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

Recently, we went on a vacation for a week that involved visiting four different ports in the sunny and warm climate of the Caribbean. There were of laughter, fun and great food. It’s a thing when you go away that each day of the vacation also to the end and a return to work.
It was twelve years since we went on a vacation, so this vacation was viewed with of a great break away from my daily routine. And we weren’t .
But there was something very different about this vacation compared to those when we worked in a corporative environment. The main was that when we returned, when the vacation was rapidly drawing to a close, we didn’t have the same feeling of stress, anxiety and fear.
In this recent vacation, it wasn’t that we enjoyed the various fun and new activities, the break away from routine, the pleasure of touring different countries and cultures, the to do what we wanted when we wanted or the leisurely of each day that was significant. What was significant was that we didn’t fear the last day of vacation. You see, we know that we were what we love to do not what we had to do.
The feelings experienced in the last couple of days of vacation were viewed with the same joy as the very first days. In the previous times, the last days of vacation were terrible. We experience an increasing of stress we knew that a return to our field of employment was “work” and not that we loved and thoroughly enjoyed.
The is this: If you do what you love, it doesn’t matter that a vacation has to end. If you love what you do you will not yourself wishing for even a few more days of vacation, or wishing that you could enjoying this vacation for much, much longer. A love of what you do you back like a magnet.

Does technology pose a threat to the purity of Chinese language?
Many Chinese use instant messenger tools such as MSN or QQ, listen to music on MP3 players and log on the Internet using ADSL—most without knowing the literal Chinese translation of the abbreviations(缩略词). But they don’t have to, as many English letters have become part of the local vocabulary.
A dozen abbreviations including GDP, NBA, IT, MP3, QQ, DVD and CEO are among the 5,000 most-frequently used words in the Chinese media last year, according to a report on the 2006 Language Situation in China.
The report said some parents are so keen on English letters that a couple tried to name their baby “@”, claiming the character used in email addresses reflects their love for the child. While the “@”is obviously familiar to Chinese e-mail users, they often use the English word “at” to pronounce it “ai ta”,or “love him”.
The study collected more than 1 billion language samples from newspapers, magazines, TV, radio and websites. The annual report is jointly compiled by the Ministry of Education and the State Language Commission.
“Nowadays, more and more English abbreviations are being used in Chinese, making them an important part of modern language,” said Hou Min, a professor at Communication University of China.
“The abbreviations have gained popularity because of the ease of usage,” Hou said. For example, DNA is much simpler to use than its Chinese version. “As more Chinese people learn foreign languages, especially English, in recent years, using abbreviations has become a trend among educated people,” she added.
Some language scholars fear such usage will contaminate(污染)the purity of Chinese and cause confusion in communication.
Which of the following is TRUE about the report on the 2006 Language Situation in China?
A.The report is compiled by the Ministry of Education alone.
B.The report is compiled every year.
C.The report is compiled every two years.
D.The report is based on over 1 billion language samples from websites.
Why does the author use the example of a couple who tried to name their baby “@”?
A.To show Chinese is badly polluted by English.
B.To express the couple’s love for the child.
C.To indicate “@”is a very common sign among the e-mail users.
D.To show some people are very enthusiastic over English letters.
Why are the English abbreviations becoming more and more popular according to the passage?
A.Because English is the most common language in the world.
B.Because using English abbreviations is a fashion.
C.Because English abbreviations are easy and simple to use.
D.Because English abbreviations are easy to pronounce.
What can we infer from the passage?
A.People should know clearly the exact Chinese translation of English abbreviations.
B.More and more Chinese people will use English abbreviations in the future.
C.Most parents like to give their child English names now.
D.Language scholars hate to use English abbreviations.
