（2025·江西·模拟预测）In recent years, China’s progress in artificial intelligence (AI) has drawn global attention.Meanwhile, a quieter yet equally significant transformation has been taking place in biotechnology.Traditionally known for producing common medicines and supplying raw materials, China has now emerged as a leader in innovative drug development. It is now the world’s second-largest source of new medicines, behind only the United States.

Some Western pharmaceutical companies (制药公司), which face potential losses of $140 billion annually because their drug patents are running out, are increasingly looking east for ideas. In 2023, nearly a third of major licensing deals were with Chinese firms, a threefold (三倍的) increase from 2020. According to LEK company, the total value of drugs licensed globally from China grew 15 - fold to $ 48 billion. Major pharmaceutical firms like Merck have secured licensing deals with Chinese biotech companies, such as LaNova Medicines, further demonstrating the industry’s growing appeal.

China’s biotech boom began seriously after official reforms in 2015. These changes reduced approval times for early-stage human testing from 501 to 87 days, and brought China in line with international standards. At the same time, the country benefited from returning scientists who had studied or worked abroad. A massive domestic market and relaxed listing regulations also fueled private investment, which rose sharply from $1 billion in 2016 to $13.4 billion in 2021.

Rather than simply producing generic drugs, Chinese firms have adopted a “fast-follower” approach, changing existing drugs to enhance safety, effectiveness, or delivery. This strategy has allowed for quicker and more cost-effective drug trials.

One area where Chinese companies have excelled (优于) is antibody-drug conjugates (ADCs), a promising cancer treatment. Since ADCs rely on existing components, success depends on optimizing their combination, an area where China has been very successful. Faster clinical trials provide another advantage. With a large patient population and government support, Chinese trials are often two to three times faster than those in the West. This efficiency has drawn interest from global pharmaceutical firms.

193．Why is China’s progress in AI mentioned?

A．To discuss AI’s global impact. B．To highlight China’s biotech rise.

C．To cite a major biotech breakthrough. D．To compare AI and biotech development.

194．What mainly drives Western companies to cooperate with China?

（2025届辽宁省丹东市高三下学期总复习质量测试（二）英语试题）Isabel Crook, a Canadian educator and anthropologist (人类学家), spent over 90 years in China, making significant contributions to both English education and cultural understanding. Born in Chengdu in 1915 to Canadian churchman parents, Crook returned to China after completing her master’s degree in anthropology at the University of Toronto. Her life was deeply connected with China’s history and development.

Crook is best known for her pioneering work in English language education in China. In 1948, she accepted an invitation from the Chinese Communist Party to teach at the Central Foreign Affairs School, which later became Beijing Foreign Studies University. She spent over six decades there, contributing to forming China’s first university English curriculum and training generations of English teachers. Her efforts helped lay the foundation for modern English education in China, earning her the title of “Lifetime Honorary Professor” from the university.

Beyond education, Crook was also a devoted anthropologist. She conducted extensive field research in rural China, including in Xinglongchang in Sichuan and Shilidian in Hebei. Her books, such as Revolution in a Chinese Village, Ten Mile Inn and Xinglongchang, Field Notes of a Village Called Prosperity, offer detailed and intimate portraits of Chinese rural life during the revolutionary period. These works have provided valuable insights into China’s social transformation and have been influential in shaping Western understanding of China.

Crook’s commitment to China extended beyond her professional life. She and her husband, David Crook, supported various social projects, including setting up clinics, schools, and scholarships for poor students. Even after retiring at the age of 66, she continued to contribute by returning to rural areas to support education and development initiatives.

In recognition of her contributions, Isabel Crook received numerous honors, including the “Friendship Medal” from the Chinese government in 2019.

（海南省2024-2025学年高三下学期学业水平诊断（五）英语试题（含听力））Tiny bits of plastic, called micro plastics, pollute the air and our food. Plastic bits have been found everywhere from our bodies to a dolphin’s breath. That’s why scientists keep looking for ways to handle them. Now, they’ve discovered a new strategy.

