1 . What is talent? Are you born with it? Or does it seem to develop over time? Before I start, I’d like to say that one thing everyone agrees on is that the most skilled musicians have worked hard to get there.
While it’s true that a few of us had enough “talent” to avoid extra practice to do just as well as those who did, those who worked hard easily beat us. It is, in fact, very likely that if some of us “talented ones” had actually been practicing and improving our skill, we would have achieved a whole different level.
Another aspect of talent seems to be heart and passion (酷爱). The people I see who are the most talented musicians are crazy about music. They eat, breathe, and live music and they make an extraordinary effort to make it part of their lives. As Remus Badea said, desire for the musician-to-be is significant for them to be successful. This desire is easily found in those considered to be talented. When you want and love something so bad, it drives you and your entire character can be shaped around it. Such determined passion seems to produce incredible skill and talent.
The third aspect (方面) of talent is having talent around you. When surrounded by talented musicians, it only seems natural that you start to catch up to their level Take a look at almost any group of musicians in history. The more talented people in the group the more talented the group is as a whole. A great example of this is the relationship between audio producer and artist. The artist turns up to the studio with their song, and as they work through recording it, the audio producer will often suggest various changes to the song to make it better.

2 . Happiness is not a warm phone, according to a new study exploring the link between young life satisfaction and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University (SDSU).
To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social interactions and their overall happiness.
On average found that teens who spent more time in front of screen devices — playing computer games, using social media, texting and video chatting — were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions.
"The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising — two activities reliably linked to greater happiness."
Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of screen devices over time happened at the same time as a general drop-off in reported happiness in U. S. teens. Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep.

3 . On paper, hydrogen（H2）looks like a dream fuel. Coal, oil, and natural gas produce carbon dioxide, which warms the earth when burned, Hydrogen produces pure water. Hydrogen packs more energy into less space than a battery（but certainly less than petrol）. Also, empty tanks（燃料箱）can be refilled with hydrogen much faster than refilling empty batteries with electricity.
While in practice, things are trickier. Storing a meaningful amount of hydrogen gas requires pressing it several hundred-fold. Changing it into the liquid form is another option, but it should be cooled to-253C. Both processes require a heavy and strong tank. While a 700 bar tank is acceptable for a city bus or a truck, adapting it for use in small vehicles is very difficult because the pressure during refilling would be too great.
The solution? Powerpaste.
A German team of researchers, led by Marcus Vogt, have come up with an interesting "powerpaste", which can store hydrogen energy at atmospheric pressure, ready for release when needed. It is so named because it comes in tubes and looks like toothpaste（牙膏）, not in its traditional form of gas.
The main ingredient（原料）of the paste is magnesium hydride, a substance that reacts with water to form hydrogen. The escaped hydrogen can then be directed into a fuel cell, where it reacts with oxygen from the air to produce electric power.
Refueling is very simple, as instead of going to a filling station, drivers and riders can simply replace an empty tube with a new one and refill the water tank.
Given that powerpaste only begins to break down at temperatures of around 250℃ it remains safe even when a vehicle stands in the baking sun for hours.
However, we will have to be patient. Just because researchers have succeeded in developing a new fueling way does not mean that we can expect to see such vehicles on the road anytime soon. It will indeed be several years before this concept is turned into reality.

4 . There are two species of crocodile in Australia—the saltwater crocodiles and the freshwater ones.
Saltwater crocodiles are among the world's largest crocodiles, with males often reaching five metres. But some can reach six to eight metres. Females grow up to 2.5 metres long.
Saltwater crocodiles live in rivers, and coastal waters in northern Australia and eat a wide variety of prey. The young ones stick to insects, small reptiles and fish. But adults hunt for bigger prey like snakes, monkeys and cattle. And they have been known to attack humans.
Freshwater crocodiles, however, aren't usually dangerous to people. They live in freshwater streams, rivers and large water holes in northern Australia. Freshwater crocodiles aren't as big as saltwater ones either, reaching a length of three metres at most.
Crocodiles first appeared 200 million years ago and lived originally on land. But they soon evolved into aquatic (水生的) animals.
These reptiles are excellent predators (肉食动物) and have few natural enemies. Crocodiles have about 30 or 40 teeth in each jaw. And it is the jaw that gives a unique feature to them.
A crocodile can close its jaws with such force that it can break the bones of some animals. Yet, once the jaws are shut, they're so weak that they can be held together by a person's hand.
To reproduce, crocodiles, like other reptiles, lay eggs. One female can produce between 20 and 90 eggs at a time. Once laid, female crocodiles bury their eggs in sand or mud, where they are left to hatch. Some females stay in the area to protect the nest and look after the young after they hatch, but often other predators eat the eggs.

