Transplanted organs usually come from people who have died, but who wanted their organs to be used to help other people live. But there are far more patients with kidney trouble than there are kidneys.
For years, scientists have tried to figure out how to transplant organs from other animals into humans. This is hard because the human body almost always rejects something that isn’t its own. More recently, scientists have focused on transplants from pigs. In many ways, pigs’ bodies are similar to humans. It’s fairly easy to raise pigs, and they grow quickly.
To prevent pig organs from being rejected by the patient’s body, scientists have been experimenting with “gene editing” to change the pig’s DNA. Scientists have made several changes to the pig’s DNA, and even added some things normally found in human DNA. Some kidneys have come from pigs with as many as 69 changes to their DNA.
In the last few years, these methods have led to greatly improved results. Early pig transplants were successful, but only for a short time. But in 2024, a woman lived with a pig kidney for over four months before going on dialysis again.
Tim Andrews is a 67-year-old man.He set a new record by living with a pig kidney for nearly nine months before going back on dialysis. Mr. Andrews is still waiting for a human transplant, but his long success with a pig kidney has encouraged many people.
The pig transplant trial program could help scientists answer a lot of questions. It will provide new information about the safety – as well as the challenges – of the process. It will also teach them about which gene edits work best. Most importantly, it could help them discover how to help patients live longer with pig transplants.

移植器官通常来源于已故但希望其器官用于帮助他人存活的捐献者。然而,肾功能障碍患者数量远超可用肾脏数量。
多年来,科学家一直致力于探索如何将其他动物的器官移植到人体内。这一过程具有挑战性,因为人体几乎总是会排斥非自身组织。近年来,研究重点转向猪源器官移植。从多方面来看,猪与人类具有相似性,猪的饲养相对简便,且生长周期较短。
为防止猪器官被患者机体排斥,科学家们一直在尝试通过“基因编辑”技术改变猪的DNA。研究人员已对猪的DNA进行了多项修改,甚至添加了某些通常存在于人类DNA中的序列。部分肾脏取自DNA修改次数高达69次的猪。
近年来,这些方法已取得显著改善。早期猪肾移植虽获成功,但仅维持短期效果。然而2024年,一名女性患者在移植猪肾后存活超过四个月,之后再次接受透析治疗。
蒂姆·安德鲁斯(Tim Andrews)是一名67岁男性。他创下了一项新纪录——在停止透析前,他依靠猪肾维持了近九个月的生命。安德鲁斯先生目前仍在等待人类肾脏移植,但其长期使用猪肾的成功案例已激励了众多患者。
猪移植试验项目可帮助科学家解答诸多问题。该项目将提供关于该过程安全性及挑战的新信息,同时指导科学家确定哪些基因编辑方案效果最佳。最重要的是,该项目可能帮助科学家发现如何通过猪移植技术延长患者生存期。

