Deveza's mother was on the waiting list for a kidney transplant（腎移植）.Deveza wanted to donate one of her own kidneys—but she was turned down because she might develop the same health problems as her mother in later life.
Deveza came up with a different plan.In 2017，she started the world's first paired exchange of different organs between living donors，exchanging half her liver（肝） for someone else's kidney.A case study of the organ exchange has now been published，and the surgeons who were involved are calling for more exchanges like this. "You can imagine the enormous impact for mixed organ extended chains，" says John Roberts，a surgeon at University of California，San Francisco.
Most organ transplants come from people who have died，but there are never enough organs.As most people can manage with just one of their kidneys，people with kidney failure are increasingly receiving donated organs from relatives or friends.If someone wants to donate but their immune（免疫的） system is unsuited，doctors may be able to find pairs of would-be donors who can each give a kidney to the other's relative.
When Deveza was looking into such chains，she came across research describing the idea of trading a kidney with the only other organ generally taken from a living donor—the liver.She suggested the idea to many hospitals before she finally contacted Roberts，who saw the idea's potential.
Deveza was assessed to be in good enough health to donate part of her liver.It then took 18 months to find Annie Simmons，in Idaho，whose liver was unsuitable to use as a transplant for her sister with severe liver disease.They drew up a plan：Simmons would donate a kidney to Deveza's mother，and in return，Deveza would give half her liver to Simmons' sister.The hospital gave the go-ahead and the four operations took place on the same day successfully.
The team hope that the ground-breaking case will inspire more people to consider doing the same.Roberts says that direct exchanges involving two donors could enable up to thirty extra living-donor liver transplants a year—a ten percent increase.

2．Nuclear bombs.That's the go-to answer for incoming space objects like asteroids（小行星） and comets，as far as Hollywood is concerned.Movies like Deep Impact and Armageddon rely on nuclear weapons，delivered by stars like Bruce Willis，to save the world and deliver the drama.
But planetary defense experts say in reality，if astronomers spotted a dangerous incoming space rock，the safest and best answer might be something more subtle，like simply pushing it off course by crashing it with a small spacecraft.
That's just what NASA did on Monday evening，when a spacecraft headed straight into an asteroid called Dimorphous，which is around 7 million miles away and poses no threat to Earth.It's about 525 feel across and orbits another larger asteroid.
In images streamed as the impact neared，the egg-shaped asteroid grew in size from a little spot on screen to have its full rocky surface come quickly into focus before the signal went dead as the craft hit right on target.
Events happened exactly as engineers had planned，they said，with nothing going wrong. "As far as we can tell，our first planetary defense test was a success，" said Elena Adams，the mission systems engineer，who added that scientists looked on with "both terror and joy" as the spacecraft neared its final destination.
The impact was the peak of NASA's Double Asteroid Redirection Test （DART） ，a 7-year and more than ﹩300 million effort which launched a space vehicle in November of 2021 to perform humanity's first ever test of planetary defense technology.It will be about two months，scientists said，before they will be able to determine if the impact was enough to drive the asteroid slightly off course，probably shortening its original orbit.
NASA plans to launch an asteroid-hunting space telescope named NEO Surveyor in 2026. "We've tacked lots of space rocks，especially the larger ones that could cause extinction-level events.Thankfully，none currently threaten Earth.But many asteroids the size of Dimorphous haven't yet been discovered，and those could potentially take out a city if they came crashing down." explains Lindley Johnson，NASA's Planetary Defense Officer.
（1）How did scientists know the craft hit the asteroid successfully？
A．The signal from the craft was lost as it hit the target.
B．They recorded the whole process with a telescope.
C．The little spot on the screen suddenly disappeared.
D．They monitored the craft with satellites in space.
（2）What is the purpose of launching the spacecraft？
A．To search for evidence of alien life.
B．To end the asteroid's threat to Earth.
C．To save the world and deliver a drama.
D．To test technology for defending Earth.
（3）What can be inferred about Dimorphous？
A．It is a dangerous incoming space rock.
B．It is an egg-shaped asteroid around Earth.
C．It may orbit the same asteroid after the hit.
D．It is expected to blow up after the impact.
（4）Which statement will Lindley Johnson probably agree with？
A．Asteroids are equally destructive whatever the size.
B．NEO Surveyor is aimed to track smaller asteroids.
C．Larger asteroids will no longer threaten Earth.
D．NASA is responsible for the safety of Earth.發(fā)布：2024/12/11 2:0:1組卷：6引用：4難度：0.5 -
