阅读理解与推测填词——CEFR 5
阅读推测填词就是 IELTS 和 TOEIC 真题阅读部分常见的“阅读短文，选词填空”题型——与简单填空不同的是，空格位于整篇短文之中，你必须读懂上下文的意思，才能推断出最合适的单词。被遮住的词始终是 CEFR 5 阅读文章的关键词，而不是随意拼凑的句子。
示例题
语言模型与数据难题
Large language models improved for years by an unglamorous route: more data and more computation. Both inputs are now running into limits of a different kind.The supply of high-quality human text is ＿＿ and largely already used.Synthetic text can extend the supply, but training a model mainly on its own output degrades it. Researchers describe the failure mode as a narrowing: rare constructions disappear first. Curated data therefore now carries a price, and licensing deals have followed. This alters the competitive landscape more than any technical advance. A laboratory without an archive, a publisher or a platform must buy access from one. Open-weight models complicate the picture in a useful way. They are usually behind the frontier, yet good enough for most applications and far cheaper to run. For a hospital or a ministry, auditability may matter more than the last percentage point of accuracy. Evaluation remains the weakest part of the field. Benchmarks leak into training sets, after which a high score proves little. Serious deployments now rely on private test sets and on measured failure rates in real use. That is slower, unfashionable and the only evidence worth acting on.

FAQ
怎样推测缺失的单词？
通读空格周围的整段文字（不只是含有空格的那一句），再根据上下文推断出最合适的关键词——这正是 IELTS 和 TOEIC 真题中常考的推理阅读技能。
被遮住的词是生僻难词吗？
不是——它是 CEFR 5 阅读文章词汇表中的关键词，也就是文章的重要单词，不是生僻词，也不会超出你的级别。