Bacteria (细菌) common in wastewater can break down a type of plastic — PET. That finding could inform new ways to clean up PET pollution. Scientists have long known Comamonas, a kind of microbe (微生物), grow on plastics in water. That got Ludmilla Aristilde,a biochemist, wondering if the microbes use PET as food.

PET is the world’s most widely used plastic. Some 56 million tons of it is made each year — mostly for polyester clothing, water and soda bottles, and the packaging of many store-bought goods. That leads to a lot of PET pollution. Tiny pieces of PET come out of polyester clothes when they’re washed — and flow through water treatment plants into waterways. Bits of PET also get into waterways as plastic bottles and other PET packaging break down in the environment.

In past work, Aristilde discovered that one strain of Comamonas could break down rings of carbon atoms in laundry detergent (洗涤剂). Those carbon rings, she notes, were similar to the ones found in plastics. Here was a clue that the microbes may be able to break down PET as well.

Aristilde’s team grew Comamonas in the lab recently. Then they placed the microbes in a liquid-filled container for a month with tiny bits of PET. Afterward, they looked at the surface of the plastic with a special scanning microscope, which can create very detailed images of surfaces. The team found nanoparticles (纳米颗粒) of PET now floated in the water. At the end of the month, more than three times as many nano bits were in the water as before. This showed that the bacteria had been decompounding the PET. The bacteria also multiplied faster when they had PET available. That suggests they were using carbon molecules from the plastic bits as food.

Ren Wei, a biochemist, says the tiny organisms eat super tiny amounts of plastic. He adds that the rate at which they consume PET is far too slow to remove much of the vast amounts that enter the environment each year.

185．Why is a dolphin’s breath mentioned in paragraph 1?

A．To show plastic pollution is a widespread problem.

B．To display the harmful effect of micro plastics on sea creatures.

C．To prove micro plastics can exist in wastewater for a long time.

D．To illustrate the strong ability of dolphins to detect micro plastics.

186．What does paragraph 3 mainly talk about?

A．Wide uses of PET in life. B．Basic functions of PET.

C．Various sources of PET pollution. D．Main characteristics of PET pollution.

187．What does the underlined word “decompounding” in paragraph 5 probably mean?

A．Taking over. B．Searching for. C．Sheltering from. D．Breaking apart.

188．What’s Ren Wei’s attitude to using the microbe to clean up PET pollution?

A．Unclear. B．Doubtful. C．Positive. D．Unconcerned.

（2025届河北省高考三下学期高考冲刺模拟考试（Ⅱ）英语试题）Scientists in Australia have used Artificial Intelligence (AI) to help them locate a rare bird called the Plains-wanderer. This new information will help scientists protect the birds, which are endangered.

The Plains-wanderer is a small bird that lives in Australia’s grasslands. Not just any grasslands. Plains-wanderers are picky. There can’t be too much grass or too little. Zoos Victoria, the group behind the recent effort to locate Plains-wanderers, says the birds’ number has fallen by over 85% in recent decades as grasslands have been turned into farms and cities. Scientists believe there are now only 250 to 1,000 of the birds left in the wild. Scientists have put the species into a “family” all by itself, since there are no other similar birds. The female Plains-wanderers are larger, and are in charge of protecting the territory while the male birds are smaller and take care of the eggs.

To protect these rare birds, scientists first had to learn where they were, so Zoos Victoria worked with Queensland University of Technology on a plan to locate the birds. Since Plains-wanderers were hard to spot, the team chose to “listen” for the birds instead. Female Plains-wanderers make an unusual “Ooom” call, and this is the key to locate them.