Passage1阅读理解
(2026·江苏省南京市七校联合体联考)
The shortage of transplantable organs is a major global medical challenge, but a medical team from China seems to have found one of the most promising solutions to this problem.
“Here, we report a case of pig-to-human lung xenotransplantation (异种移植), in which a lung from a pig was transplanted into a 39-year-old brain-dead male human recipient following a brain haemorrhage (大出血),” the researchers wrote in a study published in the journal Nature Medicine.
Before the procedure, the scientists edited six genes of the pig to remove proteins that could trigger severe immune responses in humans, thus reducing rejection risks.
In the experimental surgery, the team transplanted the left lung of the gene-edited pig into a brain-dead man, while leaving his original right lung undamaged. Post-surgery monitoring showed the transplanted lung maintained gas exchange functions for up to nine days, without signs of immediate rejection or active infection.
However, complications emerged: lung edema (水肿) was observed within 24 hours, and antibody-mediated rejection appeared on day 6, leading to the ending of the experiment on day 9.
International experts praised the achievement as a “milestone” in addressing the global shortage of lung donors, though they noted that further research is needed to improve gene editing and immunosuppressive (免疫抑制的) therapies before clinical application.
Xenotransplantation technology holds great significance. Taking pigs as donors for xenotransplantation as an example, pig organs are similar to human organs in terms of tissue structure and physiological functions. Meanwhile, pigs have a relatively distant genetic relationship with humans, which reduces the risk of transmitting zoonotic diseases. Additionally, pigs have the advantages of low breeding costs, rich varieties, and excellent reproductive capabilities, making them ideal candidate donors for xenotransplantation. If this technology can be successfully developed and widely applied, it will effectively ease the severe global shortage of organ donors, bringing new hope to a large number of patients waiting for organ transplants and giving them the opportunity to regain their lives.
1.What can we learn from the first three paragraphs?
A.The shortage of transplantable organs will soon be solved.
B.A lung from a pig saved a brain-dead male human recipient.
C.A Chinese medical team saved a man from brain haemorrhage.
D.Special gene editing is necessary to reduce potential rejection risks.
2.Which statement about the lung transplant is true?
A.It was a total failure and needed more research.
B.It was the first case of organ xenotransplantation.
C.Lung edema and rejection led to the ending of the experiment.
D.The transplanted lung failed to exchange gas in the man’s body.
3.What is the attitude of international experts towards this experiment?
A.Negative. B.Positive. C.Doubtful. D.Objective.
4.What is the main idea of the last paragraph?
A.Pigs are genetically similar to humans.
B.Pigs are perfect for xenotransplantation.
C.Xenotransplantation technology is of great importance.
D.Xenotransplantation technology still has a long way to go.
Passage2阅读理解
(2026·江苏省盐城市七校联盟第二次联考)
Heart disease is the leading cause of death in the United States. A transplant (移植) is the only treatment available to patients with end-stage heart failure, but there is a severe shortage of heart donors. That means there’s an urgent need to develop new ways to regenerate a diseased heart. Now the good news is that the world’s first complete 3D-printed heart, made using the patient’s own cells and materials, has been created in a lab.
Until now, success has been limited to printing only simple tissues without blood vessels (血管). “This is the first time anyone has successfully printed an entire heart anywhere,” said team leader Tal Dvir.
The 3D-printed heart is only about a third the size of an actual human heart and it doesn’t actually work. But it’s a groundbreaking step toward engineering customized (定制的) organs that can be transplanted with less risk of rejection. Dvir noted that scientists have managed to print a 3D structure of a heart before, but not with cells or blood vessels. The use of biological materials from a patient is key to successful engineering of tissues and organs.
Ideally, the biomaterial should possess the same biochemical and mechanical properties of the patients’ own tissues. This way, their bodies will be less likely to reject the organ, making transplants much safer.
While the 3D-printed heart is about a third the size of a human heart, the same technology can be used to print a normal-sized one. The team’s next step is to culture (培养) printed hearts in the lab and “teach them to behave” like real hearts. Then, researchers plan to transplant the 3D-printed heart into lab animals.
“Our results demonstrate the potential of our approach to engineering personalized tissue and organ replacement in the future,” Dvir said. “Maybe in 10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely.”
5.What can be inferred from the world’s first complete 3D-printed heart?
A.It makes organ transplants risk-free.
B.It bridges gaps in biological organ printing.
C.It solves the donor shortage for heart transplants.
D.It has the same properties as natural heart tissues.
6.What does Dvir imply about the previous 3D-printed heart structures in paragraph 3?
A.They were ready for transplant to animals.
B.They matched the size of real human hearts.
C.They lacked cell-based biological components.
D.They contained complete blood vessel networks.
7.What will Dvir’s team do in the future?
A.They will first test printed hearts on humans.
B.They will focus on curing early heart failure.
C.They will change the biological materials used.
D.They will improve the heart’s functional performance.
8.What’s Dvir’s attitude towards the 3D printing technology?
A.Positive. B.Doubtful. C.Negative. D.Indifferent.
Passage 3 阅读七选五

