8 Read the announcement about a sports club. Are these statements True (T), False (F) or is the informationNot Mentioned (NM)?The Little Olympic Club The Little Olympic Club is a sports club with a difference. We are all good athletes and we want to be winners in the Olympic Games. We are all between 6 and 11 years old and we live in areas of our town where there are no sports centres or clubs. Our parents don’t have a lot of money to spend on sports lessons, so we come here. There are 30 of us in the club and we do cycling, running, gymnastics and some ball games. We work very hard, but we can’t practise very often. We don’t have courts or a swimming pool and all our equipment is very old. We usually practise in a big room in a school near here or in the park. The school doesn’t ask for money. Our club is very popular. And we are getting bigger and better! But we have a problem. Can you help us? We need more equipment – bikes, bats, balls, nets and rackets. We need money to pay for time in the swimming pool or on the tennis courts or at the sports centre. And we need money to travel to competitions. We need more trainers, too. John organises the club and Jane and Fisher do the training, but they need help.We know we can be winners. Please help us! Can you give us some money or equipment? You don’t have to give much. Or you can give us some of your time. You can be a trainer or come and help. Contact us at littleolympicclub.com and help the athletes of the future.1 All the members of the club are competition winners. T/F/NM2 It is expensive to join the club.
