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.3.1 Create syntax as follows　　藤田英作为了那张藏宝图，不惜让自己的情人佐佐木澄江和沈家康结成姻缘，并生下了一个女儿千香子。面对亲人又不能相认的沈家康，利用调虎离山之计将沈氏两姐妹安全地送到了香港。藤田英作计划把佐佐木和千香子作为人质，进而诱捕沈家康；佐佐木拜托毕加带着千香子逃到香港。　 监狱的典狱长温特上校素以严酷的铁腕政策而著称，起初，埃尔文对这位富有传奇色彩的上校颇为崇敬，但在埃尔文表达出他对典狱长管理方法的不满之后，这种崇敬就演变成了一种敌意和仇视。埃尔文与腐败的典狱长开始了公开的对峙，日趋激烈的对峙最终引发了一场声势浩大的越狱行动：埃尔文指挥着自己招募起来的“新军”——1200多名狱友，掀起了推翻典狱长统治的大战。很快中午就到了。Zhou Bichang
