Chapter 7 of The Underground City by Jules Verne holds 112 sentences, grouped into 23 reading sections of at most 5 sentences. The text is the public-domain source, unabridged, and the chapter records which sentences cover which part of the work so that nothing is dropped. Every word can be tapped for its pronunciation and dictionary entry.

What does chapter 7 of The Underground City contain?

Chapter 7 holds 112 sentences of The Underground City, unabridged, divided into 23 reading sections.

This page carries chapter 7 of The Underground City by Jules Verne exactly as it stands in the public-domain source edition, without abridgement. It runs to 112 sentences, grouped into 23 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 7 of The Underground City?

Work through the 23 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 23 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 7 be read aloud to me?

Yes — every sentence and every individual word in chapter 7 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
