学校的welcome to our school.In the past few months,a lot of changes have taken in our school .Now let me be your guide to show you around.
Take a look at that brand new buiding over there,it was our new school buiding and it has a lot of advance equipment in it.Each floor has a dependent toilet,so it is quite convienent for us teachers and students.
Now,we are standing on a new playground,it looks like a big circle and we do morning excercise here every morning at school.and it is also a good place to do some sports.
The old one has been changed into a library.
You must have noticed that there are a lot of trees around our school.Yes,all of them were planted by us in spring.Because of them,we have fresh air every day and we can enjoy it when studying.
