以四级词汇量,这本在『教学级』难度区 —— 读得动,但需要辅助。研究里这个区间恰好也是最容易进入心流的地方。
覆盖率 = 正文里你已经认识的词占多少。研究里的两条线:98% 才谈得上自主流畅阅读, 95% 是需要辅助的教学级(Hu & Nation, 2000)。人名地名不计入生词——认出它是个名字就够了, 这本书里有 167 个。
四级 + 辅助能读完。全书 91,721 词,按非母语者每分钟 150 词估算,读完约需 10 小时 11 分。 平均句长 23.1 词,属于长句偏多的那一类,理解负担主要来自句子结构而不只是生词。 想让这本书的覆盖率达到 95%(读得动的下限),大约需要 11,750 个词族。

From the old and pleasantly situated village of Mayenfeld, a footpath winds through green and shady meadows to the foot of the mountains, which on this side look down from their stern and lofty heights upon the valley below. The land grows gradually wilder as the path ascends, and the climber has not gone far before he begins to inhale the fragrance of the short grass and sturdy mountain-plants, for the way is steep and leads directly up to the summits above.
On a clear sunny morning in June two figures might be seen climbing the narrow mountain path; one, a tall strong-looking girl, the other a child whom she was leading by the hand, and whose little checks were so aglow with heat that the crimson color could be seen even through the dark, sunburnt skin.

按每百词生词数排的。数字小的读起来轻松,想跳一档就往数字大的挑。
数据由 Readii 用公版原文自动计算(2026-07-23 更新),不是人工估的。 「Readii 阅读级」是自研刻度,锚在生词密度上,与蓝思(Lexile)、AR 不是同一套体系,不可直接换算。 生词判定基准为四级 ∪ 高考词汇表,因此这里的难度是对中文母语学习者而言的,不是母语儿童的分级。
