Agricultural economics has undergone significant changes, driven by advancements in technology and shifts in consumer demand. Precision farming utilizes satellite imagery to enhance crop yields by analyzing soil and weather conditions. This allows farmers to make informed decisions about planting, watering, and harvesting, which in turn increase efficiency and reduce waste.

Another development is the rise of organic farming, which responds to consumer preference for sustainable products. Organic farming avoids synthetic pesticides and fertilizers, focusing on crop rotation, composting, and biological pest control. This practice has environmental benefits and creates niche markets for farmers.

Global trade also impacts agricultural economics. Nations depend on importing and exporting food to meet domestic needs and take advantage of international prices. However, this interdependency can lead to economic vulnerability when global supply chains are disrupted by political instability or natural disasters.

Innovations and global dynamics can also pose other challenges. Precision farming requires significant investment in technology, which can be prohibitive for small-scale farmers. Organic farming often yields lower outputs than conventional methods, complicating the balance between sustainability and food security. Additionally, reliance on global trade exposes countries to fluctuations in international markets, necessitating robust economic policies to manage these risks.

题干翻译 文章中 “enhance” 一词最接近的意思是:(A) 维持 (B) 模仿 (C) 预测 (D) 改善 分析 本题考查学术文章中的词汇同义替换,需结合 “enhance” 所在语境的语义逻辑,通过上下文关联推断词义。 定位信息 原文对应句:“Precision farming utilizes satellite imagery to enhance crop yields by analyzing soil and weather conditions.”(精准农业利用卫星图像,通过分析土壤和天气状况来 enhance 作物产量)。后文补充说明 “这能让农民在种植、灌溉和收获上做出合理决策,进而提高效率、减少浪费”,可见 “enhance crop yields” 与 “提高效率” 为顺承关系,语义偏向 “提升、改善”。 选项分析 A(维持):“维持产量” 与后文 “提高效率、减少浪费” 的积极效果矛盾,排除。 B(模仿):“模仿产量” 不符合 “通过技术分析优化农业生产” 的语境,无逻辑关联,排除。 C(预测):原文未提及 “预测产量”,且 “预测” 与 “利用卫星图像优化产量” 的动作无关,排除。 D(改善):“改善作物产量” 既符合 “技术提升生产效果” 的逻辑,也与后文 “提高效率” 形成语义呼应,正确。
