BBC - Keep your English up to date: 7 series

The English language is permanently evolving and developing. New words and expressions are coined and existing words change their meaning as society, culture and technology progress.
Some of the world's foremost experts on language have recorded short talks on some of these words and expressions that have recently made it into the language, if not necessarily into dictionaries.
Each unit contains the text of the talk, audio and a lesson plan for teachers.
The lesson plan contains teacher's notes, worksheets for students as well as a key to the answers.
The file includes 7 series of lists of words.
