[单项选择]Whenever soup is served in the U. S., there’s a good chance that someone will shout "No soup for you!" in the best New York accent that he or she can master.
The line comes from Seinfeld, one of America’s most famous TV sitcoms. This, as well as others, has helped to preserve the "Noo Yawk" even as it evolves.
America has several distinct accents. The plain Midwestern accent is considered the standard American accent. It’s the one often heard on TV and radio. Northeastern cities such as Boston and Philadelphia, as well as the U. S. South, have their own ways of talking. None of these, however, carries the seemingly built-in drama of the New York accent. Perhaps that’s because of the conflicting traits that seem to possess it. All at once, the accent can make a person sound impatient and sarcastic, confident and in-charge.

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.
The subjects of the research tests conducted at the Copenhagen Central Hospital included_______.
A.elderly non-diabetic men
B.elderly type Ⅱ diabetic men
C.both sexes of all ages
D.both A and B
