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 324 of them.
Advanced — read it with glosses. 84,943 words in total; at 150 words a minute for a non-native reader, about 9 h 26 min to finish. Average sentence length 17.1 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 The Scarlet Pimpernel, 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.
A surging, seething, murmuring crowd of beings that are human only in name, for to the eye and ear they seem naught but savage creatures, animated by vile passions and by the lust of vengeance and of hate. The hour, some little time before sunset, and the place, the West Barricade, at the very spot where, a decade later, a proud tyrant raised an undying monument to the nation’s glory and his own vanity.
During the greater part of the day the guillotine had been kept busy at its ghastly work: all that France had boasted of in the past centuries, of ancient names, and blue blood, had paid toll to her desire for liberty and for fraternity. The carnage had only ceased at this late hour of the day because there were other more interesting sights for the people to witness, a little while before the final closing of the barricades for the night.

Ordered by unknown words per 100. Lower reads easier; to step up a level, pick a higher number.
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.
