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(生物學(xué)機制) 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。瑆hich 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.

32.B 推理判斷題.根據(jù)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.可知研究人們發(fā)現(xiàn)酒也可能成為人們飲食的一部分,適當(dāng)?shù)娘嬀撇⒉粫䦟?dǎo)致人們發(fā)胖.全文都在敘述與之有關(guān)的研究那么本文應(yīng)該是寫給那些喝酒的人的.故選B.
33.B 推理判斷題.根據(jù)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盡管酗酒的確可以增加體重,但那些適當(dāng)飲酒的人會減肥.根據(jù)連詞while可知,上下文存在對比關(guān)系.故選B.
34.C 推理判斷題.根據(jù)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,適量飲酒對于糖尿病有保護作用,即:適量飲酒的人不會患上糖尿。蔬xC.
35.C 推理判斷題.根據(jù)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,一項研究說明葡萄和紅酒中存在resveratrol,實際上可以破壞肥胖細胞,那么接下來就應(yīng)該是證明這一理論的正確性.故選C.
