ПОМОГИТЕЕЕЕЕ Task 1. Read the text and complete the sentences.

I like sport. It plays a great role in my activities. Most of all I like to play

basketball. I am the best player and often take part in different sport competitions.

Sometimes we win them but sometimes we lose. Basketball is a team game. It is

played in any season because it is an indoors game. It is played in a gym. But

sometimes you can see streetball - basketball in the open air. There are two baskets

in this exciting game and only one orange ball. Players must throw the ball to the

basket and get to it to score a goal. There are two teams with only five

players. Many people are keen on sport because it makes us healthy and help us to

be fit. When you play any sport game you are active and it helps you to burn many

calories. Basketball is an active game. It makes people be strong, healthy and

energetic. It is a game for everybody even for disabled people. To my mind any

sport is risky and dangerous. Basketball is risky too because every minute you can

break your arm or leg or get another problem with your health. I like playing

basketball most of all. And I am a basketball fan too. I enjoy watching matches on

TV and at the gym. I have been to the gym. It was the greatest game I have ever

seen.
