When we donate blood, a small amount is usually taken in advance for at least ABO and Ph 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 rarest 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…
84 donors are Rh+ | 16 donors are Rh- |
38 are O+ | 7 are O- |
34 are A+ | 6 are A- |
9 are B+ | 2 are B- |
3 are AB+ | 1 is AB- |
1. Which of the following shown the correct relationships in blood transfusions?
A B A B A B A B
AB O AB O AB O AB O
A B C D
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

It is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.
How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs(破坏、毁灭)you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive (有建设性的)tools, you are going to be built up on them.
Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.
Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.

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 that 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 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, “Great game, isn’t it?” At bus-stops, people may comment about the transport system, “The bus service is terrible, isn’t it?”
Greetings and small talk are an important part of conversation in any language. The way people greet each other and the things they talk about, however, may be different from one language to another. This shows that there is much more to learn when we learn a language than just the vocabulary and the grammar of the language. We also have to learn the social behavior of the people who speak it.
1.Small talk is ________.
A. a kind of conversation with short words
B. a greeting when people meet each other

2.The passage suggests that when we learn a language, we should ________.
A. learn about the transport system of the country
B. only master the grammar and vocabulary
