Writing. Task 2. Read the story about life in the countryside. My name is Peter. I live in the countryside, in a cottage which is over

100 years old. The cottage is near a small village. I love living here because it's calm. There aren't many cars or busses, the streets are clean. You can go for a walk because there isn't any violence. You can even leave your doors open, nobody will steal anything

We know all the neighbours and at the end of the day, people get together at the main square and chat. We go to bed early, as there isn't much to do in the evening. There isn't any disco, theater or cinema. We also don't have a museum or a youth club. However the children can play in the streets or in the fields and they can have animals.

You can sleep very well because there is no noise. You can hear the birds singing or the rain pouring. The air is pure and cool and you can see millions of stars. It is a bit difficult in winter. Sometimes it snows a lot and then we are isolated for a few days. Despite this I like living in the countryside.

Answer the questions. Write answers

1. Where does Peter live? 2. Where is the cottage?

3. Why does Peter love living in the countryside?

4. Why is it easy to go for a walk?

5. What do people do at the end of the day?

6. When do people go to bed?
