Hi, do you know anything about inline skates? 
Nope! I here to learn.From what I know ,skates are supposed to be flat boards slides on a slope ,I hope I'm right ? Lol!
Haha, well, there are many different kinds of skates. The ones I used when I was a kid were inline skates called rollerblades. I rode around on them all the time.
Roller blades are what ? Is it a type of skate?
Roller blades are a type of inline skate that you use to "roll" or "skate" along the road or sidewalk. They are used in roller hockey or for fun at a skating rink.
Interesting ! Do you know the earliest history of skates ,especially the ice skating?
No, I do not know the earliest history of ice skating. I did hear that ice skates may have been used by vikings almost 10,000 years ago. They were made of animal bones and leather.
Good and fine, how about the Olympics ,is skating part of the sporting event?
