                 In your  daily life, you  use a  lot of machines to  perform  different  activities.
                 For example, you use a sharpener to sharpen your pencil, a refrigerator to keep
                 your things cool and fresh, a television to watch your favourite cartoons, a fan to
                 keep ourselves cool.
