[Manuela]

I've taught both English Files and New English Files. I would recommend the latter, even though the old English Files were excellent books too.
The New English Files also have a CD ROM for students to practice on their computer. I'm really enthusiastic about this series of books and would gladly teach it again. I wish I had written it, it so much suits me. THere is also plenty of extra stuff to do with the students, in the teacher's book. There are games. THere are songs. There is everyday conversation vocabulary. I strongly recommend it.
