《变形记》难度分析:四级词汇量能读吗?

The Metamorphosis · 弗兰兹·卡夫卡 Franz Kafka · 1915 年

要使点劲

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。

不同词汇量能覆盖多少

最常见 1000 词 76.3%
最常见 3000 词 88.3%
最常见 5000 词 92.3%
最常见 10000 词 95.6%
四级 + 高考词汇 95.8%

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 26 个。

这本书适合谁

四级 + 辅助能读完。全书 22,012 词,按非母语者每分钟 150 词估算,读完约需 2 小时 27 分。 平均句长 26.5 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 8,750 个词族。

One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.

“What’s happened to me?” he thought. It wasn’t a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the table—Samsa was a travelling salesman—and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer.
