Task 1.
Read the story and mark these statements as true (T) or false (F).
School life in Kampala.
Today I’m going to tell you about a day in the life of a primary school in Kampala. Kampala is the capital of Uganda. Uganda is an African country and schools here are very different from European schools.
It’s 7 a.m.in the morning. Children are now coming from everywhere. They are wearing uniforms, some have a container of food for the lunch break.
It is 7.30 and lessons begin. There are no textbooks for younger classes, they learn letters and numbers listening to their teacher. But they are lucky – these children have a blackboard in their classroom. Many schools do not have blackboards.
It is lunch break now and those who have food and drink bring it out of their backpacks. Some children have a few cents to buy a sandwich and a drink. Others simply sit there hoping that those who brought something would share it with them. It is late afternoon in Kampala, children have returned home. Most children do not have much time to play because they have to help their parents around the house. They do not have any toys at home, there are no books to read for pleasure. Few homes have TV. Kids go to bed early, many of them feeling hungry but hoping for a better day tomorrow.
