Article: Compared to high heels , they don't look dangerous, but flip-flop wearers should think twice before slipping on a pair. The National Health Service spends PS40 million a year treating injuries caused by wearing the casual footwear. More than 200,000 people end up in hospital every year after suffering falls or developing long-term problems. Once worn only at the beach, flip-flops have become the regular summer footwear of choice for women, with two in five women owning at least one pair. But experts are warning the public of the dangers of wearing flip-flops, such as the risk of joint pains. They say flip-flops force people to change the way they walk so that when taking a walk with long steps they put pressure on the outside of their foot, rather than their heel, causing long-term damage. And there is also the risk of serious injury. Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground. Many also suffer aching toes as they constantly wear them. Mike, a spokesman, warned wearers of the damage done by flip-flops. He said, "They land on the outside and then roll the foot inwards putting all the pressure on the big toe." This constant rolling puts pressure on the ankle joint, causing it to weaken. The lack of support of the flip-flop also causes pain on the inside of the foot and lower leg. And if you're not used to wearing them, they can cause blisters , he added. Doctors say flip-flops cause far more damage as they are worn for longer periods of time. Emma Supple, consultant podiatrist , said, "Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that wearing on hard flat surfaces can cause considerable foot and leg problems." She encouraged women to wear suitable shoes to help recover from summertime injuries.

Article: A couple who held hands at breakfast every morning even after 70 years of marriage have died 15 hours apart. Helen Felumlee, died at 92 on April 12. Her husband, 91-year-old Kenneth Felumlee, died the next morning. The couple's eight children say the two had been inseparable since meeting as teenagers, once sharing the bottom of a bunk bed on a ferry rather than sleeping on night apart. They remained deeply in love until the very end, even eating breakfast together while holding hands, said their daughter, Linda Cody. "We knew when one went, the other was going to go," she said. According to Cody, about 12 hours after Helen died, Kenneth looked at his children and said, "Mon's dead." He quickly began to fade, surrounded by 24 of his closest family members and friends when he died the next morning. "He was ready," Cody said, "He just didn't want to leave her here by herself." Son Dick said his parents died of old age, surrounded by family. The pair had known each other for several years when they eloped in Newport across the Ohio River from Cincinnati, on Feb. 20, 1994. At two days shy of his 21stbirthday, Kenneth-who went by Kenny-was too young to marry in Ohio. "He couldn't wait.' son Jim said. Kenneth worked as a railroad car inspector and mechanic before becoming a mail carrier for the Post Office. He was active in the church as a Sunday teacher. Helen stayed at home, not only cooking and cleaning for her own family but also for other families in need in the area. She taught Sunday school, too, but was known more for her greeting card ministry, sending cards for birthdays, sympathy and the holidays to everyone in her community, each with a personal note inside. "She kept Hallmark in business," daughter-in-law Debbie joked. When Kenneth retired in 1983 and the children began to leave the house, the Felumlees began to explore their love of travel, visiting almost all 50 states by bus. "He didn't want to fly anywhere because you couldn't see anything as you were going," Jim said. Although both experienced declining health in recent years, Cody said, each tried to stay strong for the other. "That's what kept them going," she said.
Question: From what Cody said, we can learn the children _ .
Options: (A) were not in front of their father (B) don't look after their father (C) foresaw their father would go (D) surrounded their father
answer:
C

Article: Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK. The shoes- named 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 fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design." Once a child has used up their daily allowance 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 exactly one minute of TV time. Existing pedometers normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations."
Question: According to Swan, the purpose of her design project is to _ .
Options: (A) keep a record of the steps of the wearer. (B) deal with overweight among teenagers. (C) enable children to resist the attraction of TV. (D) prevent children from being tricked by TV programs.
answer:
B
