阅读理解 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 (感受器) and do not cause any technological or safety problems,” Dr He said.1.According to the passage, obesity is directly linked to ______.A.high-salt foodsB.sugar-sweetened soft drinksC.high blood pressureD.strokes and heart attacks2.Compared with previous studies, the recent one found that ______.A.a lower-salt diet may mean less sugar-sweetened soft drink consumptionB.a low-salt diet keeps children out of high blood pressureC.children face the risk of having strokes and heart attacksD.low-salt food products do not do harm to people’s health3.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.4.After reading the passage, who should take effective action?A.Children.B.Parents.C.Doctors.D.Researchers.

BADB解析1.从第二段中“It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people.”和第四段最后一句可知，喝含糖饮料会导致热量摄入而引发肥胖，因此B项正确。2.通过第四段可知，A项所述为新的研究发现。3.第五段直接说出低盐的食物可以预防高血压；结合以上几段可知低盐食物可以让孩子少喝含糖的饮料，而含糖的饮料会导致发胖，因此D项正确。4.根据最后一段中的第一句可知B项正确
