What is the most beautiful language in the world?A smile!But how can we make the earth smile?That is the big question for us to answer.
Animals and plants are dying one by one.The earth is crying.It's time for us to take care of her,because we have only one earth.Let's start now!
The earth used to be a colourful world.But now there is so much killing (杀戮) in it.There are wars (战争) between people here and there.We need a peaceful (和平的) world!
Animals and plants are our friends and we should live with them peacefully on the earth.However,unfortunately(不幸地)human beings have done a lot to harm our friends-- animals and plants.The earth becomes more and more polluted by the economic development of human beings and as a result,many animals and plants become extinct(灭绝)because of the worse conditions(环境)of the earth.We should stop the pollution and make this planet(行星)a better place for all of us including ainmals and plants to live well.
