"Don't Drink Alone” Gets New Meaning
(考题预测班 第10讲)
In what may be bad news for bars and pubs, a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth arid neck than do those taking their libations with food. 1 Luigino Dal Maso and his colleagues studied the drinking patterns of l,500 patients from four cancer studies2 and another 3.500 adults who had never had cancer.
After the researchers accounted for the amount of alcohol consumed, they found that individuals who downed a significant share of their alcohol outside of meals3faced at least at 50 to 80 percent risk of cancer in the oral cavity, pharynx, and esophagus, when compared with people who drank only at meals. Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal4 cancer. "Roughly 95 percent of cancers at these four sites5 traced to smoking or drinking6 by the study volunteers." Dal Maso says. The discouraging news, his team reports, is that drinking with meals didn't eliminate cancer risk at any of the sites.
For their new analysis, the European scientists divided people in the study into four groups, based on how many drinks they reported having in an average week7. The lowest-intake group included people who averaged up to8 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.9 Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals. For instance, compared with people in the lowest-consumption group, participants who drank 21 to 34 alcohol servings week at least doubled their cancer risk for all sites other than the larynx.10 If people in these consumption groups Look some of those drinks outside meals, those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers.
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 cancers, compared with those who averaged 20 or fewer drinks a week with meals. In contrast, laryngeal cancer risk in the high-intake. With-meals-only group11 was only trip that12 in the low-intake consumers who drank with meals.
"Alcohol can inflame tissues. 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 participants traces to the tissue's lower exposure to alcohol.
词汇：
Cavity n腔 triple adj三倍的;n三倍;v成三倍
pharynx n咽 serving n(食物或饮料的)一份
pharyngeal adj 咽的 inflame v使发炎
esophagus n食管 digestive-tract tissue消化道组织
esophageal adj食管的 scrub v.撩净，擦掉
quadruple v成四倍;adj四倍的
larynx n喉 laryngeal adj喉的
注释：
1 than do those taking their libations with food:这是一个倒装句，其正常语序为than those taking their libations with food do。这里的do是一个代侧，代替上半句中的have a significantly higher risk of cancer in the mouth and neck。
2 drinking patterns of l,500 patients from four cancer studies:取自四项癌症研究的1,500个病例的饮酒习惯模式
3 downed a significant share of their alcohol outside of meals:在就餐时间以外灌下大量烈酒。down:在此作动词用，意为：“喝下，灌下”;significant:意为“large in amount”(大量的)。
4 laryngeal: larynx(喉)的形容词形式。
5 these four sites:指该段前两句提到的oral cavity, pharynx. esophagus, larynx。
6 traced to smoking or drinking:根源就是抽烟或喝酒。trace to:回溯到……
7 in an average week:平均每星期
8 up to:高达
9 56 servings of alcohol weekly for an average of eight or more per day:每周56杯，平均每天8杯以上。eight后省略了servings意为“(食物或饮料的)一份”。
10. for all sites other than the larynx:除喉以外的全部部位。other than:除了。
11. high-intake, with-meals-only group:(酒精)高摄人、仅在就餐时饮酒的(实验)组。 high-intake和with-meals-only在此都是合成形容词，修饰group。
12. was only triple that:是它的三倍。that指该句前半句中的laryngeal cancer risk。
练习：
l Researchers have found that the risk of cancer in the mouth and neck is higher with people
A who drink alcohol outside of meals
B who drink alcohol at meals
C who never drink alcohol
D who drink alcohol at bars and pubs
2 Which of the following is NOT the conclusion made by the researchers about “drinking with meals”?
A It has a lower risk of cancer than drinking without food
B It may also be a cause of cancer
C It increases by 20 percent the possibility of cancer in all sites
D It does not eliminate cancer risk at any of the sites
3 Approximately how many drinks do the lowest-intake group average per day ?
A 3 drinks B 8drinks C 20 drinks D 56 drinks
4 Which cancer risk is the lowest among all the four kinds of cancer mentioned in the passage ?
A Oral cancer B Laryngeal cancer
C Pharyngeal cancer D Esophageal cancer
5 According to the last paragraph. tissue's lower exposure to alcohol
A explains why inflammation triggers cancer
B accounts for why food can coat digestive-tract tissues
C is the reason why food can scrub alcohol off tissues
D reduces the risk of laryngeal cancer
答案与题解：
1 A文章第一个句子就是答案
2 C第二段的第二句说的是餐外饮酒使得喉癌几率增加了20%，而不是就餐饮酒的情况。所以C是正确答案。其他.：项均在文中直接或间接提到。
3 A第三段第二句告诉我们，酒精摄人量最低的一组每星期饮酒量达20杯，因此，大约每天在三杯左右。
4. B文章第四段的第一句和第二句是由连接词in contrast连接的两个句子。in contrast表达的是句间的反比关系。第一句说明酒精消费量最大的一组，患其他三种癌症的几率与低酒精摄入量组相比，分别是他们的10倍、7倍和16倍，而第二句告诉我们，相比之下，其患喉癌的机率只是另一组的3倍。斟此，B是正确选项。
5 D文章最后一句提供了答案。
