It is often seen that many donation cars park along road so that it would be convenient for people to donate blood.

Some people are reluctant to donate their blood for they hold that they may be infected with other disease. In my opinion, I think people should donate blood. Reasons are as follows.

經(jīng)?？梢钥吹胶芏嗟墨I血車?？吭诼愤叄@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。

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

首先，捐血可以讓他人受益。通常，醫(yī)院都需要準備大量的血給那些重癥病人和那些發(fā)生意外的病人。因此，醫(yī)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(yī)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 our hematopoietic function will be strengthened. So the blood viscosity will be lower and the velocity of blood flow will speed up. Consequently, it will help people to relieve or prevent high blood viscosity.

第二，捐血可以更健康。持續(xù)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 can we 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。
