Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants. However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel’s Tel Aviv University printed a 3D human heart on April 15.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” professor Tal Dvir told CNN. Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels, chambers and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb. And, although it can contract like a muscle, it cannot pump out blood like a real one. At present, the heart prototype is like a tiny airplane that has all of the right parts, but can’t fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue into human heart tissue with stem cell technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection. “Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized for every patient.”
But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice. “Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely,” Dvir said.
1.Why do scientists have to do further research before fitting the 3D-printed heart into the body?
A.Because the heart is incomplete.
B.Because the heart can’t pump out blood.
C.Because the heart is an airplane that can’t fly.
D.Because the heart can’t contract like a muscle.
2.What can we infer from the last two paragraphs?
A.The needed heart will be printed to meet every patient’s need.
B.The 3D printing of organs will be an unusual medical practice.
C.Dvir has a negative attitude towards the future of organ printers.
D.Patients will need medicines to stop their rejection for their heart transplant.
3.What can serve as the best title for the passage?
A.Organ printers in the hospitals.
B.How to get a suitable heart donation.
C.Heart disease: one of the major killers.
D.A 3D-printed heart: new hope for heart disease sufferers.

Like many languages spoken by people, Ayapaneco is dying. Only two people in the world still speak it, and they won't talk to each other.
Spoken in Mexico for centuries, Ayapaneco is one of 68 surviving languages in the mainly Spanish-speaking nation. The two speakers are Manuel Segovia and Isidro Velazquez. Though they live only 500 meters from each other in the village, the two men seldom talk to each other. Daniel, an American expert, who is working to make a dictionary of Ayapaneco, says the two men “don’t have a lot in common,” and that Segovia can be “active” while Velasquez tends to mind his own business and stay at home.
While Segovia still speaks to his wife and son in Ayapaneco, neither of them can manage more than a few words. Velasquez hardly speaks his native tongue any more. Daniel is working to preserve the language in dictionary form before its last surviving speakers pass away. According to Daniel, Ayapaneco and the other languages began dying out with the introduction of public Spanish education in the mid-20th century. For decades, local children weren’t allowed to speak anything else. Many people to cities, starting in the 1970s, also helped the dying out of native languages.
Ayapaneco is the name given to the language; Segovia and Velazquez call it “Nuumte Oote”, which means “true voice”. Neither man, however, speaks the same language. The dictionary will contain two versions(版本) of the language when it comes out later this year. Those behind the dictionary aren’t the only ones trying to save Ayapaneco. The National Language Institute plans to hold classes so that Segovia and Velasquez can pass on what they know to children.
It is thought that there are about 6,000 languages spoken on earth and that about half will disappear over the next 100 years. Let’s hope the “true voice” isn’t one of them.
1.Segovia and Velasquez seldom talk to each other in Ayapaneco because they___________________.
A．both dislike the language
B．don’t get along well with each other
C．are too busy to talk to each other
D．don’t share the same interests
2.Which are the main reasons why the language Ayapaneco started dying out?
a. No teacher liked to teach it. b. Local children had to speak Spanish.
c. many villagers went to live in cities. d. The surviving speakers didn’t like to use it.
A．a, b B．a, c C．b, d D．b, c
3.How does the National Language Institute try to save Ayapaneco?
A．Write a dictionary of Ayapaneco.
B．Let Ayapaneco be taught at school.
C．Introduce a public Ayapaneco education.
D．Ask villagers to speak Ayapaneco.
4.From the text we learn that the author____________________.
A．agrees that it is natural that Ayapaneco should die out
B．thinks Daniel’s effort to preserve Ayapaneco won’t work
C．thinks highly of Ayapaneco and wants people to learn it
D．hopes that Ayapaneco will not die out in the future
