I found this one day about a year ago on the internet and was able to download them to use. I find these are realy great for helping people learn to listen and speak English. There is very little about grammar which makes it nice for students because many of them do not like to tudy the grammar. But they do enjoy the activities in these levels. They are progresive in learning. I have made them available here for anyone to download and use.
