Question

14．Sunshine might be healthier than most people think，outweighing the risk of skin cancer．British doctors suggested last week and ran straight into a storm．The four researchers at Bristol University in western England were accused of weakening years of campaigning to warn people of the dangers of too much sun．Experts agree exposure to the sun's ultraviolet rays （紫外线） increases the risk of skin cancer and accelerates the signs of aging．But in the British Medical Journal，the Bristol team led by Andrew Ness wrote，"There is evidence that the potential benefits of exposure to sunlight may outweigh the widely publicized negative effects on the incidence of skin cancer．"
Vitamin D，made in the body in reaction to sunlight，prevented rickets （软骨病） in children and was associated with a protective effect against heart disease．
Sunshine was also useful for treating certain skin conditions and there was evidence that it reduced the incidence of multiple sclerosis （硬化症）．There was also the"feel good effect of lying or sitting in the sun．"The researchers said it was too early to advise people to spend more time in the sun，but suggested the basis of the current advice to cover up should be reviewed．
"Perhaps，while we await the conclusions of such formal analyses，those of us who enjoy spending time in the sun can rest assured that the chance that we will be one of the people dying from the sun is small．"they added．
Their article was strongly criticized by health campaigners who claimed it was unbalanced and not backed by scientific evidence．Britain's Health Education Authority said skin cancer was the most common form of cancer in the country，with more than 50，000new cases diagnosed each year and more than 2，000people dying from the disease．It said treatment almost always required surgery and almost 50per cent of cases were fatal．The authority's skin cancer campaign manager Christopher New said，"We are very disappointed with this controversial article．It doesn't have enough supporting evidence and runs the risk of undoing many years of good health education．"

78．According to the four researchers at Bristol University，exposure to sunshine． does more good than harm．
79．What does the author mean by saying"the British doctors ran straight into a storm"？their statement caused much criticism from the health campaigners/they were strongly criticized by authorities/their article aroused a heated debate．
80．The"good health education"reminds peoplethat sunshine may cause skin cancer/of the risk of being exposed to sunshine．．
81．People have not yet been able to reach an agreement onwhether sunshine is good for people or not．．

Answer 1

分析 本文属于说明文阅读，作者通过这篇文章向我们说明了有新的证据表明暴露于阳光下的潜在收益可能大于如今所广泛宣传的关于可能患皮肤癌的概率，但是这种说法并没有得到肯定，因此人们现在还没有对阳光是否对人有好处达成协议．

解答 78．exposure to sunshine．    细节理解题，根据第一段The four researchers at Bristol University in western England were accused of weakening years of campaigning to warn people of the dangers of too much sun．Experts agree exposure to the sun's ultraviolet rays （紫外线） increases the risk of skin cancer and accelerates the signs of aging．可知布里斯托尔大学的四名研究人员说暴露在阳光下弊大于利，故填exposure to sunshine．
79．their statement caused much criticism from the health campaigners/they were strongly criticized by authorities/their article aroused a heated debate． 推理判断题，根据第一段   Sunshine might be healthier than most people think，outweighing the risk of skin cancer．British doctors suggested last week and ran straight into a storm．可推知"the British doctors ran straight into a storm"指的是这些英国医生的声明引起了许多来自健康运动者的批评，故填their statement caused much criticism from the health campaigners/they were strongly criticized by authorities/their article aroused a heated debate．
80．that sunshine may cause skin cancer/of the risk of being exposed to sunshine．    细节理解题，根据最后一段Their article was strongly criticized by health campaigners who claimed it was unbalanced and not backed by scientific evidence．Britain's Health Education Authority said skin cancer was the most common form of cancer in the country，with more than 50，000new cases diagnosed each year and more than 2，000people dying from the disease．可知良好的健康教育提醒人们暴露在阳光下可能会导致皮肤癌，故填that sunshine may cause skin cancer/of the risk of being exposed to sunshine．
81．whether sunshine is good for people or not．    推理判断题，根据最后一段"We are very disappointed with this controversial article．It doesn't have enough supporting evidence and runs the risk of undoing many years of good health education．"可知没有足够的证据支持暴露在阳光下利大于弊，因此人们还没有对阳光是否对人有好处达成协议，故填whether sunshine is good for people or not．
