In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity; others say that competition is bad because it sets one person against another and because it leads to unfriendly relationship between people.

    I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit of success, the development of many other human qualities is sadly forgotten.

    However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “I may have lost, but it doesn't matter because I really didn't try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one's self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve (缓解) can we discover a new meaning in competition.

    Located in Los Angeles, University of Southern California is in the heart of a leading city. Although LA ranks highly in The Economist s Safe Cities Index, navigating and city calls for certain safety precautions (预防措施) along with practicing common sense.

    Mobile Safety App Powered by LiveSafe

    The Mobile Safety App powered by LiveSafe, manage by the USC Department of Public Safety and the USC Department of Emergency Planning, is a free downloadable app that that mobile users can use to initiate contact with emergency responders around the campus. Features include: immediate “push button” calls to DPS, easy reporting for suspicious activity or crimes in progress, and location services to notify friends of your route through campus.

    Blue Light Phone Locations

    The University Park has multiple blue light phones that are strategically placed throughout campus. Take note of where the closest ones are on your route. They come in handy in case you lose your phone or in an emergency. These phones are directly connected to USC's Department of Public Safety's 24-hour communications center. Besides emergency needs, it can also be used to report suspicious activity, request for an escort (护送) if you feel unsafe and to report a crime.

    Trojans Alert

    Trojans Alert is an emergency notification system that allows university officials to contact you during an emergency by sending messages via text message or email. When an emergency occurs, authorized USC senders will instantly notify you with real-time updates, instructions on where to go, what to do (or what not to do), whom to contact and other important information. All members of the USC community, as well as parents and regular visitors to campus, are strongly encouraged to sign up for Trojans Alert.

    After decades of playing catch-up with the U.S. and Russian space programs, China did something neither nation nor any other had done this December: land a spaceship on the dark side of the moon.

    Strictly speaking, of course, the moon has no dark side. But because of the way it orbits Earth, our natural satellite shows us only one side－the other is hidden from our view. No one even saw the far side until 1959, when the Soviet Luna 3 spaceship flew around for a look and sent back photos. No astronaut or spaceship went there until this December, when the China National Space Agency (CNSA) launched a 2,500-pound lander called Chang'e-4 to the southern end of the lunar far side.

    Chang'e-4 operated a small rover (探测车) to survey the geography there for the first time ever. By examining the geography of its landing area, Chang'e-4 could solve longstanding puzzles about the moon, including how it formed 4.5 billion years ago. Chang'e-4 also carried a very small lunar biosphere (生态圈) containing silkworm eggs and a tiny greenhouse designed to grow potatoes in order to study the growth of the seeds on the moon.

    Besides Chang'e-4, China plans to launch Chang'e-5 in 2019. Its mission will be to gather moon rocks using an orbiter, a lander or collector, an ascent stage (上升器) and a capsule that will separate from the orbiter and return the rocks to the earth. ―With these missions, the Chinese will have shown complete mastery of flight in the space between the earth and the moon, said Paul Spudis, an experienced lunar researcher based in Houston.

    CNSA has already outlined ideas for Chinese astronauts to follow the robots to the moon. Pei Zhaoyu, deputy director of CNSA's Lunar Exploration and Space Program Center, told that China plans a permanent robotic lunar station in about 10 years and suggested a human presence on the moon another decade or so after that. Spudis said China's ambitious Chang'e-4 and Chang'e-5 missions should send human's plans for lunar return into rapid development.

    Our most important institutions, our schools and our workplaces, are designed mostly for extroverts (性格外向者).

In the typical classroom, students are often divided into groups—four or five or more kids all facing each other. And kids are working on countless group assignments. Even in subjects like math and creative writing, which you think would depend on unaccompanied flights of thought, kids are now expected to act as committee members. As for the kids who prefer to go off by themselves or just to work alone, those kids are seen as outliers (局外人) often or, worse, as problem cases. And the vast majority of teachers believe that the ideal student is an extrovert as opposed to an introvert (性格内向者), even though introverts actually get better grades and are more knowledgeable, according to research.

The same thing is true in our workplaces. Now, most of us work in open plan offices, without walls, where we are subject to the constant noise and stare of our coworkers. And when it comes to leadership, introverts are routinely passed over for leadership positions, even though introverts tend to be very careful, much less likely to take outsize risks —which is something we might all favor nowadays. And interesting research by Adam Grant at the Wharton School has found that introverted leaders often deliver better outcomes than extroverts do, because when they are managing thoughtful employees, they're much more likely to let those employees run with their ideas.

    In fact, some of our great leaders in history have been introverts. I'll give you some examples. Eleanor Roosevelt, Rosa Parks, Gandhi -- all these people described themselves as quiet and soft-spoken and even shy. However, they all took the spotlight, even though every bone in their bodies was telling them not to. And this turns out to have a special power, because people could feel that these leaders were in control, not because they enjoyed directing others and not out of the pleasure of being looked at; they were there because they had no choice, because they were driven to do what they thought was right.

    One of my wonderful memories is about a Christmas gift. Unlike other gifts, it came without wrap(包装).

    On September 11^th, 1958. Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying. "I promised you a gift, and here it is." What an honor! I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories. 1 told it over and over how much I loved it!

    One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I heard Mum and Dad whispering such words as "hopeless", "pitiful", and "dying", which sounded ominous.

    Christmas was coming. "Don't expect any presents this year." Dad said, pointing at the socks I hung in the living room. "If your baby brother lives, that'll be Christmas enough." As he spoke, his eyes filled with tears. I'd never seen him cry before.

    The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say. "What? He's all right?" He hung up and shouted upstairs. "The hospital said we can bring Richard home!" "Thank God." I heard Mum cry.

    From the upstairs window, I watched my parents rush out to the car. I had never seen them happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I downstairs. My sacks still hung there flat. But I knew they were not empty; they were filled with love!

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
