2．It has always been thought that alcohol causes people to put on weight because it contains a lot of sugar，but new research suggests a glass a day cold 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 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．

解答 32--35 BBCC
32．B 推理判断题．根据文章第一段第一句It has always been thought that alcohol causes people to put on weight because it contains a lot of sugar，but new research suggests a glass a day cold form part of a diet．可知研究人们发现酒也可能成为人们饮食的一部分，适当的饮酒并不会导致人们发胖．全文都在叙述与之有关的研究那么本文应该是写给那些喝酒的人的．故选B．
33．B 推理判断题．根据文章第一段第二句Looking at past studies they found that，while heavy drinkers do put on weight； those who drink in moderation can actually lose weight尽管酗酒的确可以增加体重，但那些适当饮酒的人会减肥．根据连词while可知，上下文存在对比关系．故选B．
34．C 推理判断题．根据文章第三段第二句His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes，which relate to increasing obesity可知，适量饮酒对于糖尿病有保护作用，即：适量饮酒的人不会患上糖尿病．故选C．
35．C 推理判断题．根据文章最后一段What's more，a study three years ago suggested that resveratrol，a compound present in grapes and red wine destroys fat cells可知，一项研究说明葡萄和红酒中存在resveratrol，实际上可以破坏肥胖细胞，那么接下来就应该是证明这一理论的正确性．故选C．
