英语翻译
Throughout history man has had to accept the fact that all living things must die.But people now live longer than they used to .Yet,all living things still show the effect of aging,which will eventually result in deaths.,the body and the organs they form do not function as well as they did in childhood and teenage years.The body provides less protection against disease and is more prone to accident.
A number of related causes may contribute to aging.Some cells of the body have a fairly long life,but they are not replaced when they die .As a person ages,the number of brain cells and muscle（肌肉） cells decreases.Other body cells die and are replaced by new cells.In an aging person the new cells may not be as workable or as capable of growth as those of a young person.
Another factor in aging may be changes within the cells themselves.Some of the protein chemicals in cells are known to change with age and become less elastic（有弹性的）.This is why the skin of old people wrinkles（皱纹）and hangs loose .This is also the reason why old people shrink in height.There may be other more important chemical changes in the cells.Some complex cell chemicals,such as DNA an RNA,store and pass on information that the cells need.Aging may affect this process and change the information-carrying molecules so that they do not transmit the information as well.

纵观历史,人们不得不承认凡是生物就会灭亡的现实.但是人们的寿命比过去长了.然而生物仍然会变老,最终死亡.身体和器官的功能不及童年和年轻时候.身体的免疫能力下降于是更容易发生事故.
大量的事故是由衰老造成的.一些细胞确实有很长的寿命,但是它们死去后不能再生和替代.当人们变老的时候,一些脑部细胞和肌肉细胞逐渐减少.其他身体细胞死去并由新的细胞代替.一个正在衰老的人不像一个年轻人的细胞更新的更快更有效.
衰老的另一个因素可能存在于细胞自身的变化之中.细胞中的一些蛋白质随着年龄的改变而活性下降.这就是为什么老年人的肌肤有皱纹而皮肤松弛.这也是老年人个子变小的原因.细胞中可能还存在其他化学变化像是DNA RNA的变化,存储和传递细胞需要的信息.衰老可能影响这个过程并且改变传递信息的分子以至于它们不能更好的发送信息.
