    In recent years, advances in medical technology have made it possible for doctors to extend people’s life to ma certain length. However, some people, including some doctors, are not in favor of these life-extending measures, and they argue that people should have the right to die when they want. They say that the quality of life is as important as life itself, and that people should not be forced to go on living when the conditions of life become unbearable. They say that people should be allowed to die with dignity(尊严)and to decide when they want to die. Others argue that life under any conditions is better than death and that the duty of the doctors is always to extend life as long as possible. And so that the battle goes on without a final answer.

    Little by little Americans are turning to solar power, tapping the strength of sun for energy. Solar energy is only in its infancy but already sun-light is heating, cooling or doing both for homes and office buildings mostly in the sunny southwest. Experts say all signs point to the birth of the solar energy industry. Right now, at least twenty-three companies are selling solar heat collector panels to heat and cool homes, or to heat water. The glass and metal panels cost from $ 100 to more than $ 500 each and the three-bedroom home usually requires a dozen or more. They look like sandwiches, or very narrow flower boxes, 3to 6 feet in width, 8 to 10 feet long, and 4 to 8 inches thick. They are usually place on roof tops., Nobody knows how many have been sold, and in addition, many people have built their own units. It has been estimated that solar power equipment will be a $ 1.3 billion industry by 1985, and more than a million homes will be plugged into sunlight for heat, air –conditioning or to generate electricity.
