At first, the result seemed _____ [1] _____: the system found a blue bottle even when the owner's photo showed only half of it. Problems appeared during a real test. The program often confused identical black umbrellas. It also gave a high match score to any red bag, although shape and size were _____ [2] _____. More seriously, a test photo included a student's face in the background. The team had built an object finder, but they had also created a system that could collect _____ [3] _____ information. The students changed both the technology and the rules. Faces and name tags were automatically covered before a photo was _____ [4] _____. Images stayed on the school computer instead of being sent to an outside service. A match was shown as a _____ [5] _____, not a final decision. Staff still checked where and when the object had been found. To improve _____ [6] _____, the team added side views and size markers. Yet they refused to train the program on secretly collected photos. Fewer images meant slower improvement, but consent was treated as part of the design rather than a delay. The revised system recovered 63 percent of test objects. That number was lower than the first exciting claim, which had counted several wrong matches. The team presented both the _____ [7] _____ and the failures at the science fair. Their project did not win the "Most Powerful Technology" prize. It received an award for responsible problem-solving. The students learned that a better tool is not simply one that can do more.

Some trees stood in shade and needed little water; others grew beside hot stone walls and dried quickly. A student research team created a map that combined three kinds of information. Small temperature sensors measured how hot the soil surface became. Moisture readings were taken by hand twice a week. A camera on a kite photographed leaf color from above; no faces or private gardens were included. The map did not tell workers simply to "water" or "do not water." It marked places that needed checking first. During the first month, the team made a serious mistake. Dark red leaves were read as signs of dryness, but one tree species naturally produced red new leaves. The students added species information and asked gardeners to review alerts. False warnings fell, though they did not disappear. Compared with the previous summer, the park used 18 percent less water on young trees, and a similar number survived. The result cannot be credited to the map alone because the summer was slightly cooler. Still, gardeners said the priority list helped them spend more time on trees whose condition was uncertain. The tool's greatest value may be that it directs human attention instead of pretending to replace it. 1. What problem did the project address? A. Workers refused to water young trees. B. The park had no information about tree species. C. All trees received water according to the same schedule despite different needs. D. Kites could not fly above the park. 2. What did the map actually provide? A. A list of places that should be checked first. B. A final automatic watering decision. C. Photos of private gardens. D. The exact age of every tree. 3. Why were red leaves a problem for the first model? A. The camera could not see red. B. All dry leaves were green. C. Gardeners had painted the leaves. D. Some healthy new leaves were naturally red. 4. Why can't the 18 percent reduction be credited only to the map? A. No trees survived. B. The summer weather was also different. C. The sensors used more water. D. The team stopped measuring moisture. 5. What does the final sentence suggest about good technology? A. It should remove people from every decision. B. It is valuable only when it is perfectly accurate. C. It can help people focus their judgment where it is needed. D. It should collect as much private data as possible. B Forty-Eight Hours, One Useful Button At a weekend coding event, a team of teenagers planned an app that would identify every difficulty in a student's homework and create a complete study plan. Six hours later, they had a beautiful screen and almost nothing that worked. Mentor Jia Wen asked them to choose one moment that students found frustrating. The team interviewed participants and heard the same complaint: when checking a long online exercise, users had to open each wrong answer separately before they could see the type of mistake. The team abandoned its grand plan. It built one button that grouped wrong answers into teacher-defined labels such as "word form," "evidence" and "calculation step." The program did not decide why an answer was wrong; teachers created the label when they wrote the question. The button simply turned existing information into a review list. By Sunday afternoon, the tool worked. It was not an AI tutor and it did not produce personal advice. Yet testers spent less time finding mistakes and more time correcting them. The team won no prize for technical difficulty. It did win the users' choice award. Team member Su Yi later said the hardest part was giving up an impressive idea. "We thought ambition meant adding functions," she explained. "Now I think it can mean protecting the one function that solves the real problem. 1. Why did the team's first plan fail to progress? A. They had no screens. B. Students had no homework difficulties. C. The mentor asked them to stop coding. D. The idea was too broad to build usefully in the available time. 2. What repeated problem did interviews reveal? A. Students could not submit answers. B. Users spent too much time opening mistakes one by one. C. Teachers used no labels. D. Online exercises were too short. 3. Who decided the type of each mistake? A. The program itself. B. A camera. C. The teacher who created the question. D. Other students after the event. 4. Why did users value the final tool? A. It made the correction process more efficient. B. It gave perfect personal advice. C. It contained the most functions. D. It replaced their teachers. 5. What did Su Yi learn about ambition? A. Ambition always requires more technology. B. Winning a technical prize is the only goal. C. Interviewing users limits creativity. D. A focused solution can be more valuable than many impressive features. C Should the Study Assistant Show Its Confidence? A school tested two versions of a study assistant that answered questions from the school's science notes. Version X displayed one answer in a confident tone. If no answer was found in the notes, it still produced a likely response. Version Y showed the paragraph used for its answer and one of three labels: strong support, partial support or not found. After 200 test questions, Version X answered 176 and Version Y answered 158. However, 31 of Version X's answers were unsupported or wrong, compared with 8 from Version Y. Students using Version Y checked the source paragraph 64 percent of the time when the label said partial support. Students using Version X opened the notes only 18 percent of the time. In interviews, some students preferred X because it felt faster and smoother. Others said Y helped them decide when to ask a teacher. The school chose Y for a longer trial, but it also shortened the labels and added a button for reporting an unclear source. The goal was not to make the assistant sound uncertain all the time. It was to make the level of evidence visible. 1. What did Version Y show that Version X did not? A. Only a faster answer. B. A source paragraph and a support label. C. A student's private grades. D. Answers from the whole internet. 2. Which version answered more questions? A. Version Y. B. They answered the same number. C. The passage does not say. D. Version X. 3. What was a major weakness of Version X? A. It gave more unsupported or wrong answers in a confident style. B. It refused every unsupported question. C. Students checked the notes too often. D. It never produced likely responses. 4. Why might the school prefer Version Y despite fewer answers? A. It removed all need for teachers. B. It guaranteed every answer was correct. C. It made evidence and uncertainty easier to judge. D. It sounded more confident. 5. What was the purpose of adding a reporting button? A. To hide the source paragraph. B. To let users improve the system by identifying unclear evidence. C. To make labels longer. D. To increase unsupported answers.

It is a chain in which each development answers a need or creates a new choice. _____ [1] _____ Begin with the original situation. Who experienced the problem, and why did the old method fail? _____ [2] _____ "Communication was difficult" is weaker than "mountain doctors waited hours for road-delivered test results." Next, select turning points rather than every date. A turning point changes what becomes possible: a smaller battery extends flight time, a new rule protects users, or a failed test changes the design. _____ [3] _____ Then connect the technology with a human result. Faster is not automatically better. _____ [4] _____ Ask who gains time, safety or access, and what new risk must be managed. End with the present choice, not empty praise. _____ [5] _____ A good retelling helps readers understand both the path already taken and the decision that comes next. A. Exact details make the need visible. B. The newest device should always be called a miracle. C. The structure is often need - attempt - turning point - result - next question. D. Explain why each selected moment matters to the later story. E. Technology continues to develop, so its story remains open. F. Its value depends on what the extra speed allows people to do. 1. ________________ 2. ________________ 3. ________________ 4. ________________ 5. ________________ VII. 短文填空（共10小题；每小题1.5分，满分15分） 阅读下面短文，根据语境或括号内提示填入一个适当的词或所给词的正确形式。 A Crosswalk That Waits The crosswalk outside Zhonghe Hospital has a button _____ [1] _____ allows people to request extra crossing time.
