Quicker and faster 3-D printers have allowed not just amazing objects to be created, but have started to affect how doctors treat patients.

We’ve put together a list of some of the most amazing medical breakthroughs made possible with 3-D printing.

Life-Saving Airway

In 2013, doctors created a new airway for kaiba Gionfriddo, a boy born with an airway that kept collapsing (萎陷). To save his life doctors printed tiny tubes to join together in different shapes and sizes until one finally worked for Kaiba. It was placed in Kaiba’s bronchus (支气管) so that it no longer collapsed. Even more remarkably, once the plant was placed it could stay there. It’s designed to eventually be absorbed into the body.

New “Bionic” Hands

One of the most remarkable ways 3-D printing is now being used is as a way to create prosthetics (假肢). A boy born without an arm named Alex was able to get a new“bionic”hand thanks to it. Last year a college student spent 8 weeks coming up with a special prosthetic design that only cost a few hundred dollars in materials. He said he wanted to create a prosthetic far cheaper than other choices that can run tens of thousands of dollars.

A practice Heart

In Seattle, doctors have been able to use 3-D printing technology to“practice”risky operations so that they will face fewer surprises in the operating room. Kami Sutton was born with her heart“in the wrong place”. For a recent operation her doctor was able to take many scans of Sutton’ s heart and print out a model. “Kami’s heart is truly one-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operating on her without understanding the structure of her heart better could be very dangerous.”

A New Skull

A U.K. man was able to have part of his skull rebuilt thanks to a 3-D printer. Stephen Power broke his cheek bones in a crash. To help Power his doctors instead created 3-D bones all carefully printed in the shape of his face. “This is really the first time we’ve taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly,”said Adrian Sugar, a doctor.

1.What is special about the 3-D printed airway?

A.It uses high-tech materials.

B.It varies in shapes and sizes.

C.It can be absorbed by the body.

D.It can prevent any disease in the airway.

2.What is the advantage of the new“bionic”hand?

A.Its price. B.Its effects.

C.Its materials. D.Its shape design.

3.How can 3-D printing technology help doctors in the operating room?

A.It helps them get better scans.

B.It guarantees the success of operations.

C.It enables them to practice and learn more.

D.It helps them to deal with patents, anxiety.

4.What does Adrian Sugar think of the new skull printed by 3-D technology?

A.He has doubts about it.

B.He thinks highly of it.

C.It needs to be better planned.

D.It functions well but needs improving.

When it comes to cultural heritage protection, the Grand Canal of China is probably the world’s greatest project of its kind. The big inland waterway system in the north-eastern and central eastern plains passes through eight of the country’s present-day provinces.

The Canal runs from Beijing in the north to Zhejiang Province in the south. Constructed in sections from the 5th century BC onwards, it was designed as a means of communication in the 7th century AD. The Canal is the world’s greatest civil engineering project before the Industrial Revolution.

The Grand Canal reached a peak in the 13th century, providing an inland navigation(航行) network consisting of more than 2,000 kilometers of artificial waterways, linking five of the most important river basins in China, including the Yellow River and the Yangtze. It entered a bid as a UNESCO(联合国教科文组织) cultural heritage site in 2008.

The Grand Canal cultural square is located in Beijing’s Tongzhou district. Ever since the Yuan dynasty 800 years ago, the Tongzhou section of the Grand Canal has been the life blood of Beijing. Grain and building materials were all transported to meet the endless demands of the big cities. Even today, the Grand Canal plays a major role in the lives of its citizens.

"I grew up near the Grand Canal. In the past the waterway was a lot narrower, but now it’s nice and wide and bridges are built over it. I think if the bid for world heritage status succeeds, it will greatly make Tongzhou more famous in the world, especially with Tongzhou aiming to be a sub-center of the capital Beijing," a citizen said.

The result of the bid is set to be released next week, and no doubt it will certainly make it into the history books if the Canal is listed as a world heritage site.

1.It can be concluded from the passage that ________ .

A. The bid’s result of the Canal will be announced soon

B. the Canal is the UNESCO’s newest world heritage site

C. the Canal is to connect Tongzhou with Zhejiang Province

D. the Canal will be a bid for a UNESCO cultural heritage site

2.The Grand Canal was in the most glorious time ________ .

A. when it was aimed as a means of communication

B. when it crossed the Yellow River and the Yangtze

C. when it was born about six hundred years later

D. when it was designed as an artificial waterway

3.What can we infer by reading the passage?

A. Tongzhou used to be the capital of the Yuan dynasty.

B. Most citizens living in Tongzhou depend on the Canal.

C. Tongzhou will benefit if the Canal is made a heritage site.

D. Some citizens think the Canal not to be a cultural heritage item.

Where do dogs come from?

