世界节假日博览 第113期:世界献血日

Millions of people are alive today because they received the blood given by another person. June 14 is World Blood Donor Day. This is the day on which we can say thank you to those who give blood. Every country raises awareness of the importance of giving blood. Most blood donors give blood voluntarily, but some countries pay for people to give blood. Doctors say the blood from unpaid donors is generally safer. The blood donation system is pretty much the same all around the world. You give blood and then get a free cup of tea, and perhaps a biscuit. There is a greater need for blood in developing countries. Under 40% of the world’s blood supply comes from the developing world, where 82% of the world’s population live.
通过献血，数百万生命得以挽救。每年的6月14日为世界献血日。我们要对献血者说声谢谢。所有国家都提高了对献血的重视程度。多数献血者自愿献血，但许多国家为有偿献血。医生称无偿献血者通常较为安全。全球献血体制几乎一样。献血后，工作人员会给你一杯免费茶，或许还有饼干。在发展中国家，对于血的需要尤为突出。对于发展中国家，全球血液供应量不到40%，而却占据了全球82%的人口。


Blood is, of course, the red liquid that makes some of us faint when we see it. It delivers oxygen and vital nutrients, such as glucose, amino acids, and fatty acids, to our body's cells. It also carries away waste products, like carbon dioxide, from our cells to keep our body clean. Seven per cent of our body weight is blood. The average adult has about five litres of blood. Our heart pumps blood around our body at high speed. It travels through a system of arteries and veins, that reach every part of our body. Our blood is made up of red blood cells, white blood cells and platelets. When we cut ourselves, it is the job of platelets to clot the blood to stop us bleeding. We all have one of four different blood types. If we are given a different blood type, we’ll die.
有人看见红色液体（血）会出现眩晕情况。通过血液传播，氧气以及像葡萄糖、氨基酸以及脂肪酸等重要营养物可传递到细胞中。它还可清除细胞中的废物，像二氧化碳等废物可通过血液清除，保持身体清洁干净。体重的7%为血液。成人平均血液含量为五升。心脏高速运转血液。穿过动脉和静脉系统流经全身。血液由红细胞、白细胞以及血小板组成。一旦身体被划破，血小板会帮助凝结血液，止住流血。人类共有四种血液类型。一旦血液不匹配，死亡情况就会发生。
