学术语，尤其是文中长难句的理解对于提高学生的学习能力和语言能力有很大的帮助。另外文中谈到这种机器人在不同领域的使用，预测将来这种机器人还需要更多时间才能被广泛应用，这对提升学生探索科技的能力，培养学生创新思维，鼓励他们不断求知、不断尝试去开拓未来有一定的促进作用。
长难句分析 In a study published on Jan. 25 in the science journal Matter, engineers from the Chinese University of Hong Kong and Carnegie Mellon University in the US have developed small robots that can quickly change back and forth from liquid to solid states.
分析：本句中的published on Jan. 25 in the science journal Matter是过去分词短语作后置定语，修饰a study，句中的主语为engineers，have developed是主句的谓语，that引导定语从句修饰small robots。
译文：在1月25日发表在科学期刊《物质》上的一项研究中，来自香港中文大学和美国卡内基梅隆大学的工程师开发出了可以快速从液态到固态来回变化的小型机器人。
