Unit 4- Family

I just discovered that some fo the units contain recorded sound in which they read out the material. It is useful but very very slow for me, they repeat everything 2-4 times and it is impossible to navigate within the soundtrack.
The unit starts with quite complicated questions and answers out of the blue. The translation is there but I think it still requires background knowledge. After that they list a couple of family members. Later they list simple questions and answers, which is a little strange. There are some tasks which are supposed to be completed within the class or with the help of the teacher. There is a grammar part included but it has absolutely nothing to do with family. I do not really like this kind of structure.
All in all, this unit was ok but there were some parts which do not belong to the material it was supposed to present and many things could be added.