The researchers set up 35 special recording devices called “song meters” in nine different grassy areas where Plains-wanderers could possibly have been. Song meters recorded all the sounds made in an area over a long period of time. The song meters collected tens of thousands of hours of recordings——far more than humans could analyze. So the researchers fed the recordings to an AI system trained to identify the calls of Plains-wanderers. The AI system discovered Plains-wanderer calls coming from two of the sites. The scientists double-checked and found that the AI system was correct. Chris Hartnett, who worked with Zoos Victoria, said it was like “finding gold”.

The new information will help scientists protect the birds. And the researchers are still “listening”— using song meters and AI to try to locate more of these Goldilocks birds.

181．What is the primary cause for the Plains-wanderers’ population decline?

A．Habitat loss. B．Climate change. C．Increased enemies. D．Lack of food sources.

182．What can we know about Plains-wanderers from paragraph 2?

A．Their physical characteristics are unique. B．They are the only birds that live in grasslands.

C．They belong to a family with no close relatives. D．The female are more responsible than the male.

183．What does the underlined sentence imply in paragraph 4?

A．The discovery is valuable. B．The birds prefer the grassland.

C．The birds are as expensive as gold. D．The protection of the birds is vital.

184．Why is AI essential in this research?

A．It predicts the future population trends. B．It replaces the need for human scientists.

C．It processes amounts of sound data efficiently. D．It makes bird calls to attract Plains-wanderers.

（2025届河北省高考三下学期高考冲刺模拟考试（Ⅱ）英语试题）Much has been written about how modern lifestyles mean we are no longer getting enough sleep, unlike our ancestors living in less technologically advanced times. However, an analysis of 54 sleep studies has found that people in small, non-industrialized societies actually get less sleep than those in more industrialized regions.

It is often assumed that the rise of electronic devices like smartphones means that people today are sleeping less than in the recent past. Many studies that report a decrease in sleep in the past few decades are based on asking people how long they sleep, which is an unreliable measure. Research using more reliable assessment tools, such as physical activity monitors, hasn’t found a decrease over recent decades. But these studies are done in industrialized countries, leaving open the question of whether people got more sleep prior to industrialization.

The availability of wearable sleep monitors has made it easier to study sleep in non-industrialized societies. McKinnon and her colleague David Samson have now analyzed 54 sleep studies, comparing sleeping habits in industrialized societies, including the US, Australia and Sri Lanka, with those in smaller, non-industrialized communities, including Indigenous peoples in the Amazon, Madagascar and Tanna Island in the Pacific.

The 54 studies involved direct measurements of sleep in people aged 18 and over who had no serious health conditions. The pair found that in non-industrialized societies, the average was 6.4 hours, compared with 7.1 hours in industrial societies. They also found that people in non-industrialized societies were asleep for 74 percent of the time they were in bed, compared with 88 percent in industrial societies, a measure known as sleep efficiency.

Samson owes the higher sleep duration and efficiency in industrialized societies to safer and more secure sleep conditions. He remarks, “We no longer need to worry about enemies or predators (捕食者) at night.” “While these studies involve only 866 people in total, the data set is the most comprehensive yet,” says Samson.

177．What is the misconception about sleep?

A．People with less advanced technologies sleep less.

B．People in non-industrialized societies get less sleep.

C．The increasing use of phones impacts sleep positively.

D．Modern lifestyles lead to a decrease in people’s sleep time.

178．How did McKinnon and Samson conduct their research?

A．By analyzing previous studies on sleep. B．By comparing the data set of sleep habits.

C．By recording people’s sleep time directly. D．By measuring sleep duration and efficiency.

179．What can be learned from McKinnon and Samon’s analysis?

A．Americans have lower sleep efficiency.

B．Sri Lankans sleep 6.4 hours per day on average.

C．Amazons enjoy safe and secure sleep conditions.

D．Tanna Islanders have less sleep than Australians.

180．What is Samson’s attitude towards the 54 studies?

A．Doubtful. B．Cautious. C．Dismissive. D．Approving.

