Question

A glass a day keeps obesity at bay．Alcohol has always been thought to cause weight gain because of its high sugar content，but new research suggests a glass a day could form part of a diet．Looking at past studies they found that，while heavy drinkers do put on weight，those who drink in moderation can actually lose weight．

A spokesman for the research team at Navarro University in Spain says，“Light to moderate alcohol intake，especially of wine，may be more likely to protect against，rather than promote，weight gain．”The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions，particularly that current data do not clearly indicate if moderate drinking increases weight．

Boston University’s Dr．Harvey Finkel found that the biologic mechanisms(生物学机制)relating alcohol to changes in body weight are not properly understood．His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病)，which relate to increasing obesity．Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers．

The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat，and that this process could explain the differences in its effects from those of other foods．They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks，taking into consideration drinking patterns and including the past tendency of participants to gain weight．

For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese．What’s more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine，destroys fat cells．

【解析】

试题分析：本文属于科普说明文，介绍了适量饮酒不仅不会让人发胖，反而会帮助人们减肥。

1.B 推理判断题。根据第一段A glass a day keeps obesity at bay.....those who drink in moderation can actually lose weight．可知每天喝一杯酒可以有效预防肥胖，这与之前的发现相反。使用本文是写给那些有饮酒习惯的人。与生产出售和想要戒酒的人无关。故B正确。

2.C 词义猜测题。本句while heavy drinkers do put on weight，those who drink in moderation can actually lose weight中的in moderation与heavy drinkers形成呼应，酗酒的会发胖，但是那些适量饮酒的人是可以减肥的。故C项正确。

3.D 推理判断题。根据第二段第一句.....“Light to moderate alcohol intake，especially of wine，may be more likely to protect against，rather than promote，weight gain．可知适当饮酒对我们的身体有较强的保护效果。故D项正确。

4.D 推理判断题。根据本文最后一句What’s more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine，destroys fat cells．可知三年前的一项研究发现适量饮用红酒可以破坏肥胖细胞。那么接下来的内容就应该对这一理论进行证明。故D项正确。
