Once, I throw an orange skin into flowerpot, want to fertilizer can be made after waiting for it to decay. After a few days, because orange skin is lost a large number of water are divided and sere. But passed a few days again, the place that building orange skin originally appeared unexpectedly a green thing, and crossed that Xiaomiao a few days to grow taller more actually, still grew small leaf finally! Can how is orange skin gemmiparous?
有一次，我把一块橘子皮扔进了花盆，想等它腐烂后可以做肥料。几天后，橘子皮因为失去大量水分而干枯。但又过了几天，原本盖着橘子皮的地方竟冒出了一个绿东西，而且过了几天那棵小苗竟然越长越高，最后还长出了小叶子！可橘子皮怎么发芽了？
Original, there still is 9 oranges seed actually in the orange skin that begins me to throw most. After seed of those a few orange arrived in earth, outside that ivory film can be defeated slowly, seminal bud can come out. Because rotted orange skin makes fertilizer, let small Miao Ke compare faster ground in order to mix to appear from earth originally.
原来，最开始我扔的橘子皮里其实还有一两颗橘子籽。那几粒橘子籽到了土里后，外面那层乳白色的膜就会慢慢破开，种子的芽就可以出来了。因为有烂了的橘子皮做肥料，让小苗可以和原本相比更快地从土里冒出。
Pass this experience, and consult a few data on network and book, I knew seminal secret: The seed comes out from fruit, often can take an incrustation to protect kind of full marks / child. Fruit can be eaten to fall by the animal, the seed can leave as the excrement and urine of the animal inside animal body. Next the seed has peel, pulp or excrement and urine makes fertilizer, in incrustation or after film is defeated, the seed can sprout; Bud can grow a leaf, branch, bine slowly again, bud also can be brought up slowly. After bud is grown, with respect to meeting outcome. The decay after fruit be born, became again fruiter and new the nourishment of a batch of fruit and very much bodily form are differ, include our animal food ……
通过这次经历，以及查阅网络和书上的一些资料，我知道了种子的秘密：种子从果子里出来，往往会带着一层硬壳保护种满分/子。果子会被动物吃下，种子就会随着动物的粪便离开动物体内。然后种子有果皮、果肉或粪便做肥料，在硬壳或者膜破开之后种子就会发芽；芽又会慢慢长出叶子、分支、茎，芽也会慢慢长大。芽长大后，就会结果。果子落地后腐烂，又成了果树和新一批果子的养料和很多体型不一的，包括我们的动物食物……
Nature is such: The interest between everythings on earth is not mutual annex, give aid to each other however. much like the zebra can let a prairie degrade, can so the lion and hyena control the amount of the zebra, the nourishment of body melt into that stays after the lion, hyena and zebra are dead, below one year grass is gotten with respect to chairman more flourish!

自然界就是这样：万物之间的利益不是相互吞并的，而是相互扶持的。就像斑马多了就会让草原退化，所以就会有狮子和鬣狗来控制斑马的数量，狮子、鬣狗和斑马死后留下的尸体化为养料，下一年草就会长得更加茂盛！（作者系东北师范大学南湖实验学校404班学生，指导老师郭军）(文/贺沛东)