（24-25高一下·黑龙江黑河·期中）The Free Colorado-Based Educational Program

Brief introduction

Participants in Girls on Rock get to explore forests, hike mountains and sleep under the stars. But that is only part of the experiences young women seek in the free Colorado-based educational program. The program also provides them with the chance to carry out field research with actual scientists.

The group supports similar programs in the American states of Alaska and Washington, and in the countries of Canada and Switzerland.

Evelyn Cheng, an ecologist, and Megan Blanchard, a chemical ecologist, began developing the program in 2014. They were both studying at the University of Colorado Boulder from 2002 to 2006.

（24-25高一下·安徽·期中）In Switzerland, one in three employees suffers from workplace stress. Those affected often don’t realize that their physical and mental resources are weakening until it’s too late. This makes it all the more important to identify work-related stress as early as possible where it happens: in the workplace.

Researchers at ETH Zurich are now taking an extremely important step in this direction. Using new data and machine learning, they have developed a model that can tell how stressed we are just from the way we type and use our mouse.

To develop their stress model, the ETH researchers observed 90 study participants (参与者) in the lab performing office tasks that were as close to reality as possible, such as scheduling meetings or recording and studying data. They recorded the participants’ mouse and keyboard behavior as well as their heart rates. In addition, the researchers asked the participants several times during the experiment how stressed they felt.

While some participants were allowed to work quietly, others also had to take part in a job interview. Half of this group were also repeatedly stopped by chat messages. In contrast to earlier studies by other scientists, where the control group often did not have to solve any tasks at all and could relax, in the ETH researchers’ experiment, all participants had to perform the office tasks.

The ETH researchers proved that stressed people type and move their mouse differently from relaxed people. “People who are stressed move the mouse pointer more often and less exactly and cover longer distances on the screen. Relaxed people, on the other hand, take shorter, more direct routes to reach their destination,” says Nägelin, a mathematician who conducts research. What’s more, people who feel stressed in the office make more mistakes when typing. They write on and off with many short pauses (停顿). Relaxed people take fewer but longer pauses when typing on a keyboard.

170．Why do researchers at ETH Zurich develop the stress model?

A．To find suitable solutions to pressure. B．To ensure employees’ physical health.

C．To identify employees’ job-related pressure. D．To examine employees’ stress-related illnesses.

171．What can be known from the process of building the model?

A．The participants were asked various questions.

B．The participants performed the same office tasks.

C．The control group did nothing but relax themselves.

D．Some participants were repeatedly stopped by messages.

172．What will happen if a man at work is under much stress?

A．He may feel relaxed when typing. B．He may move the mouse pointer exactly.

C．He may make more mistakes when typing. D．He may type a document without any stop.

173．What is the most suitable title for the text?

A．Several ways to reduce our pressure at work.

B．Checking your pressure level through a stress model.

C．The great influence of much pressure on our work.

D．Detecting stress in the office from how people type and click.

（24-25高三下·重庆·阶段练习）A while back, I met a capybara (水豚) named Pisuke in Tokyo. I sat on a couch next to him, stroking his straw-like fur and the pinkish skin beneath, thick as sailcloth. His ears looked like mushrooms, twitching occasionally. I scratched under his chin, and he half-closed his eyes. “How is this animal even real?” a friend asked after I showed her a selfie. My connection to them predates the internet craze.

The capybara’s unreality is partly why it has such a strong fan community. The past years have seen the rise of capybara on TikTok and Instagram. If you’ve followed them on social media, you might know they get hiccups, carry large oranges on their heads, and allow birds to clean their fur. After my half hour with Pisuke, I felt immersed in a deep well-being. Time flowed differently, and my vision softened. The world felt pure and unaggressive. We were all living our lives as the giant creature that never meant anybody any harm.

In a world of conflict, instability, and fast-paced culture, people seek comfort and peace. It’s led them to the meditative, wholesome faces of the capybara.

