单选题A Source of Concern As millions of children head back to school, doctors are bracing for an increase in asthma (哮喘) attacks. The exposure to allergens (过敏物质) and contagious (接触传染的) colds and viruses in the classroom often triggers episodes among asthmatics, leading to a spike (突然上升) each fall in the number of hospitalizations for the disease. And there are plenty of children at risk: research published in this week' s issue of the British medical journal. The Lancet finds asthma has become more prevalent in younger children in North American over the past decade. If the chronic condition is controlled through medication and management plans, children call usually lead relatively normal, healthy lives. But many parents aren' t taking such steps. In a survey by the American Lung Association reported Tuesday, nearly three quarters (73 percent) of 2,010 parents with asthmatic children said they are concerned about how their child's asthma will affect their ability to participate in school. Yet fewer than a third of the parents have made sure their children are under medical supervision or have talked to school administrators about their child's asthma. And fewer than half (48 percent) say they've talked to the school teachers about their child's asthma or made sure the child's medicine is available at school (42 percent). "That' s a source of concern," says Dr. Norman H. Edelman, chief medical officer for the American Lung Association, which has launched a back - to--school campaign to help parents recognize asthmatic symptoms in their kids and to develop a management plan. "This really has to be a collaboration between the doctor, parents, child and school. " It is the most common chronic condition and the leading cause of hospitalizations for those under18, according to the Asthma and Allergy Foundation. Edehnan says as many as 2 million more may have mild forms of the disease that have not have been diagnosed. Frequent shortness of breath and wheezing are common symptoms of the chronic condition. Parents should also check with their child's physician if their child is waking up coughing during the night or can' t keep up with other children during playtime.

单选题{{B}}第二篇{{/B}} {{B}}Brain-dead Mother Dies after Giving Birth{{/B}} A brain-dead woman who was kept alive for three months so she could deliver the child she was carrying was removed from life support on Wednesday and died, a day after giving birth. "This is obviously a bittersweet time for our family," Justin Torres, the woman's brother-in-law, said in a statement. Susan Torres, a cancer-stricken, 26-year-old researcher at the National Institutes of Health, suffered a stroke in May after the melanoma (黑瘤) spread to her brain. Her family decided to keep her alive to give her foetus (胎儿) a chance. It became a race between the foetus' development and the cancer that was destroying the woman's body. Doctors said that Torres' health was getting worse and that the risk of harm to the foetus finally outweighed the benefits of extending the pregnancy. Torres gave birth to a daughter by Caesarean section (剖腹产手术) on Tuesday at Virginia Hospital Center. The baby was two months premature and weighed about a kilogram. She was in the newborn intensive care unit. Dr Donna Tilden-Archer, the hospital's director of neonatology (新生儿学), described the child as "very vigorous." She said the baby had responded when she received stimulation, indicating she was healthy, Doctors removed Torres from life support early Wednesday with the consent of her husband, Jason Torres, after she received the final sacrament (圣礼) of the Roman Catholic Church. "We thank all of those who prayed and provided support for Susan, the baby and our family," Jason Torres said in a statement. "We especially thank God for giving us little Susan. My wife's courage will never be forgotten." English-language medical literature contains at least 11 cases since 1979 of irreversibly brain-damaged women whose lives were prolonged for the benefit of the developing foetus, according to the University of Connecticut Health Center. Dr Christopher McManus, who coordinated care for Susan Torres, put the infant's chances of developing cancer at less than 25 per cent. He said 19 women who have had the same aggressive form of melanoma as Torres have given birth, and five of their babies became iii with the disease.

单选题Florida Hit by Cold Air Mass In January, 2003, the eastern two-thirds of the United States was at the mercy of a bitterly cold air mass that has endangered Florida"s citrus trees, choked northern harbors with ice and left bewildered residents of North Carolina"s Outer Bands digging out of up to a foot of snow. The ice chill deepened as temperatures fell to the single digits in most of the South, with an unfamiliar dip below the freezing mark as far south as parts of interior South Florida. Temperatures in Florida plunged, with West Palm Beach dropping to a record low of 2 degrees. "We couldn"t believe how cold it was," said Martin King, who arrived this week in Orlando from England. "We brought shorts, T-shirt, and I had to go out and buy another coat." The temperature plunge posed a threat to Florida"s USD-9.1-billion-a-year citrus crop, more of which is still on the trees. Growers were hurrying to harvest as much of the fruit as possible before it was damaged by cold. "Time is of the essence in getting fruit to the plant," said Tom Rogers, a citrus grower who expected to see damage to oranges and grapefruit at that time. In Florida, Governor Jeb Bush signed an emergency order to eliminate the weight limit on trucks so citrus growers could get as much fruit to market as possible. Casey Pace, a spokeswoman for Florida Citrus Mutual, said growers had sprayed trees with sprinklers, which created a layer of ice and helped maintain a temperature near freezing. Citrus trees are considered in danger of damage if the temperature drops below minus 2 degrees Celsius for four hours or more. Snow ranging from a dusting to up to 30 centimeters blanketed the Carolinas, Tennessee and parts of Virginia.

单选题Breast Cancer Deaths Record Low The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began. The Cancer Research UK data showed that 11,990 women died in the UK in 2007. The previous lowest figure had been recorded in 1971—the year records began after which it rose steadily year by year until the late 1980s. Professor Peter Johnson, Cancer Research UK's chief clinician said, "It's incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often." Research has played a crucial role in this progress leading to improved treatments and better management for women with the disease. "The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed." Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years. The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004. There was a slight rise in 2005 and then two years of falls. Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease." "However, this is still too many women and incidence of the disease is increasing year by year." The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity (肥胖) and alcohol consumption.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 {{B}} Hercules{{/B}} Once upon a time there was a great Greek hero, Hercules. He was taller and stronger than anyone you have ever seen. On his shoulder he carried a club and in his hand he held a bow (弓). He was known as the hero of a hundred adventures. Hercules served a king. The king was afraid of him. So again and again he sent him on difficult tasks. One morning the king sent for him and told him to fetch three golden apples for him from the garden of the Singing Maidens(歌女). But no one knew where the garden was. So Hercules went away. He walked the whole day and the next day and the next. He walked for months before he saw mountains far in the distance one fine morning. One of the mountains was in the shape of a man with long, long legs and arms and huge shoulders and a huge head. He was holding up the sky. Hercules knew it was Atlas, the Mountain God. So he asked him for help. Atlas answered, "My head and arms and shoulders all ache. Could you hold up the sky while I fetch the golden apples for you?" Hercules climbed the mountain and shouldered the sky. Soon the sky grew very heavy. When finally Atlas came back with three golden apples, he said, "Well, you are going to carry the mountain for ever. I'm going to see the king with the apples.' Hercules knew that he couldn't fight him because of the sky on his back. So he shouted: "Just one minute's help. My shoulders are hurting. Hold the sky for a minute while I make a cushion(垫子) for my shoulders." Atlas believed him. He threw down the apples and held up the sky. Hercules picked up the apples and ran back to see the king.
