First Self-contained Heart Implanted
A patient on the brink（边缘）of death has received the world's first self-contained artificial heart-a battery-powered device about the size of a softball that runs without the need for wires,tubes sticking out of the chest.
Two surgeons from the University of Louisville implanted the titanium（钛）and plastic pump during a seven-hour operation at Jewish 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 person's life by only a month.But the device is considered a major step toward improving the patient's 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 famous of those mechanical hearts,the Jarvic-7，used air as a pumping device and was attached to an apparatus about the size of a washing machine.
"I think it's potentially a major step forward in the artificial heart development,"said Dr.David
Faxon,president of the American Heart Association.However,he said the dream of an implantable,perma- nent 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.Some doctors,including Robert Higgins,chairman of cardiology at the Medical Col-lege of Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts.
"A donor heart in a good transplant can last 15 to 30 years."he said,"It's going to be hard to replace that with a machine."

共用题干Stem Cell Therapy May Help Repair the HeartAccording to scientists in the USA,stem cell therapy may one day be able to repair the hearts of people with heart failure.Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery.They injected stem cells into the parts of their hearts that were damaged.They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure).The patients who had had the stem cells injected had hearts that were able to pump（用泵抽运） more blood than the others.According to Professor Robert Kormos,one of the researchers,these results could revolutionize heart treatment.Although previous studies had indicated that there might be a benefit,this is the first study that has actually proved that stem cell therapy can help thefailing heart work better．All the patients in this study had hearts that could not pump blood properly.The scientists measured their ejection fraction（射血分数）.This is a measure of heart performance;you measure how much blood is being pumped out by the left ventricle（心室）.Healthy people's ejection fraction is about 55%.These patients had ejection fraction ofunder 35%. They all had by-pass surgery（搭桥手术）performed on them. Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle.Six months later their ejection fraction rate was 46.1%while those who just had surgery but no stem cell injections averaged 37. 2%.No side effects were reported.Heart failure is a common problem all over the world.In the UK alone about 650, 000 people suffer from heart failure every year. As the number of people suffering from heart failure increases in the world in general these findings are particularly significant.Current treatments relieve the symptoms.This new stem cell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease. Heart failure is more common in the UK than anywhere else in the world.A:Right B:Wrong C:Not mentioned
共用题干第三篇First Self-contained Heart ImplantedA patient on the brink（边缘）of death has received the world's first self-contained artificial heart-a battery-powered device about the size of a softball that runs without the need for wires,tubes sticking out of the chest.Two surgeons from the University of Louisville implanted the titanium（钛）and plastic pump during a seven-hour operation at Jewish 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 person's life by only a month.But the device is considered a major step toward improving the patient's 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 famous of those mechanical hearts,the Jarvic-7，used air as a pumping device and was attached to an apparatus about the size of a washing machine."I think it's potentially a major step forward in the artificial heart development,"said Dr.DavidFaxon,president of the American Heart Association.However,he said the dream of an implantable,perma- nent 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.Some doctors,including Robert Higgins,chairman of cardiology at the Medical Col-lege of Virginia in Richmond,said artificial hearts are unlikely to replace donor hearts."A donor heart in a good transplant can last 15 to 30 years."he said,"It's going to be hard to replace that with a machine."According to Dr.David Faxon,the self-contained heart is______.A:a milestone in the artificial heart developmentB:still in the experimental stageC:an implantable,permanent artificial heartD:unavailable to all those Americans waiting for donor hearts

共用题干Stem Cell Therapy May Help Repair the HeartAccording to scientists in the USA,stem cell therapy may one day be able to repair the hearts of people with heart failure.Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery.They injected stem cells into the parts of their hearts that were damaged.They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure).The patients who had had the stem cells injected had hearts that were able to pump（用泵抽运） more blood than the others.According to Professor Robert Kormos,one of the researchers,these results could revolutionize heart treatment.Although previous studies had indicated that there might be a benefit,this is the first study that has actually proved that stem cell therapy can help thefailing heart work better．All the patients in this study had hearts that could not pump blood properly.The scientists measured their ejection fraction（射血分数）.This is a measure of heart performance;you measure how much blood is being pumped out by the left ventricle（心室）.Healthy people's ejection fraction is about 55%.These patients had ejection fraction ofunder 35%. They all had by-pass surgery（搭桥手术）performed on them. Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle.Six months later their ejection fraction rate was 46.1%while those who just had surgery but no stem cell injections averaged 37. 2%.No side effects were reported.Heart failure is a common problem all over the world.In the UK alone about 650, 000 people suffer from heart failure every year. As the number of people suffering from heart failure increases in the world in general these findings are particularly significant.Current treatments relieve the symptoms.This new stem cell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease.The study actually proved for the first time the benefit of stem cell therapy.A:Right B:Wrong C:Not mentioned

共用题干New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with. The Arabic legend is used to prove thatA:.coffee was first discovered by KaldiB: coffee was first discovered by Kaldi's goatsC:.coffee was first discovered in south American countriesD: coffee drinks were first made by Arabs
共用题干第三篇Shouldn't We Know Who Invented the Windshield WiperWe know the famous ones一the Thomas Edison and the Alexander Graham Bells一but what about the less famous inventors?What about the people who invented the traffic light and the windshield wiper（雨刷器）?Shouldn' t we know who they are?Joan Mclean thinks so.In fact,Mclean,a professor of physics at Mountain University in Range,feels so strongly about this matter that she's developed a course on the topic.In addition to learning" who"invented"what",however,Mclean also likes her students to learn the answers to the"why"and"how" questions.According to Mclean,"when students learn the answers to these questions,they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try".Her students agree.One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement."If I had not heard of the story of the windshield wiper's invention,"said Tommy Lee,a senior physics major,"I never would have dreamed of turning my bad experience during a rainstorm into something so constructive."Lee is currently negotiating to sell his patent to an umbrella producer.So,just what is the story behind the windshield wiper? Well,Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy,but Anderson still wanted to see the sights,so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield,she found herself wondering why there couldn't be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham,Alabama,Anderson started drafting out solutions. One of her ideas,a lever（操作杆）on the inside of a vehicle that would control an arm on the outside,became the first windshield wiper.Today we benefit from countless inventions and innovations,It's hard to imagine driving without Garrett A.Morgan's traffic light. It'5equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible.Can you picture life without clear windows and eyeglasses?Which of the following is NOT true?A:The first windshield wiper was invented in New York City.B:Mary made a visit to New York City.C:When Anderson returned home,she still remembered her inspirations on the way.D:Mary Anderson invented a lever on the inside of a vehicle that became the first windshield wiper.
