【正确答案】
A
【答案解析】[听力原文] The Mediterranean diet is based upon the eating patterns of traditional cultures in the Mediterranean region. Several noted nutritionists and research projects have concluded that this diet is one of the most healthful in the world in terms of preventing such illnesses as heart disease and cancer, and increasing life expectancy. The countries that have inspired the Mediterranean diet all surround the Mediterranean Sea. These cultures have eating habits that developed over thousands of years. In Europe, parts of Italy, Greece, Portugal, Spain, and southern France adhere to principles of the Mediterranean diet, as do Morocco and Tunisia in North Africa. Parts of the Balkan region and Turkey follow the diet, as well as Middle Eastern countries like Lebanon and Syria. The Mediterranean region is warm and sunny, and produces large supplies of fresh fruits and vegetables almost year round that people eat many times a day. Wine, bread, olive oil, and nuts are other staples of the region, and the Mediterranean Sea has historically yielded abundant quantities of fish. International interest in the therapeutic qualities of the Mediterranean diet began back in the late 1950s, when medical researchers started to link the occurrence of heart disease with diet. Dr. Ancel Keys performed an epidemiological analysis of diets around the world. Entitled 'the Seven Countries Study', it is considered one of the greatest studies of its kind ever performed. In it, Keys gathered data on heart disease and its potential causes from nearly 13,000 men in Greece, Italy, Croatia, Serbia, Japan, Finland, the Netherlands, and the United States. The study was conducted over a period of decades. It concluded that the Mediterranean people in the study enjoyed some significant health advantages. The Mediterranean groups had lower mortality rates in all age brackets and from all causes, particularly from heart disease. The study also showed that the Mediterranean diet is as high or higher in fat than other diets, obtaining up to 40% of all its calories from fat. It has, however, different patterns of fat intake. Mediterranean cooking uses smaller amounts of saturated fat and higher amounts of unsaturated fat, mostly in the form of olive oil. Saturated fats are fats that are found principally in meat and dairy products, although some nuts and vegetable oils also contain them. Saturated fats are used by the body to make cholesterol, and high levels of cholesterol have since been directly related to heart disease. Q: What has research concluded about the Mediterranean diet? 解题思路: 1.四项都以it开头,三项是现在时,一项是过去时。听音时要注意it的指代对象。 2.三项跟饮食有关(healthy diets, dairy products, seafood)。 本题问有关地中海饮食的研究得出的结论。讲话者在开头部分提到,一些著名的营养学家和研究项目得出结论:地中海饮食是世界上最为健康的饮食之一,可以预防心脏病和癌症等疾病,并延长人们的寿命。选项A的说法与此一致,故为正确答案。其余三项文中并未提及,故排除。
【正确答案】
C
【答案解析】[听力原文] Q: What do we learn about 'the Seven Countries Study'? 解题思路: 1.四项都是以it开头的陈述句,推断本题考查一种结论或客观事实。 2.由各项关键词researchers, conducted, greatest researches, attention of medical doctors可推断本题考查的内容可能与某项研究有关。 本题就“七国研究”进行提问。讲话者提到:“这项研究被称为‘七国研究’,被认为是有史以来同类研究中最伟大的研究之一。”选项C的说法与此一致,故为正确答案。讲话者提到:“基斯博士从来自希腊、意大利、克罗地亚、塞尔维亚、日本、芬兰、荷兰和美国的近1.3万个人身上收集了有关心脏病及其潜在病因的数据。”即讲话者是说从近1.3万个人身上收集数据,而选项A说1.3万名研究人员,描述错误。选项B中的Mid-Eastern countries和in the 1950s是根据讲话细节信息设置的干扰项,因与讲话内容不符,故可排除。讲话者并未提及选项D的内容,可排除。
【正确答案】
D
【答案解析】[听力原文] Q: What do we learn about the Mediterranean people from 'the Seven Countries Study'? 解题思路:四个选项都以they开头,都是现在时,并说明了四种不同的客观事实。听录音时,需要确认they的指代对象。 本题问“七国研究”得出了有关地中海地区的人们的什么结论。讲话者提到,“七国研究”得出结论:地中海地区的人有一些明显的健康优势。讲话者接下来提到,地中海沿岸地区的人群在所有年龄段和所有死因,特别是心脏病方面的死亡率更低。选项D的说法与此一致,故为正确答案。讲话者并未提及选项A的内容,可排除。讲话者提到,该研究还表明,地中海饮食的脂肪含量等同或者高于其他饮食,因此选项B错我。讲话者还提到,地中海烹饪使用较少的饱和脂肪和更多的不饱和脂肪,而不饱和脂肪主要是从橄榄油中获取。由此可知,地中海地区的人们烹饪时使用的(橄榄)油更多,故选项C错误。
