单选题The two claws of the mature American lobster are decidedly different from each other. The crusher claw is short and stout; the cutter claw is long and slender. Such bilateral asymmetry, in which the fight side of the body is, in all other respects, a mirror image of the left side, is not unlike handedness in humans. But where the majority of humans are righthanded, in lobsters the crasher claw appears with equal probability on either the right side or left side of the body. Bilateral asymmetry of the claws comes about gradually. In the juvenile fourth and fifth stages of development, the paired claws are symmetrical and cutter like. Asymmetry begins to appear in the juvenile sixth stage of development, and the paired claws further diverge toward welldefined cutter and crusher claws during succeeding stages. An intriguing aspect of this development was discovered by Victor Emmer. He found that if one of the paired claws is removed during the fourth or fifth stage, the intact claw invariably becomes a crusher, while the regenerated claw becomes a cutter. Removal of a claw during a later juvenile stage or during adulthood, when asymmetry is present, does not alter the asymmetry; the intact and regenerate claws retain their original structures. These observations indicate that the conditions that trigger differentiation must operate in a random manner when the paired claws are intact, but in a nonrandom manner when one of the claws is lost. One possible explanation is that differential use of the claws determines their asymmetry. Perhaps the claw that is used more becomes the crusher. This would explain why, when one of the claws is missing during the fourth or fifth stage, the intact claw always becomes a crusher. With two intact claws, initial use of one claw might prompt the animal to use it more than the other throughout the juvenile fourth and fifth stages, causing it to become a crusher. To test this hypothesis, researchers raised lobsters in the juvenile fourth and fifth stages of development in a laboratory environment in which the lobsters could manipulate oyster chips. (Not coincidentally, at this stage of development lobsters typically change from a habitat where they drift passively, to the ocean floor where they have the opportunity to be more active by borrowing in the substrate. ) Under these conditions, the lobsters developed asymmetric claws, half with crusher claws on the left, and half with crusher claws on the right. In contrast, when juvenile lobsters were reared in a smooth tank without the oyster chips, the majority developed two cutter claws. This unusual configuration of symmetrical cutter claws did not change when the lobsters were subsequently placed in a manipulable environment or when they lost and regenerated one or both claws.

单选题Where is the second centre of Hollywood film making in Europe. after London*. Paris. or perhaps Berlin? Try Prague. Last year, Hollywood spent over $200m on shooting movies, commercials and pop videos in the Czech capital. This year. all the big studios will be in town. MGM has "Hart's War" starring Bruce Willis; Disney is shooting "Black Sheep" with Anthony Hopkins; and Fox has just finished filming "From Hell", a Jack the Ripper saga starring Johnny Depp. Praguers take Tinseltown in their stride. Old ladies looked only slightly confused last month when the cobbled streets of Mala Strana, Prague's old quarter, were cleared of real snow and sprayed with a more cinematically pleasing chemical alternative for Universal's "Bourne Identity", a $50m thriller starring Matt Damon. The film's producer, Pat Crowley, reckons a day filming in Prague costs him $100.000, against $250,000 in Paris. Czech crews, he says, are professional, English-speaking and numerous. They are also a bargain—40% cheaper than similar crews in London or Los Angeles, points out Matthew Stillman. the British boss of Stillking, a Prague-based production firm. Mr. Stillman founded Stillking in 1993 after arriving in Prague with $500 and a typewriter. Today, Hollywood producers come to the company for crews, catering, lights and much more. It claims to have about half of the local film-production business and this year hopes for revenues of over $50m. The biggest draw to Prague, however, is Barrandov—one of the largest film studios in Europe, with 11 sound-stages, onsite photo labs and top-notch technicians. It was founded during Czechoslovakia's pre-war first republic by Milos Havel, an uncle of the present Czech president, Vaclav Havel. The Nazis expanded it as a production centre for propaganda flicks—the sound-stages are courtesy of Joseph Goebbels. Then came the Communists with their own propaganda and, admittedly, a few impressive homegrown directors such as Milos Forman, who began Hollywood's march to Prague by filming "Amadeus" there. But it is partly thanks to Barrandov that Prague remains some way behind London as a film centre. The studio has suffered from doubtful management and is already stretched to capacity ("You can't even get an office there," moans one producer). Its present owner, a local steel company, is keen to sell but talks with a Canadian institution have been thorny, not least because the Czech government holds a golden share. Should the Canadian deal fall through, Stillking says it would consider a bid of its own.

单选题Do you ever automatically say "God bless you" when someone sneezes? Did you ever cross your fingers when making a wish? Most people who do these things never think about why they do them. They just do them. But there is a reason. Both acts are meant to insure good luck. They are little superstitions that have come down to us from an earlier time, when everybody believed in good and evil spirits. And even in our modern world, when men are traveling to the moon, we are still practicing some of these ancient habits in our daily lives. In ancient times, men believed that the soul lived in the head. Every time someone sneezed, he was risking the danger of dislodging that soul and blowing it out the nose into the outside world. So, as insurance against a lost soul, people would say "God bless you" to be sure that God would catch the soul and return it to its rightful owner. Some people today toss a bit of salt over their left shoulder if they happen to spill any at the dinner table. This practice once had a serious purpose. In an earlier time, men believed that evil spirits always stood on their left side and good sprits on the right. So any time they spilled some of the precious stuff, they would throw a bit of it over their left shoulder to keep away the evil spirits. Since the evil spirits stood on the left, and the good spirits on the right, the right side was considered the lucky side of the body. Putting your best foot forward meant starting out on the lucky side, with your right foot first. That was a guarantee of good luck at whatever you were about to do. We still speak of "putting your best foot forward," although we don't always start walking with the right foot.

单选题{{B}}Passage Four{{/B}} Real policemen, both Britain and the United States, hardly recognize any resemblance between their lives and what they see on TV - if they ever get home in time. There are similarities, of course, but the cops don't think much of them. The first difference is that a policeman's real life revolves round the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to scantily clad ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilty-or not-of stupid, petty crimes. Most television crime drama is about finding the criminal; as soon as he's arrested, the story is over. In real life, finding criminals is seldom much of a problem: Except in very serious cases like murders and terrorist attacks-where failure to produce results reflects on the standing of the police-little effort is spent on searching. The police have an elaborate machinery which eventually shows up most wanted men. Having made an arrest, a detective really starts to work. He has to prove his case in court and to do that he often has to gather a lot of different evidence. Much of this has to be given by people who don't want to get involved in a court case. So as well as being overworked, a detective has to be out at all hours of the day and night interviewing his witnesses and persuading them, usually against their own best interests, to help him. A third big difference between the drama detective and the real one is the unpleasant moral twilight in which the real one lives. Detectives are subject to two opposing pressures: first as members of a police force they always have to behave with absolute legality, secondly, as expensive public servants they have to get results They can hardly ever do both. Most of the time some of them have to break the rules in small ways. If the detective has to deceive the world, the world often deceives him. Hardly anyone he meets tells him the truth. And this separation the detective feels between himself and the rest of the world is deepened by the simple mindedness-as he sees it-of citizens, social workers, doctors, law makers, and judges, who, instead of stamping out crime punish the criminals less severely in the hope that this will make them reform. The result, detectives feel, is that nine tenths of their work is recatching people who should have stayed behind bars. This makes them rather cynical.
