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 Gionfriddjo,a boy bom 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 (支氣管) so that it no longer collapsed. Even more remarkably,once the plant was placed it could stay there. It's designed to eventualiy 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 bom 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 bom 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.
28. 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.
29. What is the advantage of the new “bionic”hand?
A. Its price. B. Its effects.
A. Its materials. D. Its shape design.
30. 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 patients,anxiety.
31. 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.

B
History tells us that footwear was one ot the first things ancient people learned to make. Footwear helped them across rocky paths or hot sands without injuring themselves. The earliest footwear we know of was simply a piece of plaited(編織的) grass or leather tied to the feet.
The ancient Egyptians seem to have inyented the first footwear with a firm sole(鞋底) 一 sandals. Egyptian royalty usually wore sandals that had a different style from those with lesser 
status (身份) , while slaves were not allowed to wear anything on their feet. The sandal is still the basic form of footwear in many countries, particularly those with a hot climate,whereas in cold climates,an entirely different type of shoe appeared — the moccasin — a slipper-shaped shoe made of soft but strong leather.
The Greeks were the first to develop shoes with heels (鞋跟) . Then,in the Middle Ages,shoes with long points at the toe became very chic for the nobilitv These shoes were often very difficult to wear. Other trends followed,with square-toed shoes,wide shoes,and even shoes that could make a woman stand two feet taller. Not surprisingly,these sometimes led to accidents. Even today,fashion rather than comfort often leads to the kind of shoes women wear.
Mechanical shoemaking appeared in the 1800s in North America. Until then,shoes had been made with the same kinds of hand tools used by the ancient Egyptians. And in 1858,a machine was invented that could stitch (縫合) the sole of a shoe to the upper part. Now it was possible to make shoes that were shaped to fit either the left or right foot. Toward the end of the 1800s came a new type of shoe that was specifically designed for sports — the sneaker — and it soon become an all-time favorite.
25. What did shoes often show in ancient times?
A. The rich resources.
B. People's different beliefs.
C. People's status in society.
D. The changeable climates.
26. What does the underlined word “chic” in Paragraph 3 probably mean?
A. Valuable. B. Convenient.
C. Fashionable. D. Comfortable.
27. Before mechanical shoemaking appeared.
A. shoes were often very difficult for people to wear
B. all the shoe patterns made by the Greeks were the same
C. the only function of footwear was to protect people，s feet
D. people wore the same-shaped shoes on their two feet
28. How does the text mainly develop?
A. By providing examples.
B. By making comparisons.
C. By following the order of time.
D. By following the order of importance.

Dear Sir,
I'm writing to complain about the advertisement for road safety presently being showing on television. I think the advertiser should be banned showing it.
Most people have seen an advertisement and are frightened by it. It really is in very bad taste. Who could ever forget that boy lying on the roads,with blood pour from his head? I simple don，t believe the advertisement will discourage people from driving fast.
I think the government should prevent any advertiser from using images which frightens people. There should be a law against so advertising methods. I hope we can be succeed in persuading advertisers to use less shocked advertisements.

B
Many doctors know the story of Mr Wright .In 1957 he was diagnosed(診斷) with cancer,and given only days to live. He heard that scientists had discovered a new medication, Krebiozen, which was effective against cancer and he begged the doctor to give it to him. His physician,Dr Philip West finally agreed. After Mr Wright had been given an injection on a Friday afternoon,the astonished doctor found his patient out of his “death bed”.
Two months later,Mr Wright read medical reports that the medication was fake. His condition immediately got worse again. “Don’t believe what you read in the papers,” the doctor told Mr Wright. Then he injected him with what he said was “a new super-refined double strength” version of the drug. Actually,there was no drug,just a mix of salt and water. Later,Mr Wright was the picture of health for another two months until he read an official report saying that Krebiozen was worthless. He died two days later.
This story has gone unnoticed by doctors for a long time and the idea that a patient's beliefs can make a disease go away has been thought of as too strange. But now scientists are discovering that the placebo effect(寬慰作用) is more powerful than anyone has ever thought. They are also beginning to discover how such unbelievable results are achieved. Through new techniques of brain imagery,it can be shown that a thought,a belief or a desire can cause chemical processes in the brain which can have powerful effects on the body. Scientists are learning that some body reactions are not caused by information coming into the brain from the outside world,but by what the brain expects to happen next.
Placebos are “l(fā)ies that heal”，said Dr Anne Harrington,a historian of science at Harvard University. “The word ‘placebo’ is Latin for ‘I shall please’ and it is typically a treatment that a doctor gives to anxious patients to please them,” she said. “It looks like medication,but has no healing ingredients whatsoever."”
25. After being injected Krebiozen for the first time,Mr Wright.
A. got cancer B. almost died
C. felt better D. gave up What caused
26. Mr Wright's death according to the story?
A. The fake drug.
B. His own beliefs.
C. His damaged brain.
D. The doctor's wrong diagnosis.
27. What's the purpose of Paragraph 3 ?
A. To explore the biology of human brains.
B. To explain why people get cancer.
C. To analyse how placebos work.
D. To question Mr Wright's story.
28. What does Dr Anne Harrington think of the placebo effect?
A. It is limited.
B. It is effective.
C. It can cheat patients.
D. It goes against science.
