Leave it to the French to make a sweet site about English. This comes from the UniversitÃ© de Franche-Comte. It is filled with interactive quizzes and practice sessions in a variety of reading and language arts areas. Click on any of the “Interactive English Excercises”. I tooled around on a few of them and they give good explanations of the concepts and great exercises to practice them. This would be great thing for advanced (or lower level) students to work on while the teacher gives more individualized instruction to other students.
