We are using more plastic than ever before. It is cheaper, stronger, and more useful than lots of materials that were used in the past. But where does it come from? And what impact is it having on our planet? Penguin Readers is a series of the best new fiction, essential non-fiction, and popular classics written for learners of English as a foreign language. Beautifully illustrated and carefully adapted, the series introduces language learners around the world to the bestselling authors and most compelling content from Penguin Random House. The eight levels of Penguin Readers follow the Common European Framework and include language activities that help readers to develop key skills. Plastic, 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 models, adverbs, and gerunds.
