and twelve million golfers.These figures would not surprise most people.But many would be surprised to learn that twenty million Americans ride motorcycles (摩托车).Few people realize that motorcycling is fast becoming one of America’s most popular sports.

According to the Cycle News，many kinds of people enjoy motorcycling.They include black people and white people, businessmen, professionals, and blue-collar workers.Among them, about 55% are businessmen, 3% are in the professions and 9% in government service.

Such information is offered by the Cycle News in the hope of improving the general public’s impression of the sport.The public has tended to believe that all motorcyclists are wild and lawless young men.

There are several things about motorcycling that the average citizen dislikes.A motorcyclist’s appearance has something to do with this dislike.Motorcyclists often look dirty; in fact, they are dirty.On the road, there is little to protect them from mud.For practical reasons, they often dress in old clothing which looks much less respectable than the clothing of people who ride in cars.For the same reason, motorcyclists usually wear dark colors.Perhaps this helps to explain why they are sometimes suspected of having bad natures.

Probably motorcycles themselves also produce anger and fear.They are noisy， though some trucks are even noisier.But trucks are acceptable because they perform. a needed service.Motorcycles, on the other hand, make an uncomfortable noise just to give their riders pleasure.Roaring along quiet streets, they wake sleeping families and make babies cry.

Yet, as motorcycling becomes more and more common, it will be interesting to see how people in general feel about the sport.Perhaps it will someday become as “respectable” as tennis or golf.

be an optimist (乐观者), a leader, and an active person who enjoys life, people and excitement.Do you prefer grays and blues？ Then you are probably quiet, shy and you would rather follow than lead.You tend to be a pessimist.At least, this is what psychologists (心理学家)tell us, and they should know, because they have been seriously study ing the meaning of color preference, as well as the effect that colors have on human beings.They tell us among other facts, that we do not choose our favorite color as we grow up — we are born with our preference.If you happen to love brown, you did so,as soon as you opened your eyes, or at least as soon as you could see clearly.

Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Light and bright colors make people not only happier but also more active.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or gray.

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

ed States and spread to Canada, Great Britain, and many other countries. The hippies rejected the customs, traditions, and life styles of society and tried to develop those of their own. Most hippies came from white middle-class families and ranged in age from 15 to 25 years old. They thought too many adults cared about making money and little else. The term hippie may come from the word hip, which means "turned-in" or aware.

Hippies wanted a world based on love of humanity and peace. Many believed that wonderful, magical changes were about to take place. They thought these changes would happen as soon as people learned to express their feelings honestly and to behave naturally at all times. Hippies strongly opposed U.S. involvement in the Vietnam War.

Many hippies lived together in small groups, working with one another and sharing possessions. Others refused to be tied down to a fixed job or home. They wandered from place to place seeking part-time work and temporary shelter. Some begged for spare change and lived in the streets or camped in parks or other public lands.

Hippies were sometimes called "flower children" because they gave people flowers to communicate gentleness and love. They let their hair grow long and walked barefoot or in sandals. Hippies attracted public attention by wearing clothing that featured unusual combinations of colors and textures. A large number of hippies used marijuana, LSD, and other drugs. Drug experiences shaped many of their symbols and ideas.

The Beatles, a popular English rock group, helped spread the hippie movement with their song. Hippie favorites included such other rock groups as the Grateful Dead and the Jefferson Airplane, singers Joan Baez and Bob Dylan, poet Allen Ginsberg, and novelist Ken Kesey. Many hippies admired Timothy Leary, a psychologist who preached salvation through the use of drugs.

In time, most hippies realized it was not easy to reform. society by "dropping'out" of it. Some joined more organized political movements to work for specific social causes. Others turned to spirituality or religion. The majority simply left the hippie stage of their lives behind while trying to hold on to at least a few of the ideals that once inspired them.
