Health officials issued a waring over common energy-saving lghtbulbs after research showed some types could potentially harm the skin and may even raise the risk of cancer. A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics. John O'Hagan, a scientist at the HPA's centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light. The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were _ to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn. The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs. In order not to be harmed by the UV radiation from some lightbulbs, people should _ . A) stop using eco-friendly lightbulbs at home B) avoid using open lightbulbs for long close work C) take care not to expose their skin to direct sunlight D) urge the government to ban the use of lightbulbs

The health and welfare of every person in America will be affected by global warming, especially children, the elderly and the poor, according to a new White House science report. The report said every region of the country will suffer worse health from heat waves and drought. _ It predicts an increase in diseases spread by tainted food, bad water and bugs . The report concludes that climate change causes real risk to human health and human system that supports the way of life in the United States. Man-made global warming is caused by greenhouse gases from the burning of fossil fuels. At current emission levels, global temperatures are likely to rise by about 2 degrees by midcentury and about 7.5 degrees by the end of the century. The most vulnerable Americans -- the poor, elderly, sick, very young and immigrants -- will suffer more. That's at least 10 percent of the country's population, probably more. It will be tougher for these people to get enough health care for climate-related illnesses, to cool down in heat waves, to escape extreme events such as Hurricane Katrina, and even to get enough food. While every region of America is vulnerable to global warming's health and welfare effects, more people are moving to coastal regions, which are most vulnerable to climate change because of drought and hurricanes. The writer wrote this passage to _ . A) explain how the phenomenon of global warming forms B) protect the vulnerable Americans from suffering from diseases C) provide evidence that global warming and climate change risk human's health D) warn every American of the danger of global warming to their health

Q: "Can I see my baby?" the happy new mother asked. When the bundle was in her arms and she moved the fold of cloth to look upon his tiny face, she gasped. The doctor turned quickly and looked out of the tall hospital window. The baby had been born without ears. Time proved that the baby' s hearing was perfect. It was only his appearance that was imperfect. When he rushed home from school one day and threw himself into his mother's arms, she sighed , knowing that his life was to be unfortunate. He cried to his mum "A boy, a big boy... called me a freak ." He grew up, handsome. A favorite with his fellow students, he might have been class president, but for that. He developed a gift, a talent for literature and music. "But you might communicate with other young people," his mother blamed him, but felt a kindness in her heart. Two years went by. One day, his father said to the son, "You' re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it' s a secret." The operation was a great success, and a new person appeared. Later he married and became a lawyer. One day, he asked his father, "Who gave me the ears? Who gave me so much? I could never do enough for him or her." "I do not believe you could," said the father, "but the agreement was that you are not to know... not yet." The years kept their secret, but the day did come.

(Question)
I decided to have dinner in the hotel, for I arrived late one night on a business trip. As I was finishing my meal, an elderly couple came in to dine. They were holding hands and had lovely smiles on their faces. They sat three tables from me. I was amazed at the love they showed for each other. It seemed to strike home all the more, because it was shortly after ending a 20-year marriage and I still had pain in my heart. My waiter was also their waiter. As I paid my bill, I inquired as to what their bill was. He informed me, and I gave him $40 to pay their bill. He asked if I knew them and I told him "No, I just wanted to repay them for the love that they were showing to each other," and then I departed. The next day I entered the restaurant to dine before my departure. After I had been seated, the waiter who served me the night before told me that the strangest thing happened after I left the restaurant. When the elderly couple went to pay for their meal, they were informed that it had been paid. When they inquired who had done this, the hostess told them they had no idea who I was, just retelling what I said. The couple were amazed. They looked around, asked for the bill of two young couples who were seated together, paid their bill and departed, saying "Love begets Love" to the amazement of the hostess and waiter. I smiled and said "That's nice," and proceeded to order my meal. About 45 minutes later, I finished my meal and was about to head out, but my waiter was nowhere to be found. I waited and waited and finally walked over to the hostess stand and explained that I needed to pay for my meal and hurry to the airport. She smiled and explained that I would not have to pay for my meal, because both the waiter and she felt compelled to pay my bill due to the joy that was brought to the faces of the elderly couple and the amazement of the young couples. When I told her that they didn't have to do that, she said with a smile "Love begets Love." What can be inferred from the story? A) The love between the elderly couple deeply touched the writer who was single. B) The young couples paid the bill of other customers in the restaurant. C) The waiter left on purpose and made the writer stay alone to test him. D) The writer did all this to prove his belief in love.
