5–8 unknown words per 100 at CET-4 level. Looking each one up will stall you; this one wants glosses that appear in place.
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 870 of them.

In the garden all the apple-trees were in blossom. They had hastened to bring forth flowers before they got green leaves, and in the yard all the ducklings walked up and down, and the cat too: it basked in the sun and licked the sunshine from its own paws. And when one looked at the fields, how beautifully the corn stood and how green it shone, without comparison! and there was a twittering and a fluttering of all the little birds, as if the day were a great festival; and so it was, for it was Sunday. All the bells were ringing, and all the people went to church, looking cheerful, and dressed in their best clothes. There was a look of cheerfulness on everything. The day was so warm and beautiful that one might well have said: "God's kindness to us men is beyond all limits." But inside the church the pastor stood in the pulpit, and spoke very loudly and angrily. He said that all men were wicked, and God would punish them for their sins, and that the wicked, when they died, would be cast into hell, to burn for ever and ever. He spoke very excitedly, saying that their evil propensities would not be destroyed, nor would the fire be extinguished, and they should never find rest. That was terrible to hear, and he said it in such a tone of conviction; he described hell to them as a miserable hole where all the refuse of the world gathers. There was no air beside the hot burning sulphur flame, and there was no ground under their feet; they, the wicked ones, sank deeper and deeper, while eternal silence surrounded them! It was dreadful to hear all that, for the preacher spoke from his heart, and all the people in the church were terrified. Meanwhile, the birds sang merrily outside, and the sun was shining so beautifully warm, it seemed as though every little flower said: "God, Thy kindness towards us all is without limits." Indeed, outside it was not at all like the pastor's sermon.

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.
