2026 考研英语易错题：观点态度判断辨析

阅读以下段落，回答问题：

The growing popularity of plant-based diets has sparked widespread discussion about their environmental and health impacts. Advocates emphasize that reducing meat consumption lowers greenhouse gas emissions and decreases the risk of chronic diseases like heart disease and diabetes. They often reference studies showing that well-planned vegan diets can provide all essential nutrients. However, nutritionists caution that improper substitution of animal products may lead to deficiencies in vitamin B12, iron, and omega-3 fatty acids. Additionally, critics note that large-scale production of plant-based meat alternatives relies heavily on monocropping, which can deplete soil nutrients and reduce biodiversity.

The author’s attitude toward plant-based diets can best be described as:
A. Unconditionally supportive
B. Mildly opposed
C. Objectively balanced
D. Strongly skeptical

解析：
本题考查对作者整体态度的准确判断，需通过分析文中观点的呈现方式来推断。

• 段落首先阐述支持者对植物性饮食的积极看法，包括环保效益和健康价值，并提及相关研究依据；随后用 “However” 转折，引入营养学家的担忧（营养缺乏问题）和批评者的观点（替代食品生产的环境问题），呈现了不同立场的合理依据。
• 作者未对任何一方观点表示明确认同或否定，而是客观平衡地展示了植物性饮食的优势与潜在问题，符合选项 C “Objectively balanced”（客观平衡）的特征。
• 干扰项 A（无条件支持）和 B（轻微反对）均片面强调某一方观点；D（强烈怀疑）与文中对支持者观点的客观陈述不符，作者并未流露明显的怀疑态度，仅呈现争议焦点。解题关键在于识别作者是否保持中立立场，避免被单一观点误导。

答案：C
