 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 very glad to donate because they believe their blood can be helpful for others who are in need. 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.

经常可以看到很多的献血车停靠在路边，这样一来人们献血更方便了。一些人很乐意献血应为他们认为捐血能够帮助其他人。一些人却认为捐血可能会染上某种疾病。就我来说，我认为人们应该捐血。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，捐血可以让他人受益。通常，医院都需要准备大量的血给那些重症病人和那些发生意外的病人。因此，医院通常需要在血库里储备大量的血，以防万一。通过捐血，我们能够填补血库，让医生有足够的血液来拯救患病者。

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。持续捐血会提高造血机能。血液粘稠度会降低，血液流度会提高。这样一来，可以缓解或预防高粘血症。

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

总之，献血不仅能在一定程度上帮助他人，同时，我们也会变得更加健康。
