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.

We looked through the Styles archive(档案文件) of 2015, sorting through the many tips and tricks throughout our stories. Our subjects are about what you wear, what you consume and how you love. 1.
1. Wear comfortable underwear.
“I only wear granny panties(内裤),” said Julia Baylis, 22. Mayan Toledano, 27, added: “What’s sexy for us is being natural and comfortable.” 2.
2. Stare into the eyes of someone you love (or want to love) for exactly four minutes.
Not two. Not three. Four. “ 3. ” said Mandy Len Catron, the author of a Modern Love column on the exercise. “Four really takes effect.”
3. Be nice to babies.
Even if they're screaming on a plane. Nyfesha Miller became a social media star after taking care of her seatmate's crying infant on a flight earlier this year.
4. 4.
It may be true that you can't really cure depression, so you can only get better at living with it. But raising a kitten(小猫)seemed to help one depressed man.
5. Make sure you are the boss of your electronic devices.
Rather than the other way around. 5. That’s the most important for us to keep the laws.
6. Enjoy the phrase 'I'm too old for this.'

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
