If a patient knew their doctor was going to give them bad information during an upcoming appointment, they’d cancel immediately. Generative AI models such as ChatGPT, however, frequently make stuff up to cheat our eyes. So why would anyone want to use AI for medical purposes
Here’s the optimistic scenario(设想): not only do AI tools get trained on medical literature, but they also scan patient records and smartwatch data. Then, they produce personalized tips to each user, accurate enough to be helpful. The dystopian version: governments, insurance companies, and the medical enterprises push immature AI to cut costs, leaving patients desperate for medical care from clinicians. Right now, it’s easy to imagine things going wrong, especially because AI has already been accused of offering harmful advice online.
“ChatGPT and other large language models are very confident, they express themselves clearly, and they’re very often wrong,” says Mark Dredze, a professor at Johns Hopkins University. Still, he is optimistic. ChatGPT already gives advice that’s comparable to the recommendations physicians offer online, his newly published research has found. And future generative models might complement(完善) trips to the doctor, rather than replacing consultations entirely. They could help explain treatments and conditions, such as preventing misunder-standings due to language barriers. In a more promising future, AI systems would combine multiple data sources. Using photos, patient records, information from wearable sensors, and more, they could deliver good care anywhere to anyone.
As medical AI develops, the industry must keep growing amounts of patient data secure. But many hospitals have already sold sensitive patient data to tech companies. Someone suggests that the information be added to national data sets to improve medical AI models. Additionally, the government could review the accuracy of AI tools used by hospitals and medical groups and cut off valuable funding for substandard software. Doctors shouldn’t just be handed AI tools, either. They should receive extensive training on how to use them.
It’s easy to see how AI companies might trick organizations and patients into signing up for services that can’t be trusted. Lawmakers, healthcare providers and tech companies need to move ahead with caution. Lives depend on it.
1. What does the underlined word “dystopian” in Paragraph 2 probably mean （ ）
A. Uplifting. B. Practical.

B. AI will adapt and replace doctors.
C. Patients are eager for AI treatment.

3. According to Mark Dredze, what can AI possibly help do （ ）
A. Prevent illnesses.

G. The risks of early death continued to drop among those taking more steps.
Fitness tracking devices often recommend we take 10,000 steps a day. But the goal of taking 10,000 steps is not rooted in science. 1. 　 　　
The 10,000-step target became popular in Japan in the 1960s.

But today’s best science suggests we do not need to take 10,000 steps a day. 3. 　 　 In that study, people who walked about 8,000 steps a day were half as likely to die prematurely(过早地) from heart disease or any other cause as those who took 4,000 steps a day. 4. 　 The extra steps did not provide much additional protection against dying young.
5. 　 　 If, like many people, we take about 5,000 steps a day during the course of everyday activities like shopping and housework, adding the extra 2,000 to 3,000 steps would take us to a total of between 7,000 and 8,000 steps most days, which seems to be the step-count sweet spot.

人与社会 科学与技术 说明文 322 ★★
Engineers at Tufts University have developed an imaging method that can see details down to 1.6 nanometers(纳米). This new technique, developed by a team led by Professor Igor Sokolov, goes beyond traditional laboratory microscopes and even atomic force microscopy(AFM), which can only produce rough, black-and-white images that show atoms as surface dots without “color” information on the type of atom or material. By combining AFM with physical measurements and machine learning, this new method provides a high-resolution map of the material.
In this method, the atomic force microscope probe scans the surface of the sample to identify the type of molecule(分子) underneath. For example, if the material is made of different types of plastics, the technique can create a color map showing how the molecules are arranged and the tiny details of the structure. The physical measurements include the shape of the surface, the energy lost as the probe pulls away, and how much the material stretches. A total of twelve different physical measurements are recorded using AFM. The data is then processed by a computer program that creates a map for each type of material in the sample.
This imaging technology has significant potential in various fields. For example, it could speed up the development of plastic materials that degrade smoothly, layer by layer, helping to prevent microplastic pollution, which harms the environment and enters the food chain. Additionally, in healthcare, it could allow detailed studies of tooth surfaces, aiding in the development of protective coatings that better resist damage from virus.
“Nanoscale imaging can help shift plastic material development toward a more precise approach,” said Sokolov. “You mix materials and then test them under conditions that resemble real use, aging, and environmental exposure, mainly observing large and small changes in the material. By looking at these tiny changes, we can more quickly predict what might happen to these new materials over time.”
1. What is the main advantage of the new imaging method （ ）
A. Producing rough, black-and-white images.
B. Offering clear and colored images of materials.
C. Combining AFM with physical measure-ments.
D. Showing detailed information on the atom surface.
2. What is the main idea of Paragraph 2 （ ）
A. The working principle of the technology.
B. Generation of color images by AFM.
C. Data processing through machine learning.
D. The application of the technology in material analysis.
3. What does the underlined word “degrade” mean （ ）
A. Wear out. B. Break down.
C. Hold up. D. Set off.
4. In what way does nanoscale imaging help material development （ ）
A. Instant results and conclusions.
B. Testing under extreme conditions.
C. Observing small material changes.
D. Faster and more accurate predictions.