Doctors have successfully kept a heart beating in a container for 24 hours, bringing hope to thousands of patients across the world in need of a life-saving transplant.
1 However, the "game-changing" device can preserve a heart up to six times longer than existing methods. It provides the heart with oxygen and vital nutrients, allowing more time to transport it.
The device, named ULiSSES, fits into a carry-on box, so hearts can be flown around the world. 2 And it is expected to cost under $ 100,000. University of Texas researchers have successfully tested on pig hearts, which are similar to ours. 3
Dr. Rafael Veraza presented the findings on pig hearts at the annual meeting of the American Association for the Advancement of Science in Seattle.
" 4 Many years later, it is done much the same way," Dr. Veraza said. "Donated hearts generally remain viable (可存活的) for around four hours using traditional preservation methods. 5 Being able to keep a heart viable for 24 hours means you could transport it almost anywhere in the world, and this could save many lives."
A.It is expected to come into use soon.
B.The extra time could bring more hope to patients.
C.Usually, a donated heart can only last about four hours.
D.It works without being affected by temperature or air pressure.
E.The pig hearts remained viable for 24 hours after they were removed.
F.The first heart was transported more than 50 years ago by putting it on ice.
G.They plan to test it on human hearts in three months and put it on the market within a year.

“I wasn’t sure if my son would be the one, but I did bring it up to my 8 ,” Mondek recalled. “Could a 9-year-old who’s only 70 pounds potentially get us 9 stem cells to make this a successful transplant?” As a doctor and parent, Mondek didn’t want Stephen to feel obliged or 10 . He didn’t even tell Stephen they were down to him as their last 11 . Starting the conversation with his young son was “nerve-wracking” but ultimately led to the best 12 .
“Would you consider potentially getting 13 to see if maybe you could be a donor?” Mondek asked. Without 14 , Stephen, described as a “shy” and “quiet” boy, said, When do we go?
Doctors at Cedars-Sinai successfully 15 stem cells from Stephen, and Mondek received his second stem cell transplant on July 30. Both father and son are now out of the hospital. Mondek said, Stephen is doing great. He is my hero.

Transplants (移植) usually come from people who have died, but want 5 (they) organs to be used to help other people live. There are far 6 (large) numbers of patients who need organs than those of organs. Over 3,800 Americans got heart transplants last year. But there are 7 (rough) 110,000 people who are waiting for some kind of transplant. For years, scientists have tried to figure out 8 they transplant organs from other animals into humans. This is hard because the human body almost always rejects something that isn’t its own.
Muhammad is one of the 9 (doctor) who helped perform the surgery. He’s been working to develop methods to help prevent pig organs 10 being rejected in humans. Doctors are watching Mr. Bennett’s recovery.

为防止猪器官被患者机体排斥,科学家们一直在尝试通过“基因编辑”技术改变猪的DNA。研究人员已对猪的DNA进行了多项修改,甚至添加了某些通常存在于人类DNA中的序列。部分肾脏取自DNA修改次数高达69次的猪。
近年来,这些方法已取得显著改善。早期猪肾移植虽获成功,但仅维持短期效果。然而2024年,一名女性患者在移植猪肾后存活超过四个月,之后再次接受透析治疗。
蒂姆·安德鲁斯(Tim Andrews)是一名67岁男性。他创下了一项新纪录——在停止透析前,他依靠猪肾维持了近九个月的生命。安德鲁斯先生目前仍在等待人类肾脏移植,但其长期使用猪肾的成功案例已激励了众多患者。
猪移植试验项目可帮助科学家解答诸多问题。该项目将提供关于该过程安全性及挑战的新信息,同时指导科学家确定哪些基因编辑方案效果最佳。最重要的是,该项目可能帮助科学家发现如何通过猪移植技术延长患者生存期。

(2026·江苏省南京市七校联合体联考)
The shortage of transplantable organs is a major global medical challenge, but a medical team from China seems to have found one of the most promising solutions to this problem.
“Here, we report a case of pig-to-human lung xenotransplantation (异种移植), in which a lung from a pig was transplanted into a 39-year-old brain-dead male human recipient following a brain haemorrhage (大出血),” the researchers wrote in a study published in the journal Nature Medicine.
Before the procedure, the scientists edited six genes of the pig to remove proteins that could trigger severe immune responses in humans, thus reducing rejection risks.
In the experimental surgery, the team transplanted the left lung of the gene-edited pig into a brain-dead man, while leaving his original right lung undamaged. Post-surgery monitoring showed the transplanted lung maintained gas exchange functions for up to nine days, without signs of immediate rejection or active infection.
However, complications emerged: lung edema (水肿) was observed within 24 hours, and antibody-mediated rejection appeared on day 6, leading to the ending of the experiment on day 9.
International experts praised the achievement as a “milestone” in addressing the global shortage of lung donors, though they noted that further research is needed to improve gene editing and immunosuppressive (免疫抑制的) therapies before clinical application.
Xenotransplantation technology holds great significance. Taking pigs as donors for xenotransplantation as an example, pig organs are similar to human organs in terms of tissue structure and physiological functions. Meanwhile, pigs have a relatively distant genetic relationship with humans, which reduces the risk of transmitting zoonotic diseases. Additionally, pigs have the advantages of low breeding costs, rich varieties, and excellent reproductive capabilities, making them ideal candidate donors for xenotransplantation. If this technology can be successfully developed and widely applied, it will effectively ease the severe global shortage of organ donors, bringing new hope to a large number of patients waiting for organ transplants and giving them the opportunity to regain their lives.
1.What can we learn from the first three paragraphs?
A.The shortage of transplantable organs will soon be solved.
B.A lung from a pig saved a brain-dead male human recipient.
C.A Chinese medical team saved a man from brain haemorrhage.

