《2025年高考模拟试题汇编高中英语》

D
Glasgow University researchers have created a laser(激光) camera using AI and quantum technologies to remotely detect a person's heartbeat, potentially changing health monitoring. Professor Faccio imagines various applications, such as setting up this technology in shopping malls or fixing laser heart monitors in homes. These monitors could be part of an extensive system tracking different health aspects, such as blood pressure and slight changes in movement, indicating early signs of conditions like Alzheimer's.
Monitoring a person's heartbeat from a distance holds significant value, as it can detect irregularities like abnormal heart rates, providing crucial warnings of potential heart issues. In contrast to the traditional use of stethoscopes(听诊器), this system overcomes limitations associated with proper stethoscope usage, such as the need for training and the potential reduction of heartbeat signals.
The system developed by Faccio and his team involves high - speed cameras which can record images at speeds of 2 000 frames per second. A laser beam is shone on to the skin of a person's throat and the reflections are used to measure exactly how much their skin is rising and falling as their main artery(动脉) expands and contracts as blood is forced through it. These changes involve movements of only a few billionths of a metre.
Such acuity is striking, though on its own the tracking of these tiny changes would not be enough to track a heartbeat. Other much larger movements occur on a person's chest—from their breathing, for example—which would flood signals from their heartbeat.
“That is where AI comes in,” Faccio said. “We use advanced computing systems to separate out everything except the vibrations caused by a person's heartbeat. We know the frequency range of the human heartbeat, and the AI focuses on that. The prime use of this technology—which we hope to have ready next year—will be to measure heartbeats easily and quickly outside hospitals. The benefits could be considerable.”
32.What can the laser camera be used for?
A. Improving the usage of stethoscope.
B. Measuring blood pressure remotely.

B. Where it is used.
C. Whom it benefits.
D. What it is composed of.
34.Which is closest in meaning to “acuity” in Paragraph 4?
A. Consistency.
B. Complexity.
C. Sensitivity.
D. Intensity.
35.What role does AI play in this system?
A. To measure skin movements.
B. To recognize heartbeat vibrations.
C. To record images at high speeds.
D. To shine a laser beam on the skin.

答案： 32.D　细节理解题
[定位句]Glasgow University researchers have created a laser(激光) camera using AI and quantum technologies to remotely detect a person's heartbeat, potentially changing health monitoring. (第一段第一句)
译文:格拉斯哥大学的研究人员利用人工智能和量子技术发明了一种激光相机来远程检测人的心跳，这可能会改变健康监测。
[解析]该题问的是这种激光相机的用途是什么。根据定位句可知，这种激光相机可以远程检测人的心跳。故选D。
33.A　段落大意题
[解析]通读第三段可知,Faccio和他的团队研发的这个系统包括高速摄像机,可以以每秒2000帧的速度记录图像。激光束照射在人喉咙的皮肤上,其反射光被用来准确测量当血液被迫使通过主动脉时，他们的皮肤在主动脉扩张和收缩时的升降幅度。这些变化只涉及几十亿分之一米的运动。由此可推知，本段主要讲述了这个系统的工作原理。故选A。
34.C　词义猜测题
[解析]根据第四段第一句中的“Such acuity is striking”可将答案定位到上一段。根据第三段第一句“The system developed by Faccio and his team involves high - speed cameras which can record images at speeds of 2 000 frames per second. ”可知，Faccio和他的团队研发的这个系统包括高速摄像机，可以以每秒2 000帧的速度记录图像；再结合第三段最后一句“These changes involve movements of only a few billionths of a metre. ”可知，这个系统记录的变化只涉及几十亿分之一米的运动。由此可知，这个系统的敏度是非同寻常的。由此可推知，画线词acuity应意为“敏锐，敏度”，和C项意思相近。故选C。
长难句分析：Monitoring a person's heartbeat from a distance holds significant value, as it can detect irregularities like abnormal heart rates, providing crucial warnings of potential heart issues. (第二段第一句) 分析：本句是一个主从复合句。as引导原因状语从句，其中“providing... heart issues”是现在分词短语作结果状语。译文：远距离监测一个人的心跳具有重要的价值，因为它可以检测到诸如心率异常这样的不规则现象，就潜在的心脏问题提出重要的警示。
重点词汇与短语：detect v.探测，查明；application n.应用，申请；indicate v.显示，表明；limitation n.限制，限定；set up 安装好，设立；in contrast to 与……形成对照
一词多义：fix(第一段第二句)
(1)v.安装·Video cameras are fixed everywhere from shops to restaurants.从商场到饭店，到处都安装了摄像头。
(2)n.处理，解决(问题等)·This way, you will be able to fix the problem before your home becomes flooded or catches fire.这样，你就能在你的房子被水淹或着火之前解决问题。
(3)v.目不转睛地看·The boy lay on the ground and fixed his eyes on the ceiling. 男孩躺在地上，眼睛盯着天花板。
(4)v.修理，维修·The repairman is able to fix his car but it will take him a long time to get the car to work well again. 修理工能修好他的汽车，但要使汽车重新运转起来要花很长时间。
(5)v.确定·He's going to fix a time when I can see him. 他会确定一个我和他会面的时间。
35.B细节理解题
[定位句]We use advanced computing systems to separate out everything except the vibrations caused by a person's heartbeat. We know the frequency range of the human heartbeat, and the AI focuses on that.(最后一段第二、三句)
译文:我们使用先进的计算系统分离出除了由人的心跳引起的震动之外的所有东西。我们知道人类心跳的频率范围，而人工智能专注于此。
[解析]该题问的是人工智能在这个系统中起什么作用。根据定位句可知，人工智能在这个系统中的作用是识别心跳(引起)的震动。故选B。
