Answer 1

Great changes have taken place in urban areas and in rural areas.We used to cook the meals with woods in countries.But now trees are cut down and we use marsh gas and natural gas in place.Meanwhile,in cities,because we usually used mine to make meals,the environment was not so good.But now we use electric and natural gas to cook the meals.The surroundings are getting better and better.