If this technology can be successfully developed and widely applied, it will effectively ease the severe global shortage of organ donors, bringing new hope to a large number of patients waiting for organ transplants and giving them the opportunity to regain their lives.(异种移植技术具有重要意义。以猪作为异种移植的供体为例,猪的器官在组织结构和生理功能上与人类器官相似。同时,猪与人类的遗传关系相对较远,这降低了传播人兽共患病的风险。此外,猪具有繁殖成本低、品种丰富、繁殖能力强等优点,是异种移植的理想候选供体。如果这项技术能够成功开发并广泛应用,将有效缓解全球器官供体严重短缺的问题,为大量等待器官移植的患者带来新的希望,让他们有机会重获新生。)”可知,最后一段主要讲述了异种移植技术的重要性。故选C。
Passage2阅读理解
(2026·江苏省盐城市七校联盟第二次联考)
Heart disease is the leading cause of death in the United States. A transplant (移植) is the only treatment available to patients with end-stage heart failure, but there is a severe shortage of heart donors. That means there’s an urgent need to develop new ways to regenerate a diseased heart. Now the good news is that the world’s first complete 3D-printed heart, made using the patient’s own cells and materials, has been created in a lab.
Until now, success has been limited to printing only simple tissues without blood vessels (血管). “This is the first time anyone has successfully printed an entire heart anywhere,” said team leader Tal Dvir.
The 3D-printed heart is only about a third the size of an actual human heart and it doesn’t actually work. But it’s a groundbreaking step toward engineering customized (定制的) organs that can be transplanted with less risk of rejection. Dvir noted that scientists have managed to print a 3D structure of a heart before, but not with cells or blood vessels. The use of biological materials from a patient is key to successful engineering of tissues and organs.
Ideally, the biomaterial should possess the same biochemical and mechanical properties of the patients’ own tissues. This way, their bodies will be less likely to reject the organ, making transplants much safer.
While the 3D-printed heart is about a third the size of a human heart, the same technology can be used to print a normal-sized one. The team’s next step is to culture (培养) printed hearts in the lab and “teach them to behave” like real hearts. Then, researchers plan to transplant the 3D-printed heart into lab animals.
“Our results demonstrate the potential of our approach to engineering personalized tissue and organ replacement in the future,” Dvir said. “Maybe in 10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely.”
5.What can be inferred from the world’s first complete 3D-printed heart?
A.It makes organ transplants risk-free.
B.It bridges gaps in biological organ printing.
C.It solves the donor shortage for heart transplants.
D.It has the same properties as natural heart tissues.
6.What does Dvir imply about the previous 3D-printed heart structures in paragraph 3?
A.They were ready for transplant to animals.
B.They matched the size of real human hearts.
C.They lacked cell-based biological components.
D.They contained complete blood vessel networks.
7.What will Dvir’s team do in the future?
A.They will first test printed hearts on humans.
B.They will focus on curing early heart failure.
C.They will change the biological materials used.
D.They will improve the heart’s functional performance.
8.What’s Dvir’s attitude towards the 3D printing technology?
A.Positive. B.Doubtful. C.Negative. D.Indifferent.
【答案】5.B 6.C 7.D 8.A
【解析】本文是一篇科技类说明文,主要介绍了世界上首个利用患者自身细胞和材料3D打印的完整心脏的突破性进展,并展望了该技术在器官移植领域的应用前景。
5.推理判断题。根据文章第二段“Until now, success has been limited to printing only simple tissues without blood vessels (血管). “This is the first time anyone has successfully printed an entire heart anywhere,” said team leader Tal Dvir.(到目前为止,所取得的成果仅仅是能够打印出不含血管的简单组织。团队负责人塔尔·德维尔表示:“这是首次有人在某地成功打印出完整的心脏。”)”可知,这是首次有人成功打印出完整心脏,此前仅能打印无血管的简单组织,因此推断该成果填补了生物器官打印的空白。故选B。
6.细节理解题。根据文章第三段“Dvir noted that scientists have managed to print a 3D structure of a heart before, but not with cells or blood vessels.( Dvir指出,科学家们此前确实曾成功打印出心脏的三维结构,但所使用的并非细胞和血管。)”可知,科学家此前打印的心脏结构不含细胞或血管,说明过去的打印结构缺乏生物细胞成分。故选C。
7.推理判断题。根据文章第五段“The team’s next step is to culture (培养) printed hearts in the lab and “teach them to behave” like real hearts.(该团队接下来的步骤是在实验室中培养打印心脏,并“教会它们像真正的心脏那样运作”。)”可知,团队下一步将培养打印心脏并教会它们像真实心脏一样工作,因此推断他们将改善心脏的功能性能。故选D。
8.推理判断题。根据文章末段Dvir的发言““Our results demonstrate the potential of our approach to engineering personalized tissue and organ replacement in the future,” Dvir said. “Maybe in 10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely.”(Dvir说“我们的研究结果表明,我们的方法在实现个性化组织和器官替换方面具有潜在应用价值。也许在十年后,世界各地顶尖的医院里将会配备器官打印设备,相关手术也将成为常规操作。”)”可知,我们的成果展示了未来个性化器官替代的潜力,及对10年后器官打印机普及的乐观预测,可见其态度是积极肯定的。故选A。

