问题 共用题干Exercise can Replace Insulin for Elderly Diabetics
Most older people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlin gske Tidende on Monday.
Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.
This is equal to the effect most elderly diabetics get from their insulin medication today, it said.
Researchers had a group of non-diabetic men and a group of men with type Ⅱ,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.
Associate Professor Dr. Hemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non一exercising persons.
“This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,”Dela was quoted as saying.
Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise.
Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.
选项 How could most elderly type Ⅱ diabetics stop taking insulin?A: By taking more salt than usual.B: By taking less salt than usual.C: By doing brisk exercise for half an hour at least three times a week.D: By going climbing,swimming or boxing every day.
答案C
解析题干意为“大多数上了年纪的Ⅱ型糖尿病患者怎样才能停止使用胰岛素？” 短文标题直接点明了短文的主题——老年糖尿病患者可以通过体育锻炼来取代胰岛素治疗，因此与体育运动相关的选项C和选项D可能是答案。比较这两个选项：C项“通过每周三次轻快的体育锻炼，每次30分钟”,D项“通过每年爬山，游泳或拳击”，依据常识，老年人不适合做拳击运动，因此答案可能是选项C。其实短文第一段就是该问题设置的依据，第一段提到“一则最新医疗研究结果称，大多数Ⅱ型老年糖尿病患者只要每周坚持三次轻快的体育锻炼，每次30分钟，就可以不用注射胰岛素”。由此可以进一步确认答案为C。 题干意为“体育锻炼可以把身体利用胰岛素的能力提高多少？”利用题干中的细节信息短语physical exercise, body ability作为定位线索，备选项中出现了大量的数字，也利用备选项中的数字作为定位线索，这样在短文第二段中找到相关句：Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed'hat [u]physical exercise[/u] can boost the [u]body's ability[/u] to utilise insulin by [u]30 percent[/u], the newspaper reported．该句提到“报道称，哥本哈根中心医院Rigshospitalet肌肉研究中心对糖尿病人进行测试，结果显示体育锻炼能将身体利用胰岛素的能力提高30%”。由此答案为B项。 题干意为“在哥本哈根中心医院进行的研究实验所涉及到的研究对象包 括……”。利用题干中的细节信息词/短语subjects,research tests, Copenhagen Central Hos-pital作为定位线索，在第四段中找到相关句：Researchers（指上文中提到的哥本哈根研究中心 的研究人员）had a group of [u]non-diabetic men and a group of men with type Ⅱ ,all more than 60 years of age[/u],exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked，第四段第一句提到“研究人员挑选了一组非糖尿病患者，一组Ⅱ型糖尿病患者，都在60岁以上的男性。这些人每周骑自行车锻炼六次，并持续三个月”。由此可知答案为D项“老年非糖尿病男性和老年Ⅱ型糖尿病男性患者”。
