Ladies and gentlemen,
Welcome to our English Corner. This Corner was set up three years before. Every Sunday morning, students from different schools gather around here. Many college students or some foreigners often join us. We practise spoken English by talk about everything we are intrersted. We also exchange our experience in English study. We all have a good time here. Thousand of people have been here when it was set up.
We think that they have learned a lot by taking part in activities here. It is a really supplement to our English class and it is welcome by students, their parents and teachers.
