This is a professionally made ESL site from the state of California.Each lesson  contains workplace skills with appropriate grammar and vocabulary. You need Real Player to listen as you read the paragraph, etc. Lesson 2 is appropriate for our Level 4. Lesson 3 & 4 are appropriate for Level 5.Some computers will get a message ("Your request file does not exist") when they try to use Real Player for the listening portion. If that happens, the students can read it without listening.
