Every time you try to answer a question that asks why, you engage in the process of causal analysis--you attempt to determine a cause or series of causes for a particular effect. When you try to answer a question that what if, you attempt to determine what effect will result from a particular cause. You will have frequent opportunity to use cause- and-effect analysis in the writing that you will do in college. For example, in history you might be asked to determine the causes of the Seven Day War between Egypt and Israel. In political science you might be asked to determine the reasons why Ronald Reagan won the 1984 Presidential election. And in sociology you might be asked to predict the effect that changes in Social Security legislation would have on senior citizens.
22. Determining causes and effects is usually thought-provoking and quite complex. One reason for this is that there are two types of causes: immediate causes, which are readily apparent because they are closest to the effect, and ultimate cause, which, being somewhat removed, are not so apparent and perhaps even hidden. Furthermore, ultimate causes may bring about effects which themselves become immediate causes, this creating a causal chain. For example, consider the following causal chain. Sally, a computer salesperson, prepared extensively for a meeting with an important client (ultimate cause), impressed the client (immediate cause), and made a very large sale (effect). The chain did not stop there: The large sale cause her to be promoted by her employer (effect).
A second reason why causal analysis can be so complex is that an effect may have any number of possible or actual causes, and a cause may have any number of possible or actual effects. 23. An upset stomach may be caused by eating spoiled food, but it may also be caused by overeating, flu, allergy, nervousness, pregnancy, or any combination of factors. Similarly, the high cost of electricity may have multiple effects: higher profits for utility companies, fewer sales of electrical appliances, higher prices for other products, and the development of alternative sources of energy. Sound reasoning and logic are central to any causal analysis. Writers of believable causal analysis examine their material objectively and develop their essays carefully. They are convinced by their own examination of the material, but are not afraid to admit other possible causes and effects.
Because people are accustomed to thinking of causes with their effects, they sometimes commit an error in logic known as the "after this, therefore because of this" fallacy. 24. This fallacy leads people to believe that because one event occurred after another event, the first event somehow caused the second. That is, they sometimes make causal connection that are not proved. For example, if students began to perform. better after a free breakfast program was instituted at their school, one could not assume that the improvement was caused by the breakfast program. There could of course be any number of other causes for this effect, and a responsible writer on the subject would analyze and consider them all before suggesting the cause.

A series of experiments were carried out by B. Lat...
A series of experiments were carried out by B. Latane and J. Darley. They studied the reaction of bystanders to emergency situations. Since car accidents, drownings, fires, attempted suicide, and the like arouse feelings of fear and morbid interest, these situations attract large numbers of people who stand fascinated watching the event. Yet, it is a strange aspect of crowd behavior. that often nothing is done to help the victim.
【71】Journalists writing of such events often claimed that this kind of behavior. is due to apathy, indifference, or lack of concern. To account for any bystander's decision to act or not to act, the authors of the paper ask us to consider the basic characteristics of an emergency situation.
Emergencies involve threat or harm certainly to the victim and possibly to those who try to help him (or her). The events are highly unusual, different from the normal course of life and also from each other.【72】Since little secondhand wisdom on the subject is available, it is difficult to cope with a genuine emergency by relying on such worn-out clichés as "Women and children first" or "Send for the police."
The authors tell us that it is perhaps surprising that anyone should intervene at all.【73】
Latane and Darley were interested, therefore, in trying to isolate the factors that make a person decide to act. It seemed to them that an individual is more likely to take action when he or she is alone than when part of a group. Latane and Darley theorized that when only one bystander is present, he or-she must judge the situation alone and decide whether to act or not. Only the bystander is responsible for the decision. The presence of other people, however, affects a person's assessment of the costs and rewards of intervention.【74】
The results of the experiments confirmed the theory. They showed that the immediate social environment is more important in determining a person's reaction to an emergency than are such vague cultural or personality concepts as "apathy" or "indifference." They also help to explain why the failure to intervene seems more common in large cities than in rural areas. In large cities, the members of the crowd that gathers do not take action because they do not feel individually responsible. They may be concerned, but they watch one another, uncertain of how to act, knowing that responsibility is shared. In rural areas, however, witnesses to an emergency are likely to be alone. They must take all the responsibility for their actions and are not made embarrassed or unsure by the presence of others.【75】
A. Thus, people have little experience with handling them.
B. They are, therefore, more likely to come to the aid of the victim.
C. The police asked some of the bystanders about the accident.
D. The investigators had noted this phenomenon and asked themselves why in most cases bystanders do not act.
E. This is because when there is a group, responsibility is diffused over all the members.
F. But people do sometimes intervene.

Soldiers and other military people wear uniforms with various other symbols to indicate their status.But in the business world everyone wears more or less similar suits，and you cannot tell at a glance who ranks higher or lower than another.So how do people in the business world show their superiority？ An attempt to study this was made by two researchers using a series of silent films.They had two actors play the parts of an executive(经理)and a visitor，and switch roles each time.The scene had one man at his desk playing the part of an executive，while the other，playing the part of a visitor，knocks at the door，opens it and approaches the desk to discuss some business matter.
The audience watching the films was asked to rate the executive and the visitor in terms of status.A certain set of rules about status began to emerge from the ratings.The visitor showed the least amount of status when he stopped just inside the door to talk across the room to the seated man.He was considered to have more status when he walked halfway up to the desk，and he had the most status when he walked directly up to the desk and stood right in front Of the seated executive.
Another thing that affected the status of the visitor in the eyes of the observers was the time between knocking and entering.For the seated executive，his status was also affected by the time between hearing the knock and answering.The quicker the visitor entered the room，the more status he had.The longer the executive took to answer，the more status he had.
11.The experiment designed by the two researchers aimed at finding out().
A、how business is conducted by an executive and a visitor