Doctors have successfully kept a heart beating in a container for 24 hours, bringing hope to thousands of patients across the world in need of a life-saving transplant.
1 However, the "game-changing" device can preserve a heart up to six times longer than existing methods. It provides the heart with oxygen and vital nutrients, allowing more time to transport it.
The device, named ULiSSES, fits into a carry-on box, so hearts can be flown around the world. 2 And it is expected to cost under $ 100,000. University of Texas researchers have successfully tested on pig hearts, which are similar to ours. 3
Dr. Rafael Veraza presented the findings on pig hearts at the annual meeting of the American Association for the Advancement of Science in Seattle.
" 4 Many years later, it is done much the same way," Dr. Veraza said. "Donated hearts generally remain viable (可存活的) for around four hours using traditional preservation methods. 5 Being able to keep a heart viable for 24 hours means you could transport it almost anywhere in the world, and this could save many lives."
A.It is expected to come into use soon.
B.The extra time could bring more hope to patients.
C.Usually, a donated heart can only last about four hours.
D.It works without being affected by temperature or air pressure.
E.The pig hearts remained viable for 24 hours after they were removed.
F.The first heart was transported more than 50 years ago by putting it on ice.
G.They plan to test it on human hearts in three months and put it on the market within a year.

阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
Last Friday, doctors at the University of Maryland Medical Center successfully replaced 1 heart of a very sick man with a specially-grown pig’s heart. It is the first time that doctors 2 (do) this surgery by now. After three days, the patient appears to be doing very well. Dr. Bartley Griffith who is the first surgeon 3 ( perform ) the operation, said this had never been done before. David Bennett, 57, is the man offered the heart. He was given special 4 (permit) to have the unusual operation because without it, he would have died.
Transplants (移植) usually come from people who have died, but want 5 (they) organs to be used to help other people live. There are far 6 (large) numbers of patients who need organs than those of organs. Over 3,800 Americans got heart transplants last year. But there are 7 (rough) 110,000 people who are waiting for some kind of transplant. For years, scientists have tried to figure out 8 they transplant organs from other animals into humans. This is hard because the human body almost always rejects something that isn’t its own.
Muhammad is one of the 9 (doctor) who helped perform the surgery. He’s been working to develop methods to help prevent pig organs 10 being rejected in humans. Doctors are watching Mr. Bennett’s recovery.
