The rise of AI doctors is not like something from science fiction anymore. It’s really happening now. In different parts of China, AI doctors are bringing big changes to the medical field.
Last year, Beijing Children’s Hospital brought in the country’s first AI pediatrician (儿科医生). An 8-year-old boy had a sudden and serious illness. Thirteen top experts were trying hard to find the best treatment. At the same time, the AI doctor came up with a treatment plan and it was like the human doctors’ thoughts.
In Shandong, a couple was very distressed when their child had a high fever. They decided to try DeepSeek before going to the hospital. After putting in the description of the illness, the AI said it was probably a bacterial infection (细菌感染 ) and suggested some medicine. When they went to the hospital, the doctor gave exactly the same medicine.
Even in some villages of Jiangsu, AI doctors help patients know about their illnesses and make it easier for disabled people to move around in the hospital.
All these examples show us two important things AI doctors can do. They can help top doctors make better choices and they can also make healthcare easier for everyone in the country. However, AI doctors need to make more improvements. As one doctor said, “AI doctors can give us ideas, but we still need the care given by humans.”
26．How does the writer describe the AI doctor’s role in Paragraph 2
A．By listing many numbers. B．By telling a real story.
C．By asking some questions. D．By teaching a lesson.
27．What does the underlined word “distressed” in Paragraph 3 mean
A．Bored. B．Relaxed. C．Excited. D．Worried.
28．What can we learn about AI doctors from the passage
A．AI doctors cannot offer help in the villages.
B．AI doctors can help disabled people move around in the hospital.
C．AI doctors are able to do everything for the patients.
D．AI doctors don’t need improvements any more.

A kind of grass from China has been making a difference. It can be cut into pieces and used as a substrate (培养基) for growing mushrooms (蘑菇) ; it is a kind of feed for farm animals; it also blocks strong desert winds. This plant is called Juncao or “mush-room grass”.
The Juncao technology has achieved success. The technology has been introduced into over 100 countries. Local farmers’ incomes (收入) have increased a lot, after they grew mushrooms with Juncao. The technology won the Prize of the State of Geneva at the 20th International Exhibition of Inventions.
Scientist Li Zhanxi was the inventor of the Juncao technology. In an interview, Li shared his experience of inventing the Juncao technology. “In the 1970s, China introduced a mushroom growing technology that used wood as substrates to help farmers in mountainous areas. But the method led to deforestation (毁林) . More forests were cut down to provide wood. To solve the problem, we needed to find other ways. We had many difficulties during the research process. The most difficult part was that we didn’t have past experience to learn from. We tested many kinds of grass to see which one could be used to grow mush-rooms. After three years of hard work, we succeeded in growing mushrooms with grass instead of trees. This is the Juncao technology.”
All of us are proud of this invention “Juncao” or “mushroom grass”.

Traffic laws are the rules of the road that keep drivers, people on bikes and people on foot safe. Among all traffic control devices, the traffic light is the most important. But have you ever wondered why red means “stop” and green means “go”
The history of traffic lights started with railway systems in the 19th century. Red was chosen as “stop” because it could be seen from a much longer distance than other colours, even in fog or rain. At first, green meant “be careful” and white meant “go”. But there was a serious problem. Sometimes the red cover of the light would fall off or break, showing the white light behind it. A train driver might see the white light and think it was safe to go, causing terrible accidents.
To solve this problem, people changed the colours. Green was used to mean “go” because it was very different from red and easy to see. Later, yellow was added to mean “be careful” or “slow down” because it was bright and caught people’s attention easily. Today, these colours are used in the same way all over the world. They give clear instructions and stop the roads from being in a mess.
37．Where did traffic lights first start
A．Railway systems. B．Bus systems. C．Plane systems. D．Bike systems.
38．Why was red chosen to mean “stop” in the early traffic lights
A．Because it was a bright color.
B．Because it could be seen from far away.
C．Because it was the first colour used.
D．Because it looked like a warning sign.
39．What is Paragraph 3 mainly about
A．The bright colour of yellow. B．The meaning of traffic lights.
C．The development of the colours. D．The importance of being careful.
40．In which part of a magazine can we most probably read this passage
A．Modern Art. B．Health Care. C．Science History. D．Sports News.
四、任务型阅读
Have you watched the “space food live stream” (太空吃播) Chinese astronauts on Tiangong Space Station recently shared their special “barbecue” moment, which was a big surprise. The star tool behind this is a new hot-air oven.
In the video, astronauts first took out chicken wings and fixed them on special racks. After 28 minutes’ heating, the wings turned golden. Then they baked (烘烤) black pepper steak together, and the delicious smell made them excited.
Baking in space is a big challenge. The smoke and oil fumes could have an effect on the station’s air quality. This space oven is not like the ones on Earth. It uses technologies like oil collection and multi-layer filtration (多层过滤), meeting the strict air quality standards of the space station. It can work for more than 500 times for long-term tasks.
The oven is part of China’s hard work to make astronauts’ life better. Now there are over 190 kinds of food on the station. The menu changes every 10 days. The “space garden” grows fresh vegetables, adding more nutrition (营养) to their meals.
Experts say self-baked food brings not only taste enjoyment but also spiritual comfort (心灵的慰藉) to astronauts living in a narrow space for months. This oven shows China’s progress in space technology and its care for astronauts’ daily life. It’s really a warm gift from Earth to the universe.
根据语篇内容，按要求回答问题。
41．What is the star tool during the “space food live stream”
42．How long did it take to bake the chicken wings in the space station
43．What is the big challenge when baking in space

