43-46For many, summer is the time to shed the extra pounds piled on all winter. But for some of those trying to loseweight, there’s often this one spot on their body that just won’t let go of that fat. It turns out there’s a genetic reason forthis and the information is proving helpful to researchers trying to learn who is at risk for diabetes.Dr. Ronald Kahn, president of Boston’s Joslin Diabetes Center, says the research stems from basic questions peopleask of him. He explains, “People ask me as a diabetes and obesity expert, … ‘Doctor, why is it that when I gain weight italways goes to my belly?’ Or, ‘When I lose weight my face gets thin and my hips stay big?’”Kahn and his team have identified genes that match up to where our bodies store fat. Kahn said fat location is animportant risk factor in developing diabetes. He said, “When fat is inter-abdominal—that is, inside our bellies, theso-called beer belly type of obesity—this fat creates more insulin resistance. And remember that insulin is the majorhormone that controls our blood sugar.” He said doctors might one day be able to analyze someone’s genes and warnthose with the greatest disposition for large bellies.閱讀上文，回答第 43題至第 46 題
