I am sorry for description of a site to have supported only Japanese, although you visited my site. Here is some sound files which I translated from the collection of my SP disk. If you are interested in them, I will think that you can enjoy them. I can understand, if it is the document written in easy English. And since my wife has experience which carried out studying abroad for three years in Boston, the United States, probably she will help that I read your mail. I am very glad if you give me mail for the comment which heard the sound files in easy, easy English.
