C (2025年全国卷II) When Sonja Detrinidad opened her online shop selling houseplants, she didn’t have high hopes for it. But the opposite happened: She was flooded, shipping out 1,200 orders in June of 2020 alone. In the past year, Detrinidad sent out more than 70,000 plants. Her success is just one example of increased time at home leading to an explosion in the houseplant industry.  “Plants are in fashion right now,” says Dr. Melinda Knuth, a researcher from the University of Florida. “People who live in plant-rich environments report a higher life satisfaction rating,” she says. “Adding more nature to our environment can change our mood and how we think.” Plants can improve our state of mind in a few ways but the biggest is by decreasing our level of cortisol, the stress hormone (激素) in our body.  “Students who are around plants perform better academically than students who are in a classroom without plants,” says Knuth. “This productivity also translates into the workplace for adults. Our study showed that there was a 30% decrease in sick leave for people who were in plant-rich workplaces.”  If you’re among the groups of people who are enjoying the mental and physical health benefits of surrounding yourself with plants, don’t beat yourself up if one (or a few!) doesn’t make it. “Doctors practice medicine and lawyers practice law and you should allow yourself the practice it takes to sustain a plant. Tending to plants is an exercise in patience and learning. Be invested in taking care of it, but if it dies, go get another one,” Detrinidad says.

Part Key content & logic Part 1 现象（引言）——展示“是什么” Part 2 技术/机制（主体1）——解释为什么 Part 3 应用/影响（主体2）——说明“在哪里用/有什么效果” Part 4 展望/启示（结论）——指向“未来该怎么做/有何启示” Reading for writing technique The collaboration between farming and technology has given rise to precision farming, an approach that equips farmers with the tools and data they need to make reliable decisions with remarkable accuracy.（Para.1） 1. Definition(下定义) When we think of farming, the first image that springs to mind might be of a farmer working in a field under the baking sun. Face covered in sweat, he might be walking through the field, carefully checking his crops before deciding what needs to be done. In modern times, however, this deep-rooted image of a traditional farmer is being changed.（Para.1） While such applications are of enormous benefit, precision farming can reach a much higher level with the application of artificial intelligence. （Para.4） 2. Comparison & contrast (作比较) Reading for writing technique 1). These can be achieved with a combination of information-gathering tools like sensors, satellites and drones, and advanced technologies such as artificial intelligence (AI). (L14-15) 2). Soil sampling, an example of precision farming in its most fundamental form, provides an accurate means for farmers to tend their crops.（L22-24） 3. For instance, if soil is found to be poor in nutrients, not only do farmers know what fertilizer is needed, they can also calculate the exact amount.(L28-30) 4). For example, cotton farmers use drones with AI technology to carry out specialized tasks: they precisely remove the cotton plants’ leaves by spraying chemicals only on the parts that need them. （L40-42） 3. Exemplification(举例) Reading for writing technique Please choose one sentence and rewrite it by using exemplification: With massive amounts of data gathered, processed and analysed in real time, farmers are able to give the best possible care to the crops that most need it. (Para 2) AI-controlled machines can now plant and harvest more crops at faster speeds than humans ever could. (Para 4) 3. This technology is ideal for crops that require delicate handling. (Para 4) With massive amounts of data gathered, processed and analysed in real time, farmers are able to give the best possible care to the crops that most need it — for example, they can identify a wheat field suffering from diseases and apply fertilizer only to that specific area. AI-controlled machines, like autonomous tractors and robotic harvesters, can now plant and harvest more crops at faster speeds than humans ever could. This technology is ideal for crops that require delicate handling, such as strawberries, grapes and cotton. Reading for writing technique 1). This evolution is having a positive impact on farming, while also providing better solutions to the world’s pressing food problems. 2). While such applications are of enormous benefit, precision farming can reach a much higher level with the application of artificial intelligence. 3). Thanks to precision farming’s close relationship with technology, the farming industry’s capabilities can develop even further. 4. Cohesion between paragraphs by using linking sentences What is the function of words in red? 表递进 表转折 表因果 承上启下；总结前文，引出下文。 Reading for writing technique Nowadays, humanity is facing possible food shortage as good farmland decreases globally. Fertile soil is important for farming, but innovative soil-free farming methods may provide solutions. __________________________. A Japanese inventor developed a thin film made of hydrogel (水凝胶薄膜) that can absorb plenty of water and nutrients. It can be placed on any flat surface. The plants grow on top of the film and their root systems spread out like a fan. The hydrogel gives the plants all they need and the film stops bacteria and viruses from infecting the plants. B2 1. One such method is film farming. 2. Film farming is one example. 3. Take film farming for instance. 4. A promising example is film farming. Reading for writing purpose 1. Why does the author introduce precision farming? The author introduces precision farming to show how the traditional image of farming is being changed by technology, and highlights the role of technology in transforming agriculture. Reading for writing purpose 2. What does precision farming aim to do? It aims to improve food production and conserve the environment by reducing a farm’s input and increasing its output. Reading for writing purpose 3. So what’s the target of precision farming? In precision farming, the target is not simply higher yield, but a balance between feeding the world and caring for the earth. Technology is best when it brings people and nature together. Reading for details Para. 1: What is the deep-rooted image of a traditional farmer? What cause this image to be changed? What does precision farming aim to do? Reading for details the deep-rooted image: a farmer working in a field under the baking sun, face covered in sweat. The deep-rooted image changed by the collaboration between farming and technology which has given rise to precision farming It aims to improve food production and conserve the environment by reducing a farm’s input and increasing its output. Traditional farming has been changed by the advent of modern technology/the wave of innovation. n. 出现 n. 创新 This latest wave of innovation offers farmers information that is more detailed, measurements that are more accurate and solutions that are more effective. These can be achieved with a combination of information-gathering tools like sensors, satellites and drones, and advanced technologies such as artificial intelligence (AI). With massive amounts of data on the state of their farmland gathered, processed and analyzed in real time, farmers are able to give the best possible care to the crops that most need it at the most appropriate time and put their resources to the best use. how to gather information: the significance of accuracy and effectiveness make the best/most of; make full use of Para. 2: What does the advent of modern technology offer to farmers? Para. 2: What can farmer do with the massive amounts of data? Farmers are able to: give the best possible care to the crops that most need in real time put their resources to the best use minimize potential threats to the environment by reducing unnecessary chemicals (an added bonus) Para. 3: What are the different application capabilities that precision farming has? How does the author explain the different application capabilities? What do you think the phrase “the big picture” in Line 26 refer to? 1. The different application capabilities : monitoring, diagnosing, identifying and targeting. 2. By using the example Soil sampling: field sensor data library check the soil’s moisture, nutrient levels etc. the big picture of the soil is revealed “The big picture” refers to all the detailed and accurate information about the soil, such as its nutrient levels, moisture, temperature, pH levels and water requirements. Based on all the information, farmers are able to make better decisions about farming. para4 What are the benefits of the application of AI in farming machines? What idea does author want to support by using the example of cotton? Benefits: AI does contribute to increased crop yields as well as simplified crop tracking, harvesting and processing AI-controlled machines can plant and harvest more crops at faster speeds computer vision can distinguish weeds from crops Algorithms based on data gathered by sensors, drones and satellites can work out site-specific management of the crops 吀愀欀攀 䴀攀 䠀漀洀攀Ⰰ 䌀漀甀渀琀爀礀 刀漀愀搀 䨀漀栀渀 䐀攀渀瘀攀爀 匀漀渀最猀 伀昀 䠀漀瀀攀 䄀渀搀 䘀爀攀攀搀漀洀, track 34, disc 2 EASY LISTENING 188980.42 $
