Within hours of appearing on television to announce the end of conscription, President Jacques Chirac moved quickly to prevent any dissent from within the military establishment. Addressing more than 500 military staff officers at the military academy in Paris yesterday, Mr. Chirac said clearly that he "expected" their loyalty in the work of rebuilding France’s national defense.He understood their "legitimate concerns, questions and emotions" at the reforms, but added. "You must understand that there is not and never has been any rigid model for French defense. Military service has been compulsory for less than a century. Realism required that our armed forces should now be professional."The president’s decision to abolish conscription over a period of six years removes a rite of passage for young Frenchmen that has existed since the Revolution, even though obligatory national service only became law in 1905. As recently as 1993, an opinion poll showed that more than 60% of French people said they feared the abolition of conscription could endanger national security. A poll conducted this month, however, showed that 70% of those asked favored ending of practice, and on the streets and in offices yesterday, the response to Mr. Chirac’s announcement was generally positive.Among people who completed their 10-month period of national service in the last few years or were contemplating the prospect, there was almost universal approval, tempered by a sense that something hard to define--mixing with people from other backgrounds, a formative experience, a process that encouraged national or social cohesion--might be lost.Patrick, who spent his year in the French city of Valance assigning and collecting uniforms, and is now a computer manager, said he was in tears for his first week, and hated most of his time. He thought it was "useless" as a form of military training-- "I only fired a rifle twice"--but, in retrospect, useful for learning how to get on with people and instilling patriotism.As many as 25% of those liable for military service in France somehow avoid it--the percentage is probably much greater in the more educated and higher social classes.According to Geoffroy, a 26-year-old reporter, who spent his time in the navy with the information office in central Paris, the injustice is a good reason for abolishing it. People with money or connections, he said, can get well-paid assignments abroad. "It’s not fair: some do it, some don’t."Several expressed support for the idea of a new socially-oriented voluntary service that would be open to both men and women. But the idea seemed less popular among women. At present, women have the option of voluntary service and a small number choose to take it. What worries people who have recently completed their military service about the reform()
A lack of experience that helps build national morale
B. The injustice arising from voluntary military service
C. A shortage of recruit
D. The weakening of national defense
Many theories concerning the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories (21) on the individual suggest that children engage in criminal behavior (22) they were not sufficiently penalized for previous misdeeds or that they have learned criminal behavior through (23) with others. Theories focusing on the role of society suggest that children commit crimes in (24) to their failure to rise above their socioeconomic status, (25) as a rejection of middle-class values. Most theories of juvenile delinquency have focused on children from disadvantaged families, (26) the fact that children from wealthy homes also commit crimes. The latter may commit crimes (27) lack of adequate pa- rental control. All theories, however, are tentative and are (28) to criticism. Changes in the social structure may indirectly (29) juvenile crime rates. For example, changes in the economy that (30) to fewer job opportunities for youth and rising unemployment (31) make gainful employment increasingly difficult to obtain. The resulting discontent may in (32) lead more youths into criminal-behavior. Families have also (33) changes these years. More families consist of one-parent households or two working parents; (34) , children are likely to have less supervision at home (35) was common m the traditional family structure. 26()
A. considering
B. ignoring
C. highlighting
D. discarding
What are the chances that we will encounter some alien form of life, as we explore the galaxy.If the argument about the time scale for the appearance of life on Earth is correct, there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self designing mechanical or biological life forms Why hasn’t the Earth been visied, and even colonized. I discount suggestions that UFOs contain beings from outer space. I think any visits by aliens would be much more obvious, and probably also, much more unpleasant. What is the explanation of why we have not been visited One possibility is that the argument about the appearance of life on Earth is wrong. Maybe the probability of life spontaneously appearing is so low that Earth is the only planet in the galaxy, or in the observable universe, in which it happened. Another possibility is that there was a reasonable probability of forming self-reproducing system, like cells, but most of these forms of life did not evolve intelligence. A third possibility is that there is a reasonable probability for life to form, and to evolve to intelligent beings, in the external transmission phase. But at that point, the system becomes unstable, and the intelligent life destroys itself. This would be a very pessimistic conclusion. I very much hope it isn’t true. I prefer a fourth possibility: there are other forms of intelligent life out there, but we have been overlooked. There used to be a project called SETI, the search for extraterrestrial intelligence. It involved scanning the radio frequencies, to see if we could pick up signals from alien civilizations. I thought this project was worth supporting, though it was cancelled due to a lack of funds. But we should have been wary of answering back, until we have developed a bit further. Meeting a more advanced civilization, at our present stage, might be a bit like the original inhabitants of America meeting Columbus. I don’t think they were better off for it. By comparison, the author considers that
A. a more advanced civilization will destroy us if they visit us at present
B. the original inhabitants of America were better off because of Columbus’ visit
C. being visited by a more advanced civilization will do us good
D. we wouldn’t be better off even though we were visited by the beings from outer space at present
