A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern（模式）and sends it to a computer program. The program then checks to see if the pattern matches the right user. If not, an alarm sounds, and the computer locks the typist out. It locks out everyone else, even if the person knows the password. What's more, this equipment needs no batteries. It collects all the energy it needs from your actions of typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.
The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires（纳米线）on their surface area, increasing the effective contact areas between the plastics and fingers. This guarantees that there's enough power to run the keyboard as someone types.
Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of equipment. "It could also be applied to a touch screen, for example, "Dai says. " Then smart phones and notepads could collect energy from someone's actions of typing or drawing. "
"Future work might make the keyboard even more useful, "Dai adds. " A later design might build tiny capacitors onto the nanowires, "he suggests. Capacitors are little devices that temporarily store electric charge. Those might then be LEDs to light a keyboard in the dark.
Zhonglin Wang is a co-designer of the new keyboard. His team has built a working model of the keyboard. "If a company decides to fund（资助）its production, this keyboard could be in stores in as few as two years, "says Wang.
1.How does the new keyboard tell whether you are its owner？
A.By matching the typing pattern to the right user.

In my second-to-last semester of college. my favorite professor announced that he would be teaching a study abroad course over the winter break in Cambodia. The more he talked about the opportunity. the more interested I became. I left class thinking I might actually do it.
My immediate excitement gave in to excuses as the weeks passed. The trip would be expensive, I would have less time to spend with my family over the break, and I hadn't really traveled before. Most of all, I was terrified of taking the risk.
On the day when I made my decision, I suddenly felt as if I had finally opened my eyes and seen myself clearly. Why was I so scared to take this chance? I had moved away from home, had almost graduated from college, and had overcome plenty of small-scale fears. How could I let fear get in the way of a once-in-a-lifetime opportunity? Besides, I had always dreamed of traveling around the world and studying abroad was a major point on my list.
So took the challenge. I was scared but excited on the plane, and my fears faded as soon as the wheels touched the runway. I soon found myself attracted by ancient mountaintop temples. I spent my days teaching poor orphans(孤儿) simple English, learned little Khmer myself, and became an expert at avoiding terrible traffic and bargaining with Cambodian store owners.
By the end of my stay, I had fallen in love with travel, exploration and life of daily wonders.
My experience in Cambodia was incredible and life-changing. I came back and became a different person, but a better one: a better friend, sister, daughter, girlfriend and student. I came back and became a grown woman instead of a young girl.
After Cambodia, my life clicked into place. Before the trip, I hadn't known what I wanted to do after graduation. Now am planning on teaching English abroad as a volunteer. I am still amazed by my experience and thankful for everything it taught me. I now have a passion for overcoming fears, big or small, and have new faith in myself.

Along with soccer, basketball is a global sport. As you read this. young people somewhere in the world are happily passing, dribbling(运球) and shooting. It’s enormous fun and a joyful way to spend time with others.
Basketball is a game for everyone. Unlike golf or tennis. it doesn't require great wealth or a lot of space to play. After all, not many people have a golf course-sized backyard. and tennis equipment is expensive. Basketball, by contrast, just needs a wall with a hoop and a ball.
So after its invention by Canadian-American physical educator James Naismith in 1891, the sport took off within US citizens, who quickly became attracted to the game because it suited their circumstances. Today, 127 years later, basketball remains one of the most popular sports in the US, and the National Basketball Association (NBA)has an increasing appeal for fans around the world.
The success of basketball as global phenomenon is undoubtedly related to the way African-Americans play the game.” The basketball court reflected some of the major cultural shifts in America, such as from forbidding African-Americans to play basketball to allowing them to play in the NBA, "the LIVESTRONG website noted.
From the 1950s onwards, segregation rules, which had prohibited African-Americans from playing basketball in NBA games, were no longer used in the US. In 1950, when Earl Lloyd started to play for the Washington Capitols, things began to change. Since then, most of the greats of the game have been African-Americans, like Michael Jordan, Magic Johnson, Kobe Bryant and LeBron James.
It's not difficult to see that there's a strong link between political liberation and basketball. Something of this is expressed in a quote from the US author John Edgar Wideman. He makes a connection between basketball and hope:" When it's' played the way it's supposed to be played. basketball happens in the air; flying, floating, raised above the floor, letting the oppressed(受压制的) people of this earth imagine themselves in their dreams.”

