Consulting authoritative materials from Cambridge International Corpus and Cambridge Learner Corpus, the author places vocabulary into real scenes which provide practical and effective language materials for learners, making learning informative and interesting; in addition, the materials selected and form of layouts are helpful for preparation of PET, including all the themes of the exam as well as relevant vocabulary. Each unit proffers cases of speaking, listening, reading and writing for examinees to know the forms and difficulty of the test.
