[不定项选择题]共用题干 Exercise Can Replace Insulin for Elderly Diabetics
Most old 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 Berlingske 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.Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-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. 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.

[填空题]The New Math on Campus
Sexual Imbalance in Colleges
After midnight on a rainy night last week in Chapel Hill, N.C., a large group of sorority (女学生联谊会) women at the University of North Carolina squeezed into a basement bar. Bathed in a colorful glow, they splashed beer from pitchers, traded jokes and shouted lyrics to a Taylor Swift heartache anthem thundering overhead. As a night out, it had everything--except guys.
North Carolina, with a student body that is nearly 60 percent female, is just one of many large universities that at times feel weirdly like women’s colleges. Women have represented about 57 percent of enrollments at American colleges since at least 2000, according to a recent report by the American Council on Education. Researchers there cite several reasons: women tend to have higher grades; men tend to drop out in disproportionate numbers; and female enrollment leads further among older students, low-income students, and black students.
