Last year, for a nationwide teacher conference, I was asked to make a presentation about my classroom. I immediately 26 to offer to the conference photo collections and mementos （纪念物）that would prove how meaningful teachers’ work was in the world of classroom.So, for weeks, I looked 27 the drawers, boxes, and cupboard, hoping to find just the right prints that would tell of the spirit of my school and my community. All through September, I sought photos of lessons activties and accounts I had put away 28 in my house. I asked my colleagues to help me find images or objects that would 29 our most famous community members. By mid-October, I had made a list of them. But, I had also found something 30 , something muchmore dear, and very rare.I found photos of Craig, a high school senior, who gave up two weeks one summer to help little kids draw pictures at a camp. I found notes from Calvin whom I had taught for almost six years, and remembered how he always made sure every classmate felt accepted. I found a resume written by Carrie who 31 herself without the help of parents, and who took night class, and never 32 one. I found a copy of Macbeth in Portuguese, which belonged to an exchange student who read it first in her own 33 , before reading it in ours. Thus she could be sure she wasn’t missing anything important in the 34 . I found all my students, the students who had made me laugh, the students who had 35 me with their courage and kindness, the students who had 36 me to question what I knew of the world outside my own world, the students who had inspired me to expect more from them and from myself.There I was, standing at my filing cupboard reviewing 37 —not those I had taught, but the many I had learned.I came to teaching, 38 most teachers do, hoping to touch the hearts and minds of my students. What I never expected was how 39 they would touch mine.Today I walk through the door of my classroom ready to teach, but also 40 to learn from the young people who are excited to teach me about them —their insights and interests, problems and anxieties, hopes and expectations.【小题1】A. decided B. managed C. preferred D. remembered【小题2】A. at B. over C. for D. through【小题3】A. anywhere B. everywhere C. somewhere D. nowhere【小题4】A. recognize B. represent C. regard D. replace【小题5】A. unknown B. familiar C. unexpected D. funny【小题6】 A. abandoned B. enjoyed C. relaxed D. supported【小题7】A. changed B. missed C. took D. forgot【小题8】A. language B. way C. voice D. mind【小题9】 A. translation B. paper C. expression D. copy【小题10】A. trusted B. filled C. provided D. moved【小题11】A. ordered B. consulted C. recommended D. challenged【小题12】A. documents B. lessons C. essays D. classes【小题13】A. as B. since C. even if D. now that【小题14】A. carefully B. seriously C. powerfully D. slightly【小题15】A. nervous B. eager C. confident D. lucky【答案】【小题1】A【小题2】D【小题3】C【小题4】B【小题5】C【小题6】D【小题7】B【小题8】A【小题9】A【小题10】D【小题11】D【小题12】B【小题13】A【小题14】C【小题15】B【解析】试题分析：作者在参加教师会议前，想向大会提交关于自己学校和学生的照片，在同事的帮助和自己的努力下，作者找到很多资料和图片，从中作者回顾了自己的教学生涯中感人的事情，有很多感悟。

The thought of getting my hands dirty in the field never seemed interesting to me. I saw it as a boring and repetitive task. But I knew potential graduate schools would likely view my lack of field experience as a hole in my application letter. My mother also thought I should work for a few years to explore my interests before pursuing further education. So I decided to apply for field-based summer positions after graduation.After landing a job assessing the sage grouse habitat in Utah, I found myself in the company of Sherel, a 75-year-old botanist and the leader of our field crew. On the very first day of the fieldwork, I noticed a special plant on the field. “Wonderful! Looks like you’ve got a Mahonia repens,” Sherel shouted excitedly. I gently touched the plant with yellow flowers by my feet, “This one here? How can you tell it’s a Mahonia?” He paused briefly to admire the plant and then began his energetic description of the plant’s typical fe atures. That evening, while we were watching the sunset together, I texted my childhood friend. “Day I was actually kind of fun,” I started, “but we’ll see how long it takes before I get bored from just identifying plants in the field all day.”But as the weeks of fieldwork rolled by, the boredom I had expected never arrived. I came home from the field each night with sore legs and a sunburned neck, excited by the day’s finds. By picking Sherel’s brain about different species of animals and plants, I discov ered field days are about much more than identification. Each day is an opportunity to learn a little bit more. When the summer was over, I found myself in another field job, this time surveying forest in Michigan’s Upper Peninsula.I’m now a third-year Ph. D. student in ecology. Fieldwork may be buggy, wet, and physically demanding, but working with others helps keep spirits high and the physical activity helps me stay sharp. And it constantly reminds me that any task can present an opportunity to learn — as long as I am open to it.19. Why did the author join the fieldwork in Utah?A．To find out overall trends in data. B．To assess the sage grouse habitat.C．To improve his application letter. D．To realize his mother’s dream.20. On the first day of the fieldwork in Utah, the author ______.A．argued with Sherel B．complained to his friendC．became a leader of his group D．discovered a Mahonia repens21. What does the author think of fieldwork now?A．Easy but interesting. B．Boring but fruitful.C．Tiring but meaningful. D．Repetitive but demanding.22. What can we learn from the passage?A．We should explore fun in daily tasks. B．We should be open to new experiences.C．We should respect the people around us. D．We should be determined about ourgoals.An AI model can be used to detect stress in office workers based on how they use their mouse and keyboard. A new study suggests that a machine-learning model using these two elements was more accurate at detecting stress in people than a model that tracked their heart-rate data.“We saw that the models that just used the mouse and keyboard data performed better than the models that had the heart-rate data in it,” says Mart Naegelin. a Ph. D. student at the Swiss Federal Institute of Technology, and one of the stu dy’s authors.Naegelin and her fellow researchers used machine-learning models to analyze data on keyboard-typing activity, mouse movements and heart-rate data. They also studied the data of a combination of two or all three of these elements to determine which performed best in terms of measuring stress. They found that the model trained on mouse and keyboard data performed better than the model that used mouse, keyboard and heart rates. Of the single-modality (形态) models, the heart-rate data performed the worst. “The test was conducted in an environment that simulated an office environment, so the results still need to be confirmed in real-life scenarios (情况),” Naegelin says.In the experiment, participants were divided into three groups. A control group carried out assigned tasks, such as planning meetings and collecting data, with no additional work. A second group at times answered questions from managers in person in a mock interview scenario while completing other assigned tasks. And members of a third group were, at certain points, interrupted with additional questions sent through an online chat on top of tasks assigned to other groups. At regular intervals during the experiment, participants were asked to rate their stress levels through a computer questionnaire.Researchers learned that workers made longer, less accurate movements with their mouse, as well as more typing errors, when they were stressed. Shorter, more direct movements with the mouse were tied to lower stress levels. The study didn’t f ocus on why increased levels of stress are thought to affect muscle activity.The researchers say they believe a stress-detection system that logs keyboard and mouse movements might be beneficial as a self-help tool for employees alongside other initiatives to improve workplace mental health. But employee participation would need to be optional and based on informed consent (同意), and companies would need to commit to protecting user privacy.It remains to be seen how this technology will evolve and be adopted in practice, but the potential for AI to contribute positively to employee well-being is an appealing avenue for future exploration.23.

A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past massextinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.27. The first two paragraphs are written to _______.A．describe an event B．raise a questionC．present an opinion D．make a comparison28.
