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."

Having learned much about the War of Resistance against Japan, Mao Jingxin didn’t like the Japanese when she was a child. “I thought they were cruel and rude,” said the 18-year-old girl from Hebei Province. But she began to change her mind after she met some Japanese teenagers in a history museum six years ago. These fashionable high school students looked seriously at the history displays and talked to Mao in a friendly way. “I found that they are not bad as I thought,” she said.

Like Mao, many Chinese teenagers’ are caught up in this confusion. A survey by 21st Century Teens shows about 51 per cent of Chinese teenagers say they dislike Japan. But most of them still want to have a Japanese friend. Also, Japan lies third on their list of Asian countries that they want to visit, following Singapore and South Korea. Teens did a survey just before the 60th anniversary of the victory day of the War of Resistance against Japan, which fell on September 3. The survey aimed to encourage understanding and communication between young Chinese and Japanese.

Teens also wanted to understand Chinese teenagers’ attitudes towards Japan, and how much they actually know about the country. As Teens found, more than 60 per cent of Chinese teenagers learn about Japan through the media or books. Only 16 per cent have ever met a Japanese person.

“Most of my friends hate Japan for what it did to China during World War II. But people should not live in hatred. I think the best way to figure it out is to have contact with the Japanese people myself,” Zhang Yuyuan, a Senior 2 girl, told us in the survey.

Jin Xide, professor of the Chinese Academy of Social Science, says that China and Japan actually had a peaceful relationship during the 1970s and 1980s. Since the 1990s, the growth of Japan’ s right-wing forces has caused great difficulties. “We have to be strong against them. But we mustn’t ignore the fact that there are far more friendly Japanese,” added Jin.

“Japan has done wrong to Asian countries including China and it has caused pain to everyone,” said Hikaru, a 17-year-old girl in Kawasaki. Having visited China four times and learned much, she understands the importance of communication between the two peoples. She plans to join in an exchange programme with Chinese youth. “Welcome to Japan, my Chinese friends!” She says it with a smile.

64. Most teenagers hate Japanese because _______.

A. the Japanese they meet are cruel

B. the Japanese were cruel during the war

C. they look too fashionable

D. the Japanese don’t want to communicate with Chinese people

A. Only a small percentage of teenagers have met a Japanese.

B. More than half of the teenagers in the survey don’t like the Japanese.

C. Singapore is one of the most popular Asian tourist places for Chinese teenagers.

D. Most Chinese teenagers learn about Japan through exchange activities.

66. According to Professor Jin, _____ is the main reason for the worse relationship between Japan and China.

A. the War of Resistance against Japan

B. lack of communication

C. Japan’s increasing right-wing force

D. Japan’s rapidly-growing economy

67. The passage is written to ______.

C. provide information about Japanese teenagers

D. give a brief introduction to the history of the War of Resistance against Japan

In most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters（恶魔）.The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.?

Many teenagers like electronic games so much that they can't stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”.They develop pains on their fingers because of the constant pressure. They play and play so that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the wrist and arm become so inflamed and swollen(充血红肿)that they press against the bones. This condition is what doctors now call “Space Warriar's Wrist”.Other strange aches and pains also are likely to affect（影响）the elbows and shoulders.?

Another even more alarming problem is shown by the case of a 17-year-old girl which was recently in the British Medical Journal. She had been playing all kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(晕倒)and fell to the floor.?

Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.?

“Space Warrior's Wrist”is caused by_______.?

A. constantly pressing the buttons?

B. rapidly moving across the screen ?

C. tightly holding the joystick controls?

D. inflamed and swollen muscles of the wrist?

“Keep an eye on Esther. I’ll be back in a second,” Joy Warren said to her three-year-old son Stephen, who was sitting in the back of the Buick. She didn’t like leaving the children alone in the car, but the baby was sleeping soundly. And it would only be a moment.

