3 . I remember that it was a fall morning when the orchestra (管弦乐队) teachers came into Miss Newell’s third-grade classroom. “You have hands for the viola(中提琴),” Miss Ciano told me. I was excited because my hands were finally good for something. I told my parents I wanted to play, and naturally, they agreed.

Since I first touched the viola, I haven’t been able to put it down. Ignoring the difficulty, I am pulled closer to it each day.

Classical music is truly my best friend. It is the trusted friend of every man, woman and child. Various feelings are expressed in classical music. I discovered that when I was eleven and played a cello concerto (大提琴协奏曲) of Bach in a competition, the first movement was joyful, but the second movement was mysterious and full of pain. From the piece, I learned that music expresses not only feelings, but also sudden mood changes. By listening to classical music, I know that someone else shares these feelings. Since I am lucky enough to be able to play classical music, I am comforted by it when I am upset. It gives me a way to escape from my problems for a short period. Classical music can express my joy, sadness and anger.

Now look back at that fall day in the third grade and think how gullible I was for believing that anyone, even music teachers, could tell whether hands were perfect for a certain instrument. I’m certain they told me I had “ viola hands” not because they were fortune-tellers(算命师), but because there was a lack of violists in our district. Classical music is one of the best things that ever happened to mankind. If you get introduced to it in the right way, it will become your friend for life.

4 . As I lie here in my hot, uncomfortable hospital bed, all I can think about is how badly I want to leave this place. It has been four days of doctors giving bad news, medicine injections, procedures, MRIs and restless nights. I have been able to eat one meal a day due to the surgeries I was scheduled for later. I ask my mom to bring me my car keys and on my key chain, there is a soft piece of leather made from my first baseball glove. She looks worried and sad, handing the keychain to me. In the fibers of the leather are so many memories that have transformed me as a person.

I grab my keys and touch a smooth piece of leather. It is a nice coffee brown and about 3 inches in length. Every time I touch it, I think of one thing - baseball. The key chain is made from my first baseball glove that I cherished so much It carries great moments like championships as well as moments when I strike out and lose. Each one has transformed me not only as a baseball player, but as a person.

All of a sudden, my nurse walks in and I jump when I hear her voice. She didn't mean to interrupt , but I need more medicine. Once she leaves, I focus back and grasp the cowhide. I rub my fingers up and down just feeling this reminder of the game. It takes me on a wild road trip through my brain and I am stopping at each baseball memory. This time I begin to picture the people that are involved in my baseball life.

I open my eyes, realizing the road trip that I used to be on has gone with the wind. My gaze shifts to the clock on the opposite wall. Almost an hour has passed! Even in tough times the things and people you love can help you escape and you will get over all the difficulties.

5 . Do you remember what happened on Sponge Bob Square Pants yesterday? The day before? If so, you may be in need of a TV timeout!

Kids today are watching more TV than they watched before, researchers say. Kids ages 6 to 11 in the United States watch more than three hours of TV each day. Ten years ago, children watched only about two hours and 40 minutes of TV each day.

Why the increase? Experts say more TV shows today are focused, or aimed, at kids.

Some people want to limit kids' TV time. Researchers say that children who watch TV shows for more than three hours a day do not do as well in school. However, some programs can help kids learn. One example is BrainSurge. Some people say the show teaches kids facts.

How do you know whether a TV show can make you smart? Think about what you learn from watching, says Aletha Huston. She is a TV expert. But, she warns, don't spend too much time watching. “Limit the amount you watch. Get off the couch and do something else.”

6 . Have you ever noticed that the stars sometimes appear brighter in December, January and February? There's a link between cold air and the night lights. "Part of it is that it tends to be drier in the winter," said Diane Tumshek, an astronomer at Carnegie Mellon University in Pittsburgh, Pennsylvania. Even though it's invisible, moisture can change the way light moves through the air. And in the summer, moisture can make stars appear more dull.

Air temperature is also what puts the twinkle twinkle in the little stars. "Even on very clear nights, some of the atmosphere is cooler, and some of the atmosphere is warmer,” said Tumshek, who also works with the Allegheny Observatory. And when the light from a star passes through those bubbles of varying temperatures, "it bends and shifts the light, so that we are seeing stars appear to dance or twinkle,” she said.

For star lovers in the United States, there's another factor that comes into play for bright winter stars, although this is a matter of coincidence. During Earth's journey around the sun, “there are just simply more bright stars visible from the Northern Hemisphere in the winter sky," Tumshek said. If you really want to see a shiny star, just try to find a burning ball of gas called Sirius near the horizon. At 8.6 light-years away, Sirius is relatively close to Earth and the brightest star visible in the night sky. It is also large — nearly twice as big as our sun and 20 times as bright. So this winter, when the world turns cold and it seems like we should be spending more time indoors, consider asking an adult to go exploring outside. With a warm coat and a clear sky, any night can be turned into a treasure hunt. All you have to do is look up.

7 . Since apps like Uber and Lyft came on the scene, ridesharing services have dramatically changed the way people get around. A new study out of Columbia University reveals a downside of these services. It turns out that ridesharing trips cause an increase in the number of accidents involving motorists and pedestrians at pick-up and drop-off locations.

Previous studies on the relationship between ridesharing services and vehicle crashes compare cities where ridesharing services are available with cities where they are not, and this makes results somewhat ambiguous. In this study researchers analyze individual trips to make the picture a little clearer.

