求翻譯:大氣污染源可分為自然的和人為的兩大類。自然污染源是由于自然原因如火山爆發,森林火災等而形成,人為污染源是由于人們從事生產和生活活動而形成。工業廢氣是人為污染的重要因素,除此之外,汽車尾氣也很污染空氣,因此我建議政府采取措施對這方面進行解決,盡量減少污染。在生活中,人們為了取暖燃燒煤等也污染空氣,在這方面我覺得的人們盡量用新型燃料,減少污染。是什么意思?![]() ![]() 大氣污染源可分為自然的和人為的兩大類。自然污染源是由于自然原因如火山爆發,森林火災等而形成,人為污染源是由于人們從事生產和生活活動而形成。工業廢氣是人為污染的重要因素,除此之外,汽車尾氣也很污染空氣,因此我建議政府采取措施對這方面進行解決,盡量減少污染。在生活中,人們為了取暖燃燒煤等也污染空氣,在這方面我覺得的人們盡量用新型燃料,減少污染。
