"Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity," researchers recently reported in the journal Hypertension. "Sugar-sweetened soft drinks are a significant source of calorie intake in children," said Feng J. He, a researcher at St George's University of London, England. "It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people." They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption. Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. "We found that children eating a lower-salt diet drank less fluid," said He. "From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day." The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. "If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week," Dr He said. In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. "Both high blood pressure and obesity increase the risk of having strokes and heart attacks," Dr He said. Dr He recommends that parents check labels and choose low-salt food products. "Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors   and do not cause any technological or safety problems," Dr He said. Which of the following statements would Dr He agree to? A) The less salt people eat, the healthier people become. B) Children should reduce fluid intake in their daily life. C) No high-salt food products will be available in shops. D) A low-salt diet may prevent both high blood pressure and obesity.

Q: Heritage is our legacy from the past, what we live with today, and what we pass on to future generations. Our cultural and natural heritage are both irreplaceable   sources of life and inspiration. Places as unique and diverse as the wilds of East Africa's Serengeti, the Pyramids of Egypt, the Great Barrier Reef in Australia and the Baroque cathedrals of Latin America make up our world's heritage.  What makes the concept of World Heritage exceptional is its universal application. World Heritage sites belong to all the peoples of the world, regardless of the territory on which they are located. The United Nations Educational, Scientific and Cultural Organization (UNESCO) seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity. This is _ in an international treaty called the Convention Concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972. UNESCO's World Heritage mission is to: encourage countries to sign the World Heritage Convention and to ensure the protection of their natural and cultural heritage;  encourage States Parties to the Convention to nominate  sites within their national territory for inclusion on the World Heritage List;  encourage States Parties to establish management plans and set up reporting systems on the state of conservation of their World Heritage sites; help States Parties safeguard World Heritage properties by providing technical assistance and professional training; provide emergency assistance for World Heritage sites in immediate danger; support States Parties' public awareness-building activities for World Heritage conservation; encourage participation of the local population in the preservation of their cultural and natural heritage; encourage international cooperation in the conservation of our world's cultural and natural heritage. Which of the following statements about heritage is NOT true? A) It is exceptional because of its universal application. B) It can be divided into two sorts: the cultural and the natural. C) It's the irreplaceable sources of life and inspiration. D) It has the characteristics of being unique and diverse.
A: A


(Question)
Water and its importance to human life are the center of the world's attention. March 22 is World Water Day, which has the theme "Water and culture "this year. There are more than one billion people in the world who live without safe drinking water. The United Nations hopes to cut this number in half by 2015. Solving such a big problem seems like an unreal challenge. But everyone, even teenagers, can do something to help. A teenage girl in the U.S. has set an example to others of her age around the world. Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work of collecting deserted batteries which pollute water. In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There, she saw an exhibit about how chemicals in old batteries harm the water of Lake Erie. Haggerty learnt that recycling the batteries was an easy solution. "I think everybody can do it, because everyone uses batteries, and it can make a big difference." With these words, she began to increase awareness in her area. She talked to her county government and school board. She got permission to start a recycling programmed in schools as well as the public libraries, hospitals, and churches. With the help from her family, friends and local waste-management officials, she gathered containers, arranged transportation, and made an educational video. Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programmed but had made little progress. When asked if she feels like a hero, Haggerty is quite modest . "Not really. Well, maybe for the fish I saved!" Every year the Gloria Barron Prize honors young Americans aged 8 to 18 who have shown leadership and courage in serving the public and the planet. Each year ten winners receive $2,000 each, to help with their education costs or their public service work. In order to collect used batteries, Rene Haggerty did the following things EXCEPT    _    . A) gather some containers B) arrange the transportation C) make an educational video D) go on a field trip