5 . We have studied in Songpu High school for several months. When I first went into the school gate and saw my new classroom and teachers, I thought I would have a new start. The school life is very busy and exciting. There are many activities in our school, such as Sports Meeting, Science Week, Art Week and so on. We all take an active part in them. I have made many new friends and we often help and learn from each other in study.Our teachers have taught us a lot. They not only teach us how to study but also teach us how to be a useful person in society. They tell us which thing is worth doing.Habit is a second nature.Our teachers often remind us to form a good habit.
People often said: There is no royal to learning. Now I feel it is true. The study now is far more different than before. I often find there is something difficult to understand at once. At this time, you must spend a lot of time studying by yourself or you won't make progress. Of course study is hard but when you make progress you'll find it is interesting.
Our school is clean and beautiful. There are many trees and flowers around it.In order to make our school more and more beautiful we should try our best to keep it clean.
Today we are proud of Songpu. Tomorrow Songpu will be proud of us.

6 . The secret to happiness is keeping busy, research has found.
Keeping the mind occupied with tasks — no matter how meaningless — keeps off negative emotions, the study found.
However, the bad news is that humans are seemingly born to be lazy in order to save energy, according to Professor Christoper Hsee, a behavioral scientist at Chicago University.
In a study, 98 students were asked to complete two surveys. After they had completed the first, they were made to wait 15 minutes to receive the next one. They were given a choice of either handing in the first survey nearby or at a more distant location they had to walk to. Whichever option they chose, they received a chocolate bar. It turned out that approximately two-thirds (68 students) chose the lazy option. Those who had taken the walk reported feeling happier than those who had stayed put.
Prof. Hsee concluded that keeping busy helped keep people happy. He said the findings, reported in the journal Psychological Science, had policy implications.
“Governments may increase the happiness of idle citizens by having them build bridges that are actually useless,” he proposed.
At the individual level, he advised, “Get up and do something. Anything. Even if there really is no point to what you are doing, you will feel better for it.” He added, “Incidentally, thinking deeply or engaging in self-reflection counts as keeping busy, too.”
“You do not need to be running around. You just need to be engaged, either physically or mentally.”
1. Keeping busy can make people happy because________.| A．it can help people get rid of laziness | B．it can make people sleep better |

7 . A Portland, Oregon man has become the first person to travel across Antarctica by himself without receiving any assistance.
Colin O’Brady has completed the 1,500-kilometer trip. He crossed the continent in 54 days. Friends, family and other people followed his progress through messages and pictures he left on social media.
O’Brady spoke with his wife Jenna Besaw by telephone soon after he completed the journey. “It was an emotional call,” she said. “He seemed overwhelmed by love and appreciation, and he really wanted to say ‘thank you’ to all of us.”
The 33-year-old O’Brady documented the trip on the social networking services Instagram. He called his journey “The Impossible First”. He wrote that he traveled the last 129 kilometers in one big, final push to the finish line. The distance took over one day to complete. O’Brady wrote, “While the last 32 hours were some of the most challenging hours of my life, they have quite honestly been some of the best moments I have ever experienced.”
The day before, he wrote that he was “in the zone” and thought he could make it to the end without stopping. “I was listening to my body and taking care of the details to keep myself safe,” he wrote. “I called home and talked to my mom, sister and wife. I promised them I would stop when I need to.”
Other people have traveled across Antarctica, but they all had some form of assistance. They either had better, more plentiful supplies or devices that helped move them forward.
In 2016, British explorer Henry Worsley died in his attempt to travel alone across Antarctica unassisted. Worsley’s friend Louis Rudd, also from Britain, is attempting an unaided solo journey in Worsley’s honor. He was competing against O’Brady to be the first to do it. Besaw told the Associated Press that her husband plans to stay in Antarctica until Rudd finishes his trip.
1. What did O’Brady think of his journey in Antarctica?| A．It was pleasant. | B．It was discouraging. |
| C．It was impossible to complete. | D．It was hard to complete. |

