本市无偿献血日即将来到。你应《21世纪报学生版》之邀，与同学们讨论之后写一篇宣传稿，向全校师生宣传无偿献血的重大意义及其对身体的影响。大意?如下：
血液是人体不可缺少的东西。它将养分和氧气输送到体内各个组织，同时将废物和二氧化碳运走。一个人如果失血过多就会死亡。输血这一措施正在挽救着千百万人的生命。无偿献血是高尚之举，它体现了献血者对他人的关爱。目前许多国家广泛开展无偿献血，我国也提倡这一活动。
献血不会损害献血者的健康。首先，只有健康的人才有资格献血；此外，每次的献血量很少，献血者身体会很快进行调整，使身体机制正常运转。
参考词汇：nourishment养分 transfusion输血 donation捐献 adjustment调节，调整

[阅读材料]
As is obviously revealde in the bar chart above, over the past seven years(1998-2004), the proportion of free blood donation in clinical blood collection has been climbing and rocketed to over seventy percent in 2004, which is a welcome development to our whole society．
The implied meaning of the bar chart above can be illustrated as follows．To bengin with, the increasing percentage indicates that great changes have taken place in terms of people’s spirtual civilization．Most people want to make contribution to our society in one way or another which is a way to realize self-value．The spirit of selflessness is more pervasive than ever before．What’s more, the statistics betray that modern people, especially the young, jave a better understanding of medical knowledge．Most people have abandoned their old idea that blood donation is most harmful to human body．In one word, word our spirtual progress and rich medical knowl-edge have resulted in such a positive result．
In my view, effective measures should be taken to encouragefree blood donation．First of all, a nation wide education campaign should be launched to spread the necessity and knowledge of free blood donation．Besides, we should be set up to protect those who donate blood．Only in this way can we create a harmonious and healthy society．
