【1】　Effects of Exercise on Elderly Diabetics (糖尿病人)

　　Most older people with so-called type 2 diabetes (糖尿病) could stop taking insulin (胰岛素) if they would do brisk (轻快的) exercise for 30 minutes just three times a week， according to new medical research results reported in a Copenhagen newspaper. 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 make use of insulin by 30 per cent. This is equal to the effect most elderly diabetics get from their insulin medication (药物治疗) today.

　　Researchers had a group of non-diabetic men and a group of men with type 2 diabetes， 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 make use of 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 made as good use of insulin as the healthy non-diabetic 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，” Dela said.

　　Insulin is a hormone produced by the pancreas (胰腺)， controlling sugar in the body and is used against diabetes.

　　Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to 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.

【2】　Giving Up Smoking

　　A number of devices are available to help a person quit smoking. Nicotine (尼古丁) patches are small， nicotine-containing adhesive (粘着性的) discs applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream (血流)。 Over time， the nicotine dose is reduced and eventually the desire for nicotine is eased. Nicotine gum (口香糖) works in a similar manner， providing small doses of nicotine when chewed (咀嚼)。

　　The benefits of giving up smoking include the immediate reduction of harm to the health of the smoker and easier admission to social activities and institutions that ban smoking. In a 1988 report， the U.S. Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine (可卡因)， alcohol， or heroin. Recent evidence supports this claim.

　　The United States government has collected a special tax on cigarettes for several decades. The rate rose from 8 cents per pack of 20 cigarettes in 1951 to 24 cents per pack in 1993. In other developed countries， the cigarette tax rate is much higher， ranging from 50 percent in Switzerland to 85 percent in Denmark.

　　In the United States， the first direct action to check smoking was the regulation of a warning on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read： “Warning： The Surgeon General Has Determined That Cigarette Smoking Is Dangerous to Your Health.” In 1971 all cigarette advertising was banned from radio and television， and cities and states passed laws requiring nonsmoking sections in public places and workplaces.

　　1 Which of the following can help a person quit smoking?

　　A Reading cigarette advertisements.

　　B Using nicotine patches.

　　C Chewing ordinary gum.

　　D Participating in social activities.

　　2 Nicotine gum is used to help a smoker

　　A reduce weight.

　　B stop smoking.

　　C clean his teeth.

　　D absorb nicotine immediately.

　　3 The benefits of giving up smoking include all the following EXCEPT

　　A the formation of a good habit.

　　B the reduction of expenses.

　　C the reduction of harm to one's health.

　　D easier access to institutions that ban smoking.

　　4 Which of the following is said to be the most expensive and harmful?

　　A Consuming alcohol.

　　B Using heroin.

　　C Taking cocaine.

　　D Smoking cigarettes.

　　5 Which of the following is NOT mentioned as a step to control smoking?

　　A Forbidding smoking in all public places.

　　B Collecting a special tax on cigarettes.

　　C Banning cigarette advertising from radio and TV.

　　D Requiring a warning on each cigarette package.
