Don’t choose a rather difficult book or a too easy one for yourself to read. A book full of new words will make you feel discouraged quickly. To understand those new words, you have to turn to the dictionary quite often. .A too easy one will only waste your time and cannot do any help. The two extremes may at last make you give up reading. So it’s better for you to find a proper book with no more than five new words on each page.

If you come across a new word, do not look it up in a dictionary at once.Leave it alone and guess the meaning of it based on the content of the text. This ability is quite necessary in reading. If you know your guess is right later, you will be highly excited at your “success”, and your interest in reading is well encouraged. If a word really prevents you from understanding the whole passage, turn to the dictionary by then. I am sure you can remember this word very well, as it has left you such a deep impression for its “troublesome image”.

To comprehend what you are reading, you should think while you are reading, then form your own ideas. Your writing does not need to be quite formal but expressive. This practice can make you communicate with the original English authors. Day by day, your way of thinking in English will turn into a native way, which is quite important for English writing.

Language has its own beauty, no matter Chinese or English. Don’t merely take English as a “test”. Take it as an “entertainment” instead and you will enjoy it through learning. Maybe you should find some beautiful literary works such as a prose or a poem to read, if you like. Try to read them as loudly as you can. During this process, not only you can enjoy yourself by the great emotions of the writers, but also your pronunciation and your manner of speaking English will be improved.

The last but not the least, keep on reading. If you cannot keep it as a habit, you will suffer from paying without gaining.
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…
