阅读段落

Our ‘dead’ products are ‘static’, closed systems. It is always the basicmaterial which constitutes the object and which, in the natural course ofthings, is worn down and becomes ‘older’. Ageing in this case must occuraccording to the laws of physical chemistry and of the thermodynamics. Althoughthe same law holds for a living organism, the result of this law is notinexorable in the same way. At least as long as a biological system has theability to renew itself it could actually become older without ageing: anorganism is an open, dynamic system through which new material continuouslyflows. Destruction of old material and formation of new material are thus inpermanent dynamic equilibrium. The material of which the organism is formedchanges continuously. Thus our bodies continuously exchange old substance fornew, just like a spring which more or less maintains its form and movement, butin which the water molecules are always different.

段落大意

本段对比了物品和生物体的区别：物品只是静态的，关闭了的系统;生物体是一个开放的，动态的系统，体内的新物质会不断地代谢。
