Question

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes  in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.

試題分析：文章大意：槽糕的口腔衛(wèi)生差導(dǎo)致的社會和情感問題，作者想引起人們對于口腔問題注意并及時采取措施解決它。
小題1:C 細(xì)節(jié)理解題。根據(jù)第二段第一、第二句“Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London.”可知其人是與該機(jī)構(gòu)一起工作，并非該機(jī)構(gòu)的領(lǐng)導(dǎo)者，第二句提到他領(lǐng)導(dǎo)一個研究隊，所以A不對；B項提到“cure all major disease”太過絕對且文中并無體現(xiàn)；C項根據(jù)第二段第二、第三、第四句可知是正確的；D項提到第四段第一句是說他們一樣危險。故不對。
小題2:D 細(xì)節(jié)理解題。A項根據(jù)第三段第一、第二句可知對象誤用，排除；B項第三段第一句以及第六段第一句可知是錯的；C項提到成為發(fā)達(dá)國家是錯的，應(yīng)該為“more like western nations”才對；D項從第八段最后一句可以看出：這種疾病將引起心理混亂影響人們的交流。故D正確。
小題3:A 推理判斷題。作者寫本文就是引起人們關(guān)注這種疾病并采取措施處理。故A正確；B項告訴研究結(jié)果是片面的觀點；C項從第五段看出只是一個觀點；D項不是僅僅告訴醫(yī)生所以不對。
小題4:B 事實細(xì)節(jié)題。從文章結(jié)構(gòu)來看，先提出問題然后提出解決辦法，說明作者是持著關(guān)心的態(tài)度來寫的。故B正確。
考點: 健康保健類短文閱讀。
