Question

【题目】The term "healthy obesity" has gained value over the past 15 years,but scientists have recently questioned its very existence."Our new findings suggest that health measures may be necessary for all obese（肥胖的）individuals, even those previously considered to be metabolically（代谢的）healthy,"says study first author Mikael,"Since obesity is the major driver changing gene expression in fat cells,we should continue to focus on preventing obesity."

Obesity has been a global problem,affecting approximately 600 million people worldwide and increasing the risk of heart disease,stroke,cancer,and so on.But in the 1970s and 80s,experts began to question the extent to which obesity increases the risk for these disorders.Later studies in the late 90s and early 2000s showed that some obese people show a relatively healthy life.

However,there are no accepted measures for measuring metabolically healthy obesity,and whether or not such a thing exists is now up for discussion."Our study suggests that the idea of metabolically healthy obesity may be more difficult than thought,"Mikael says,"There doesn’t appear to be a clear line that separates obese subjects with high or low insulin（胰岛素）sensitivity,indicating that obesity is the major driver explaining the changes in gene expression."

One limitation of the study is that it examined gene expression only in white fat cells,not other types.Moreover, all of the obese subjects were scheduled to experience obesity operations,so the findings may only apply to people with severe obesity.In future research,Mikael and his group will track the study patients after surgery to determine whether weight loss normalizes gene expression responses.They will also look for specific genes linked to improved metabolic health in these people.

In the meantime,the study has an important take-home message."Obese people may not be as metabolically healthy as previously believed,"Ryden says.

Answer 1

【答案】

【1】A

【2】D

【3】C

【4】D

【解析】这篇短文介绍肥胖是一个全球的问题，会增加一些疾病的风险，虽然没有公认的衡量健康的肥胖的措施，但是不会像以前那样认为肥胖的人对健康有好处。

【1】词义猜测题。根据第一段中的“those previously considered to be metabolically（代谢的）healthy”可知，曾经肥胖被认为对健康有好处。推知“healthy obesity”指的是肥胖对健康有好处。故选A.

【2】推理判断题。根据文中第三段中的“there are no accepted measures for measuring metabolically healthy obesity”可知，由于目前还没有公认的对健康肥胖的衡量措施，因此导致了健康的肥胖没有被证明是正确的。故选D.

【3】推理判断题。通过对这篇短文的阅读可以知道肥胖会增加一些疾病的风险，虽然没有公认的衡量健康的肥胖的措施，但是严重肥胖会对健康有害。推知，我们要知道不要让自己过度肥胖，应该保持平衡的体重。故选C.

【4】目的意图题。这篇短文介绍肥胖是一个全球的问题，会增加一些疾病的风险，虽然没有公认的衡量健康的肥胖的措施，但是不会像以前那样认为肥胖的人对健康有好处。所以推知，作者写这篇短文的目的是呈现事实，通知大家和激励人们注意肥胖问题。故选D.
