【正确答案】
In many people’s minds，countryside means a place with green trees，flagrant flowers，clear rivers and blue sky，but the notion is changing with the development of urbanization and industrialization．Trees and flowers become fewer，rivers are stagnant and the sky turns blurry due to pollution．Countryside does not look like the beautiful one in our memory．Our countryside is disappearing．
Nowadays，people in the whole world are highlighting urbanization and industrialization，considering them as the synonyms of prosperity and advance，in spite of the cost they should pay for that．Tim generous nature gives us the pleasing natural environment for free，but human beings return her kindness with greed and malice．When pursuing practical profits，they destroy a lot of beautiful natural environment，never realizing its value，until they ruin the last clean pitch on the earth and draw disasters，like landside，flood and desert to themselves．How pathetic they are!
It’s urgent for us to take some measures to protect our countryside--the last paradise for human beings． We should return farmland to forest，plant more trees，stop dumping waste water into rivers，and severely punish those who kill endangered animals．Now，it is our last chance to keep our countryside from disappearing．
