A roadmap for usage-based language acquisition research 为"基于使用的语言习得"研究绘制的路线图
Building on Heike Behrens's pioneering corpus work, Römer-Barron sketches the road ahead for usage-based language acquisition research along four routes — data, methods, research priorities, and theory — and urges the field to consolidate its many strands under one shared "usage-based research habitus" rather than minting ever more labels.
作者承接 Heike Behrens 的开创性语料库工作，沿数据、方法、研究重点与理论四条路径，为"基于使用的语言习得"研究勾画前路；并主张本领域应在共享的"基于使用的研究习性"之下整合其众多分支，而非不断制造新标签。

Behrens's Leo Corpus is held up as the kind of resource the field needs more of — and which is virtually missing for L2 learners.
Behrens 主持建设的 Leo 语料库，被视为本领域亟需更多的那类资源——而对 L2 学习者而言，这类资源几乎是空白。
Figures from the Leo Corpus as reported in the chapter (German L1; oversight by Behrens). The gap: large, dense L2 acquisition corpora remain rare to non-existent.
数据为本章所述 Leo 语料库（德语母语，Behrens 主持）。缺口在于：大型、密集的 L2 习得语料库仍属罕见乃至空白。
Frequency drives acquisition — but the chapter argues other distributional measures may be equally or more powerful. The bars show how the proposed emphasis shifts (illustrative weighting, not from numerical data in the paper).
频率驱动习得——但本章主张，其他分布度量或许同等重要、甚至更具解释力。柱状图示意所倡导的重心转移（为示意性权重，非论文中的数值数据）。
The closing vision: not new labels, but unification under Ortega's "usage-based research habitus." Nick Ellis's roll-call of the converging fields:
收束的愿景：不是新标签，而是在 Ortega 的"基于使用的研究习性"之下整合。Nick Ellis 点名的汇聚学科有：
A short, agenda-setting postface — roughly a 25–30 minute read. It moves through five sections, each posing a "where to next?" Follow the path; the watch-points flag what each section is really doing.
这是一篇短小的、设定议程的"后记"，通读约 25–30 分钟。全文经由五个小节展开，每节都在追问"下一步去哪"。沿路径前行，"关注点"提示每节真正在做的事。
The chapter assumes fluency in the usage-based toolkit. These entries unpack the core terms and the people whose work the agenda builds on.
本章默认读者熟悉"基于使用"的工具箱。下列条目拆解核心术语，并介绍这份议程所依托的学者。
Six readerly responses — not summaries, but places where the agenda invites pushback, sharpening, or a different research design.
六则读后回应——非复述，而是这份议程值得质疑、推敲或另作研究设计之处。
