The course for secondary students with enquiring minds. "World Class" is a four-level course for secondary students of English. "World Class 4" builds on and develops the approach established in "World Class 3". Each level of the course provides 90-100 classroom lessons. Key features: Builds on students' natural curiosity: theme-based modules offer a mixture of fantasy, everyday topics and interesting facts about the world. Encourages learner independence: a special introductory module teaches students how to learn. Expands vocabulary and improves dictionary skills: a mini-dictionary at the back of the Students' Book contains definitions of the most important new words in the course. Develops fluency: integrated skills work encourages all round fluency. Motivates students: active "Language focus" sections encourage students to discover for themselves how language works.
