The most extraordinary dream I ever had was one in which I fancied that, as I was going into a theater, the cloak-room attendant (21) me in the lobby and insisted on my (22) my legs behind. I was notsurprised; but I was considerably annoyed. I said I had (23) heard of such a rule at any respectable theater (24) , and that I considered it a most absurd regulation.

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.
共用题干第三篇Swiss BanksSince the early 1930s,Swiss banks had prided themselves on their system of banking secrecy and numbered accounts.Over the years,they had successfully withstood every challenge to this system by their own government who, in turn,had been frequently urged by foreign governments to reveal information about the financial affairs of certain account holders.The result of this policy of secrecy was that a kind of mystique had grown up around Swiss banking. There was a widely-held belief that Switzerland was irresistible to wealthy foreigners,mainly because of its numbered accounts and bankers' reluctance to ask awkward questions of depositors.Contributing to the mystique was theview,carefully propagated by the banks themselves,that if this secret was ever given up,foreigners would fall over themselves in the rush to withdraw money,and the Swiss banking system would virtually collapse overnight.To many,therefore,it came like a bolt out of the blue,when,in 1977,the Swiss banks announced they had signed a pact with the Swiss National Bank(the Central Bank).The aim of the agreement was to prevent the improper use of the country's bank secrecy laws, and its effect to curb （遏制）severely the system of secrecy.The rules which the banks had agreed to observe made the opening of numbered accounts subject to much closer scrutiny than before.The banks would be required,if necessary,to identify the origin of foreign fund going into numbered and other accounts.The idea was to stop such accounts being used for dubious（可疑的）purposes.Also,they agreed not to accept funds resulting from tax evasion or from crime.The pact represented essentially a tightening up of banking rules.Although the banks agreed to end relations with clients whose identities were unclear or who were performing improper acts,they were still not obliged to inform on a client to anyone,including the Swiss government.To some extent,therefore,the principle of secrecy had been maintained.In the last paragraph,the writer thinks that________.A:complete changes had been introduced into Swiss banksB:Swiss banks could no long keep client informationC:changes in the bank policies had been somewhat superficialD:more changes need to be considered and made
