2026 考研英语易错题：长难句逻辑关系辨析

阅读以下段落，回答问题：

While renewable energy sources like solar and wind have gained significant traction in recent decades, their integration into global power grids remains fraught with challenges. Although technological advancements have reduced the cost of solar panels and wind turbines, the intermittent nature of these energy sources—dependent on weather conditions—creates instability in electricity supply. Moreover, the lack of efficient energy storage solutions exacerbates this issue, as surplus energy generated during peak production cannot be easily stored for later use. Consequently, many countries continue to rely on fossil fuels as a backup, undermining efforts to reduce carbon emissions.

The word “Consequently” in the passage indicates a relationship of:
A. Contrast
B. Cause and effect
C. Addition
D. Emphasis

解析：
本题考查对段落中逻辑连接词所表达关系的识别，需结合上下文语义逻辑分析。

• 前文先指出可再生能源虽获发展但电网整合存在挑战，接着具体说明两大问题：能源供应受天气影响不稳定，且缺乏高效储能方案加剧这一问题。
• “Consequently” 引出的内容 “许多国家继续依赖化石燃料作为备用能源，削弱减排努力” 是前文所述问题导致的直接结果。这种 “问题阐述 — 结果呈现” 的逻辑符合因果关系特征，故选项 B 正确。
• 干扰项 A（对比）需通过 “however”“while” 等词体现，此处并非对比不同事物；C（补充）常用 “furthermore”“in addition” 等，强调同类信息的叠加；D（强调）多通过 “indeed”“particularly” 等词突出重点，均与 “Consequently” 的逻辑功能不符。

答案：B
