Night Vision Goggle Training Technologies and Situational Awareness

详解美军增强现实眼镜：不止拐弯枪，中国何时能装备？近日，美军花费219亿从微软采购12万个集成视觉增强系统（IVAS）头盔，当然这其实不是第一次采购这种装备了。

2019年11月，美军花费4.79亿美元采购了10万个增强现实眼镜，这批的单价是每个4790美元，折合约3.1万人民币，与其民用版HoloLens2眼镜的价格差不多，而IVAS如果折算到每个单价，则高达18.25万美元，折合约119万人民币。

因此，IVAS除了包括了头盔的成本，估计还有大量的软件费用。

确实，IVAS能做的事情不少，不止巷战辅助这么简单。

巷战辅助美军曾演示过IVAS的功能，其最大的特点是现实环境中显示一些虚拟的图像，包括其它设备传输来的数据。

因此，IVAS上可以直接显示瞄准镜通过蓝牙传来的目标数据，所以许多网友感兴趣的拐弯枪可以用这个方式实现。

拐弯美军在公开演示中还展示过，IVAS可以在视野的最上方加上方向指示，在看到的真实景物中叠加显示电子地图。

方向和地图能把夜视仪/热成像仪的视野扩大到180度，还能同时标注同样佩戴IVAS的队友位置，这种标注能穿过地形的阻挡。

队友位置另外，美军还在尝试在坦克和装甲车上安装摄像装置，把车辆周围的环境拍摄下来，传输给车组成员。

如此一来，车组可以在不露头的情况下观察周围环境，这降低了危险。

而且，很多玩过坦克和战机游戏的网友应该体会过的是，以第三人称视角操作坦克和战机比锁死座舱/战斗室视角的游戏简单多了。

也许玩过射击游戏的网友对此感到非常熟悉，没错，许多游戏里有这样的设定，目的是简化操作，让更多的玩家能更快地熟悉游戏。

而在IVAS发明之前，军队在真正的演习和作战中是无法体验到这样的便利的，是这种装备让军人也能体会到如此的便利，从而更高效地作战。

当然对于在中东以及阿富汗执行任务的美军来说，IVAS的一些功能恐怕更会受到他们的欢迎，比如投影出3D结构的地图观察局势。

3D地图又比如美国大兵根本看不懂当地文字或者只会一点点，但眼镜中可以直接显示各种路牌和招牌的翻译，或许还有指挥官以及其他部队标注的信息。

高二现代科技英语阅读理解25题1<背景文章>Artificial intelligence (AI) has been making remarkable strides in the medical field in recent years. AI - powered systems are being increasingly utilized in various aspects of healthcare, bringing about significant improvements and new possibilities.In the area of disease diagnosis, AI algorithms can analyze vast amounts of medical data, such as patient symptoms, medical histories, and test results. For example, deep - learning models can detect early signs of diseases like cancer by examining medical images, such as X - rays, CT scans, and MRIs, with a high level of accuracy. These models can identify patterns and anomalies that might be overlooked by human doctors, thus enabling earlier and more precise diagnosis.When it comes to drug development, AI also plays a crucial role. It can accelerate the process by predicting the effectiveness of potential drugs. AI - based platforms can simulate how different molecules will interact with the human body and target diseases. This helps pharmaceutical companies to screen a large number of compounds more efficiently, saving both time and resources. Instead of the traditional trial - and - error method which is time - consuming and costly, AI provides a more intelligent andtargeted approach to find promising drug candidates.Medical robots are another area where AI is making an impact. Robots equipped with AI can assist surgeons during operations. They can provide more precise movements and reduce the risk of human error. For instance, some surgical robots can perform minimally invasive surgeries with greater dexterity, resulting in smaller incisions, less pain for patients, and faster recovery times. Moreover, AI - driven robots can also be used for patient care, such as helping patients with mobility issues to move around or delivering medications in hospitals.In conclusion, the application of AI in the medical field is revolutionizing healthcare, offering better diagnosis, more efficient drug development, and improved patient care.1. What can AI algorithms do in disease diagnosis according to the article?A. Only analyze patient symptoms.B. Analyze limited medical data.C. Detect early signs of diseases accurately by examining medical images.D. Replace human doctors completely.答案：C。

