There used to be many kinds of birds which are pests for protected crops. They are good friends at present.But the number of the birds has been greatly reduced because too much poison is used. As the result, the numberof the pests has increased.The peasants spent a lot of money and time in killing them every year.But it is still hard to eliminate them.Now you can see how poor it is for us to protect wild animals and to keep the balance of nature.Only that everyone know these can we live on a beautiful lives.

　　曾經有許多鳥類都能夠保護莊家，以防害蟲的侵害。他們是農民的好朋友。但是鳥類的數量正在急劇減少，這是因為人們大量使用農藥造成的。所以，害蟲的數量增加了。每年，農民都會花費大量經費，以及時間來消除害蟲。但是，人們還是很難將它們清除。如今，我們無法保護野生動物，并無法保持生態平衡。只有我們所有人提高意識我們才能過上幸福的生活。
