Not long ago, I went to my uncle's house to play, he saw his house windows are arrayed on the balcony pots, some of which are planted with flowers and plants. I saw, on the uncle said: "uncle, almost into the botanical garden of your house." Uncle just smiled and said to me: "Plants are our lungs, although they sucked is carbon dioxide, but for us provided that sufficient oxygen. animals are not inseparable from them. "
Animals leaving plants, it can not survive? I began to have doubts and decided to do the experiment proved. I put my brother raised mice caught out. Let a little mouse called Huanhuan into a fish tank, and then quickly caught the plastic bag has much to offer, after the tank tightly, for fear of the air tank and the outside world. I carefully observed the side, I saw Huanhuan channeling in going forward. Hey, mice do not live very good for you? Is uncle wrong? After ten minutes or so, just so Huanhuan no longer active, a dying look. I moved a pot of lush vegetation, then change to a transparent large bowl, cover the plants with Huanhuan go. After a child, Huan Huan began to perk up. Did not want to die after a long look. This experiment proved that plants can transport animals need oxygen. To further demonstrate the dependence of animals on plants, I came to a large-scale factory. Where the air everywhere filled with a thick smoke, I can not breathe Xunde eyes. I quickly ran to the woods behind the factory, it is a place of fresh air, and I am extremely refreshing, smooth breathing.
This experiment demonstrates that plants can purify the air, people breathe. These two experiments show that animal survival and closely related plants. If the forests chopped down, the animal will be reduced by 90% to 70% of fresh water will flow to the sea, living with a 70% reduction in firewood, biological oxygen releasing 67% reduction, so that the plant is to protect the earth's green hero creatures on earth umbrella.
 前不久,我去舅舅家玩,看见他家窗口、阳台上都摆着花盆,里面都种着一些花花草草.我看见了,就对舅舅说:“舅舅,你家都快成植物园了.”舅舅只是笑了笑,对我说:“植物就是我们的肺,它们虽然吸进去的是二氧化碳,但却为我们提供的是充足的氧气.动物们都不得离不开它们.”
  动物离开植物后,就不能生存?我起了怀疑,决定做实验证明.我把哥哥养的小白鼠抓出来.让一只叫欢欢的的小老鼠进一个鱼缸,然后迅速将塑料袋大有作为套住,把鱼缸后得严严实实的,生怕缸里的空气与外界相通.我在旁仔细观察,只见欢欢在拼命向前窜.咦,小白鼠不活得挺好的吗?难道是舅舅说错了?过了十几分钟左右,欢欢不再像刚才那么活跃了,一副奄奄一息的样子.我搬来一盆茂盛的植物,然后换了一个透明的大脸盆,将植物连同欢欢盖进去.过了一会儿,欢欢又开始活跃起来了.过了好久也没有要咽气的样子.这个实验证明了植物可以输送动物需要的氧气.为了进一步证明动物对植物的依赖性,我来到一家规模大的工厂.那儿的空气到处弥漫着一股浓浓的烟味,熏得我不敢喘气睁眼.我急忙向工厂后面的树林跑去,那是一个空气新鲜的地方,我感到极为清爽,呼吸畅通.
  这个实验证明植物可以净化空气,使人呼吸顺畅.这两个实验证明,动物生存与植物有密切的关系.若把森林砍光,动物会减少90%,淡水的70%将流向大海,生活用薪炭减少70%,生物放氧量减少67%,所以说植物是保护地球的绿色英雄,是地球上生灵的保护伞.
