A 17--year--old girl won a scholarship worth $100,000 for building an inexpensive yet accurate spectrograph (声谱仪) that recognizes the "fingerprints" of different molecules(分子).
Mary Master man, a senior at West Moore High School in Oklahoma City, was named the winner Tuesday of the annual Intel Science Talent Search.
More than 1,700 high school seniors across the nation entered the competition, which is in its 66th year.
Spectrographs, which measure wave lengths, are used in research such as astronomy and medicine and in industry. For example, they can be used as a sensing equipment to look for explosives or drugs or to help determine how old an art work is through its powders.
They can cost as much as $100,000, but Masterman's invention--made of lenses, a laser, aluminum tubing and a camera--cost less than $1,000, Intel said.
Masterman received the honor from Intel Corp. Chairman Craig Barrett during a banquet Tuesday night in Washington.
"It was a complete surprise," Masterman said. "I wasn't expecting it."
Masterman said she has been interested in science ever since she was little. She couldn't remember ever not being interested. She credits her parents with encouraging her.
She said she has not decided where she will attend college but would eventually like to become a physicist or chemist.
Among the former winners of the competitions top award are six Nobel Laureates(佩戴桂冠的人), three National Medal of Science winners, 10 MacArthur Foundation Fellows and two Fields Medalists.
"You're not only dealing with the top young person in the science field in the country in Mary, but you're dealing with 40 finalists who are doing breaking--edge research in total," said Brenda Musilli, Intel's director of education. "It's really something that's hard to imagine, how a young person like Mary could even achieve this level of capability at such a young age."

查看习题详情和答案>>An eighteen-year-old high school student from Utah won the top prize in the Intel Science Talent Search in the United States. The winner received a computer and a scholarship for a college education.
More than 1,500 students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science—almost every area of science.
Forty students were invited to Washington, D.C．for the final judging. A group of scientists judged them on their research abilities, Critical thinking skills and creativity. The judges also questioned the students about scientific problems before deciding on the winners.
The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years. She found that people have a harmful effect on the river through human activity, including agriculture. And she suggested ways to improve the water quality in the future. These include educating the public not to put household chemicals down the drains（下水道）, which lead to the river eventually.
Seventeen-year-old Yi Sun of the Hanker School in San Jose, California, earned the second place. He won a 75,000 dollar scholarship for new discoveries about a mathematical theory known as random walks. His work could help computer scientists and chemists. Yi Sun was born in China.
The third-place winner was also seventeen and born in China. Yuan “Chelsea” Zhang of Montgomery Blair High School in Rockville, Maryland, won a 50,000 dollar scholarship. She researched the molecular genetics（分子遗传学）of heart disease. Her findings could aid the development of new medicines.

查看习题详情和答案>>CAIRO, Egypt (Reuters) April 24, 2006—Three explosions shook the Egyptian Sinai resort of Dahab on Monday, killing 23 people and wounding dozens of others, rescue and security officials said.
Witnesses said smoke billowed① up from the town’s tourist bazaar, and residents said they saw body parts and debris② on the street after an explosion at a restaurant.
People in the small beach and diving resort, which is popular with backpackers, described scenes of carnage③ and chaos④.
A cafe worker who was about 200 meters (yards) from the scene said: “We saw many dead people. People were screaming. People were being taken to hospital. Egyptians went to give blood. There were body parts. There’s police everywhere.”
“There are ambulances and cars taking people to hospital,” said another resident, who also did not want to be named.
The explosions took place at the Nelson Restaurant, the Aladdin Cafeteria and the Ghazala Supermarket, the Interior Ministry said.
The explosions took place in quick succession at about 7.15 p.m. (1715 GMT). “There is smoke coming from the area and there are people running everywhere,” said one witness, who heard the blasts.
An official with the local ambulance service said many of the dead appeared to be foreigners.
Israeli divers often stay in the resort but with the Passover holiday over it is unlikely many were there. The Israeli ambassador in Cairo and Israeli authorities said they did not know of any Israeli casualties⑤.
One visitor said police were stopping cars and buses leaving the resort and had imposed restrictions on movements in and out of backpacker camps in the area.
It was the third set of three explosions on the eastern coast of the Sinai peninsula since October 2004, when a group attacked the Hilton hotel in the border resort of Taba and two other resorts on the northeast coast, killing 34 people.
Notes:
① billow v. 翻腾

查看习题详情和答案>>Years ago, when I started looking for my first job, wise advisers advised, “Barbara, be enthusiastic（热情的）! Enthusiasm will take you further than any amount of experience.” How right they were!
“Nothing great was ever done without enthusiasm,” wrote Ralph Waldo Emerson. It is the paste（浆糊） that helps you hang in there when the things get tough. It is the inner voice that tells you, “I can do it!” when others shout, “No, you can’t!” It took years and years for the early work of Barbara McClintock, a geneticist who won the 1983 Nobel Prize in medicine, to be generally accepted. Yet she didn’t stop working on her experiments.
We are all born with wide-eyed, enthusiastic wonder and it is the childlike wonder that gives enthusiastic people such youthful air, whatever their age. At 90, cellist Pablo Casals would start his day by playing the cello（大提琴）. As the music flowed through his fingers, his shoulders would straighten and joy would reappear in his eyes. As writer and poet Samuel Ullman once worte, “Years wrinkle(起皱纹) the skin, but to give up enthusiasm wrinkles the soul.”
Enthusiastic people also love what they do, not considering money or title or power. Patricia Mellratl, a retired director of the Missouri Rpertory Theater in Kansas City, was once asked where she got her enthusiasm. She replied, “My father, long ago, told me, ‘I never made any money until I stopped working for it.’”
We can’t afford to waste tears on “might-have-been”. We need to turn the tears into sweat as we go after “what-can-be”. We need to live each moment whole-heartedly, with all our senses finding pleasure in the sweet of a backyard garden, the simple picture of a six-year-old, and the beauty of a rainbow.
What is the passage mainly talking about?
A. Enthusiasm is more important than experience.
B. Enthusiasm can give people more success and fame
C. Enthusiastic people will never get old
D. Enthusiasm can make you succeed and enjoy life.
We can infer that enthusiasm is more important for a person especially when __________.
A. he is in trouble B. he is getting old
C. he can do what he love D. he has succeeded
The author mentions Pablo Casals in the third paragraph to show that ______.
A. enthusiasm can make people feel young
B. music can arouse people’s enthusiasm
C. enthusiasm can give people inspiration needed to succeed
D. enthusiasm can keep people healthy
How many examples are referred in the passage to show the importance of enthusiasm?
A. Three B. Four C. Five D. Six
Which proverb(谚语) may the writer agree with according to the last paragraph?
A. A good beginning makes a good ending
B. Don’t cry over the spoiled milk
C. Love me, love my dog
D. All work and no play makes Jack a dull boy
