单选题Where there is no law, there can be no crimes. The first question, therefore, is: Are there any international crimes? And the answer is No--for several reasons. In the first place, there is no body of international law explaining what is meant by international crimes. Secondly, national laws are only useful within a particular country, However, efforts have been made to have certain actions internationally recognized as crimes. It has been accepted by the countries which have joined Interpol ( 国际刑警组织) that any crime which has an international effect should be considered an international crime. This can be shown clearly by a recent case in India. An Englishman, pretending that he was a reporter of a leading British daily, canto to India. He showed great interest in the jewelry markets of Delhi and later bought a very expensive gold watch and a couple of gold rings. One shopkeeper, eager to sell his jewellery, willingly made a deal with him for 22,000 rupees; the only difficulty was the way of payment. The foreigner gave two cheques drawn on the Bangkok branch of the Bank of America, which the shopkeeper accepted, admiring the customer's wealth. The foreigner had, however, given worthless cheques and lost no time in leaving the country with his precious possessions. The cheques were refused by the bank. The shopkeeper went to the Indian office of Interpol. Interpol. Delhi, on request from the police, quickly got in touch with Interpol, London, and learnt that the international criminal had been caught there for crimes of stealing as well as for giving valueless cheques. It came to light that he had been related to 27 similar crimes, Interpol asked Britain to send him to Delhi and he was then put into prison and fined 2,000 rupees.

单选题More than 6,000 children were expulsed (开除) from U.S. schools last year for bringing guns and bombs to school, the U.S. Department of Education said on May 8. The department gave a report to the expulsions as saying handguns accounted for 58 percent of the 6,093 expulsions in 2003-2004, against 7 percent for rifles(步枪) or shotguns and 35 percent for other types of firearms. "The report is a clear sign that our nation's public schools are cracking down(严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be strong-minded about keeping guns out of our schools and do everything to keep our children safe. " In March 2004, an 11 years old boy and 13 years old boy using hand-guns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven were wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky. Most of the expulsions, 56 percent, were from high schools, which have .students from about age 13. 34 percent were from junior high schools and 9 percent were from elementary schools, the report said.

单选题Now that man has actually landed on the surface of the moon, he has learned many new things about it. But one thing man knew before he ever reached the moon was that there was no life on it. There is no atmosphere on the moon. The lack of air means that the moon is not protected from any of the sun's rays. The sun sends out heat and light radiation (辐射). Life on the earth depends on heat and light. But the sun also sends out dangerous kinds of radiation. The earth's atmosphere protects us from most of them. On the moon, however, there is no atmosphere to stop the radiation. All the sun's rays beat down on the surface of the moon. Because there is no atmosphere, the moon's surface is either extremely hot or extremely cold. As the moon circles around the earth, the side of it that is lighted up by the sun becomes very hot. The temperature there reaches more than 300 degrees Fahrenheit (华氏温度). This is hotter than boiling water. The hot lunar day lasts two weeks. It is followed by a night that is also two weeks long. At night the temperature drops to about 260 degrees below zero Fahrenheit. "This is more than twice as cold as temperatures reached at the earth's South Pole. Under these conditions, no form of life that we know of here on the earth could exist on the moon.

单选题An office is the "Brain" of a business. In an office, figures (数字), lists and information are collected and arranged to tell the managers or heads of the business what has happened and what is happening in their shops or factories. Information comes into an office in all sorts of ways, but the main items of information come in regularly. It is part of the job of the clerks to collect, sort out and classify that information and to put it into such a form that it is easily interpreted (说明) and understood. Offices not only collect information but also classify it. This work of collection is common in an office from the sorting of mail every morning to the accountant's (会计) work in finding out the final figure for the year's profit. Classification always requires the arrangement of the same kind of information in lists or columns. For this work, as in all office work, correctness, accuracy and speed are necessary. These are the essentials of classifying. There is no value, however, in collecting figures which mean nothing. Figures are guides which should help managers make decisions. The interpretation of figures should tell where success or failure lies, where profit comes and where losses occur. On the basis of this information, a choice is made and a series of such choices may make a policy. A firm which has three factories may find, for instance, from its figures, that one factory is losing money. Then the firm is faced with these choices: a change of manager, a cut in production, an increase in production, or closure (关闭) of the factory. Whichever one of these decisions is taken becomes the policy. A policy means a plan of action. It is clear that a decision leading to a policy can only be as good as the information on which it is based. Consequently there is a constant search for more and more exact information on the part of the management, which wants to have all the necessary facts before it can make the best decision.

单选题Urban life has always involved a balancing of opportunities and rewards against dangers and stress; its motivating force is, in the broadest sense, money. The presence of huge numbers of people inevitably involves more conflict, more traveling, the overloading of public services and exposure to those deviants and criminals who are drawn to the rich pickings of great cities. As a defense against these developments, city dwellers tend to use various strategies to try and reduce the pressures upon themselves; contacts with other people are generally made brief and impersonal; doors are kept locked and so on. There are other strategies, too, which are positively harmful to the individuals, for example, reducing awareness through drags or alcohol. Furthermore, all these defensive forms of behavior are harmful to society in general. Lack of informal social contact and indifference to the misfortunes of others, are amongst the major causes of urban crime. Present day architecture and planning have enormously worsened the human problems of urban life. People have been forced to leave their familiar homes, usually to be rehoused in tower blocks which are inconvenient. This destruction of established social structures is the worst possible approach to the difficulties of living in a town or city. Instead, every effort should be made to conserve the human scale of the environment, and to retain familiar landmarks.
