【题目】Researchers are now using 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.

Dr. Bramlet, a children’s heart expert at the University of Illinois College of Medicine, says the 3-D models show information he cannot get any other way.

“And so what we’ve done with the printed models? We’ve pulled it out of the screen so that you can actually hold it in your hand and evaluate the anatomy（解剖）.”

A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model to understand the anatomy.

Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster（石膏）form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail. “When we’re done with the model and made our decision, we want to be able to go back to the source image and confirm those findings,” he says.

Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby’s heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.

Kathy Magliato is a heart surgeon at Saint John’s Health Center in Los Angeles. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients.

“I can then take this very complicated structure before the operation and I can hold it in my hand and plan an operation around what I’m seeing, touching and feeling. That to me is what can potentially change the game in an operation and save lives.”

Dr Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

【题目】Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device (装置) developed by doctors in Israel.

The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed (瘫痪) but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine.

With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs.

Ten healthy people easily mastered sniff—driving a wheelchair through a maze (迷宫), and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair.

At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study.

【1】What’s the purpose of the passage?

A. To introduce a new invention.

B. To equip the disabled with life skills.

C. To show the nose's special functions.

D. To instruct doctors to apply for a patent.

【2】In the test, the paralyzed people with normal intelligence can use their nose to ______.

A. type long sentences quickly

B. play computer games easily

C. enter a website without much difficulty

D. communicate with others successfully

【3】With the help of the sniffing device, a 30-year-old disabled man ______.

A. spent six years learning how to drive a wheelchair

B. failed to drive through the maze at his first attempt

C. took the wheelchair controlled by healthy participants

D. managed to drive an electric wheelchair by sniffing

【4】From the last paragraph, we can infer that the sniff-controlled technology ______.

A. will be applied to other fields of research

B. needs further developing to serve more people

C. has become an important patented invention

D. shows the wisdom and talents of Israel doctors
