Heavy going at CET-4 level. Not unreadable — just not readable the look-every-word-up way.
Coverage = the share of words in the text you already know. The research gives two lines: 98% before independent fluent reading is realistic, 95% for the instructional level that needs support (Hu & Nation, 2000). Proper nouns are not counted as unknown — recognising that it is a name is enough; this book has 700 of them.
Advanced — read it with glosses. 351,444 words in total; at 150 words a minute for a non-native reader, about 39 h 3 min to finish. Average sentence length 13.9 words. Reaching 95% coverage on this book (the floor for readability) takes roughly 16,500 word families.
The opening of The Brothers Karamazov, word for word. Tap any word you don't know and its meaning here appears beside it — no sign-up, tap as often as you like.
Alexey Fyodorovitch Karamazov was the third son of Fyodor Pavlovitch Karamazov, a land owner well known in our district in his own day, and still remembered among us owing to his gloomy and tragic death, which happened thirteen years ago, and which I shall describe in its proper place. For the present I will only say that this “landowner”—for so we used to call him, although he hardly spent a day of his life on his own estate—was a strange type, yet one pretty frequently to be met with, a type abject and vicious and at the same time senseless. But he was one of those senseless persons who are very well capable of looking after their worldly affairs, and, apparently, after nothing else. Fyodor Pavlovitch, for instance, began with next to nothing; his estate was of the smallest; he ran to dine at other men’s tables, and fastened on them as a toady, yet at his death it appeared that he had a hundred thousand roubles in hard cash. At the same time, he was all his life one of the most senseless, fantastical fellows in the whole district. I repeat, it was not stupidity—the majority of these fantastical fellows are shrewd and intelligent enough—but just senselessness, and a peculiar national form of it.

Computed by Readii from the public-domain text (updated 2026-10-21), not estimated by hand. The Readii reading level is our own scale, anchored on unknown-word density; it is not the same system as Lexile or AR and does not convert directly. Unknown words are measured against the CET-4 ∪ Gaokao lists, so this is difficulty for a Chinese-speaking learner, not a native-child reading level.
