This has become more difficult than it used to be owing to the extent and complexity of the special knowledge required of various kinds of technicians. Suppose, for example, that you are engaged in research in scientific medicine. The work is difficult and is likely to absorb the whole of your mind. You have no time to consider the effect which your discoveries or inventions may have outside the field of medicine. You succeed (let us say) as

modern medicine has succeeded, in enormously lowering the infant death-rate, not only in Europe and America, but also in Asia and Africa. This has the entirely unintended result of making the food supply inadequate and lowing the standard of life in the parts of the world that have the greatest populations. To take an even more dramatic example, which is in everybody's mind at the present time, you study the makeup of the atom from a disinterested (无利害关系的) desire for knowledge, and by chance place in the hands of a powerful mad man the means of destroying the human race.

Therefore, with every increase of knowledge and skill, wisdom becomes more necessary, for every such increase augments (增强) our capacity for realizing our purposes, and therefore augments our capacity for evil, if our purposes are unwise.

Disagreement arises when people try to decide ______ .

A．how much more wisdom we have now than before

B．what wisdom is and how to develop it

C．if there is a great increase of wisdom in our age

D．whether wisdom can be developed or not

But now the tables have turned. Today Silicon Valley executives are the ones often coming out in suits. No wonder that Fortune 500 executives are dusting off their silk ties and pants. "I would say there is a trend now toward a little more business dress," said Kennedy. "I find myself wearing suits more."

While there isn't a rush toward formal office wear, clothiers and executives say the workplace uniform. is heading that way. In many offices, men are wearing jackets, ties and pants more frequently than a year ago. Top women executives never went as casual as men, so the shift doesn't affect them as dramatically.

"Business casual" took several years to catch on. It started with casual Fridays, evolved to casual summers, then became casual everyday.

Observers mention many factors driving the trend Internet companies helped lead the dress-down movement and other industries followed suit to attract workers. But with the collapse of many dot-corns, the relaxed look is becoming a style. to avoid. Moreover, as the economy stumbles, more people are hunting for jobs or trying to keep the ones they have, and appearance counts.

U.S. President Bush wears a coat and tie in the White House office and expects his staff to dress "professionally," which some say sets a tone for the nation.

"Business casual" was prevalent several years ago because ______

B．shaking hands with clients became popular

C．the country was fighting the conservatives

D．the Internet companies boomed then

【C1】

A．Moreover

B．However

C．Therefore

D．Otherwise

The immune system in our bodies fights the bacteria and viruses which cause disease. There- fore, whether or not we are likely to get various diseases depends on how well our immune system works. Biologists used to think that the immune system was a separate, independent part of our bodies. Recently, however, they have found that our brain can affect our immune system. This discovery indicates that there may be a connection between emotional factors, such as stress or depression, and illness.

Although many doctors in the past suspected a connection between emotional factor and disease, they had no proof. Scientists have only recently discovered how the brain and the immune sys- tem function. Before this, no one could see a link between them. As a result, medical science never seriously considered the idea that psychological factors could cause disease.

Several recent studies showed a connection between stress and illness, for example, researchers went to an American military school to study the students. They found that the sick students there had a lot of academic pressure and wanted to achieve, but they were not very good students. In a similar study, researchers studied a group of student nurses and found that the nurses who developed cold sores were the ones who described themselves as generally unhappy people.

In addition to these results, which support their theory, researchers are also looking for proof that stress can damage the immune system. Researchers studied recently bereaved people, i. e. , people whose loved ones have just died, because they are more likely to become ill or die. By examining the immune system of recently bereaved people, the researchers made an important discovery. They examined some white blood cells which are an important part of the immune system. They were not functioning properly. The fact that they were not working correctly indicates that severe psycho- logical stress, such as a loved one's death, may damage an important part of our immune system.

There is still no positive proof of a connection between the immune system and psychological factors. Researchers also say that the results of the studies on bereaved people could have a different explanation. For example, bereaved people often sleep and eat less than normal, or may drink alcohol or take medication. These factors can also affect the immune system. More research is needed to clearly establish the connection between the immune system and psychological factors.

The study on the military school students indicated that ______.

A．life in the school was very stressful

B．disease could be caused by psychological factors

C．the good students were likely to fall ill

D．stress often made students unhappy

Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world.

Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty.

Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.

Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion.

The markup may be quite high 90 percent of cost or it may be low. Grocery items in a supermarket usually have a low markup, while mink coast have a very high one. High markups, however, do not in themselves guarantee big profits. Profits come from turnover. If an item has a 50 percent markup and does not sell, there is no profit. But if a cereal has an 8 percent markup and sells very well, there are reasonable profits.

While most pricing is based on cost factors, there are some exceptions. Prestige pricing means setting prices artificially high in order to attract select clientele. Such pricing attempts to suggest that the quality or style. of the product is exceptional or that the item cannot be found elsewhere. Stores can use prestige pricing to attract wealthy shoppers.

Leader pricing and bait pricing are the opposites of prestige pricing. Leader pricing means setting low prices on certain items to get people to come into the stores. The products so priced are called loss leaders because little or no profit can be made on them. The profits are made from other products people buy while in the store. Bait pricing, now generally considered illegal, means setting artificially low prices to attract customers. The store, however, has no intention of selling goods at the bait prices. The point is to get people into the store and persuade them of the inferiority of the low-priced item. Then a higher-priced item is presented as a better alternative.

A common retail tactic is odd priced products. For some products of $300, the store will set the price at $295 or $299.95 to give the appearance of a lower price. Automobiles and other high-priced products are usually priced in this manner. For some reason $7995 has more appeal to a potential car customer than $8000.

Bid pricing is a special kind of price setting. It is often used in the awarding of government contracts. Several companies are asked to submit bids on a job, and normally the lowest bidder wins. A school system may want to buy a large number of computers. Several companies are asked to submit prices, and the school district will decide on the best bid based as well on considerations of quality and service.

What is the base of selling price？

A．the cost of production

B．a percentage of total cost

C．the cost of transportation

D．the cost of storage.
