Reading Comprehension (Reading in Depth) There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice. One of the most controversial issues in the vast literature about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do. But a new paper in the journal Clinical Research on Alcohol suggests that abstaining ( 戒除 ) from alcohol does tend to increase one's risk of dying, even when you exclude former problem drinkers. Abstainers' ( 戒酒者 ) mortality rates are higher than those of heavy drinkers. Moderate drinking, is associated with the lowest mortality rates in alcohol studies. Moderate alcohol use (especially when the choice is red wine) is thought to improve heart health, circulation and social ability, which can be important because people who are isolated don't have family members and friends who can notice and help treat health problems. It's true that those who abstain from alcohol tend to be from lower classes, since drinking can be expensive. And people of lower social and economic status have more life stress — job and child-care worries that might not only keep them from the bottle but also cause stress-related illnesses over long periods. But even after controlling for nearly all imaginable variables — social and economic status, level of physical activity, number of close friends, quality of social support and so on — the researchers led by Charles Holahan of the University of Texas found that over a 20-year period, mortality rates were highest for those who were not current drinkers, regardless of whether they used to drink, second highest for heavy drinkers and lowest for moderate drinkers. The sample of those who were studied included individuals between ages 55 and 65. The 1,824 participants were followed for 20 years. One drawback of the sample: a not appropriate number, 63 percent, were men. Even though heavy drinking is associated with higher risk for liver diseases and several types of cancer, heavy drinkers are less likely to die than those who don't drink, even if they never had a problem with alcohol. One important reason is that alcohol lubricates so many social interactions, which are vital for maintaining mental and physical health. As I pointed out last year, non-drinkers show greater signs of depression than those who allow themselves to join the party. The authors of the new paper are careful to note that even if drinking is associated with longer life, it can be dangerous: it can impair your memory severely and it can lead to non-fatal falls and other accidents (like, say, cheating on your spouse in a drunken mist) that can screw up your life. There's also the dependence: if you become addicted to alcohol, you may spend a long time trying to get off the bottle. 6 ) Why is drinking important for those isolated people?
A. Because drinking will make them feel no loneliness. B. Because drinking will make them free from social responsibilities. C. Because drinking will help them live a more social life. D. Because drinking will help them get back their families and friends.
