But it is definitely not a dog's strange thing. Apart from being large in quantity and fast in speed, In addition to a very strong sense of attack, There is still some tactical nature, In the words of my teachers at the military academy, 'Tactical awareness is a further sublimation of basic organization', I feel it is most appropriate to use this word on these strange things. They know that they are surprised and flank while attacking the front. I also assumed that they were trained by the Vietnamese army, but I didn't think of a clue and didn't continue to think about it.赵晨、古丽红和叶茂是三个出类拔萃，智商、情商都很高的都市丽人，同在一家报社的新闻部当记者，形影不离，被人戏称为“三套车”。虽然三人都已年近三十，但却始终没有勇气走进婚姻的“围城”，她们在爱情与事业中自由飞扬。忽一日，古丽红宣布她将嫁给拍拖多年的男友宋海东，率先打破了“三套车”的平衡。 几乎在同时，一个身患脑瘤的年轻姑娘丫丫一头闯进了赵晨和陆子健的生活。这个美丽、纯真的姑娘在生死关头拨通了陆子健主持的电台谈心节目热线，并对他产生了强烈的依恋之情，赵晨洞悉到这一切，她以一片爱心包容了丫丫的这一份情，与陆子健一起全力救助丫丫。丫丫手术失败，即将走到生命的终点，为点燃她最后的生命之光，陆子健作出了一个抉择：与深爱自己的丫丫结婚，年轻的丫丫马上就要穿上婚纱成为新娘…… 叶茂以“小龙女”为代号，在网上与一个叫做“10号”的先生撞出一段情缘。赵晨和古丽红经过策划，The second classification principle of organisms is the lineage classification principle aiming at establishing evolutionary lineage. The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.
