【简答题】
Health care is regarded as an important way to improve the health and well-being of people around the world. In many countries of the world, free health care is provided by the government. ___1___ Clearly, we all have to pay for this service through our taxes. ___2___ They say that people who take unnecessary risks should not receive this free health care. For example, people who join in risky activities such as skiing are more likely to have an accident. It has been suggested that these people should pay for any medical treatment they require. ___3___ Firstly, it’s difficult to say exactly what is risky and what is not. For example, not doing enough exercise is probably more risky than skiing in the long run. As a result, it isn’t fair to give free health care to an inactive person and make the skier pay. ____4____ Clearly, these people should receive free medical treatment if they are hurt on the job. Finally, I would like to say that I think free health care is a good thing. I understand that the system is not perfectly fair because some people use it more than others. Besides, not all the medical treatment is really necessary for the health of the patient. The taxpayer should not have to pay the costs of such treatment. ___5___ A. It helps you make money. B. Personally, I disagree with this point of view. C. However, some people think this is basically unjust. D. This means that everybody has a chance to see a doctor. E. Free health care will decrease the economy of the country. F. Besides, fire fighters take risks, but they are necessary risks. G. However, in my opinion, this is a small price to pay for a healthier society.
