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.

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.