In 2013, the carpenter from Schuby, Germany was surfing the Internet when he came across an organization called Be The Match, the largest bone marrow(骨髓)registry in the world. The 19-year-old didn’t think twice about donating, but he never found out who his marrow went to until years later when he received a message from halfway around the world。.
As it turns out. Dennis didn't just save another person. He saved a baby—little Gabriel Smith from Springfield, Illinois. As a little baby, Gabriel was diagnosed(诊断)with aplastic anemia and went into bone marrow failure. At just 14 months old, he received Dennis1 lifesaving transplant.
Fast forward to 20l8, when the Make — A — Wish Foundation contacted Gabriel's family to offer the seven-year-old one wish. "At first, he said, "Take my donor to meet Mickey," Gabriel's mom, Lauren, told CNN. "But we couldn't do that, so he was asked to choose one: Meet your donor or go to Disney. He chose to meet his donor, Dennis, without any hesitation."
Fortunately, Dennis had already agreed to share his identity with his recipient's family. Even so, hearing from them came as a bit of a shock. "I was speechless, Dennis said. "I can't believe that this happened and that he survived the bone marrow transplant." In August, Make — A — Wish arranged for Dennis to travel to the U.S. for the first time ever, where he and Gabriel became conjoined.
While Gabriel didn't go to Disney World, he got something even better: adventures with his own personal hero. "He is part of our family now," Lauren said. "We are hoping this experience will inspire others.”
And incredibly, it did! On August 27, Lauren shared on Facebook that Dennis and Gabriel's story has already inspired thousands of Americans to sign up with Be The Match. With one selfless choice, Dennis sparked a wave of potentially lifesaving acts. He's not just a hero to Gabriel and his family: He's a hero to us all.

The world we live in is becoming increasingly complex and uncertain. And with it, the conventional thinking of yesterday is no longer sufficient. Creating real breakthrough opportunities requires a fundamental change in our thinking. As Einstein said, "We can't solve problems by using the same kind of thinking we used when we created them.”
There's no better example of this than the myth of the four-minute mile.
For centuries, runners had been attempting to run a mile in under four minutes. In the 1950s, the attempt to break the barrier took on renewed importance, and a number of famous runners publicly and unsuccessfully attempted the challenge. Many of the newspapers of the day began to question whether humans would ever be able to run a sub-four-minute mile. Then, in 1954, a man named Roger Bannister did the unthinkable. He broke through the imaginary barrier, running the mile in 3 minutes and 59.4 seconds. It was an amazing achievement.
But here's what's really interesting: it was only forty-six days later that another runner broke Bannister's record. And the following year, two new runners broke the four-minute mark in the same race. Dozens followed, and as of this writing, more than 1,400 runners have accomplished the goal, including one runner who ran two miles in less than eight minutes.
Did something change with respect to human body, track conditions, weather patterns, running shoes, or the human diet between the start of Bannister's race and the few years that followed? No. So what explains the sudden and dramatic explosion of athletic achievement?
The myth's unimaginable power over runners had lifted. What Bunnister had done was not just break the four — minute — mile barrier; he shattered(粉碎)the myth that created the barrier in the first place. This paradigm (榜样)had offered a set of actions available for runners to take. Runners were really free to run through the invented boundary.
Creating breakthroughs requires shattering the myths that limit our imagination and lock us into conventional thinking. Think about your own situation. What myths are you stuck in? And what would be possible if you had the courage to challenge the myths?
1.What is needed to create breakthroughs?
A.Conventional thinking. B.Changes in our thinking.
C.Complex situation. D.Einstein's encouragement.
2.What was the real barrier that kept runners succeeding in the four-minute mile?
A.The belief that it was unachievable.
B.Lack of professional training.
C.The poor track conditions.
D.Lack of sufficient diet.
3.The example of Roger Bannister is used to .
A.list a new record in the race B.prove newspapers are wrong
C.show barrier can be broken D.call on us to learn from him
4.What does the writer try to explain in Paragraph 6?
A.The power of the myth.
B.The achievements of Bannister.
C.The importance of running freely.
D.The significance of breaking barriers.
5.What is the best title of the passage?
A.Creating Breakthroughs B.Accepting the Myths
C.Locking Your Imagination D.Becoming the Best Athlete
