| 句型类别 | 引导词示例 | 应用场景 |
|---|---|---|
| 状语从句 | because/although/if | 因果关系论证 |
| 宾语从句 | that/whether | 观点转述表达 |
| 同位语从句 | that | 概念解释说明 |
在学术写作中，恰当使用原因状语从句能显著增强论证力度。例如环保主题中可表述为：Environmental protection should be prioritized, as ecological balance directly affects human survival.
While technological advancement boosts productivity, it may simultaneously exacerbate social inequality. 这种句式结构特别适合讨论科技发展的双刃剑效应。
建议考生在日常练习中建立句型应用档案，按照"社会问题-教育领域-科技发展"等高频话题分类整理。例如讨论教育公平时可运用：What requires urgent attention is the inequitable distribution of educational resources.
定期进行句式改写训练，将简单句升级为包含定语从句的复合句：
原句：Many countries face environmental problems.
升级句：Numerous nations, particularly those undergoing rapid industrialization, are grappling with severe ecological challenges.
