“Don't Drink Alone” Gets New MeaningIn 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 and neck than do those taking their libations with food. Luigino Dal Maso and his colleagues studied the drinking patterns of 1,500 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 meals3 faced at least a 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 狂 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 a week at least doubled their cancer risk for all sites other than the larynx10. If people in these consumption groups took 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 cancer 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 triple 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.
詞匯：
cavity n.腔
pharynx n.咽
pharyngeal adj.咽的
esophagus n.食管
esophageal adj.食管的
larynx n.喉
scrub v.擦凈，擦掉
注釋：
1. …than do those taking their libations with food：這是一個倒裝句，其正常語序為 than those taking their libations with food do。這里的do是一個代詞，代替上半句中的have a significantly higher risk of cancer in the mouth and neck。
2. drinking patterns of 1,500 patients from four cancer studies ：取自四項癌癥研究的 1，500 個病例的飲酒習(xí)慣模式
3. downed a significant share of their alcohol outside of meals：在就餐時間以外灌下大量烈酒。 down：在此作動詞用，意為：“喝下，灌下”；significant：意為“large in amount”（大量的）。
4. laryngeal：larynx （喉）的形容詞形式。
5. these four sites：指該段前兩句提到的 oral cavity，pharynx, esophagus, larynx。
6. traced to smoking or drinking：根源就是抽煙或喝酒。trace to:回溯到……
7. in an average week：平均每星期
8. up to：高達
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意為“（食物或飲料的）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）高攝入、僅在就餐時飲酒的（實驗）組。 high-intake和with-meals-only在此都是合成形容詞，修飾group。
12. was only triple that：是它的三倍。that 指該句前半句中的 laryngeal cancer risk。
練習(xí)：
1. Researchers have found that the risk of cancer in the mouth and neck is higher with people
A who drink alcohol outside of mealsur
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 8 drinks. 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.
答案與題解：
1. A文章第一個句子就是答案。
2. C第二段的第二句說的是餐外飲酒使得喉癌幾率增加了20%，而不是就餐飲酒的情況。所以C是正確答案。其他三項均在文中直接或間接提到。
3. A第三段第二句告訴我們，酒精攝人量最低的一組每星期飲酒量達20杯，因此，大約每天在三杯左右。
4. B文章第四段的第一句和第二句是由連接詞in contrast連接的兩個句子。in contrast表達的是句間的反比關(guān)系。第一句說明酒精消費量最大的一組，患其他三種癌癥的幾率與低酒精攝入量組相比，分別是他們的10倍、7倍和16倍，而第二句告訴我們，相比之下，其患喉癌的機率只是另一組的3倍。因此，B是正確選項。
5. D文章最后一句提供了答案。
