Question

【題目】 Humans have four basic blood types: A, B , AB and O. Before doing blood transfusions(輸血), we have to check a person’s blood type and find out which kind it is. That is the most important step before a blood transfusion. But do you know that just like humans, animals also have blood types?

Dogs have eight basic blood types, though as many an twelve may exist. And a dog can receive any other dog’s blood for a transfusion if it is the first time. After the first time, it becomes important to check the blood type to prevent any risks.

Cats have three basic blood types, named A , B and AB. Of these three types, the A blood type is the most common. Almost 94 percent of the cats in theU.S.A have that blood type. And AB is a rare blood type.

Horse blood types are divided into eight major blood systems, namely A, C, D, K, P, Q, U and T. Cattle have eleven blood types and sheep have seven.

And surprisingly, plants seem to have blood types as well. A Japanese policeman accidently discovered this when he found an extra blood type at a crime scene. Certain proteins in plants are similar to those in human blood. Therefore, plants can also be divided into different groups according to their sap（汁液）. But scientists’ understanding of the blood types in plants is still at an early stage.
