Exercise Can Replace Insulin （胰岛素 ） for Elderly Diabeties （糖尿病）

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 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 utilize insulin by 30 per cent， the newspaper reported.

This is equal tol 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 utilize 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 utilization 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 realize that they have to watch their diet while remaining unaware of the importance of exercise， Dela added.

Tatoo

Jack"s friend Tony had recently gotten a tatoo （文身） and Jack was so impressed by Tony"s bravery and his tatoo that he decided to get one， too. Why do a lot of young people in North America get tatoos today? Peer pressure， media influ.ence， and personal expression are some of the common reasons.

The desire to be part of a group， to be accepted by one"s friends or peers， can have a great influence on what a person does. Sometimes， wearing a tatoo can be a sign that you belong to a certaid group. Gangs often use special clothes and tatoos to identify their particular group. For example， in one gang all the members may wear green army jackets and have large"Xs" tatooed on their arms. It is not only gangs that have this type of special "uniform". Young people often belong to a certain group of friends. Some of these groups wear only brand-name clothes. Others wear tatoos. When a person"s friends are all doing something， such as getting a tatoo， that person is more likely to do the same thing， and get a tatoo too.

The media is another big influence behind the popularity of tatoos in North America. A wide variety of media images show tatoos. Tatoos can be seen on people appearing in commercials selling expensive cars. Famous sports heroes with tatoos are shown in magazines.

Fashion models are often seen in magazines and on TV wearing designer clothes that show their bodies tatooed with detailed and colorful patterns. These media， images link tatoos to ideas of wealth， success， and status. As a result， many people decide to get a tatoo for its fashion and status value.

It is not always the influence of other people or the media that results in a person getting a tatoo. Many people decide to wear tatoos in order to express their artistic nature， their beliefs， or their feelings- in other words， to show their individuality. A musician in a rock band may get a tatoo of a guitar on the arm. Some environmentalists may tatoo pictures of endangered animals on their shoulders. Lovers may tatoo each others" names over their hearts. A tatoo can be a public sign to show what is imPortant in a person"s life.

Jack got a tatoo because of __________. 查看材料

A.a desire to express himself

B.the influence of the media

C.the influence of friends

D.a desire to be fashionable

The Truth of American Health Care

Most people would be impressed by the high quality of medicine available to most Americans.

There is a lot of specialization， a great deal of attention to the individual， a vast amount of advanced technical equipment， and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly.

But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief， it is not just a free competition system. The private system has been joined a large public system， because private care was simply not looking after the less fortunate and the elderly.

But even with this huge public part of the system， which this year will eat up 84.5 billion dollars——more than 10 percent of the U.S. budget——large numbers of Americans are left out.

These include about half the 11 million unemployed and those who fail to meet the strict limits onincome fixed by a government trying to make savings where it can.

The basic problem， however， is that there is no central control over the health system. There is no limit to what doctors and hospitals charge for their services， other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache， a sick child， or a heart attack， all the unfortunate person concerned can do is pay up.

Two-thirds of the population are covered by medical insurance. Doctors charge as much as they want knowing that the insurance company will pay the bill.

The medical profession has as a result become America"s new big businessmen. The average income of doctors has now reached $100，000 a year. With such vast incomes the tall in the doctor"s surgery is as likely to be about the doctor"s latest financial deal， as about whether the minor operation he is recommending at several thousand dollars is entirely necessary.

The rising cost of medicine in the U.S.A. is among the most worrying problem facing the country.

In 1981 the country"s health cost climbed 15.9 percent——about twice as fast as prices in general.

In the U.S. patients can expect， in medical treatment，__________. 查看材料

A.occasional mistakes by careless doctors

B.a great deal of personal attention

C.low charge by doctors and hospitals

D.stacking nurses and bad services
