单选题 Questions13-16 are based on the passage you have just heard.

单选题Perhaps all criminals should carry cards which read "Fragile, Handle with Care". It will never do, to go around referring to criminals as violent persons. You must refer to them politely as "social misfits". The professional killer who wouldn"t think twice about battering some harmless old lady to death in order to rob her of her small life saving must never be given a dose of his own medicine. He is in need of "hospital treatment". According to his misguided defenders, society is to blame. A wicked society breeds evil or so the argument goes. When you listen to this kind of talk, it makes you wonder why we aren"t all criminals. We have done away with the absurdly harsh laws of the nineteenth century and this is only right. But surely enough is enough. The most senseless piece of criminal legislation in many countries such as Britain has been the suspension of capital punishment. The violent criminal has become a kind of hero figure in our time. He is glorified on the screen; he is pursued by the press and paid vast sums of money for his "memoirs". Newspapers which specialize in crime reporting enjoy enormous circulations and the publisher of trashy cops and robber stories or "number mysteries" have never had it so good. When you read about the achievements of the great train robbers, it makes you wonder whether you are reading about some glorious resistance movement. The hardened criminal is embraced and cosseted by the sociologists on the one hand and adored as a hero by the masses on the other. It"s no wonder he is a privileged person who expects and receives VIP treatment wherever he goes. Capital punishment used to be a major deterrent. It made the violent robber think twice before pulling the trigger. It prevented unarmed policemen from being killed while pursuing their duty by killers armed with automatic weapons. Above all, it protected the most vulnerable members of society, young children, from brutal violence. It"s frightening to think that the criminal can literally get away with murder. We all know that "life sentence" does not mean what it says. After ten years or so of good conduct, the most desperate wicked person can return to society where he will live very comfortably on the proceeds of his crime, or he will go on committing offences until he is caught again. People are always willing to hold liberal views at the expense of others. It"s always fashionable to pose as the defender of the underdog so long as you remain unaffected. Did the defenders of crime consult the victims before they suspended capital punishment in their desire for fair play? Hardly, you know, they couldn"t, because all the victims were dead.

单选题 Humans use water for three basic purposes: agriculture, industry, and domestic and municipal use (water for drinking, cooking, cleaning, and so forth). And the amount of water 27 to each person decreases as the population grows, 28 the possibility of water shortages. Water shortages will not come all at once in every part of the world, just as the world's population is 29 distributed by region, so is the annual 30 of renewable water. Rainfall and snowfall are 31 by uneven weather patterns and landscape, and as a result, some areas of the world get more precipitation than others. This leads the uneven 32 of water all over the world. Natural water scarcity has prompted many nations to try to increase their water supplies by building dams to catch water that otherwise would escape to the sea, or by sinking more and deeper wells. But these efforts can have 33 side effects that can contribute to water scarcity. Instead of building dams, some countries choose to increase their 34 to groundwater. But this practice increases the risk of over pumping aquifers (蓄水层). Pollution also affects the water supply, reducing the available water by making it toxic or otherwise 35 for human use. Water shortages could also lead to international conflicts as countries 36 for limited water resources. Political tensions over water often appear when different nations lay claim to the same river, lake, or aquifer. According to the UN, more than 300 river basins and aquifers worldwide cross national boundaries are creating the potential for conflicts. A. access B. positively C. deliberately D. compete E. negative F. distribution G. available H. determined I. unevenly J. unfit K. starved L. raising M. approach N. arising O. supply

单选题It is true that the group interactions have both positive and negative sides. When we 22 , conflict cannot be gotten rid of. Having open discussion of conflict doesn't always bring advantages. It may come with negative effects, reducing 23 and lowering job satisfaction. During the work we found that the conflict can 24 task conflicts and relationship conflicts. These two kinds of conflicts are different in that the first one occurs when there are disagreements in completing the tasks; however, relationship conflict is initiated by 25 interpersonal relationships and is linked with friction and tension. Relationship conflict is considered to 26 performance because it leads to negative emotions, destructive behaviors and distraction. Some researches show that task conflicts can improve the performance as it 27 evaluation of assumptions, open expression. Therefore generating better solutions becomes easy. Conflicts and relationship negatively have something to do with individuals' satisfaction. The members want to stay in the group, favoring of other group members. The regular patterns are like this: When we are doing very 28 tasks, it is not good to group functioning, as many disagreements come out. On the contrary, when the group 29 non-routine tasks, disagreements won't have detrimental (不利的) effects, and 30 , disagreements are beneficial to the tasks. While discussion of conflict is not always advantageous and norms are linked with an increase in the number and intensity of relationship conflicts, they did not increase members' ability to deal with the conflicts 31 .

单选题 For thousands of years, people thought of glass as something beautiful to look at. Only recently have they come to think of it as something to look through. Stores display their goods in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary objects. Until the Second World War, most of the glass used for optical instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. As a result, new kinds of glasses were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of these new glasses are very strong and can resist many kinds of shocks. Legend has it that a very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and silver, malting his treasure worthless. Therefore, he had the glassmaker killed, and the secret was not discovered again for hundreds of years. In the present century, safety glass was invented for use in modern cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter and injure people. Some glass of this type is strong enough to resist bullets. Although in recent years plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component parts are inexpensive and can be found all over the world.