Researchers analyzed data from 372 million ridesharing trips in New York City between 2017 and 2018. Whenever a crash occurred in the city, they calculated the number of ridesharing trips that began or ended in the area at the time of the accident. They compared this with the number of trips that took place in the same location one week before and one week after the crash. Researchers did the same calculations for regular taxi rides as part of their analyses. Also, separate analyses were performed based on the type of people injured in the crash: pedestrians, motorists or cyclists.

The results of the analyses show that the rise in ridesharing trips is associated with an increase in the number of accidents involving pedestrians and motorists, but not cyclists. Furthermore, they did not find this same association between taxi trips and accidents.

“Ridesharing is changing the way we move around cities.” says first author Christopher Morrison. “It is becoming clear that the technology reduces alcohol-related crashes, but these benefits do not seem to extend to the overall number of crashes. These findings help explain why that might be---- because the reductions in alcohol-related crashes are offset (抵消) by increases in other types of crashes.”

Researchers hope that cities and ridesharing services will use the results of this study to take measures that might reduce the number of crashes. “In crowded areas with large numbers of rideshare pick-ups and drop-offs, cities could consider building taxi-rank style infrastructure (基础设施) to protect pedestrians and prevent crashes, ”concludes Morrison.

8 . I was eleven years old standing outside in just my underwear while I watched the house that I grew up in rapidly burn to the ground.

A few minutes earlier I had been in bed when a scream woke me up. My grandma’s bedroom was just next to mine and my elder brother’s. A fire had broken out there and awakened her. Hearing her scream, my elder brother jumped to action, running from room to room quickly to wake everyone in the house. However, before we could do anything, the fire had consumed (烧毁) the old and wooden house.

I stood there shivering (颤抖) while the fire destroyed my books, clothes, and toys. I watched helplessly while my Mom cried and my Dad sighed. I wondered what was going to happen to us now that we had lost all of our things. As I looked around, though, I realized something for the first time: What matters aren’t things. I saw my elder brother running across the swinging (摇摆的) bridge by our house to get help. I saw my eldest brother who was on crutches (拐棍) from an earlier accident standing unsteadily on one leg. I saw my grandma and dad wrapped in each other’s arms and my mum holding our little dog. I realized at that moment that we were all alive. Everything that was essential had survived the fire. Our lives would continue. We would survive without the “stuff” that was burning. We would all be around to love each other for many years to come. And that was all that mattered.

I still think of that fire at night. It helped me to become who I am today. It showed me for the very first time what is truly essential in life. It helped me to learn that the love we share is far more important than the things we possess.

Live your life then for the things that matter, not for the things you own. Love others. Let the fire inside of you make this world a warmer place. Let your soul shine bright.

9 . Jack was born without eyes. He was very lucky as he grew up having other kittens (young cats) to socialize (交往) with, and was used to people from the moment he was born. However, when it came time to find the kittens homes, no one knew where Jack would end up.

That’s when I got an e-mail from my friend. All she asked was “Do you still want one of the kittens? There’s one here with no eyes and no one would like to take him”. Without thinking I told her that I did want the kitten.

When we first brought him home, Jack stayed mostly in my room. After about a day he had no issues running around and climbing on everything. At times he gets lost in the house, he’ll stop. But we just call his name and talk to him and it isn’t long before he finds his way back to us.

A few weeks after getting Jack, we got a new cat named Bear. Jack and Bear have become best friends. It doesn’t matter that he can’t see. He always knows when Bear is around. He’ll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. They run after each other around and wrestle (摔跤). They’ll lie down in the grass together when tired.

Jack is truly an inspiration. I’ve owned lots of kittens in my life, but Jack is the happiest and most playful. He doesn’t feel sorry for himself. He doesn’t need pity. I think Jean, owner of Gumbo, another eyeless cat, said it best when she told me that cats don’t have disabilities; they have adaptability.

10 . Will human beings find intelligent alien (外星的) life anytime soon? Probably not, according to theoretical physicist Stephen Hawking.

Hawking made the prediction during the Breakthrough Starshot announcement in New York City on April 12. At the news conference, Hawking, along with Russian billionaire sponsor Yuri Milner and a group of scientists, detailed a new project that aims to send a large number of tiny, wafer-size (薄饼大小的) spaceships into space to the neighboring star system Alpha Centauri (半人马座阿尔法星).

If these tiny spaceships travel at 20 percent of the speed of light, they'll be able to reach Alpha Centauri in just 20 years, Milner said. Once there, the spacecraft will be able to do a 1-hour flyby of Alpha Centauri and collect data that's impossible to gather from Earth, such as taking close-up photos of the star system, studying space dust molecules (分子) and measuring magnetic fields (磁场), said Avi Loeb, chairman of the Breakthrough Starshot Advisory Committee and a professor of science at Harvard University.

In addition to learning about space technology, the audience wanted to hear about aliens--specifically, when scientists might find them.

Hawking took questions from reporters in advance so that he would have time to prepare his answers.

Hawking has famously predicted that intelligent aliens might threaten humankind. Indeed, when asked about what Earthlings should do if we came across intelligent alien life, he said, “We should hope that they don' t find us.”

Other researchers at the conference offered a more optimistic view of alien life.
