Chris Mazdzer won a silver medal in a men’s luge (无舵雪橇) singles event at 2018 Pyeongchang Winter Olympics, South Korea — equaling the best finish ever for any member of the US Olympic luge team. In the luge, competitors lie flat, feet first, on a small sled (雪橇). They can travel around an icy track at speeds up to 140 kilometers an hour. The riders control the sled’s speed by changing the position of their feet or by moving their shoulders.
So why did the US luge team win a medal at the Pyeongchang Olympics? Most credit must go to Chris Mazdzer himself. The American said his win was a product of 16 years of preparation and intense training. But another reason for Mazdzer’s success could have been the 3-D printing technology, which his team used to make its equipment.
The term 3-D is short for three dimensional, meaning an object with length, width and height. In 3-D printing, 3-D models are first created as files, or documents, on a computer. The printer then uses a substance (物质) like plastic or metal to create physical objects. The process involves making one layer of material at a time until the objects reach full form.
The US luge team worked with an American company called Stratasys on the designing and manufacturing process for the sleds. First, the company made a scan, or image, of the body of every member of the luge team. Then, 3-D printing technology was used to create tools for making molds (模子) in the shape of Olympians on top of a sled. The process of designing and tooling sled parts is highly complex and can take several weeks. Officials from the US luge team say 3-D printing can greatly simplify the process, speeding up the production of parts.
Jon Owen, says the use of 3-D printing has made the team more competitive. It helps the team “continuously adjust designs and run the sleds on the track much faster than traditional processes,” he said. He added that the technology also provides a way to perfectly fit each rider to the sled, while cutting production time and costs.
1.According to the author, what mainly contributed to Mazdzer’s winning the medal?
A.His own great efforts. B.His using a new technique.
C.The cooperation with his luge team. D.The US Olympic luge team’s encouragement.
2.To make the sleds for the team, what did the company have to do?
A.To create tools for making sled parts.
B.To take some photos of the members first.
C.To create molds according to the members’ bodies.
D.To ask the Olympians to be present for several weeks.
3.From the last paragraph we learn that 3-D printing most probably __________.
A.saves plenty of competitors’ training time
B.helps competitors achieve their full potential
C.requires great skills of riders to fit the track
D.allows riders to change their sleds continuously
4.What is the text mainly about?
A.How 3-D printing usually works.
B.How we take advantage of 3-D printing.
C.How the US luge team performed this year.
D.How 3-D printing helped Team US go for gold.

A young female athlete in the Philippines recently won multiple gold medals for her school during a provincial sports despite not having proper running shoes.
Rhea Ballos, an 11-year old student of Salvacion Elementary School in Balasan, Iloilo, was only wearing bandages around her feet when she competed at the Iloilo Schools Sports Meet.
Facebook user Valenzuela posted images of the girl with her feet wrapped in brown plaster (石膏) bandages bearing the famous Nike logo. Ballos even wrote the word "NIKE" on the sides of her "shoes" to complete the "Nike running shoes" look. The bandages were tightly wrapped around her feet, creating a thin protective layer against the track.
While she was virtually (实质上) barefoot during the races, she was still able to defeat her opponents (对手) who all wore proper footwear intended for running. According to the post, Ballos bagged the top awards in the 400-meter dash, the 800-meter run, and the 1500-meter run in the inter-school sporting event held in Iloil, central Philippines.
When images of her "Nike" footwear were spread widely, Filipinos on social media showered her with praises for her dedication and character. Many noted that instead of wallowing in self-pity. she was even able to make light of the situation by drawing the Nike logo on her "running shoes."
Some of the commenters of Valenzuela's post expressed how the girl deserved to be recognized by Nike and that the brand should actually give her a new pair of real Nike shoes. It did not take long for Jeffery Cariaso, a famous coach, to take notice of Ballos' outstanding performance. He immediately made an effort to get in touch with the young track runner to help her.
