B  [2015*四川遂宁高三第二次诊断] Researchers are now using 3-D printing to create models of the human heart to help heart specialists. The heart doc?tors can use the models to better help patients before an oper?ation.

Dr Bramlet, a children's heart expert at the University of Illinois College of Medicine, says the 3-D models show infor?mation 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 we can actually hold it in our 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 lay?er. Dr Bramlet says the model matches the real heart in eveVy detail. "When we're done with the model and made our deci?sion, 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 de?fects 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 Centre 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 opera?tion 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.

The other day I was watching SportsCentre when one of those "human interest" stories came on and really caught my attention.

The hero was about a 27-year-old professional Bass Fisherman named Clay Dyer. At first, they played it off as another guy trying to make the cut on the Bassmaster tour until they showed a picture of him. No legs, no arm, or rather, he has only 1/3 of his right arm. That's all that he has.

It was such an amazing story that I was wondering what this guy could do. Growing up, he learned to play-baseball and basketball, but found that fishing was his true calling. And he does it all on his own. He holds the fishing pole under his chin and uses that and his stub (残端)arm to cast and reel the fish in. He uses his teeth to help him unhook fish. He ties his own hooks on with his mouth, never really asking anyone else to help. Clay Dyer even knows how to swim. Since his body can't produce enough sweat on its own, he has to take a dip in the lake every few hours to keep cool. He dives in just like anyone else, then somehow treads water(採7jO with his stub arm, then, with a little help, pulls himself back up into the boat and goes on fishing.

Clay Dyer has never looked for others' pity, and nor has he allowed his physical disabilities to prevent him from becoming a professional fisherman. His motto for life is "If I can, you can. ,, He refuses to use special equipment, saying, "I want to do it with one hand the way they do it with two."

5.    Why did the author become interested in Clay Dyer?

A.    He assumed Dyer was living happily.

B.    He thought that Dyer could do nothing.

C.    He took great pity on this disabled man.

D.    He wanted to know what Dyer could do.

6.    We learn from the last paragraph that   .

A.    it seems easy for Clay Dyer to go fishing

B.    Dyer aims to behave like a normal person

C.    special equipment is allowed when fishing

D.    physical disabilities destroy his faith in life

7.    Which word best describes Clay Dyer's personality?

A. Diligent.    B. Faithful.

C. Inspiring.   D. Stubborn.

8.    The text is intended to .

A.    persuade readers to watch SportsCentre

B.    share Clay Dyer's life story with readers

C.    call on readers to care for the disabled man

D.    express the author's admiration for Clay Dyer

First Lady Michelle Obama is a big fan of volunteering. Volunteering means working for free to help someone else. Mrs Obama says volunteering is very important. "It should be part of everyone's life," she says.

Many teenagers agree. They say that helping others makes them feel great and makes a difference. These days, more teenagers volunteer than work for pay. Teenagers clean up parks? walk dogs at animal shelters, visit the elderly and more.

Some cities―including Seattle, Chicago, and Washington D. C. ―require high school students to volunteer. Students must volunteer in order to gradu?ate. The student volunteers learn new skills and help their communities.

Many parents are in favour of the idea―they say volunteering helps teen?agers build job skills. But most teenagers don't want to be forced to volunteer. They say they are busy. And they say volunteering is only fun if it's a choice.

Read both sides of the debate and decide.

YES

Volunteering can help teenagers get into college or get a job.

Many cities and towns need help. Volunteers can help keep important programmes going.

Not all teenagers will volunteer if it isn't required. Schools should require students to do all they can to get ready for adult life.

NO

Most teenagers are already very busy with classes, homework, jobs and sports. Forcing them to do more isn't fair.

It should be up to each person. Helping out doesn't feel as good if you have to do it.

Finding a volunteer job isn't always easy. Students shouldn't be kept from graduating because of something they can't control.

 A.    introduce the topic of the text
