1 . In Washington DC, at a Metro Station, on a cold January morning in 2007, a man with a violin played six Bach pieces for about 45 minutes. During that time, approximately 2000 people went through the _________, most of them on their way to _________.

About four minutes later, the violinist received his first _________. A woman threw money in the hat and, without stopping, continued to walk. At six minutes, a young man leaned _________ the wall to listen to him, then looked at his watch and started to walk again. At ten minutes, a three-year old boy stopped, but his mother pulled him along_________. The kid stopped to look at the violinist again, but the _________ pushed hard and the child continued to walk,_________ his head the whole time.

At forty-five minutes, the musician played continuously. Only six people stopped and listened for a short while. About twenty gave money but continued to walk at their normal _________. The man collected a total of $32.

After one hour, he finished playing and silence _________. No one noticed and no one applauded. There was no __________ at all.

No one knew this, but the violinist was Joshua Bell, one of the greatest musicians in the world. He played one of the most __________ pieces ever written, with a violin worth $3.5 million dollars. Two days before, Joshua Bell sold out a __________ in Boston where the seats averaged $100 each to sit and listen to him play the same music.

In a common-place environment, at an __________ hour, do we perceive beauty?

If so, do we stop to __________ it? If we do not have a moment to stop and listen to one of the best musicians in the world, playing some of the finest music ever written, with one of the most beautiful instruments ever made... How many other things are we missing as we __________ through life?

5 . I was cycling and noticed a person, about a quarter of a kilometer in front of me. I could tell he was cycling a little slower than me and decided to try to _________ him. I had about a kilometer to go on the road _________ turning off.

So I started cycling faster and faster and every _________ I was gaining on him just a little bit. After just a few minutes I was only about 100 yards behind him, so I really picked up the pace and _________ myself. You would have _________ I was cycling in the last section of London Olympic triathlon.

_________, I caught up with him and passed him by. On the inside I felt so good. I beat him, of course, but he didn't even know we were _________.

After I passed him, I _________ that I had been so focused on competing against him that I had _________ my turn. I had gone nearly six blocks past it and had to turn around and go all the way back.

Isn't that what happens in life when we __________ competing with co-workers, neighbors, and friends, trying to prove that we are more successful or more important? We spend our time and __________ chasing after them and we miss out on our own __________ to our future.

The problem of unhealthy competition is that it's a never-ending __________, because there will __________ be somebody ahead of you, someone with a better job, more money and more education, etc.

Therefore, just take what life has given you, your height, weight and personality. Stay focused and live a healthy life. There's no __________ in life. Run your own race and wish others well.

7 . Rhemy Elsey, a fifth-grader, is deaf and mainly uses sign language to communicate, along with the _________ of an interpreter. Some of his fellow fifth-graders decided to _________ their break once a week to form an American Sign Language club in order to chat more _________with Rhemy.

It’s been a few months since the club was _________ and his classmates’ participation makes Rhemy _________. “It’s like they want to be like me” he said.

His interpreter, Tammy Arvin, _________ the club, which meets every Wednesday. So far, the club members have learned basic _________ in different topics including school, food and clothing. Arvin said that _________ the club’s formation, it was difficult for students to communicate directly with Rhemy. So when the other students expressed interest in an ASL club, Arvin was _________.

The club has already had an effect on the way the students ____________ with Rhemy. The ____________ can have more natural conversations which make Rhemy feel less isolated(孤立的). And the students are also ____________ a very important culture.

“It ____________ gives them a perspective on this other ____________ that they previously weren’t aware of, so they’re ____________ greatly just in terms of learning about diversity and having a broader perspective on the world around them,” Arvin said.

8 . When you measure the distance between towns on foot, walk to places that you thought could only be reached by car and it will change your mind.

I live in the suburb north of San Francisco, and _________is considered the main transportation for most people here. I still remember how _________I was when I first learned to drive. While driving with music gently _________my heart, I was filled with joy. However, as time went by, that excitement _________. I feared driving, and felt worried and upset. Everyone seems to be in my way especially when I am in a _________. One night, a deer ran out from the dark, knocked against my moving car, and _________across the street. I didn’t dare to get out of my car to see her. Crying on the _________, I hated my car.

When I joined the 21-day mindful walking _________, I began to walk with a mind. During the walking days, I smiled at every stranger _________by me. I walked to the streets that I __________would not pass through and __________a tiny free library on the sidewalk. I began to __________if I had really lived in this town all these years. It’s a completely __________ town that I know so little about!

I felt deeply __________for the walking challenge. Maybe I will set foot on far lands again, yet I know __________is right here and right now.

9 . In high school, Dad got me to play rugby in the first place. I enjoyed throwing the ball around, but I didn't think I had what it _______ to play on a team. "You'll never know what you're capable of _______ you give it a try, Adam. " Dad told me. There was _______ a game where Dad wasn't on the sidelines, cheering me on.

Four years of efforts came down to my last game. I urged my dad to bring our _______

I _______ at my parents before the opening kick-off, and put on my game face. I grabbed at the clothes of an offensive player and _______ him to the field. A loud cheer came from the sidelines. There was Dad with the camera, cheering like crazy. My best _______ ever, a perfect end to my career.

I couldn't wait to _______ the moment again. I pressed Play—the two teams _______ before the game, and then, the sky and clouds! I could only hear my dad ________ "Way to go, Adam!" The truth was that he was crazily waving, too ________ to notice anything.

"I'm sorry,” he said, "I ________ to record you the whole game.   I sensed the ________ in his heart. I firmly answered. "It was your cheers that ________ my courage in that fierce rugby game. " During the ________ recording, I found the unforgettable tune of the game and my entire life.

10 . Trackers on Ice

Just because a scientist puts a GPS tracking collar on a wild polar bear does not mean the animal will willingly keep it on.   _______, these huge collars are purposefully loose so that if one becomes annoying, a bear can _______it. But scientists have now found a way to use signals from the discarded(丢弃的)devices.

“These dropped collars_______would have been considered garbage data,” says Natasha Klappstein, a polar bear researcher at the University of Alberta. She and her colleagues instead used_______from such collars, left on sea ice in Canada's Hudson Bay, to track the ice itself. For their study, published in June in The Cryosphere, the researchers _______twenty collars that sent movement data consistent(与······一致的)with ice drift rather than polar bear _______between 2005 and 2015. The resulting records of how melting ice typically drifts in Hudson Bay are unique; there are no easily _______on-the-ground sensors, and satellite observations often cannot _______capture the motion of small ice sheets.

The team compared the discarded collars' movements with widely used ice-drift modeling data from the U.S. National Snow and Ice Data Center (NSIDC). Collar data indicated that the NSIDC model underestimates the speed at which ice moves around in Hudson Bay--as well as the overall _______of drift. Over the course of several months the model could drift away from an ice sheet's location by a few hundred kilometers, the researchers say.

This means the bears may be working harder, when moving against the direction of the ice, than scientists had   ________ .“Since we're underestimating the speed of drift, we're likely underestimating the energetic effort of polar bears," says Natasha Klappstein. The research reveals________insight (洞悉) into how highly mobile ice moves. As melting increases in coming years, such ice will likely become more ________farther north, in the central Arctic. Scientists had known NSIDC data could underestimate drift speeds, but “any time we can find a data ________,it is a good thing.”

Plus,such data could improve predictions about how oil spills or other pollutants may spread in seas ________ with drifting ice, says Walt Meier, a senior NSIDC research scientist,who was not involved in the study. The findings may even ________future NSIDC models. “It's a really nice data set,” Meier says."And certainly one we’ll take consideration.
