Well, actually, there is no MP3 in the first volume of English for the third grade of primary school in Hebei Education Publishing House. I have the second volume because I recorded it on tape myself. At first, it was for my daughter. Later, when I saw someone looking for it online, I posted it online for convenience. But my daughter's first tape is broken, so she can't make MP3, only the second one. When my daughter was in the fourth grade, I issued the first volume of the fourth grade.