“One misconception is that they’re so cool,” Somma said. The capybara is a predator (捕食者) in its native habitat, with predator reactions, especially when cornered for humans hunt them for meat and skin. To avoid scaring it, I squatted and moved toward it slowly. Its flightiness reminded me of childhood bullying, my constant need to find an exit when surrounded by overly enthusiastic people. I realized the capybara represent a dilemma I knew too well: a friendly creature always afraid of attack. Do we love them because we, too, feel trapped in a world that encourages hyper-socializing yet rewards us with existential anxiety?

I asked Somma why people like me are drawn to capybaras. “They’re sweet animals,” she said. “You can connect with them without physical contact.” I was astonished by how well the writers and directors portrayed the capybara in the film: mostly sleeping, eating grass, and getting along with other animals. When scared, it withdrew. An unlikely hero, but a perfect one for our times.

163．What is a key reason for the capybara’s popularity?

A．Their gentle nature. B．Their lively behavior.

C．Their high intelligence. D．Their endangered status.

164．How did the author feel after interacting with Pisuke?

A．Bored but peaceful. B．Immersed and calm.

C．Restless and unaggressive. D．Energetic and hyper-social.

165．What does Somma emphasize about capybaras?

A．They are always cool. B．They are top predators in their habitat.

C．They reproduce better in a stable world. D．They preserve natural tendency of predators.

166．Why does the author consider the capybara “a perfect hero for our times”?

A．They defend themselves when threatened.

B．They avoid physical contact to protect their emotions.

C．Their quiet, withdrawn existence mirrors modern anxieties.

D．They have hyper-social confidence while physically weak.

（24-25高三下·重庆·阶段练习）Stories written by the latest version of ChatGPT were nearly as good as those written by human authors, according to new research on the narrative skills of artificial intelligence. But when people were told a story was written by AI — whether the true author was an AI or a person — they rated the story poorly, a sign that people distrust and dislike AI-generated art.

“AI is good at writing something that is consistent, logical and coherent. But it is still weaker at writing engaging stories than people are,” said Haoran “Chris” Chu, Ph.D．, co-author of the new study. Chu and his co-author, Sixiao Liu, Ph.D．, published their findings in the Journal of Communication.

The researchers exposed people to two different versions of the same stories. One was written by a person and the other by ChatGPT. Survey participants then rated how engaged they were with the stories. To test how people’s beliefs about AI influenced their ratings, Chu and Liu changed how the stories were labeled. Sometimes the AI story was correctly labeled as written by a computer. Other times people were told it was written by a human. The human-authored stories also had their labels bartered.

The surveys focused on two key elements of narratives: counterarguing — the experience of picking a story apart — and transportation. “Transportation is a very familiar experience,” Chu said. “It’s the feeling of being so engaged in the narrative you don’t feel the sticky seats in the movie theater anymore. Because people are so engaged, they often lower their defenses to the persuasive content in the narrative and reduce their counterarguing.”

While people generally rated AI stories as equally persuasive as those written by humans, the computer-written stories were less effective at transporting people into the world of the narrative.

“AI does not write like a master writer. That’s probably good news for people like Hollywood screenwriters — for now,” Chu said.

159．What does the author highlight about AI-generated stories in paragraph 1?

A．They are lacking in coherence. B．They are discriminated against.

C．They show great narrative skills. D．They rely partly on human work.

160．What does the word “bartered” underlined in paragraph 3 mean?

A．Rated. B．Attached.

C．Removed. D．Exchanged.

161．What can we infer about counterarguing and transportation?

A．They work in conflict with one another.

B．They are both need improving for authors.

C．They increase the persuasive power of a movie.

D．They apply to understanding different narratives.

162．What is Chu’s view on AI writing for Hollywood movies?

A．It is unrealistic at present.

B．It will be a win-win story.

C．It is a well-established fact.

D．It will prove fruitless anyway.
