    As a well-known Chinese TV hostess, Dong Qing is now hosting two cultural shows, Chinese Poetry Conference and Readers. The two shows are encouraging people to love traditional culture and find the beauty of life.

    Dong was born in a highly educated family in 1973. she had a great love for traditional literature(文学)from an early age. In 2015 when she was about to study in the U.S, Dong received an invitation from the director of Chinese Poetry Conference asking her to be the hostess. Because of her passion for traditional literature, Dong accepted the job.

    "The contest interests me very much. Hosting it is a process of learning about poetry and performing, "said Dong. To her great joy, the show has become more and more popular.

    Under the slogan(口号)"Reading touches people's hearts", the new TV show Readers has become a success. It invites famous guests from all walks of life to read something. Dong works as both hostess and producer.

    Readers became a turning point in Dong's 21 years of hosting. She said it brought her "quite a huge challenge".

    "There is no shortcut(捷径) in this world. If you want to be a good host, you need to make thorough preparations, said the beautiful hostess. "The charm of life lies in its unknown, so we just have to try and keep going.

①When it comes to Chinese students considering studying in foreign countries, many of them usually believe that life will be easy and enjoyable. Unluckily, it's possible that students with those thoughts will be disappointed very soon after landing at the airport.

②So, what are the problems you may have, and how can you deal with them?

③Teaching and learning styles in America are very different from those in China, requiring more critical thinking (批判性思维) and teamwork. In a normal American classroom, one project might be done by a study group in which every person has their own responsibility.

④So don't worry about your language or any grammar mistakes. Just watch what other students do, and don't be afraid of asking any questions. The discussions, or sometimes even arguments, that your group members and you hold are possible to be the beginning of a friendship.

⑤Besides schoolwork, another important thing faced by overseas students is homesickness or loneliness. You may miss your parents' cooking, your pets, or even your old bed. Being away from home can create bitter feelings, especially when faced with the challenges of getting used to a new environment.

⑥What I strongly suggest is to try hard to deal with these feelings. Be open to new friendships. Sign up for school activities, and give yourself permission to enjoy life at school, even if you miss home a lot. Be organized and keep a diary to check your progress. Write down three new things that you're grateful for every evening, as well as three things you're looking forward to every morning.

⑦Studying abroad is never simple. In fact, there will be many difficulties every day. But I'm sure you will overcome your difficulties and make your time overseas a success.

①Google's company, DeepMind, recently announced that their research team has created a ping-pong robot. This robot can play at the same level as human amateur (业余) players.

②The research team wrote about their work on a website called arXiv. A team member said, "This is the first learning robot that can play ping-pong as well as human amateurs. " The robot has a six-axis robotic arm that can move back and forth and side to side on a rail at the bottom.

③In 29 games against human players, the robot won 13 times, which is a win rate of 45%. The human players were all new to the robot, and their skill levels ranged from beginners to advanced players. The researchers said, "The robot lost all the games against high-level players but won all the games against beginners and 55% of the games against intermediate players."

④To make the robot play at a human level, the team used a layered and modular strategy(分层和模块化的策略).This means the robot can do basic skills like forehand topspin and backhand blocks. It also has a high-level controller that acts like a brain. During a game, it can choose the best moves based on the game situation, the robot's abilities, and the opponent's skills. After the game, the robot can analyze (分析) the data and improve its skills.

⑤The researchers noted that the robot still has some weaknesses. For example, it is not very good at backhand shots and has trouble with fast, high, low, or strongly spinning balls. They plan to improve the robot by making better control algorithms(算法)and better hardware.

David wanted to be an airplane pilot one day. He loved everything about 1 . 

David was so interested in his air projects that he didn't remember the time. Sometimes he even 2 to do his homework. Once, he was late in preparing his part of a group report. As a result, all the three students in his group got low(低的) grades. "I'm sorry, 3 look at this fantastic model plane!" 

One day at school, David spent his lunch time under a tree drawing a picture of his new spaceship design. He heard the bell at the end of the lunch, but could not make 4 leave. Surely Mrs. Carl would understand 5 he was late when she saw his wonderful idea, he thought.

An hour later, David walked back to his classroom. "Where were you, David? I sent many people to look 6 you." Mrs. Carl said.

"I'm sorry, but I just had to finish this spaceship design." said David as he tried to show Mrs. Carl his 7 .

"But we had a special speaker this afternoon, an airplane pilot who talked about his job. He just finished his speech(演讲) and left."

David's smile fell, along with his 8 . "I forgot! How could I miss him? I can't believe I missed the 9 part of school for the whole year." 

After this, David learned a lesson. He 10 not only look at the sky, but also come back to earth.