| C．Keeping in touch with them. | D．Stopping the travel halfway. |
| A．To wait for another explorer. | B．To compete with others. |
| C．To help other explorers. | D．To make his victory recognized. |
| A．The Antarctic Continent | B．The Impossible First |
| C．Traveling in Antarctica | D．An Incomplete Journey |
8 . A 15-year-old scientist and inventor has been named as Time's first ever Kid of the Year.
Rao is a high school student from Colorado. She was chosen from 5,000 U.S.-based nominees ( 提 名 ). Time said in a statement that Rao stood out for her ability to apply scientific ideas to real-world problems and her efforts to motivate other kids to take up their own causes. Rao told the Associated Press that the prize is “nothing that I could have ever imagined. And I'm so grateful and just so excited that we're really taking a look at the upcoming generation and our generation, since the future is in our hands.” She insists that starting out small doesn't matter, as long as you're enthusiastic about it.
It's just the latest recognition for the teenager, who was named last year to the Forbes 30 Under 30 list. Rao won praise in 2017 after she developed a portable device（设备） to detect lead (铅) in water. She went on to cooperate with scientists in the water industry to try to get the device on the market.
The young scientist has also developed an app called Kindly that uses artificial intelligence to help prevent cyberbullying (网络欺凌). It allows teens to type in a word or phrase to find out if the words they're using are hurtful and amount to（等于）bullying, and thus should be avoided.
In an interview with Time, Rao said that her pursuits（追求） in science started early as a way to improve conditions in society. In a world where science is increasingly questioned or challenged, Rao insists that its pursuit is an important act of kindness. It is the best way that a younger generation can better the world. Science and technology are being employed as never before to handle various issues, such as global warming, the outbreak of disease and so on, she noted.
“We have science in everything we're involved in, and I think that's the biggest thing to put out there, that science is cool, invention is cool, and anybody can be an inventor," Rao said.“ Anybody can do science.
1. What is one of the reasons for Rao being honored by Time?| A．The up-to-date ideas she had come up with. |
| B．The large amounts of time she had devoted. |

| C．Her exposure to challenges. | D．Her concern about society. |
| A．High School Student Struggling for Big Dream |
| B．Young Scientist Named TIME's Kid of the Year |
| C．Scientific Achievements Applied to Our Real Life |
| D．Advanced Inventions Used in Bettering the World |
9 . In October, 2019, Beijing Daily warned the youth that they shouldn't let Internet slang （俚语） deepen the generation gap（代沟），after People Daily started a discussion on Chinese microblog Weibo on how to "explain" the youth's Internet slang terms to parents. The post got 40,000 likes. People were commenting that they couldn't keep up with the rapidly developing Internet lingo （术语）in China.
People also fear that Chinese Internet slang will negatively influence broader linguistic （语言的） trends of Mandarin Chinese, in particular, the gradual taking over of pinyin, the romanization of traditional Chinese characters using the Western alphabet. As pinyin gets widely used when people text or write on mobile phones or computers, while less and less people write characters by hand, people gradually forget how to write them, which is called "character amnesia" in China.
2019’s latest slang terms add a further simplification: the use of pinyin acronyms. "Awsl" in pinyin, for instance, means Ah, wo si le (Oh, I'm gonna die), and is used if something is too cute or adorable. "Nsdd" stands for ni shuo de dui (you're right).
Certainly, as an age-old written language, Chinese has been evolving and developing over the years. But the Chinese Internet lingo is unlikely to replace the existing use of Mandarin Chinese, but will rather be enriching it by adding another layer.
Acronyms aren't new. They have appeared with the limited space available in early-generation cell phone messaging. Some of them have become a part of the English language, such as BTW (by the way) and LOL (laugh out loud), while others had a rather short lifetime. That's likely to be what's going to happen with China's Internet slang terms. Some are going to be old in a few weeks, while others might make it into mainstream use, and as they do, young net users are coming up with new slang words to differentiate themselves.
In China, using Internet slang means belonging to a certain generation that likes to watch the same talk shows, play the same games, etc., and therefore, creates unity. Older generations don't have to feel left out, and certainly don't have to fear a degradation (没落)of the Chinese language. While language development is unavoidable, Internet slang is not going to let 6,000 years of Chinese written language completely change overnight.
1. The public are worried about Chinese Internet slang abuse because| A．It's used by children to keep secrets from parents. |
| B．It can cause confusion even among young people. |
| C．It was invented in response to the limited messaging space. |
| D．It will rarely have a positive effect on linguistic trends of Chinese. |
| A．They add variety to the language. |
| B．They are replacing its traditional vocabulary. |
| C．They make the language more global. |
| D．They only have temporary effects on Chinese. |
| A．a sense of purpose |
| B．a sense of group identity |
| C．a sense of cultural pride |
| D．a sense of safety |
| A．Is Media Helping Older Generation Understand Internet Slang? |
| B．Is Chinese Language Too Powerful to Be Largely Affected? |
| C．Is Mandarin Chinese Useful to Bridge the Generation Gap? |
| D．Is Internet Slang Deepening the Generation Gap, Ruining Chinese? |
