Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.张杨疑惑地看向黄豆，不知他问这个干什么，要问也该问他是否记得小时候的事。Created and guided by Coubertin, founder of the modern Olympic Movement, to measure the overall ability of athletes.在文明濒临灭亡的同时，战争和伴随而来的劳动力不足也促进了机械技术的进步结果，模仿人类的“人偶”被创造出来。　　该限定剧由Luke Davies及David Michôd执笔，讲述主角Yossarian（Christopher Abbott饰）在二战时的意大利，因为Cathcart上校（Kyle Chandler饰，原本由George Clooney饰演）的个人问题，他迫使下属飞行大队不停进行危险的飞行任务。而Yossarian原本想装疯来逃避任务，但他被告知军队所谓第二十二条军规虽然指疯子可免飞行，但得自行申请，然而「自行申请」一事却反证明申请者本人是理性下不想死，因此根本不是疯子，故该军规形同虚设。Army is the army; Castle is a castle; King is the king."Once upon a time, there lived a mother pig and its three piglets in a distant place. The mother pig was unable to feed the three piglets, so she asked the three piglets to go out and look for their own happiness."