Engineers at Tufts University have developed an imaging method that can see details down to 1.6 nanometers(纳米). This new technique, developed by a team led by Professor Igor Sokolov, goes beyond traditional laboratory microscopes and even atomic force microscopy(AFM), which can only produce rough, black-and-white images that show atoms as surface dots without “color” information on the type of atom or material. By combining AFM with physical measurements and machine learning, this new method provides a high-resolution map of the material.
In this method, the atomic force microscope probe scans the surface of the sample to identify the type of molecule(分子) underneath. For example, if the material is made of different types of plastics, the technique can create a color map showing how the molecules are arranged and the tiny details of the structure. The physical measurements include the shape of the surface, the energy lost as the probe pulls away, and how much the material stretches. A total of twelve different physical measurements are recorded using AFM. The data is then processed by a computer program that creates a map for each type of material in the sample.
This imaging technology has significant potential in various fields. For example, it could speed up the development of plastic materials that degrade smoothly, layer by layer, helping to prevent microplastic pollution, which harms the environment and enters the food chain. Additionally, in healthcare, it could allow detailed studies of tooth surfaces, aiding in the development of protective coatings that better resist damage from virus.
“Nanoscale imaging can help shift plastic material development toward a more precise approach,” said Sokolov. “You mix materials and then test them under conditions that resemble real use, aging, and environmental exposure, mainly observing large and small changes in the material. By looking at these tiny changes, we can more quickly predict what might happen to these new materials over time.”
1. What is the main advantage of the new imaging method B
A. Producing rough, black-and-white images.
B. Offering clear and colored images of materials.
C. Combining AFM with physical measure-ments.
D. Showing detailed information on the atom surface.
2. What is the main idea of Paragraph 2 A
A. The working principle of the technology.
B. Generation of color images by AFM.
C. Data processing through machine learning.
D. The application of the technology in material analysis.
3. What does the underlined word “degrade” mean B
A. Wear out. B. Break down.
C. Hold up. D. Set off.
4. In what way does nanoscale imaging help material development D
A. Instant results and conclusions.
B. Testing under extreme conditions.
C. Observing small material changes.
D. Faster and more accurate predictions.

Lightning strikes about 40 million times in the U. S. every year. This natural phenomenon is terrifyingly random, and we rely mainly on lightning rods(避雷针)—a nearly 300-year-old technology—to deal with it. But researchers are exploring a more 21st-century solution: laser beams(激光束). Pioneered by Benjamin Franklin, the lightning rod works well to defend a building. But it has limited ability to protect larger land or facilities such as wind farms, airports and rocket launch pads.
Regular lightning rods are made of conductive(具有传导性的) metal. They provide a preferential point for the lightning to strike and then safely channel the charge around a building and into the ground.
In the new experiment, a high-powered laser effectively creates a towering, temporary and controllable lightning rod in the sky above the area to be protected. Scientists have dreamed of building laser lightning rods for decades, but previous experiments largely failed. Older lasers could pulse(脉冲) only around 10 times per second, too slow to keep an air column ionized(离子化), explains Aurélien Houard, a physicist at the cole Polytechnique in France and lead author of the study. The laser used in the study can fire 1,000 times per second, with each pulse lasting one trillionth of a second.
“You can burn stone if you want with this laser,” Houard says. “But it only consumes about 10 kilowatts(千瓦), roughly the power required to operate a commercial oven or seven domestic space heaters,” adds Houard.
The researchers tested their laser’s lightning-drawing ability atop S ntis, a peak in the Swiss Alps chosen because lightning often hits a telecommunication tower on the top. There, during the summer of 2021, the team observed four lightning strikes while the laser was powered on. And in all four cases, sensors—either a high-speed camera or a high-frequency electromagnetic wave detector—captured the lightning following the beam’s path. The authors hope to fine-tune the technique with more data from future studies.
“The next step will be closer to the real-world applications,” Houard says, “basically redoing this experiment, say, close to a launch pad or close to an airport.” For now, though, Benjamin Franklin’s innovation will have to do.
1. What is the major shortcoming of Benjamin Franklin’s lightning rods （ ）
A. They are too old to work.
B. They channel the charge into the ground.
C. They fail to protect larger land or facilities.
D. They are regularly made of conductive metal.
2. Why did past experiments on laser lightning rods largely fail （ ）
A. Laser beams were uncontrollable.
B. Laser lightning rods were temporary.
C. Old lasers had too slow pulse rates.
D. Old lasers failed to last long to ionize air.
3. What can be inferred from Paragraph 4 （ ）
A. The new solution is economical.
