Many people use wood stoves and fireplaces to heat their homes．Scientists have become worried about the smoke that they give off．Harmful chemicals are in the smoke．The smoke is causing air pollution．The pieces of pollution,called soot,are floating in the air．They are too tiny to see．Scientists must use a microscope to see them.
Small amounts of soot are safe,but large amounts can be dangerous．The govenment wants to limit this kind of pollution．It may stop people from using their fireplaces.
The air is tested every day．When soot levels are high,more than 65 micrograms of soot per cubic meter,factories must stop making smoke．The government thinks that limit should be much lower.
Factories produce the most smoke and soot．But the government thinks that all types of burning should be limited．The soot levels from factories and homes could be limited．Home owners may have to install new wood stoves that they comply with the new law．Or,they may not be able to bum on days when the air quality is bad.
Residents of some towns are fined if they violate the burning ban．Scientists hope these new regulations will make the air cleaner and less harmful to breathe.
What could home owners do to comply with the new regulation?
A、Write a lette
B、Ask for permissio
C、Use more electricit
D、Install new low-soot fireplace
【正确答案】：D
【题目解析】：根据文章内容，我们知道政府想要限制空气污染，尤其是由工厂和家庭燃烧产生的烟尘（soot）污染。为了遵守新的法规，文章提到“Home owners may have to install new wood stoves that they comply with the new law.” 这句话明确指出，家庭所有者可能需要安装符合新法律的新型木柴炉。
现在，我们逐项分析选项：
A. Write a letter（写一封信）：文章中没有提及写信作为遵守新法规的方式。
B. Ask for permission（请求许可）：虽然在一些情况下可能需要得到许可，但文章没有直接说明请求许可是遵守新法规的方法。
C. Use more electricity（使用更多的电）：虽然使用电是一种更清洁的能源选择，但文章中没有直接提到这是遵守新法规的方法。
D. Install new low-soot fireplace（安装新型低烟尘壁炉）：这与文章中的描述一致，即家庭所有者可能需要安装符合新法律的新型木柴炉。
因此，根据文章内容，家庭所有者可以通过安装新型低烟尘壁炉来遵守新法规，所以正确答案是D。