She had hardly walked 40 yards when she saw the car moving. It headed straight towards the river. Unable to swim, Joy shouted, “My babies are in that car!”

Daniel Whitehead, a 17-year-old student, was walking by the river when the Buick crashed into the water just yards ahead .Without thinking, Daniel jumped in. Though a competitive swimmer, he was shocked by the icy chill.

Two minutes earlier, Skip Womack had pulled to a halt as the Buick ran in front of him. Now seeing it hit the water and hearing Joy’s cries, Skip got out of his truck and jumped into the water. He had only one thought: If I don’t get them out, they’ll drown.

Daniel reached the car and grabbed a door handle. But the water was only four inches beneath the window, and the door wouldn’t open. With one powerful punch, Daniel and Skip broke a window. Daniel reached inside and lifted Stephen out. He placed him on his back and set out for shore. At the same time, Skip squeezed himself through the window .He managed to free Esther from beneath her seat belt. After he got out of the car with the baby, he held her over the water and swam toward the shore. All this took place just seconds before the Buick disappeared beneath the water.

Later, driving home, Skip thought of his wife and children—how close he’d come to leaving them behind. He thought of the miracle he’d lived through, and how two children were still alive because he and Daniel happened to be in the right place at the right time.

Why did Joy leave her children in the car?

A. He did not like shopping with a child in hand.

B. She didn’t like waking up her baby.

C. Stephen was big enough to take care of his sister.

D. It was icy cold outside.

C. He freed him from his seatbelt before he got him out.

D. He held him over the water and swam back to shore.

What happened to Joy Warren’s Buick?

A. It had four inches of water in it.

B. One of its windows could not be opened.

C. It was pulled out of water and set on the shore.

A 17-year-old boy, caught sending text messages in class, was recently sent to the vice principal's office at Millwood High School in Halifax, Nova Scotia.

The vice principal, Steve Gallagher, told the boy he needed to focus on the teacher, not his cellphone. The boy listened politely and nodded, and that's when Mr. Gallagher noticed the student's fingers moving on his lap. He was texting while being scolded for texting!

"It was a subconscious act," said Mr. Gallagher, who took the phone away. "Yong people today are connected socially from the moment they open their eyes in the morning until they close their eyes at night. It's addictive. They can’t simply stop doing that."

Because so many people in their teens and early 20s are in this constant whir of socializing -- accessible to each other every minute of the day via cellphone, instant messaging and social-networking Web sites -- there are a host of new questions that need to be addressed in schools, in the workplace and at home. Chief among them: How much work can "hyper-socializing" students or employees really accomplish if they are holding multiple conversations with friends via text-messaging, or are obsessively checking Facebook? Almost a quarter of today's teens check Facebook more than 10 times a day, according to a 2009 survey by Common Sense Media, a non-profit group that monitors media's impact on families.

Will these young people get rid of this habit once they enter the work force, or will employers come to see texting and "social-network checking" as accepted parts of the workday?

"In past generations, students got in trouble for passing notes in class. Now students are adept at texting with their phones still in their pockets," said 40-year-old Mr. Gallagher, "and they're able to communicate with someone one floor down and three rows over. Students are just fundamentally different today. They will take suspensions rather than give up their phones."

When the boy was scolded for texting, _________________.

A. he was polite and regretful

B. he was trying sending another message

C. his fingers shouldn’t be put on his lap

D. he listened carefully and nodded

What does the underlined word “subconscious” mean?

A. dangerous B. purposeless C. popular D. impolite

What can we learn about the students in their teens and early 20s?

A. All of them are addicted to using cellphones.

B. They will get rid of the habit once they go to work.

C. They are greatly different from the past generations.

D. Most of them check Facebook more than 10 times a day.

What can we infer from the passage?

A. The employers will accept texting at workday.

B. The students will give up their phones one day.

C. It’s convenient for students to communicate with others with cellphones.

D. Facebook is a kind of book students need to read at school.
