Another factor could be the increased mechanization(机械化) of farm work,Befort said.Older generations showed less difference in weight than younger ones—older farmers would have put in more physical labor,she said.
“Although some intervention(介入) research has begun to address
obesity among rural adults and families,great attention needs to be focused on widespread effective programs in rural areas,which contain some of the largest medically underserved communities in the nation,” the researchers said.
【语篇导读】 肥胖症的研究有了新的发现——居住地也是造成肥胖症的重要因素。39.6%的美国乡下居民患有肥胖症,这与油腻的饮食、农场机械化、落后的医疗服务等有很大的关系。
1.What do we know about the study about weight in the passage?
A.The new study is the first study of rural obesity in the past 30 years.
B.The new study is the first time to research into the cause of obesity.
C.Results in the past years can be inaccurate as they haven't adopted actual measurements.
D.The result of the new study is not reliable at all.
解析 推理判断题。根据第三段可知,这个研究分析了国家健康中心的数据,是近30年来第一次使用身高和体重的实际测量数据,而不是使用未必可靠的“自我报告的数据(selfreported data)”,从这些信息可推知,过去的研究数据不是很准确,不太可靠。因此选C。
