A woman in the US is able to speak for the first time in 11 years after a pioneering voice box transplant (移植) .
Brenda Jensen said the operation was a great success which had saved her life.Thirteen days after the surgery she said her first words: "Good morning, I want to go home."It is the first time a voice box and windpipe have been transplanted at the same time and only the second time a voice box has ever been transplanted.
Ms.Jensen, 52, had been unable to speak on her own since her voice box was damaged during surgery in 1999.Since then, she has been unable to taste or smell food, could breathe only through a hole in her windpipe and could talk only with the help of an electronic voice box.
In October, surgeons at the University of California Davis Medical Centre removed the voice box and 6cm of the windpipe from a donor body.In an 18-hour operation, this was transplanted into Ms.Jensen's throat and the team connected it to her blood supply and nerves (神经).
Professor Martin Birchall from University College London, who was part of the surgery team, said: "We've learned that we can repair nerves to make even very complex organs function again. It'll open the door to better facial transplants and will be extremely important as tissue engineering develops."
A voice box transplant might be life changing, but it is not life saving.Everyone who receives a transplant must take drugs to control the immune system (免疫系统) for the rest of their lives. These drugs can reduce life expectancy, so they are normally set aside for life saving procedures.
One of the reasons Ms.Jensen was a suitable person for this transplant was that she was already taking immune controlling drugs after a kidney-pancreas transplant four years ago.Professor Peter Belafsky , part of the surgical team, said: " Brenda was an exceptional candidate for the transplant because she was highly motivated.Anyone who's met Brenda knows that she is a strong and determined person with a great outlook on life in spite of the many physical challenges she's faced over her lifetime.
63.The voice transplant operation is of great significance because it proves that ____.
A.facial transplants are now easier to perform
B.new medical technology is always possible to discover
C.nerve repairing is a breakthrough in tissue engineering
D.the drugs taken after the operation help the patient live longer
64.Ms.Jensen was a suitable person for this transplant because she was ____.
A.strong-willed and prepared B.experienced and brave
C.seriously ill and motivated D.determined and realistic
65.Which of the following is the right time order of the event?
a.Ms.Jensen received a voice box transplant operation.
b.Ms.Jensen began to take immune controlling drugs.
c.Doctors removed the voice box from a donor body.
d.Ms.Jensen had a kidney-pancreas transplant operation.
A.acdb B.dbca C.bdca D.cabd
66.Which is the best title for the passage?
A.Transplant Saves A Woman's Life B.Overcoming Obstacles to Speak Again
C.First Words from New Voice Box D.Courageous Woman Defeating Fears