physical chemistry class at The University of Michigan in1940.Jerome Karle was in his first year of doctoral work,and Isabella Lugoski was in her last year as an undergraduate(大学本科生),and they were laboratory partners.However,they didn't get along well at first.Isabella Lugoski looked back on the past,“I walked into the physical chemistry laboratory and there was a young man at the desk next to mine with his equipment all set up running his experiment.I didn't think I was very polite about my question.I asked him how he got there early and had everything all set up.He didn't like that.So we didn't talk to each other for a while.”Their relationship got going as they competed for the top grade in that course and they started to build connection because both of them were interested in chemistry.They married in1942.By1946,both of the Karles had earned doctorates in physical chemistry,and,after a period of time at The University of Chicago working on the Manhattan Project,they moved to Washington DC to join the United States Naval Research Laboratory.Each specialized in a different aspect of X-ray crystallography(晶体学): Jerome focused on developing equations(方程式)that could determine how atoms(原子)were arranged inside complex molecules,while Isabella ran practical experiments to test how well the equations worked.Working together,they created what is now called the direct method for determining molecular structures(分子结构),which has allowed scientists to effectively study and copy complex organic molecules to continue further study.Jerome Karle was awarded the Nobel Prize for Chemistry in1985.Although he was disappointed that the Nobel committee had ignored Isabella's contribution to that work,she was unfazed.At that point,she had already won more awards and prize money for her experimental work than he had.4.What did Isabella Lugoski do when she first met Jerome Karle?A.She blamed him for his being late.B.She set up all his equipment for him.C.She asked him a question impolitely.D.She observed his experiment silently.5.What made Jerome Karle and Isabella Lugoski become connected?A.Their common interest in chemistry.B.Their wonderful marriage

teamwork in science.C.How the Karles worked with others.D.Why the Karles won the Nobel Prize.7.Which of the following best explains the underlined word“unfazed” in the last paragraph?A.Generous.B.Touched.C.Shocked.D.Calm.C“For all the technological wonders of modern medicine,from gene editing to fetal(胎儿的)surgery,health care—with its fax machines and clipboards(写字夹板)—is often stubbornly old-fashioned.This outdated era is slowly drawing toa close as the industry catches up with the revolution of artificialintelligence(AI).And it should happen earlier,” argues Eric Topol,a heart doctor keen on digital medicine.Dr.Topol's vision of medicine's future is optimistic.He thinks AI will be particularly useful for repetitive tasks where errors arise easily,such as selecting images,examining heart traces for abnormal symptoms or recording doctors' words into patient records.In short,AI is set to save time,lives and money.Much of this is imaginary—but AI is already defeating people in a variety of narrow jobs for which it has been trained.Eventually it may be able to diagnose and treat a wider range of diseases.Even then,Dr.Topol thinks, humans would watch over the rules,rather than being replaced by them.The author's fear is that AI will be used to deepen the assembly line(流水线)culture of modern medicine.If it awards a“gift of time” to doctors,he argues that this additional benefit should be used to extend the time of consultations,rather than simply speeding through them more efficiently.The Hippocratic Oath holds that there is an art as well as a science to medicine,and that“warmth,sympathy and understanding may be more important than the surgeon's knife or the chemist's drug”.That is not just a cliché:the patients of sympathetic physicians have been shown to do better.As Dr.Topol says,it is hard to imagine that a robot could really replace a human doctor.Yet as the demand for health care goes beyond the supply of human carers,the future may involve consultations on smart phones and measurement monitored by chat robots.The considerately warmed stethoscope(听诊器),placed gently on a patient's back,may become history.8.According to the author,health care has been generally considered.A.to bring out many technological wondersB.to boost the sales of fax machines and clipboardsC.to be out of date and fail to keep up with modern timesD.to constantly catch up with new technological progress9.AI is set to save time,lives and money because it can.A.repeat doctors'words and instructionsB.correct doctors'errors and mistakesC.select doctors according to patients'demandsD.replace doctors'tasks in certain fields10.The underlined word“cliché” is closest in meaning to.A.an idea that is so often used that it becomes uninterestingB.an idea that is so interesting that it is often usedC.an effective rule that applies to medicine and doctorsD.a benefit to both doctors and patients11.It can be inferred from the passage that.A.AI will completely replace the jobs of doctorsB.doctors'sympathy and understanding should not be ignoredC.the application of AI will discourage the assemblyline cultureD.AI will bring warmth,sympathy and understanding to patientsDA new officer of the Huntington Park Police patrols(巡逻)local parks24 hours a day seven days a week.He doesn't need rest,coffee breaks,a salary or medical insurance,and that is because it is a Robocop.The main function of the Robocop is to scan and film the surroundings. Besides cameras with night vision that report360degrees,it also has a distress button which is located here,so if somebody needs assistance or wants to contact the communication center,he or she can do it by way of that distress button.There are people that are monitoring on the other end.This newest police employee is self-charging.It's easy to program it and make changes to the software if necessary.Its maintenance(维护)costs are roughly75thousand dollars a year.It travels the entire park.It is a programmed path,but the police are able to change the path and adapt it.The Robocop can record the license plates(车牌)of passing cars and check them against an online database of stolen cars.It can also help locate a lost iPhone because it is able to determine a smart phone's MAC address.The police can see from the robot if something wrong happens and then come and figure it out.The Robocop can't replace its human handlers.The whole goal is to give the police more time to do things machines can't do.The police have been having some concerns about the safety of parks and want an extra set of eyes that will help patrol a24/7.The Robocop's creators believe this model known as K5is best used for providing security at public places like hospitals,parking lots,parks and airports.So far,it seems to be working out just fine.12.What is the distress button used to do?A.Locate the Robocop.B.Serve as an alarm device.municate with visitors.D.Monitor the neighbourhood.13.Which of the following can best describe the Robocop?A.Helpful but dangerous.B.Intelligent but inexpensive.C.Tireless and multifunctional.D.Fashionable and good-looking.14.Why does the Robocop record the license plates of passing cars?A.To direct traffic.B.To build a database.C.To prevent accidents.D.To find lost cars.15.What can we infer about the Robocop in the last paragraph?A.It has limitation in use.B.It has been widely used.C.Its creators need more support.D.Its security is still under test.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项,选项中有两项为多余选项。

