My Best Friend

I have many friends. I like my friends. When we gather, we play computer games, chat and make lots of noise. I like noise.

To my mind, people should have many friends as possible, because if you have not friends, you just become very dull and boring person. It is fine when you have friends, who are able to understand you and support and help in difficult situations.

We have much in common and we enjoy communicating with each other.

One of my friends is Sergey. He is thirteen. I can say that he is a good guy. He is a schoolboy. He wants to be a businessman like his father. He studies well, but he is not a hardworking person.

When we gather together we like to play computer games, to watch new movies and discuss them. His favorite subject at school is Maths. He is keen on Maths. I guess he might become a great mathematician, but he wants to be like his father.

We are friends for a long time. We trust each other. We have some personal secrets. I can tell him about my troubles and he always helps me, if he can.

I’m happy to have such a good friend as Sergey.

Write True or False according to the text.

People must have a lot of friends. _____________

Sergey is good at History. _____________

Sergey always helps me. ______________

Friends support you. ______________

I can turn to my friends for help. _______
