You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB and O. A simple test can indicate a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.
Because of substances contained in each type, the four groups must be transfused carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group, hence it is often called the universal donor. For the opposite reason, AB sometimes called the universal recipient. However, because so many reactions can occur in transfusions, patients usually receive only' salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to avoid any bad reactions to the transfusion.
There is a relationship between your blood type and your nationality. Among Europeans and people of European ancestry, about 42 percent have type A while 45 percent have type O. The rarest is type AB. Other races have different percentages. For example, some American Indian groups have nearly 100 percent type O.

Historical Debate on Animal Experimentation
As the experimentation on animals increased, especially the practice of vivisection, so did criticism and controversy. In 1655, the advocate of Galenic physiology Edmund O'Meara said that "the miserable torture of vivisection places the body in an unnatural state." O'Meara and others argued that animal physiology could be affected by pain during vivisection, rendering results unreliable. There were also objections on an ethical basis, contending that the benefit to humans did not justify the harm to animals. Early objections to animal testing also came from another angle — many people believed that animals were inferior to humans and so different that results from animals could not be applied to humans.
On the other side of the debate, those in favor of animal testing held that experiments on animals were necessary to advance medical and biological knowledge. Claude Bernard — who is sometimes known as the " prince of vivisectors" and the father of physiology, and whose wife, Marie Frangoise Martin, founded the first anti-vivisection society in France in 1883 — famously wrote in 1865 that "the science of life is a superb and dazzlingly lighted hall which may be reached only by passing through a long and ghastly kitchen . Arguing that experiments on animals ...are entirely conclusive for the toxicology and hygiene of man ... the effects of these substances are the same on man as on animals, save for differences in degree, Bernard established animal experimentation as part of the standard scientific method.

听力原文： It is a great privilege for me to be invited to speak at the tenth year reunion of State University' s graduating class. When you arrived on campus today, after a decade, you were probably impressed by two changes at State:
one, the absence of University Tower, the first building constructed on the campus, and a historic landmark for many years; and two, the disappearance of parking lots on main campus.
Two years ago, University Tower was inspected and found to be unsafe. In spite of efforts to restore it, it was necessary to level the building. A bell tower was constructed on the same site, built for the most part using the good brick that was saved from the original building. The original bells were also preserved. As for the parking lots, they have been replaced by grass, trees, and pedestrian walkways. Parking is now located in parking garages on the North and West sides of the campus.
Two more subtle changes have occurred within the past decade. One is the creation and expansion of the Division of Continuing Education for the Community, including a Saturday and summer enrichment program for children, and an afternoon and evening special interest program for adult. The other is the addition of the student population of many young people from abroad, especially students from Japan, Latin America, and the Middle East, Most international students are enrolled in the College of Engineering and the college of Business.
And so, State is a different place, but like University Tower, it is built of the same brick. We are still committed to the same age old ideals "quality education for our citizens", but we have extended our commitment beyond the borders of our state and nation to encompass the citizens and nations of the world.
What is the occasion for the man's speech？
B．A class reunion.
C．The dedication of a new building.
D．The groundbreaking ceremony for a pedestrian walkway on campus.
