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 485 of them.
Advanced — read it with glosses. 28,795 words in total; at 150 words a minute for a non-native reader, about 3 h 12 min to finish. Average sentence length 16.9 words. This book is heavy on rare, archaic and invented words: even 25,000 high-frequency word families will not reach 95% coverage — its difficulty is not in the common vocabulary.
The opening of Just so stories, 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.
IN the sea, once upon a time, O my Best Beloved, there was a Whale, and he ate fishes. He ate the starfish and the garfish, and the crab and the dab, and the plaice and the dace, and the skate and his mate, and the mackereel and the pickereel, and the really truly twirly-whirly eel. All the fishes he could find in all the sea he ate with his mouth--so! Till at last there was only one small fish left in all the sea, and he was a small ‘Stute Fish, and he swam a little behind the Whale’s right ear, so as to be out of harm’s way. Then the Whale stood up on his tail and said, ‘I’m hungry.’ And the small ‘Stute Fish said in a small ‘stute voice, ‘Noble and generous Cetacean, have you ever tasted Man?’

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.
