;Imagine you are sitting on a pile of money and can’t breathe for the thick dusty air is blocking your windpipe(气管).Imagine you have no clean water to use; instead，it’s just a dark and smelly liquid. That is what’s going;filter(过滤器) systems worth around $800/filter. Keeping the environment clean seems costly at first but it will benefit the economy afterwards. Industrialization has a great contribution to the growth of the economy but it also causes a lot of pollution which is the reason for global warming and climate change. The sudden change in the weather has made it hard for farmers to plant crops. Droughts，fires，floods andhurricanes are happening more and more often. According to Reuters，Indonesia lost 300,000 tons of crop production every year between 1992 and 2000，three times the annual loss in the previous decade due to the bad weather conditions. For countries that rely on agriculture for their economy，they won’t have enough products to export and therefore their economy will be slowing.;Another problem caused by air and water pollution is the price the companies have to pay due to health care and loss of workers. EPA data shows that 1 million tons of sulfur and nitrogen oxides(氮氧化物) in the air of a polluted city cause an average of 730 hospital visits and over 200,000 lost days of work each year. Not only do the companies lose their employees those days，but those companies have to pay their hospital bill. Then why not spend money protecting the environment and then benefit from it economically and enjoy a healthy life?;1.Keeping the environment clean seems costly at first and it won’t benefit the economy afterwards.(　　) 2.Industrialization has a great contribution to the growth of the economy but it also causes a lot of pollution.(　　) 3.The author suggests we spend money protecting the environment and then benefit from it economically and enjoy a healthy life.(　　);;;1.economy　　　　 A.n.责任，义务，本分 2.consultant B.n.&vi.辩论；争论，讨论 3.debate C.n.经济(情况)；经济体
