This so-called digital twin will be a working model of your body that can be shown on a physician's comput- er screen. Updated with your latest vital signs, it will assist the doctor to make an accurate diagnosis(诊断) and provide personalized treatments for the patients. No matter how unreal this might seem, the researchers at Queen Mary University of London (QMUL) al- ready use computer simulations(模拟) of the hearts of patients to test different treatments for a heart disor- der. It would be far too dangerous to experiment this way on someone's real heart. Digital twins are starting to be seen everywhere. They can not only monitor the health of jet engines on air- 第1讲　描述运动的基本概念 liners, but also help carmakers spend fewer years on the development of new models by simulating test drives and crashes. All this is being powered by recent progress in AI, which gives twins the ability to make predictions about their physical counterparts(对应的事物), and adjust themselves based on new information. Digital twins make it easier for humans to solve challenging problems, allowing people to have a look into the future. For businesses, this should mean better designs and operations. For society, the promise is also fascinating: personalized health care, and ways to prevent the earth from environmental disasters. Could these virtual twins go out of control? They might if they are programmed badly, or hacked into. Digi- tal twins will take in a substantial amount of data, some of it wrong and much of it raising concerns about privacy. Yet those risks are a natural part of technological progress. The appearance of the digital mirror world will raise new questions, but its potential benefits are already easy to see. 第1讲　描述运动的基本概念 1.Which of the following best describes a digital twin? A.A toy model. B.A virtual copy. C.A video game. D.A medical database. 第1讲　描述运动的基本概念 2.Why do researchers at QMUL use computer simulations of hearts? A.To reduce the time of the heart operation. B.To use real hearts much more conveniently. C.To help increase the patients' recovery rates. D.To avoid the danger of experimenting on real hearts. 第1讲　描述运动的基本概念 3.How does AI contribute to the development of digital twins? A.It increases the efficiency of simulations through data analysis. B.It creates accurate digital copies for medical and industrial use. C.It enables digital twins to predict results and adapt on their own. D.It improves virtual models by adding real-time monitoring features. 第1讲　描述运动的基本概念 4.What is the author's overall attitude toward the development of digital twins? A.Clearly critical. B.Strongly supportive. C.Deeply ambiguous. D.Cautiously optimistic. 第1讲　描述运动的基本概念 语篇解读    本文是一篇说明文。文章主要介绍了数字孪生技术的概念、应用、优势和潜在风险。 【高频词汇】    1.accompany v.陪伴;为……伴奏 2.accurate adj.准确的;精确的    3.simulate v.模拟;假装 4.adjust v.调整;适应    5.potential adj.潜在的 n.潜力;可能性 【差距词汇】　hack v.非法侵入(他人的计算机系统) 解析 1.B　细节理解题。根据第一段中的“This so-called digital twin will be a working model of your body that can be shown on a physician's computer screen.”可知,数字孪生体是虚拟的复制品。故选B。 第1讲　描述运动的基本概念 2.D　细节理解题。根据第二段中的“It would be far too dangerous to experiment this way on someone's real heart.”可知,研究人员使用计算机模拟心脏是为了避免在真实心脏上进行实验的危险。故选D。 3.C　细节理解题。根据第三段中的“All this is being powered by recent progress in AI, which gives twins the ability to make predictions about their physical counterparts, and adjust themselves based on new information.”可知,人工智能使数字孪生能够预测结果并自行调整。故选C。 4.D　推理判断题。根据最后一段中的“Yet those risks are a natural part of technological progress.
