Question

【題目】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（代謝的）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（胰島素）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】這篇短文介紹肥胖是一個全球的問題，會增加一些疾病的風(fēng)險，雖然沒有公認的衡量健康的肥胖的措施，但是不會像以前那樣認為肥胖的人對健康有好處。

【1】詞義猜測題。根據(jù)第一段中的“those previously considered to be metabolically（代謝的）healthy”可知，曾經(jīng)肥胖被認為對健康有好處。推知“healthy obesity”指的是肥胖對健康有好處。故選A.

【2】推理判斷題。根據(jù)文中第三段中的“there are no accepted measures for measuring metabolically healthy obesity”可知，由于目前還沒有公認的對健康肥胖的衡量措施，因此導(dǎo)致了健康的肥胖沒有被證明是正確的。故選D.

【3】推理判斷題。通過對這篇短文的閱讀可以知道肥胖會增加一些疾病的風(fēng)險，雖然沒有公認的衡量健康的肥胖的措施，但是嚴重肥胖會對健康有害。推知，我們要知道不要讓自己過度肥胖，應(yīng)該保持平衡的體重。故選C.

【4】目的意圖題。這篇短文介紹肥胖是一個全球的問題，會增加一些疾病的風(fēng)險，雖然沒有公認的衡量健康的肥胖的措施，但是不會像以前那樣認為肥胖的人對健康有好處。所以推知，作者寫這篇短文的目的是呈現(xiàn)事實，通知大家和激勵人們注意肥胖問題。故選D.
