雅思词汇：高级（约 7 分以上）
本页列出词库中的高级词汇，大致对应 CEFR C1–C2、雅思 7 分及以上。这些是 empirical、biodiversity、rehabilitation、methodology 等使用频率较低、含义更精确的词。它们经常出现在雅思阅读文章中；在写作和口语中用得恰当，则能帮助你冲击高分段。
在这个级别，精确比数量更重要。考官不会因为生僻而加分，而是奖励自然、准确、搭配和文体都恰当的用词。一个选得好的动词，如 facilitate 或 inhibit，往往比满是复杂词汇的句子更有效。高级词汇通常带有正式色彩，所以要注意语域：obtain 适合作文，口语中说 get 就很自然。
本词表主要来自学术词组以及各主题词组中较专业的词汇，其中很多出自新学术词表（New Academic Word List），该词表基于大量大学文本统计而成。在阅读中快速识别这些词是一大优势，有时一个关键词的含义就决定了一道题的答案。
使用建议：如果目标是 7 分或更高，每天新学十到十五张卡片。每个新词第二天进行隔夜复习，之后随着记忆巩固间隔逐渐拉长。留意每张卡片的词性和例句，遇到难记的词就写下自己的笔记——笔记保存在你的设备上，会随卡片一起出现。与其粗略地记很多高级词，不如扎实地掌握少一些。
级别标签是我们根据 CEFR 标注和词频做出的估计，仅作学习规划参考，并非雅思官方标准。
