8、lds first self-contained artificial heart a battery-powered device about the size of a softball that runs without the need for wires, tubes or hoses sticking out of the chest. Two surgeons from the University of Louisville implanted the titanium and plastic pump during a seven-hour operation at Jewi

9、sh Hospital Monday. The hospital said the patient was“ awake and responsive“ Tuesday and resting comfortably. It refused to release personal details. The patient had been expected to die within a month without the operation, and doctors said they expected the artificial heart to extend the persons l

10、ife by only a month. But the device is considered a major step toward improving the patients quality of life. The new pump, called AbioCor, is also a technological leap from the mechanical hearts used in the 1980s, which were attached by wires and tubes to bulky machinery outside the body. The most

11、famous of those, the Jarvic-7, used air as a pumping device and was attached to an apparatus about the size of a washing machine. “ I think its potentially a major step forward in the artificial heart development, “ said Dr. David Faxon, president of the American Heart Association. However, he said

12、the dream of an implantable , permanent artificial heart is not yet a reality, “ This is obviously an experimental device whose long-term success has to be demonstrated. “ Only about half of the 4, 200 Americans on a waiting list for donor hearts received them last year, and most of the rest died. S

14、he AbilCor has a 2-pound pumping unit, and electronic controls that adjust the pumping speed based on the bodys needs. It is powered by a small battery pack worn outside the body that transmits current through the skin. 16 The pump of the first implanted self-contained heart was made of titanium and

15、 plastic. （ A） Right （ B） Wrong （ C） Not mentioned 17 The patients life was expected to last several years longer by implanting the artificial heart. （ A） Right （ B） Wrong （ C） Not mentioned 18 There is no difference in structure between the self-contained heart and the mechanical heart. （ A） Right

16、（ B） Wrong （ C） Not mentioned 19 The American Heart Association recommended widely using the self-contained heart. （ A） Right （ B） Wrong （ C） Not mentioned 20 Dr. David Faxon believed that the implantable, permanent artificial heart will certainly be developed in the future. （ A） Right （ B） Wrong （

17、C） Not mentioned 21 Approximately two thousand one hundred patients received heart implantation in America last year. （ A） Right （ B） Wrong （ C） Not mentioned 22 Some doctors doubt the possibility of donor hearts being replaced by artificial ones. （ A） Right （ B） Wrong （ C） Not mentioned 三、 概括大意与完成句

20、ress“ and in front of the rooms advanced machinery registers every move the volunteers make. Each day, meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer. 2 Nicola Walters is one of twenty volunteers who, over the past eight months, hav

21、e spent varying periods inside the calorimeter. Tall and slim, Nicola does not have a weight problem, but thought the strict diet might help with her training and fitness programme. As a self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert fo

22、r volunteers at her local gym and as she is interested in the whole area of diet and exercise, she thought she would help out. 3 The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence was repeated four times over six weeks. She arrived

23、at the calorimeter at 8: 30 am on each of the four mornings and from then on everything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine, timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and s

24、amples were taken for analysis. 4 The scientists help volunteers impose a kind of order on the long days they face in the room. “ The first time, I only took one video and a book, but it was OK because I watched TV the rest of the time, “ says Nicola. And twice a day she used the exercise bike. She

25、pedaled(踩踏板 )for half an hour, watched by researchers to make sure she didnt go too fast. 5 It seems that some foods encourage you to eat more, while others satisfy you quickly.

47、r a new era of mass production. Companies in the US are developing the technology needed to“ clone“chickens on a massive scale. Once a chicken with desirable traits has been bred or genetically engineered, tens of thousands of eggs, which will hatch into identical copies, could roll off the producti

48、on lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount of meat and taste the same. This, at least, is the vision of the USs National Institute of Science and Technology, which has given Origen Therap

49、eutics of Burlingame, California, and Embrex of North Carolina $ 4. 7 million to help fund research. The prospect has alarmed animal welfare groups, who fear it could increase the suffering of farm birds. Thats unlikely to put off the poultry industry, however, which wants disease-resistant birds that grow faster on less food. “ Producers would like the same meat quantity but to use reduced inputs to get there, “says Mike
