Please correct the work:

Last year I went to Japan.  When I was there, I went to Disney World.  Japan was very scientific because Disney World's robot was walking and talking, and when you took a picture of it, the robot said cheese. I took a turn on the simulation ride. I watched a 3-d movie using VR glasses.  When the simulation ride made it seem like we were felling down, I felt surprised and scared. One day, after I went to Disney World and rode the simulation ride, I took a rest.  I was staying at a friend of the family's house. He had a dog. I was bored during that time. The dog's hair was very long and it was hot. The dog was panting so I gave the dog a haircut. I was surprised because Japan was very clean, no litter and no dog droppings.  I think Korea must try to make a clean country.
