Penguin Readers is an ELT graded reader series for learners of English as a foreign language. With carefully adapted text, new illustrations and language learning exercises, the print edition also includes instructions to access supporting material online. 

Titles include popular classics, exciting contemporary fiction, and thought-provoking non-fiction, introducing language learners to bestselling authors and compelling content. 

The eight levels of Penguin Readers follow the Common European Framework of Reference for language learning (CEFR). Exercises at the back of each Reader help language learners to practise grammar, vocabulary, and key exam skills. Before, during and after-reading questions test readers' story comprehension and develop vocabulary. 

Tess of the D'Urbervilles, a Level 6 Reader, is B1+ in the CEFR framework. The longer text is made up of sentences with up to four clauses, introducing future continuous, reported questions, third conditional, was going to and ellipsis. A small number of illustrations support the text. 

When Jack and Joan Durbeyfield learn that their ancestors were the d'Urbervilles - a rich and well-known family - they hope it will make their lives better. They send their eldest daughter, Tess, to introduce herself to some "relatives". There, Tess meets Alec d'Urberville, who immediately notices her beauty. The terrible event that follows changes her life forever.