Gray wolves are their ancestors. Scientists are pretty consistent about that. And researchers have suggested that dogs’ origins can date back to Europe, the Near East, Siberia and South China. Central Asia is the newest and best candidate, according to a large study of dogs from around the world.

Laura M. Shannon and Adam R. Boyko at Cornell University, and an international group of other scientists, studied not only purebred(纯种的) dogs, but also street or village dogs.

Dr. Shannon analyzed three different kinds of DNA, Dr. Boyko said, the first time this has been done for such a large and diverse group of dogs from 38 countries. And that led them to Central Asia as the place of origin for dogs in much the same way that genetic studies have located the origin of modern humans in East Africa.

The analysis, Dr. Boyko said, pointed to Central Asia, as the place where “all the dogs alive today” come from. The data did not allow precise dating of the origin, he said, but showed it occurred at least 15,000 years ago.

Greger Larson of Oxford University, who is leading a large international effort to analyze ancient DNA from fossilized bones, said he was impressed by the study. “It’s really great to see not just the number of street dogs, but also the geographic breadth and the number of remote locations where the dogs were sampled,” he said in an email. He also praised the sampling of different kinds of DNA and the analytic methods.

Dr. Larson, who was not involved with the study, said he thought the Central Asia finding required further testing. He said he suspected that the origins of modern dogs were “extremely messy” and that no amount of sampling of living populations will be definitive. He said a combination of studies of modern and ancient DNA is necessary.

1.According to the research on a large number of dogs, we can know____________.

A. dogs mainly lived in Europe and the Far East

B. dogs would like to live in Central Asia

C. dogs’ ancestors come from gray wolves

D. the Near East has many gray wolves

2.What can we infer from what Dr. Boyko said?

A. There are three different kinds of DNA in dogs.

B. This is the second time they have done so many dogs.

C. They only do research on village dogs from many countries.

D. Modern humans are from East Africa while dogs come from Central Asia.

3.Greger Larson got a very deep impression of his study because he____________.

A. found the study based on many different dogs and the sample dogs’ remote locations

B. saw the number of street dogs from fossilized bones

C. watched the geographic breadth of the sampled dogs

D. praised his teammates for their hard work on the dogs

4.Who wasn’t engaged in the study of dogs’ origins?

A. Laura M. Shannon B. Adam R. Boyko

C. Shannon and Boyko D. Greger Larson

Such chronic (慢性的) diseases as heart disease, stroke, cancer and lung disorders are the most leading causes of death in the world. Yet health experts say these conditions are often the most preventable.

The World Health Organization (WHO) points out chronic diseases lead to about 17 million early deaths each year. The United Nations (UN) agency expects more than 380 million people to die of chronic diseases by 2015. About 80% of the deaths will happen in developing nations.

Chronic diseases now cause two-thirds of all deaths in the Asia-Pacific area. In ten years it could be almost three-fourths. People are getting sick in their most economically productive years. In fact, chronic diseases are killing more middle-aged people in poorer countries than in richer ones. The WHO estimates (估计) that chronic diseases will cost China alone more than 500,000 million dollars in the next ten years. That estimate represents the costs of medical treatment and lost productivity. Russia and India are also expected to face huge economic losses.

According to a WHO report, deaths from chronic diseases have increased largely as the result of economic gains in many countries. Until recently infectious and parasitic (寄生的) diseases have been the main killers in Asia and the Pacific but they are no longer the major cause of death in most countries.

As many as 80% of the deaths from chronic diseases could be prevented, health officials say. An important tool for governments is to limit the marketing of alcohol and tobacco to young people. Also, more programs are needed to urge healthy eating and more physical activity.

The UN aims to reduce chronic-disease deaths by 2% each year by international action through 2015, that’s to say, 36 million lives could be saved, including 25 million in Asia and the Pacific.

1.According to the passage, chronic diseases ________.

A. can be ignored B. can be prevented

C. will disappear D. are all deadly

2.In many countries, what’s mainly responsible for increasing deaths from chronic diseases?

A. The economic development.

B. The poor living conditions.

C. Infectious and parasitic diseases.

D. Young people’s bad habits.

3.Which of the following statements is NOT true?

A. Most deaths are caused by chronic diseases in the world.

B. The middle-aged are becoming victims of chronic diseases in Asia.

C. Infectious and parasitic diseases are no longer death killers.

D. To reduce chronic-disease deaths needs worldwide efforts.

4.The best title for the passage would be “________”.

A. Different Measures to Fight Chronic Diseases

B. The WHO’s Report on Heath in Developing Countries

C. The UN: the Leader of International Community

D. Chronic Diseases: the World’s Leading Killer
