When we donate(捐献) blood, a small amount is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.
The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物质) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The least common is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world.
1.Which of the following shown the correct relationships in blood transfusions?
2.The underlined word “transfuse” most probably means ________.
A. to put the blood into a container
B. to move the blood from one place to another
C. to put the blood of one person into the body of another
D. to give power to another person
3.The writer suggests that the third most common blood type among the Europeans is ______.
A. B B. A C. AB D. O
4.The text mainly tells us ______.
A. about the basic types of human blood
B. what kind of blood is the most common
C. about Karl Landsteiner who won the Nobel Prize
D. the relationship between blood type and nationality

In most languages, a greeting is usually followed by “small talk”. Small talk means the little things we talk about at the start of a conversation. In English-speaking countries people often make small talk about the weather. “Nice day, isn’t it?” “Terrible weather, isn’t it?”. But there is something special about small talk. It must be about something which both people have the same opinion about. The purpose of small talk is to let both people agree on something. This makes meeting people easier and more comfortable. People usually agree about the weather, so it is a safe topic for small talk. But people often disagree about religion(宗教)or politics so these are not suitable topics for small talk in English. The topics for small talk also depend on where the conversation is taking place. At football matches, people make small talk about the game they are watching: “A great game, isn’t it?” At bus-stops, people may talk about the transport system(体制): “The bus service is terrible, isn’t it?”
