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 作者为什么提到 “政治不稳定或自然灾害”?(A) 指出依赖全球贸易可能产生负面后果的情况(B) 提供对农业经济学影响微不足道的因素示例(C) 强调有机农业的重要性(D) 证明技术进步如何解决问题 分析 本题考查 “论据与论点的逻辑关系”,需先明确 “政治不稳定或自然灾害” 所在句子的核心论点,再判断该短语作为论据的作用 —— 支撑论点或举例说明。 定位信息 原文对应句:“However, this interdependency can lead to economic vulnerability when global supply chains are disrupted by political instability or natural disasters.”(然而,当全球供应链因政治不稳定或自然灾害而中断时,这种相互依赖会导致经济脆弱性)。前半部分论点为 “依赖全球贸易(相互依赖)会导致经济脆弱性”,“政治不稳定或自然灾害” 是导致 “供应链中断” 的具体原因,进而触发 “经济脆弱性”,属于 “负面后果的具体触发情况”。 选项分析 A(指出依赖全球贸易可能产生负面后果的情况):该短语明确了 “依赖全球贸易(相互依赖)” 引发 “经济脆弱性(负面后果)” 的具体场景,与论点逻辑完全匹配,正确。 B(提供影响微不足道的因素示例):原文中该因素会 “中断供应链、导致经济脆弱性”,显然是 “有显著影响” 的因素,选项与原文矛盾,排除。 C(强调有机农业的重要性):该内容属于 “全球贸易” 部分,与有机农业无关,排除。 D(证明技术进步如何解决问题):该内容与 “技术进步(精准农业)” 无关联,且未提及 “解决问题”,排除。
