Dear Bill,

I’m very happy to know you’ll come and study in our school. It’s a pleasure for me to give you some introduction.

Our school is a beautiful garden school. Entering the school gate, you will see a main road leading straight to the teaching building in the middle of our school. On each side of the road there is a flowerbed, where different kinds of flowers are in bloom. On your left, behind the flowerbed is the lab building. It is where we do all kinds of experiments. The office building is on the other side. Behind the teaching building is a playground, to the west of which there is a swimming pool. We have also planted many trees in our school. Now they are growing very well. I am sure if you come you will like it.

          Hope to see you soon.

                                         Yours,
