单选题Change—or the ability to adapt oneself to a changing environment—is essential to evolution. The farmer whose land is required for housing or industry must adapt himself: He can move to another place and master the problems peculiar to it; he can change his occupation, perhaps after a period of training; or he can starve to death. A nation which can not adapt its trade or defense requirements to meet world conditions faces economic or military disaster. Nothing is fixed and permanently stable. There must be movement forward, which is progress of a sort, or movement backwards, which is decay and deterioration. In this context, tradition can be a force for good or for evil. As long as it offers a guide(without insisting that its path is the only one), it helps the ignorant and the uninformed to take a step forward, and thereby, to adapt themselves to changed circumstances. Tradition, or custom, can guide the hunter as effectively as it can influence the nervous hostess. But if we make an idol(偶像、崇拜)of tradition, it ceases to become a guide and becomes an obstacle lying across the path of change and progress. If we insist on trying to plot the future by the past, we clearly handicap ourselves and invite failure. The better course is to adopt the help which tradition can give but, realizing that it necessarily has its roots in the past, to be well aware of its limitations in a changing world.

单选题The market for manufactured goods is what economists call "imperfect," because each company has its own style, its own reputation, and its own locations; and all of the arts of advertisement and salesmanship are devoted to making it even more imperfect by attracting buyers to particular brand names. Even small businesses that depend upon outside channels of retail distribution may have the final say in what prices they will charge, and great corporations can differentiate their goods in order to create demand of them. In this type of market, supply normally is very elastic--that is responsive to demand--in the short run. Stocks or inventories are held at some point in the chain of distribution; while stocks are running down or building up, there is time to change the level of production, and once a price has been set, it is rarely altered in response to moderate changes in demand. Even in a deep slump, defensive rings may be formed to prevent price cutting. In the long run, as well as in the short, supply is responsive to demand in the market for manufactures. It is easier to change the composition of a firm's output than it is to change the production of a mine or a plantation. And when changes in demand are not too rapid, gross profits from one plant can be siphoned off and invested in something quite different. When business is good, moreover, there is continual new investment so that productive capacity is adapted to meeting changing requirements. Workers themselves may not even be aware of changes in the final commodities to which their work contributes, and the level of wages for any grade of factory labour is very little affected by the fortunes of a particular market.

Mark your answers on ANSWER SHEET 1. {{B}}Text 1{{/B}} A child may lean against a doorpost with his or her arms folded. To the onlooker, it may look like a benign posture—however, there may be a victimized child who understands that this is the bully's "shorthand" code of conveying the message: "Hand me your lunch as you walk by me, or else." Bullying may be expressed in many forms. Boys are generally targeted more than girls. Boys tend to use physical aggression when they bully .by hitting, kicking, and fighting. Girls, on the other hand, more often use {{U}}exclusionary{{/U}} techniques to bully—a form of aggression often referred to as relational aggression. Girls often start rumors, form cliques to keep certain people out, and ignore other children in attempts to show dominance over another child. Many children who are victimized fit into one of two types: the passive victim, and the provocative victim. While people often feel bad about passive victims, provocative victims often elicit less compassion from others. Sometimes it appears that the provocative victim has "brought on" his or her own fate—but does any child deserve to be the target of repeated physical or verbal aggression? Why might so-called provocative victims actively participate in being the target of bullying: For example, are their provocative gestures simply a clumsy way of attempting to interact with others? One feels compassion for the inhibited child because he is reserved; a social misfortune in our society, but an aggressive child is given none of this. The dynamics of the bully/victim relationship need to be understood in a larger context (Pepler, Craig & O'Connell, 1999). It is not only the bully and the victim that is involved in a system of interaction: The bullying context includes multiple levels of the child's social environment. The bully may enlist the help of "henchmen" (those who assist the bully, but often do not have the initiative or leadership to initiate bullying). Also, bystanders (whether actively encouraging the bullying act or passively standing by) play a role in maintaining the pattern of bullying. Even the students who habitually flee the site of a bullying act play a role in maintaining the bully/victim interaction. In handling the situation, it is important not to focus only on the one or two students that are directly involved, but on the playground and school as a whole. Studies have shown that in order to break down the stability of peer bullying you must initiate change on many levels: Not only in teaching the bullied child how to assert himself or herself and to deflect attacks, but also to raise awareness about the problem of bullying and encourage the school community at large to take a united stance against bullying.

单选题Many countries have a tradition of inviting foreigners to rule them. The English called in William of Orange in 1688, and, depending on your interpretation of history, William of Normandy in 1066. Both did rather a good job. Returning the compliment, Albania asked a well-bred Englishman called Aubgrey Herbert to be their king in the 1920s. He refused—and they ended up with several coves called Zog. America, the country of immigrants, has no truck with imported foreign talent. Article two of the Constitution says that "no person except a natural-born citizen... shall be eligible to the office of the president". This is now being challenged by a particularly irresistible immigrant: Arnold Schwarzenegger. Barely a year has passed since the erstwhile cyborg swept to victory in California's recall election, yet there is already an Amend-for-Arnold campaign collecting signatures to let the Austrian-born governor have a goat the White House. George Bush senior has weighed in on his behalf. There are several "Arnold amendments" in Congress: one allows foreigners who have been naturalized citizens for 20 years to become president. (The Austrian became American in 1983.) It is easy to dismiss the hoopla as another regrettable example of loopy celebrity politics. Mr. Schwarzenegger has made a decent start as governor, but he has done little, as yet, to change the structure of his dysfunctional state. Indeed, even if the law were changed, he could well be elbowed aside by another incomer, this time from Canada: the Democratic governor of Michigan, Jennifer Granholm, who appears to have fewer skeletons in her closet than the hedonistic actor. Moreover, changing the American constitution is no doddle. It has happened only 17 times since 1791 (when the first ten amendments were codified as the bill of rights). To change the constitution, an amendment has to be approved by two-thirds of both houses of Congress, and then to be ratified by three-quarters of the 50 states. The Arnold amendment is hardly in the same category as abolishing slavery or giving women the vote. And, as some wags point out, Austrian imports have a pretty dodgy record of running military superpowers.
