some thought about the couse

I want to wirte something about the course.The name is Multimedia music technology.The teacher is Dafu_Lai.I chose the course because it connect with computer,and I think I don't hate music.But I think maybe I was wrong to chose the couse at the begainning of the first class. because I found that Mr Lai said English in the first half class.But I am not good at English,I can't understand many things he said.
He taught us building our blogs and HTML language in the first class. I was intersted in these.so I decide to have the class.In the next several classes ,I found Mr Lai said more and more chinese.sometimes you can't heared any English in a class. He taugth us some knowledge about music and using some softwares.I really learn many things.But I must to say sorry to Mr lai,because I always didn't finish homework on time.and I think my homework is not good.
