The Teacher's Resource File contains all the material included in the Student's Book with interleaved Teacher's Notes.
It also contains a complete photocopiable assessment programme, ideas for mixed-level classes and extra photocopiable activities. At the end of each lesson there is always either a Reinforcement or Extension activity which gives additional practice or extends the theme of the lesson.
The credit for the pages from the Student's Book goes to lust4life , the uploader of the World Club 2 SB.