【导语】本文讲述了电脑在日常生活中的应用以及不同人对电脑的看法。
1．句意：电脑在日常生活中是有帮助的。
根据后文“they can help people save much time...”可知，此处强调电脑的积极作用。helpful“有帮助的”符合语境。cheap“便宜的”、similar“相似的”、beautiful“美丽的”均无法概括后文提到的功能优势。
2．句意：当人们无法完成工作时，它们能帮助人们轻松地解决问题。
前文提到电脑能做很多工作来节省时间，因此在人做不了时，电脑能让人更“轻松”地解决问题。easily“容易地、轻松地”符合逻辑。clearly“清楚地”、early“早地”、excitedly“兴奋地”与解决难题的语境搭配不当。
3．句意：在二十一世纪，大多数人都会使用电脑。
整篇文章的主题就是关于“computers”，且下文提到“More and more families have their own computers”，故此处填 computers“电脑”。knives“刀”、dictionaries“字典”、maps“地图”均偏离主题。
4．句意：父母为他们的孩子购买电脑。
根据常识及下文孩子使用电脑的情景，父母通常是给孩子买电脑。make“制作”、check“检查”、clean“打扫”不符合家庭获取电脑的方式。
5．句意：但是有许多老师和父母说电脑不能帮助孩子进步，反而使他们学习落后。
空格后提到“make them fall behind in study”，最关心学生学业进度并对此发表看法的通常是 老师。actors“演员”、scientists“科学家”、workers“工人”不如老师贴切。
6．句意：所以有些父母不让他们的孩子使用电脑。
由于担心孩子学习落后，父母会禁止或不让孩子用电脑，hear“听到”、notice“注意”、see“看见”均无“允许/禁止”之意。
7．句意：在一些国家，甚至一些科学家也不喜欢电脑。
下文解释说电脑导致人们失业，因此科学家对电脑持负面态度，即don’t love。sell“卖”、forget“忘记”、move“移动”不符合语境中表达的情感倾向。
8．句意：他们说电脑让很多人失去了工作，因为电脑比人工作时间更长。
电脑替代人力导致的直接后果是失业，即lose their jobs“失去工作”。answers“答案”、gifts“礼物”、hobbies“爱好”均不符合因被替代而失去的东西。
9．句意：我不同意这个观点。
前文问“Are computers bad ”，随后作者提出如果使用得当电脑是有益的，说明作者反对“电脑是坏的”这一看法。don’t agree with表示“不同意”。write down“写下”、think about“思考”、look for“寻找”语义不通。
10．句意：如果人们以正确的方式使用电脑，电脑对他们是有好处的。
对应前文的争议，作者强调关键在于使用方法，只有用正确的方式，电脑才能发挥好的作用。simple“简单的”、free“免费的”、boring“无聊的”均不能体现“合理使用”这一核心逻辑。
11．Chinese 12．made 13．Actually 14．First 15．like 16．artists 17．pictures 18．to make 19．into 20．smoothly 21．carefully 22．for 23．their 24．engineers 25．the

【详解】11．句意：3D动画受到各地人们的喜爱，并且中国的动画现在制作得非常精湛。根据名词“animations”可知，此处需填形容词作定语，表示“中国的”。China的形容词是Chinese。
12．句意：但是一部3D动画是如何制作出来的呢？主语“a 3D animation”与动词make之间为被动关系，且为特殊疑问句，应用被动语态。make的过去分词是made。
13．句意：实际上，这是一段迷人的旅程。此处位于句首修饰整个句子，应用副词形式。actual的副词是actually，句首首字母大写。
14．句意：首先，团队确定基本创意。此处表示顺序“首先”，应用副词first，句首首字母大写。
15．句意：他们通常选择像《哪吒》这样的经典中国故事，或者采用原始故事来传递积极的价值观。此处表示举例“像……一样”，应用介词like。
16．句意：然后，艺术家们设计生动的角色。此处需填名词作主语，表示“艺术家们”，且谓语动词design为原形，主语应为复数artists。
17．句意：接下来绘制详细的画面，并且添加鲜艳的色彩使角色栩栩如生。此处需填名词作主语，表示“画面”，且谓语动词are drawn为复数，主语应为复数。picture的复数是pictures。
18．句意：接下来绘制详细的画面，并且添加鲜艳的色彩使角色栩栩如生。添加色彩的目的是为了“使角色栩栩如生”，应用动词不定式to make作目的状语。
19．句意：这些画面随后通过专业软件被转换成3D模型。固定搭配turn into“变成”，此处应用介词into。
20．句意：它们被一帧一帧地平滑地组合在一起。此处需修饰动词“are put together”，应用副词形式。smooth的副词是smoothly。
21．句意：最后，声音和音效被仔细地录制下来。此处需修饰动词“are recorded”，应用副词形式。careful的副词是carefully。
22．句意：演员为每个角色配音。此处表示“为”每个角色配音，应用介词for。
23．句意：他们使自己的语调与角色的情感相匹配。根据名词“tones”可知，此处需填形容词性物主代词作定语。they的形容词性物主代词是their。
24．句意：声音工程师还添加背景音乐和特效。此处需填名词作主语，表示“声音工程师”，且谓语动词add为原形，主语应为复数。engineer的复数是engineers。
25．句意：这是团队共同努力和辛勤工作的结果。固定搭配the result of“……的结果”，此处应用定冠词the。
