Read the text and choose the best anwers to the following questions When I injured my back I had to take a break from my running career. I decided to introduce more women to the sport to show them how much fun it can be and to give them confidence to get out and run. I decided to start a running club for women in my area because I was annoyed by the attitude of many organizers. They complain about the lack of women in the sport but also use this as an excuse for not providing separate changing facilities. I put up poster and 40 women , young and old fit or unfit joined. All of these were attracted by the ideas of losing weight but I don't think they had really thought about running before. When or if they did, they had a picture of painful training. They didn't think of chatting and smiling while running in beautiful places, like by a tree. At first they ran for only a minute now they can run for thirty minutes. They've also learned from other runners about diet and keeping fit in general. I wanted to do something for women's running and I've had so much pleasure watching their progress- almost as much as they've had themselves. 1. What is the writer's main aim in writing the text? A. to describe her own running career B. to complain about race organizers C. to talk about women runners D. to describe good running method 2. what would a reader find out from the text? A. The best kinds of places for running B. How runner can avoid injuring themselves. D. The teaching skills of the writer C. the progress made by the women in the club.
