雅思口语：口语中关于有没有大肚腩是基因决定
Beer lovers around the world raise your glasses--it might not only be how much you drink that determines the size of your beer belly, it could be your genes.
全世界的啤酒爱好者可以举杯庆祝了：你的啤酒肚尺寸不光取决于你喝了多少，这其中可能还有基因的作用。
A team of Italian scientists has linked a gene, known as DD and present in about 40 percent of the population, to abdominal weight gain in men.
意大利一个科研小组已经发现了男性腹部增肥与一种基因之间的关联，大约有40%的人携带着这种名为DD的基因。
# r: ~' I5 X1 Y9 D/ M3 _In a study published in the medical journal, Annals of Internal medicine, researchers monitored some 300 male factory workers over a 20-year period and found that DD carriers put on 50 percent more weight--an average 9.9 pounds against 6.6 pounds for non-carriers. "some people, despite their sacrifice of looking at calories and trying to exercise as much as they can, tend to put on fat because they are genetically susceptible," research leader Pasquale Strazzullo, from the Federico II University of Naples Medical School, told reporters.
' {- s" F" ?, D9 a6 W研究者们对大约300名男性工人进行了为期20年的监测，发现DD携带者增加的体重比非携带者多出了50%——平均9.9磅对6.6磅。他们的研究结果发表在医学杂志《国际医学年报》上。研究主持者、那不勒斯费德里哥二世大学医学院的帕斯夸里·斯特拉祖罗对记者说：“有些人时刻关注着卡路里，尽可能多地进行锻炼，这样的代价也不能阻止体重增加，因为基因决定了他们容易长胖。”外语学习网
( L& w" V  Q0 X5 jThe first set of figures collected in 1987 did not include waist measurements, so in the 1996-97 data gathering Strazzullo took this measurement and widened his sample to about a thousand workers to calculate more accurately just how much bellies had ballooned.
