Passage Four
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.
48. A good title for this passage is______.
A. Getting Blood and Plasma
B. Special Blood and Colors
C. Human Blood Types
D. The Blood Bank of a Hospital

There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he didn't know the sub-group. He reported the outbreak to the World Health Organization in Geneva. WHO published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%~20% of the population had become ill.
As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs used against all the known sub-groups of type A virus. None of them gave any protection. This then, was something new; a new influenza virus against which the people of the world had no ready help whatsoever.
Having isolated the virus they were working with, the doctors now conducted tests on some specially selected animals, which contracted influenza in the same way as human beings did. In a short time the usual sign of the disease disappeared. Theses experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply "Asian" flu.
The influenza discovered by a doctor in Singapore is caused by ______.
A.a new type of virus
B.type A virus
C.a sub-group of type B virus
D.a virus only existing in Asia
第10题
Ineffective communication can be disastrous.There is a famous story of a British Army Commander who sent the message "Send reinforcements,we're going to advance." back to his Command Center,through a long chain of subordinates.When the message finally reached the Command Center,it had "mutated" to become -- "Send three and four-pence,we're going to a dance." The reinforcements never arrived.
You can demonstrate this same principle,albeit on a less dramatic scale,by trying to play Chinese Whispers with more than 20 people.It is highly unlikely the same message you started with will be the one you end with.
In a business,there are three main types of communication failure.Each has its own indicative signs.
•The first type is known as allocative failure.This occurs when a firm is not gathering enough intelligence about its market or (most often),the information is not reaching the right points.The firm will not be allocating resources in step with the shifts in demand.If demand is rising but the firm is suffering from allocative communication failure,then stocks will fall and there will be understaffing.If the inverse happens,there will be a surplus of stocks and overstaffing.
•The second type is executive failure,where communication to trigger specific events/actions is either late,lacking or in error.The symptoms of this are a general loss of direction in the company or departments,a loss of co-ordination and an increase in complaints from customers as things happen late or not at all.
•The final type is human failure.This occurs when the general culture of a business or the relationships between particular individuals or departments do not foster effective communication.This leads to alienated staff,an increase in staff turnover,an increase in absenteeism and general frustration among staff.Creativity,especially that which takes place across departmental boundaries,is likely to suffer hugely as team synergy slips.
