Writing about My Neighborhood

[postlink] http://uknow-iknow.blogspot.com/2016/08/writing-about-my-neighborhood.html[/postlink]

              Hello my name is OUTDOM. Nowadays I live in Siem Reap, and study at USEA (University of South-East Asia). For second semester of first year, my teacher asked me to writing about my neighborhood area. In my neighborhood area there are many area such as Hospital, School, Sport Club, Police station, Pagoda...

              My school is East of my home and also very good place in there, because it so nice and it's fresh air place. My friends  and my neighbor usually in there on evening, because they're wanna get fresh weather for make their feel to better. However, in my school is good environment. In front of my house there is a police station. Near of police station there is a lake that have many person go to bathing in there everyday. Sometime they're get the water in there to use for their living. In the west of my house maybe 1km there is a pagoda. The way to pagoda is very difficult for go. So don't have many people go there.
