Abstract: "We have always learned crotch start and forward roll from primary school to university." Students' complaint sounds sarcastic, but it makes P.E. teachers at primary school, middle school and college complain to each other and puts P.E curriculum designers in embarrassment. As a result, the logicality and scientificity of P.E. curriculum are doubted and P.E.'s qualification as a discipline is questioned. Much research has been done on P.E. cohesive P.E. curriculum arrangement from primary school through middle school to college and some solutions have been proposed, such as the solution of achieving cohesion in both content and difficulty, the solution of pursuing physical fitness and development, the solution of pursing physical development while highlighting cohesion of key aspects, and the solution of replacing content cohesion with objective and evaluation logic. However, years of research has yielded neither convincing and scientific hypothesis, nor scientific demonstration and experiment on the cohesion of P.E. curriculum from primary school through middle school to college and its logic. The superficial reason of this predicament is P.E.'s peculiarity as a discipline, while the underlying reason is the impossibility that all students from all over the country learn the same sport. The above shows that it is impossible to arrange a cohesive P.E. curriculum that is suitable for all students.

Key words: cohesive P.E. curriculum from primary school through middle school to college, logic of cohesive curriculum for all students at different school stages, logic of cohesive curriculum for individuals at different school stages, ideal lifelong sport image, optional specialized P.E. teaching, "optional class system"teaching at compulsory education stage, modular teaching at senior high school, "three independences"teaching at college
