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.

The War of the Worlds, a Level 1 Reader, is A1 in the CEFR framework. Short sentences contain a maximum of two clauses, introducing the past simple tense and some simple modals, adverbs and gerunds. Illustrations support the text throughout, and many titles at this level are graphic novels.

The Martians are coming! They are burning houses and killing the people of Earth. How can the people stop them?
