It is often seen that many donation cars park along road sothat it would be convenient for people to donate blood. Some people are veryglad to donate because they believe their blood can be helpful for others whoare in need. Some people are reluctant to donate their blood for they hold thatthey may be infected with other disease. In my opinion, I think people shoulddonate blood. Reasons are as follows.

經常可以看到很多的獻血車停靠在路邊，這樣一來人們獻血更方便了。一些人很樂意獻血應為他們認為捐血能夠幫助其他人。一些人卻認為捐血可能會染上某種疾病。就我來說，我認為人們應該捐血。原因如下。

Firstof all, donating blood will benefit others. Generally, hospitals need lots ofblood for those critically ill patients and those who have accident. Hence,hospitals will store amounts of blood in blood bank incase of emergency. By donating blood, we can fill the blood bank and ensuredoctors enough blood to save patients’ life.

首先，捐血可以讓他人受益。通常，醫院都需要準備大量的血給那些重癥病人和那些發生意外的病人。因此，醫院通常需要在血庫里儲備大量的血，以防萬一。通過捐血，我們能夠填補血庫，讓醫生有足夠的血液來拯救患病者。

Secondly,we will be healthier by donating blood. If we keep on donating blood, then ourhematopoietic function will be strengthened. So the blood viscosity will be lower and the velocity of blood flow willspeed up. Consequently, it will help people to relieve or prevent high blood viscosity.

第二，捐血可以更健康。持續捐血會提高造血機能。血液粘稠度會降低，血液流度會提高。這樣一來，可以緩解或預防高粘血癥。

 In conclusion, by donating blood, not only canwe help others to some extent, but also we can be healthier.

總之，獻血不僅能在一定程度上幫助他人，同時，我們也會變得更加健康。
