20．Once，there was a little grey planet．People living on it hadn't looked after it well．Although they had all kinds of inventions and spaceships beyond our imagination，they made the planet full of rubbish and pollution．As a result，there were no plants or animals left．One day，a little boy was walking on the planet．When he passed a cave（山洞），he noticed a small red flower in it．The flower was sick．It was almost dying．The boy dug it out carefully with oot and some soil．Then he tried to find somewhere to plant it．After he searched all the planet，there is no proper place because of rubbish and pollution．He looked up in the sky and he found the moon．He thought the flower might grow well on the moon．So he climbed into a spaceship with the flower and flew to the moon．He grew the flower on the moon and looked after it every day．The flower started to grow so well that several days later it gave birth to many little flowers．Soon these flowers spread all ver the moon and the moon was covered with red flowers．
When the flowers open，the moon looks red，like a warning light．If we don't look after our earth，the day will come when flowers will only be able to grow on the moon．

15．Just about everything you do leaves a"carbon footprint （碳的足迹）"．For example，when you travel in a taxi，the car gives off carbon dioxide （CO2） into the air．Carbon dioxide is a greenhouse gas．Greenhouse gases make the earth become warm．To protect our environment，we need to leave less of a"carbon footprint"．
How big is your carbon footprint？To get an idea，take a look at the following numbers．
*TV sets and DVD players produce 723kg of CO2 a year．
*If you use your dryer machine five times per week，you produce 185kg of CO2 per year．
*If you take an eight-minute shower every day，you produce 616kg of CO2a year．
Surprised？Well，here's how you can work to reduce it：
Eating
*Each week，choose a day not to eat meat．Meat uses up lots of energy because it takes a long
time to produce．
*Do not waste food．Ask to take food home from restaurants if there's any left．
At home
*Save energy by using efficient light bulbs．Turn off the lights when you leave．
*Take short showers rather than baths．
*Dry your clothes in the sun instead of in a dryer machine．
At school
*Only print things out when necessary，and print double-sided．
*Don't use disposable （一次性的） cups or boxes．Take your own cups and lunchboxes to school．
