1、XX职称英语理工类A级阅读理解练习试题 In what may be bad news for bars and pubs, an European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those taking their libations with food. Luigino Dal Maso and his colleagues studi
2、ed the drinking patterns of 1,500 patients from four cancer studies and another 3,500 adults who had never had cancer. 一定程度上，这对酒吧可能是一个坏消息，欧洲的一个研究小组发现人们在就餐时间以外饮酒会使患口腔和颈部癌症的机率比就餐时饮酒更高。Luigino Dal Maso和他的同事们研究了取自四项癌症研究的1,500个病例的饮酒习惯模式和另外3,500个从没患癌症的成年人的饮酒习惯模式。 After the researchers aounted for the amou
3、nt of alcohol consumed, they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity, pharynx, and esophagus, when pared with people who drank only at meals. Consuming alcohol without food also increa
4、sed by at least 20 percent the likelihood of laryngeal cancer. “Roughly 95 percent of cancers at these four sites traced too smoking or drinking by study volunteers,” Dal Maso says. The discouraging news his team reports, is that drinking with meals didnt eliminate cancer risk at any of the sites. 在
5、研究者分析了饮酒的总量后，他们发现和只在就餐时饮酒的人相比，在就餐时间以外灌下大量烈酒的人面临至少50%80%的患口腔癌、咽癌和食道癌的危险。在就餐时间外饮酒也会使患喉癌的可能性增加至少20%。“被研究者的情况说明大约95%患以上四种癌症的原因就是抽烟或饮酒。”Dal Maso说。他的研究小组提供的报告令人沮丧的消息是就餐时饮酒不会消除患以上任何一种癌症的危险。 For their new analysis, the European scientists divided people in the study into four groups, based on how many drink
6、s they reported having in an average week. The lowest-intake group included people who averaged up to 20 drinks a week. The highest group reported downing at least 56 servings of alcohol weekly for an average of eight or more per day. Cancer risks for the mouth and neck sites rose steadily with cons
7、umption even for people who reported drinking only with meals. For instance, pared with people in the lowest-consumption group, participants who drank 21 to 34 alcohol servings a week at least doubled their cancer risk for all sites other than the larynx. If people in these consumption groups took s
8、ome of those drinks outside meals, those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers. 为了进展新的分析，欧洲科学家根据每星期平均饮酒量将被研究者分为4组。饮酒量最少的一组包括每周平均饮酒量达20杯的人，饮酒量最高的一组每周饮酒至少56杯，平均每天8杯以上。患口腔癌和喉癌的危险随着饮酒量而稳定上升，即使是那些只在就餐时饮酒的人。例如，和低饮酒量的人相比，每周饮酒2134杯的人患除喉癌以外其他部位的
9、癌症的危险增加了一倍。如果这几组中的人在就餐时间以外饮酒，那些属于高饮酒量组的人会使他们患口腔癌和食道癌的危险至少增加3倍。 People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer, 7 times the risk of pharyngeal cancer, and 16 times the risk of esophageal cancer pared with those who averaged 20 or fewer drinks a
10、week with meals. In contrast, laryngeal cancer risk the high-intake, with-meals-only group was only triple that in the low-intake consumers who drank with meals. 和每周只在就餐时平均饮酒至多20杯的人相比，高饮酒量组的人在就餐时间饮酒患口腔癌的危险是低饮酒量组的10倍，咽癌是其7倍，食道癌16倍。相反，酒精高摄入且仅在就餐时饮酒的人患喉癌的危险是酒精低摄入且仅在就餐时饮酒的人的3倍。 “Alcohol can inflame tiss
11、ues. Over time, that inflammation can trigger cancer.” Dal Maso says. He suspects that food reduced cancer risk either by partially coating digestive-tract tissues or by scrubbing alcohol off those tissues. He speculates that the reason laryngeal risks were dramatically lower for all study participa
12、nts traces to the tissues lower exposure to alcohol. “酒精能使组织发炎，一段时间后，炎症可引发癌症。”Dal Maso说。他认为食物降低了患癌症的危险，或是通过覆盖在消化道组织上或是通过将酒精从那些组织上擦除。他推测所有被研究者患喉癌的机率比其他癌症低很多的原因是组织被酒精侵害到的局部少。 1.
