单选题"Lucky" Lord Lucan--Alive or Dead On 8th November 1974 Lord Lucan, a British aristocrat (贵族) , vanished. The day before, his children"s nanny (保姆) had been brutally murdered and his wife had been attacked too. To this day the British public are still interested in the murder case because Lucan has never been found. Now, over 30 years later, the police have reopened the case, hoping that new DNA techniques will help solve this murder mystery. People suspected that "Lucky", as he was called by friends, wanted to kill his wife he no longer lived with. They say that Lucan entered his old house and in the dark, killed the nanny by mistake. His estranged wife heard noises, came downstairs and was also attacked, but managed to escape. Seven months after the murder, a jury concluded that Lucan had killed the nanny. What happened next is unclear, but there are several theories which fall into one of three categories: he may have killed himself, he could have escaped or he might have been killed. It appears that the night after the murder, "Lucky" borrowed a car and drove it. Lucan"s friend Aspinall said in an interview that he thought Lucan had committed suicide by sinking his boat in the English Channel. Another version of events says that "Lucky" left the blood-soaked car on the coast and took a ferry to France. He was met there by someone who drove him to safety in another country. However, after a time, his rescuers became worried that they would become involved in the murder too and so Lucan was killed. A further fascinating theory was made in the book Dead Lucky by Duncan MacLaughlin, a former detective. He believes that Lucan travelled to Goa, India, where he assumed the identity of a Mr. Barry Haplin. Lucan then lived in Goa till his death in I996. In the end the claim turned out to be a case of mistaken identity. The man who died in 1996 was really Haplin, an ex-schoolteacher turned hippy. So what is the truth about "Lucky"? DNA testing has solved many murder cases, but who knows if it can close the book on this one.

单选题{{B}}第二篇{{/B}} {{B}} System of Criminal Trial{{/B}} How efficient is our system of criminal trial? Does it really do the basic job we ask of it— convicting the guilty and acquitting the innocent? It is often said that the British trail system is more like a game than a serious attempt to do justice. The lawyers on each side are so en- grossed in playing hard to win, challenging each other and the judge on technical points, that the object of finding out the truth is almost forgotten. All the effort is concentrated on the big day, on the dramatic cross examination of the key witnesses in front of the jury. Critics like to compare our "adversarial" system (resembling two adversaries engaged in a contest) with the continental "inquisitorial" system, under which the judge plays a more important inquiring role. In early times, in the Middle Ages, the systems of trial across Europe were similar. At that time trial by "ordeal"—especially a religious event—was the main way of testing guilt or innocence. When this way eventually abandoned the two systems parted company. On the continent church-trained legal officials took over the function of both prosecuting and judging, while in England these were largely left to lay people, the Justice of the Peace and this meant that all the evidence had to be put to them orally, this historical accident dominates procedure even today, with all evidence being given in open court by word of mouth on the crucial day. On the other hand, in France for instance, all the evidence is written before the trial under supervision by an investigating judge. This exhaustive pretrial looks very undramatic; much of it is just a public checking of the written records already gathered. The Americans adopted the British system lock, stock and barrel and enshrined it in their constitution. But, while the basic features of our systems are common, there are now significant differences in the way serious cases are handled. First, because the U. S.A. has virtually no contempt of court laws to prevent pretrial publicity in the newspaper and on television, Americans lawyers are allowed to question jurors about knowledge and beliefs. In Britain this is virtually never allowed, and a random selection of jurors who are presumed not to be prejudiced are empanelled. Secondly, there is no separate profession of barrister in the United States, and both prosecution and defense lawyers who are to present cases in court prepare them themselves. They go out and visit the scene, track down and interview witnesses, and familiarize themselves personally with the background. In Britain it is the solicitor who prepares the case, and the barrister who appears in court is not even slowed to meet witness beforehand. British barristers also alternate doing both prosecution and defense work. Being kept distant from the preparation and regularly appearing for both sides, barristers are said to avoid becoming too personally involved, and can approach cases more dispassionately. American lawyers, however, often know their cases better. Reformers rightly want to learn from other countries' mistakes and successes. But what is clear is that justice systems, largely because they are the result of long historical growth, are peculiarly difficult to adapt piecemeal.

单选题{{B}}第一篇{{/B}} {{B}}"Salty" Rice Plant Boosts Harvests{{/B}} British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University's School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 100 hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants' growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.

单选题{{B}}第二篇{{/B}} {{B}} The Deer's Death{{/B}} He ran close, and again stood still, stopped by a new fear. Around him the grass was whispering and alive. He looked wildly about, then down. The ground was black with ants, great energetic ants that took no notice of him, but hurried towards the fighting shape. And as he drew in his breath and pity and terror seized him, the beast fell and the screaming stopped. Now he could hear nothing but a bird singing, and the sound of the rustling (沙沙声) whispering ants. He peered over at the blackness that twitched with the jerking(抽搐) nerves. It grew quieter. There were small twitches from the mass that still looked vaguely like the shape of a small animal. It came into his mind that he could shoot it and end its pain; and he raised the gun. Then he lowered it again. The deer could no longer feel; its fighting was a mechanical protest of the nerves. But it was not that which made him put down the gun. It was a swelling feeling of rage and misery and protest that expressed itself in the thought: if I had not come it would have died like this, so why should I interfere? All over the bush things like this happen; they happen all the time; this is how life goes on, by living things dying painfully. I cannot stop it. He was glad that the deer was unconscious and had gone past suffering so that he did not have to make a decision to kill it. At his feet, now, were ants tricking back with pink fragments in their mouths and there was a fresh acid smell in his nose. He sternly controlled the uselessly convulsing(痉挛的) muscles of his empty stomach, and reminded himself: the ants must eat, too. The shape had grown small. Now it looked like nothing to be recognized. He saw the blackness thin, and bits of white showed through, shining in the sun—yes, there was the sun just up. Then the boy looked at those insects. A few were standing and gazing up at him with small glittering eyes. "Go away!" he said to the ants coldly. "I am not for you—not just yet, at any rate." He bent over the bones and touched the sockets(孔) in the skull: that was where the eyes were, he thought suspiciously, remembering the liquid eyes of a deer. That morning, perhaps an hour ago, this small creature had been stepping proud and free through the bush even as he himself had done. Proudly stepping the earth, it had smelt the cold morning air. Walking like kings, it had moved freely through this bush, where each blade of grass grew for it alone, and where the river ran pure sparkling water for it to drink. And then—what had happened? Such a sure swift footed thing could surely not be trapped by a swarm of ants?

单选题One Good Reason to Let Smallpox Live It"s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia? If smallpox had truly gone from the planet, what point was there in keeping these reserves? 1 reality, of course, it was naive to 2 that everyone would let 3 of such a potent potential weapon. Undoubtedly several nations still have 4 vials. 5 the last "official" stocks of live virus bred mistrust of the US and Russia, 6 no obvious gain.
