Sports shoes that work out whether their owner has done enough exercise to ensure time in front of the television have been invented in the prefix = st1 /UK.  The shoes--dubbed Square Eyes - contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day's efforts.   The design was inspired by a desire to combat the rapidly ballooning waistlines among British teenagers, said Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London. " We looked at current issues and childhood obesity really stood out," she told New Scientist. "And I wanted to tackle that with my design.   Once a child has used up their daily  _ gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.   Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time. The best title for the passage might be  _  . A) New Shoes and watching TV in the UK. B) A newly-invented type of shoes in the UK. C) Smart shoes deciding on television time. D) The problem of children's obesity.

If your preschoolers turn up their noses at carrots or celery, a small reward like a sticker for taking even a taste may help get them to eat previously disliked foods, a UK study said. Though it might seem obvious that a reward could encourage young children to eat their vegetables, the idea is actually controversial, researchers wrote in the American Journal of Clinical Nutrition. That's because some studies have shown that rewards can _ and cause children to lose interest in foods they already liked, said Jane Wardle, a researcher at University College London who worked on the study. Verbal praise, such as "Brilliant! You're a great vegetable taster," did not work as well. The study found t hat when parents gave their small children a sticker each time they took a "tiny taste" of a disliked vegetable, it gradually changed their attitudes. The children were also willing to eat more of the vegetables-either carrots, celery, cucumber, red pepper, cabbage or sugar snap peas-in laboratory taste tests, the study said. Researchers randomly assigned 173 families to one of these groups. In one, parents used stickers to reward their children each time they took a tiny sample of a disliked vegetable. A second group of parents used verbal praise. The third group, where parents used no special vegetable-promoting methods, served as a "control". Parents in the reward groups offered their children a taste of the "target" vegetable every day of 12 days, Soon after, children in the sticker group were giving higher ratings to the vegetables-and were willing to eat more in the research lab, going from an average of 5 grams at the start to about 10 grams after the 12-day experience. The turnaround also seemed to last, with preschoolers in the sticker group still willing to eat more of the once disliked vegetable three months later. Why didn't the verbal praise work? Wardle said the parents' words may have seemed "insincere" to their children. According to the passage, which of the following statements is true? A) Most children are born to dislike carrots or celery. B) It remains a question whether rewarding is a good way to get children to eat vegetables. C) Oral praise wokrs quite well in encouraging children to eat vegetables. D) Children in the sticker group will never lose interest in eating vegetables.

One day, my friend Jimmy told me a story. Farmer Joe was in his cart when he was hit by a truck. He decided his injuries from the accident were serious enough to take the trucking company (which caused the accident)to court. In court the trucking company's lawyer was questioning Farmer Joe. "Didn't you say, at the same scene of the accident, 'I'm fine'?" said the lawyer. Farmer Joe responded, "Well, I will tell you what happened. I had just loaded my favorite mule Bessie into the..." "I didn't ask for any details," the lawyer interrupted, "Just answer the question.Did you not say, at the scene of the accident, 'I'm fine? ' " Farmer Joe said, "Well, I had just got Bessie into the cart and I was driving down the road..." The lawyer interrupted again and said, "Judge, I am trying to make clear the fact that, at the scene of the accident, this man told the police on the scene that he was just fine. Now several weeks after the accident he is trying to cover the fact. I believe he is telling lies. Please tell him to simply answer the question." By this time the Judge was fairly interested in Farmer Joe's answer and said to the lawyer, "I'd like to hear what he has to say about his favorite mule Bessie." Joe thanked the Judge and went on, "Well, as I was saying, I had just loaded Bessie, my favorite mule, into the cart and was driving her down the road when this huge truck ran into the stop sign and pushed my cart right in the side. I was thrown into one side and Bessie was thrown into the other." "I was hurt so badly that I didn't want to move. However, I could hear old Bessie breathing loudly and groaning  . I knew she was in great pain. Shortly after the accident a traffic policeman came to the scene. He could hear Bessie groaning so he went over to her. After he looked at her, he took out his gun and shot her between the eyes. Then the patrolman came across the road with his gun and looked at me. He said, "Your mule was in such pain that I had to shoot her. How are you feeling?" Farmer Joe  _  . A) did say "I'm fine." at the scene of the accident B) couldn't have said "I'm fine." at the scene of the accident C) could not remember whether he had said "I'm fine." at the scene of the accident D) tried to cover the fact in the court but no one would believe him
