Dear editor,
My name is called Zhang Hong. I am a middle school
student. When I go to the school every day, I can see a lot of
sellers outside around our school walls, sell vegetables, fruits,
fish, meat and so on. Some even make dishes in the opening air.
They often shout at the top of their voices in order draw the
passers-by's attention. We could hear the noises in the classroom
and cannot concentrate on our lessons. Beside,they also make
the streets dirt, smelly and crowded. What a shame!
How we want to get the situation improved or have our
lessons in a quiet place! That's how I write to you for help!
