22、form New York. It was the first complete telesurgery procedure performed by surgeons nearly 4, 000 miles away from their patient. In New York, Marescaux teamed up with surgeon Michel Gagner to perform the historic longdistance operation. A high-speed fiber-optic service provided by France Telecom ma

23、de the connection between New York and Strasbourg. The two surgeons controlled the instruments using an advanced robotic surgical system, designed by Computer Motion Inc. that enabled the procedure to be minimally invasive. The patient was released from the hospital after about 48 hours and regained

24、 normal activity the following week. The high-speed fiber-optic connection between New York and France made it possible to overcome a key obstacle to telesurgery time delay. It was crucial that a continuous time delay of less than 200 milliseconds be maintained throughout the operation, between the

25、surgeons movements in New York and the return video(from Strasbourg)on his screen. The delay problem includes video coding decoding and signal transmission time. France Telecoms engineers achieved an average time delay of 150 milliseconds. “ I felt as comfortable operating on my patient as if I had

26、been in the room,“ says Marescaux. The successful collaboration(合作 )among medicine, advanced technology, and telecomm unications is likely to have enormous implications for patient care and doctor training. Highly skilled surgeons may soon regularly perform especially difficult operations through lo

27、ng-distance procedures. The computer systems used to control surgical movement can also lead to a breakthrough in teaching surgical techniques to a new generation of physicians. More surgeons-in-training will have the opportunity to observe their teachers in action in telesurgery operating rooms aro

28、und the world. Marescaux describes the success of the remotely performed surgical procedure as the beginning of a “third revolution“ in surgery within the last decade. The first was the arrival of minimally invasive surgery, enabling procedures to be performed with guidance by a camera, meaning that

29、 the abdomen(腹部 )and thorax(胸腔 )do not have to be opened. The second was the introduction of computer-assisted surgery, where complicated software algorithms(计算法 )enhance the safety of the surgeons movements during a procedure, making them more accurate, while introducing the concept of distance bet

30、ween the surgeon and the patient. It was thus natural to imagine that this distance-currently several meters in the operating room could potentially be up to several thousand kilometers. 41 The title that best expresses the main idea is_. （ A） How the Second Revolution in Surgery Comes Out （ B） The

31、Telesurgery Revolution （ C） A Patient Was Saved （ D） Dream Comes True 42 The italicized word “telesurgery“(Para. 1, Sentence 2)can be best explained as_. （ A） an operation done over a distance （ B） an operation done on television （ C） an operation demanding special skill （ D） an operation demanding

32、high technology 43 How long did it take the patient to resume her normal activity after the operation? （ A） 24 hours. （ B） 48 hours. （ C） About a week. （ D） Almost a month. 44 What is the major barrier to telesurgery? （ A） Distance. （ B） Advanced technology. （ C） Delay. （ D） Medical facilities. 45 T

33、he writer implies that_. （ A） difficult operation can be successfully performed all over the world now （ B） compared to the “third revolution“ in surgery, the first two are less important （ C） all patients can be cured by a gall bladder-removal operation （ D） a new breakthrough has been made in surg

34、ery 45 The multi-billion-dollar Western pop music industry is under fire. It is being blamed by the United Nations for the dramatic rise in drug abuse worldwide. “The most worrisome development is a culture of drug-friendliness that seems to be gaining prominence(显著 ),“ said the UNs 13-member Intern

35、ational Narcotics Control Board in a report released in late February 1998. The 74-page study says that pop music, as a global industry, is by far the most influential trendsetter for young people of most cultures. “Some lyrics advocate the smoking of marijuana(大麻 )or taking other drugs, and certain

36、 pop stars make statements and set examples as if the use of drugs for non-medicinal purposes were a normal and acceptable part of a persons lifestyle,“ the study says. “Surprisingly,“ says the Board, “the effect of drug-friendly pop music seems to survive despite the occasional shock of death by ov

37、erdose(过量用药 ).“ “ Such incidents tend to be seen as an occasion to mourn the loss of a role model, and not an opportunity to confront the deadly effect of recreational drug use,“ it notes. Since the 1970s, several internationally famous singers and movie stars including Elvis Presley, Janice Joplin,

38、 John Belushi, Jimi Hendrix, Jonathan Melvin and Andy Gibbs have died of either drug abuse or drug related illnesses. With the globalization of popular music, messages tolerating or promoting drug abuse are now reaching beyond their countries of origin. “In most countries, the names of certain pop s

39、tars have become familiar to the members of every household,“ the study says. The UN study also blames the media for its description of certain drug issues especially the use of marijuana and issues of liberalization and legalization which encourages, rather than prevents, drug abuse. “Over the last

40、 years, we have seen how drug abuse is increasingly regarded as being acceptable or even attractive,“ says Hamid Ghodse, president of die Board. “Powerful pressure groups run political campaigns aimed at legalizing controlled drugs,“ he says. Ghodse also points out that all these developments have c

41、reated an environment which is tolerant of or even favorable to drug abuse and spoils international drug prevention efforts currently underway. The present study, he says, focuses on the issue of demand reduction and prevention within an environment that has become tolerant of drug abuse. The Board

42、calls on governments to do their legal and moral duties, and to act against the pro-drug messages of the youth culture to which young people increasingly are being exposed. 46 Which of the following statements does the author tend to agree with? （ A） The use of drugs for non-medicinal purposes is an

43、 acceptable part of a persons lifestyle. （ B） The spreading of pop music may cause the drug abuse to go beyond the boundaries of the country. （ C） No efforts have been made to prevent the spreading of drug abuse. （ D） The governments have no ability to act against the pro-drug messages of the youth

44、culture. 47 The italicized phrase “under fire“(Para. 1, Sentence 1)means_. （ A） in an urgent situation （ B） facing some problems （ C） being criticized （ D） quite popular 48 Under the influence of drug-friendly pop music, what might the youth think of the death of some pop stars caused by overdose? （

45、 A） They tend to mourn the pop stars as role models. （ B） They are shocked to know even pop stars may abuse drugs. （ C） They try to confront the deadly effect of “recreational“ drag use. （ D） They may stop abusing the drugs. 49 Which of the following is not mentioned in the passage as a factor that

46、has contributed to creating an environment tolerant of or even favorable to drug abuse? （ A） The spreading of pop music. （ B） The media. （ C） Political campaigns run by powerful pressure groups. （ D） The low price of some drugs. 50 The pop music_. （ A） has a great influence on young people of most c

47、ultures （ B） only appeals to a small number of young people （ C） is not a profitable industry （ D） is the only culprit(罪魁祸首 )responsible for drug amuse 50 Rubidium, potassium and carbon are three common elements used to date the history of Earth. The rates of radioactive decay of these elements are

48、absolutely regular when averaged out over a period of time; nothing is known to change them. To be useful as clocks, the elements have to be fairly common in natural minerals, unstable but decay slowly over millions of years to form recognizable “daughter“ products which are preserved minerals. For

49、example, an atom of radioactive rubidium decays to form an atom of strontium(another element)by converting a neutron in its nucleus to a proton and releasing an electron, generating energy in the process. The radiogenic daughter products of the decay in this case strontium atoms diffuse away and are lost above a very high temperature. So by measuring the exact proportions of rub
