1、练习双语：怎么才能管住自己的嘴远离垃圾食品肚子越来越大，臀部脂肪越来越厚，还是管不住自己的嘴，到底应该怎样才能远离垃圾食品呢？A new study confirms what you likely already know: Few things can stop us from huntingdown the foods we crave.一项新研究证实了一件你可能已经知道的事情：我们很难抵御诱惑，不去吃那些渴望的食物。A study published Monday in the journal Proceedings of the National Academy of Science
2、sfound that people are willing to overpay when theyre craving junk food underscoring just howpowerful these feelings are.美国科学院院报(Proceedings of the National Academy of Sciences)在本周一发表的研究报告中指出，那些渴望垃圾食品的人愿为它们付出更多钱，可见这种感受有多么强烈。In one experiment, 44 non-dieters who had not eaten for four hours were aske
3、d how muchthey wanted 15 different snack foods, as well as how much they would pay for each item out of a$5 budget. Next, each person went through a multi-sensory experience meant to prompt cravingsfor one of three desirable foods: a Snickers bar, Cheetos or a Coke. They were then asked howmuch they
4、 wanted that particular item, and how much they would pay for it.在一项实验中，44位非节食者在四个小时没有进食后，要回答他们对于15种不同快餐食品的渴望程度，以及如果有5美元的预算，他们愿意为每种食品付出多少钱。接着，每位受试者会接受多重感官的刺激，以激起他们对三种可口的食品：土力架(Snickers)能量条、奇多(Cheetos)膨化食品或可口可乐(Coke)之一的渴望。随后，他们要回答对这种特殊食品的渴望程度，以及愿意为它付出多少钱。Not only did desire increase, but the research
5、ers also found that participants were willing topay an average of $0.66 more for the item they had been made to want, and an average of $0.26more for similar snacks. When presented with less-similar (and, thus, healthier) items, such as agranola bar or pretzels, they were not willing to pay as much,
6、 suggesting that cravings operatedistinct from general hunger.研究人员发现，受试者对这种特定食品有了更强的渴望，还愿意为它平均额外付出066美元，或是为类似的快餐食品平均额外付出0.26美元。而对于那些相似度较低(因此更加健康)的食物，例如格兰诺拉燕麦卷或椒盐脆饼干，受试者却不愿付出这么多钱，这表明他们的渴望与通常意义上的饥饿有所不同。In a second experiment, the researchers repeated the process with 45 people. This time,however, indi

This time, the researchers found that people were also willing to paydisproportionately more for larger quantities of whatever food they desired.在第二项实验中，研究人员对45名受试者重复了上述过程。不过这一次，每个人可以花钱购买他们渴望的任意多
8、项食物。这一次，研究人员发现，人们愿意为喜欢的大量食物付出不成比例的更多价钱。Taken together, the results demonstrate the power of cravings whether for food orsomething else.两项试验的结果表明了渴望的力量一一无论是对食物还是对其他事物。zzEven if people strive to eat healthier or endorse drug-free lifestyles/ the researchers writein the paper, craving could overshadow
9、the value of health by boosting the value of unhealthyfoods or drugs/研究人员在论文中写道：即使人们努力健康饮食，避免吸毒，但他们的渴望也会提高不健康食品或毒品的价值，而让健康的生活方式较之黯然失色。On the bright side, however, the researchers estimated the effects of subjects cravingswould dissipate within two hours, and potentially less time if zzthis good is not available, or whena person engages in self-regulation/ If you,re able to wait it out, then, you may be able to resistthe lure of junkfood.不过，好的一面在于，研究人员估计这种渴望会在两个小时内消散，如果满足渴望的条件不足，或某人自制力很强，消散的速度会更快。因此，如果你能忍一会，或许就可以抵挡垃圾食品的诱惑。