01 人与社会--科学与技术Passage 1（2024高三上·全国·专题练习）Natural disasters like earthquakes and storms can pull down buildings easily. It's difficult for the search and rescue teams (搜救队) to find those who are trapped (陷于困境) in the fallen buildings.But an unlikely assistant, mice, is being trained up to help out. The project started by Belgian APOPO, is planning to tie tiny, high-tech backpacks to mice to help search for survivors (幸存者).“Mice like to explore —and that is key for search and rescue.” said Donna Kean, a scientist and leader of the project.“ Besides, their small size and excellent sense of smell make them perfect for locating (定位) things in small spaces.”The mice are being trained in a basic environment at present. They must first locate the target (目标) person in an empty room, pull a switch that starts an alarm on their clothes, and then return home, where they are given a treat.For the next part of training, Kean said the team would create “disaster-similar areas”. Once the mice are confident in these areas, the project will move to Turkey for further preparation in more real environments. If that goes well, the mice would probably enter real- life situations.The mice are still in the early progress of training. And APOPO is working with the Eindhoven University of Technology to develop a backpack with a video camera, a two-way microphone, and a locating tool to help communicate with survivors. “Together with the backpack and the training, the mice are very useful for search and rescue,” said Kean. “Even if our mice find just one survivor, we would be happy toknow they have made a difference somewhere.”1．According to the passage, What’s the reason for mice to be chosen for search and rescue① Because their nature of exploring.② Because their small sizes.③ Because their ability to smell something.④ Because their perfect eyesight in the dark.A．①②③ B．①③④ C．②③④ D．①②④2．Which paragraph tells how the mice are trainedA．Paragraph 1. B．Paragraph 2.C．Paragraph 3. D．Paragraph 4.3．What can we learn from the passageA．Donna Kean is a survivor in an earthquake.B．The mice are being trained in real-life situations.C．APOPO scientists haven’t invented the high-tech backpack.D．The mice are often given a treat before they complete the task.4．What does Donna Kean think of the projectA．Nervous. B．Interesting.C．Hopeful. D．Impossible.【答案】1．A 2．D 3．C 4．C【导语】这是一篇说明文。
