根据下列材料请回答 26～30 题：BToday there are policemen everywhere, but in 1700, London had no policemen at all. A few old men used to protect the city streets at night and they were not paid.About 300 years ago, London was starting to get bigger and more and more people began to live there. The city was very dirty and many people were poor. There were so many thieves who stole money in the streets that people stayed in their homes as much as possible.In 1750, Henry Fielding started to pay a group of people to stop thieves. They were like policemen and were called "Bow Street Runners" because they worked near Bow Street.Fifty years later, there were 120 "Bow Street Runners", but London had become very big and needed more policemen. So in 1829, the first Metropolitan (or London)Police Force was started with 3,000 officers. Most of the men worked on foot, but a few rode horses. Until 1920 all the police in London were men.Today. the London police are quite well paid and for the few police officers who still ride horses, the pay is even better than for the others.第 26 题 In 1700, the men who protected the streets were paid __________.A． a fewB． nothingC． a littleD． a lot
So many directors_________ , the board meeting had to be put off till next Monday.A． were absentB． being absentC． been absentD． had been absent
Passage FiveA young girl and a man were recently found murdered in a parked car in a Boston suburb. The police found no clue (线索) in the car. Then they found a witness who had seen a car pass by the murdered couple's car. He said it was a 1950 or 1951 Chevrolet (雪佛莱牌汽车).Ordinarily, searching through the files for owners of elderly Chevies would have been an impossibly difficult task because there were two and a half million such cars. In this case, however, the police had a powerful tool--the computer.The Boston Registry of Motor Vehicles programmed its computer to screen all 1950 and 1951 Chevrolets within a fifteen-mile radius (半径) of the suburb--the area in which the police believed the murderer was most likely to be found. Within minutes, the computer uncovered one thousand of the wanted cars. A few hours of careful hand screening turned up a 1950 Chevrolet owner who lived close to the scene of the crime and who had received many traffic tickets (交通罚款). He was among the first suspects to be investigated, and evidence linking him to the murdered couple was found. He was arrested, and is now waiting for trial (审判).51. The computer DIDN'T help the police ______.A. to find the suspectB. to find the murdered coupleC. to arrest the suspectD. to search a 1950 or 1951 Chevrolet

共用题干“Lucky” Lord Lucan一Alive or DeadOn 8th November 1974 Lord Lucan,a British aristocrat,vanished. The day before,his children's nanny 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 tech-niques 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 MacLaugh-lin,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 1996.In the end the claim turned out be a case of mistaken identity. The man who died in 1996 was really Haplin,an exschoolteacher 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.Lucan could have been killed because people______.A: didn't want the police to catch himB: thought he might talk to the police about them if he was caughtC: were unhappy with himD: thought he was rich
共用题干第三篇 The Body ThievesIn the early nineteenth century in Britain,many improvements were being made in the world of medicine.Doctors and surgeons were becoming more knowledgeable about thehuman body.Illnesses that had been fatal a few years before were now curable.However, surgeons had one problem.They needed dead bodies to cut up,or dissect（解剖）.This was the only way that they could learn about the flesh and bones inside the body,and the only way to teach new surgeons to carry out operations.The job of finding these dead bodies was carried out by an unpleasant group of people called "body snatchers". They went into graveyards（墓地）at night and, using woodenshovels to make less noise,dug up any recently buried bodies.Then they took the bodies to the medical schools and sold them.A body could be sold for between ￡5 and ￡10, which was a lot of money at that time.The doctors who paid the body snatchers had an agreement with them一they never asked any questions.They did not desire to know where the bodies came from,as long as they kept arriving.The most famous of these body snatchers were two men from Edinburgh called William Burke and Wil!iam Hare.Burke and Hare were different because they did not」ust dig up bodies from graveyards.They got greedy and thought of an easier way to find bodies. Instead of digging them up,they killed the poorer guests in Hare's small hotel.Dr Knox, the respected surgeon they worked for,never asked why all the bodies they brought him had been strangled（勒死）.For many years Burke and Hare were not caught because,unsurprisingly,the bodies of their victims were never found by the police.They were eventually arrested and put ontrial in 1829.The judge showed mercy to Hare and he was released but Burke was found guilty and his punishment was to be hanged.Appropriately,his body was given to the medical school and he ended up on the dissecting table,just like his victims.In one small way，justice was done.Now,over 1 50 years later,surgeons do not need the help of criminals to learn their skills.However,the science of surgery could not have developed without their rather gruesome（令人毛骨惊然的）help.The bodies of Burke's and Hare's victims couldn't be found by the police becauseA: they had been stolen.B:they had been strangled.C: they had been dissected.D:they had been buried.
