Chinese tech giant Tencent Holdings Ltd, the largest global gaming provider and the operator of QQ, an instant messaging software service, has launched a series of scientific exploration events aimed at encouraging young people to explore the outside world, instead of being continuously absorbed online.

    “QQ has been in the market for 18 years, but it is not aging, and its application has become younger and trendier. We hope that more young Chinese can use the app to connect with different people and views worldwide. We never worry about losing game players. Instead, we hope that players can actually go out to learn more,” said Li Dan, general manager of marketing department of the social network group at Tencent.

    China's gaming market netted (净赚) sales revenues of 218.96 billion yuan ( $33.75 billion) in 2017, jumping 23.1 percent year-on-year. Meanwhile, the number of mobile gain players in China reached 462 million, adding 10 percent over the last year. According to Tencent the number of active users of QQ, who are 21 years old or younger, has been increasing, and they tend to use the app for a longer time.

    Starting May 22 of last year, QQ organized free trips for young people to Galapagos, Namibia, Spain and the Antarctic, but it didn't reveal the specific amount it contributed to those trips. During each trip, it selected three to four participants from those who uploaded videos and made specific travel plans online. The finalists stand out with their clear video statements and their enthusiasm about going on adventures.

    “Tencent's approach appears to be contradictory with its own interests. But, in fact, this is consistent with the company's long-term growth strategy and will promote its business by establishing a good social image,” said Neil Wang, president of consulting firm Frost & Sullivan in China.

    Do you jump out of bed early, wide awake and ready to start your day？ If so, you would be called an "early bird". Perhaps, you hate the sound of your alarm clock（闹钟） each morning and have little energy until afternoon. If so, you're probably a "night owl".

    Most people can be divided into such two groups, but what makes us this way？ And is one better than the other？ There are different opinions.

    Usually, early risers have been praised as hard-working while those who prefer to get up late are considered lazy. Most people believe the early bird catches the worm.

    Yet some scientists now believe "night owls" can really focus(集中) longer and produce more than early risers.

    Research has found that the early bird does not always get the worm. In a Belgian study, both "morning people" and "evening people" were watched during their normal asleep and awake routines(常规).After 10 hours of being awake, the "evening people" became more alert(思维敏捷的). However, the "morning people" became sleepy and less focused. Researchers believe the reason for this difference is that night owls receive a last-minute increase from their brains. This added energy allows them to stay alert for longer periods of time.

    Environment, lifestyle, activities and childhood routines all may have an effect on sleeping habits, yet genetics(遗传学)may play the biggest role.

    It is possible to change your sleeping habits through regular bedtimes, early exercise and by avoiding midnight snacks. But if you're happy rising early or staying up late, you're probably doing what works best for your own personal body clock.

    A recent university study found that current electric cars could be used for 87% of daily car journeys in the US. That figure could rise to 98% by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” —drivers' concerns about running out of petrol on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. In fact, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars met with doubt, and their high price drove customers away. Thanks to improvements in battery capacity(电池容量), recharging times, performance and price, the current generation of electric cars is starting to persuade critics.

    As well as progress on the road, electric vehicles are taking to the sea and sky. Electric boats are among the oldest electric vehicles, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric planes are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make electric flight a reality.

    Electric vehicles do not produce any emissions(排放物). Were the US to act on the study's findings and replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

    A recent experiment proves that bees can save time and energy when they fly around to different flowers.

    Dr Nigel Raine, from the Royal Holloway University of London, has always been interested in finding out why animal behave like they do. He is also interested in bees. It was not a surprise when he and some other scientists from Queen Mary University of London discovered that bees can quickly solve a problem that takes computers many days.

    Flowers make pollen (花粉), and when bees visit them, they carry the pollen to other flowers. The plants need the pollen to make seeds that will grow. Dr Raine notes that we get a lot of our food from plants, so it is important to know how the bees move around and take the pollen between flowers. The scientists wanted to examine the journey that the bees take and how they save energy when they do this. They completed the experiment on the roof of Queen Mary University, using artificial flowers and a large amount of nectar, a sweet liquid produced by flowers. They taught one bee to visit all the flowers in one place at the same time. When the bee got to know the location of the flowers well, they saw how it flew around and returned home with the nectar. After this, they changed the locations of the flowers. The scientists thought the bee would follow the route it knew already. This would mean that it followed a longer route than it needed to, and so it would use more energy. They watched the bee carefully as it travelled between the flowers in their new location, and they made notes. But in the experiment, the bee changed its route and flew a shorter distance.

    The problem that the bee solved is similar to a maths puzzle called the 'travelling salesman problem'. A salesman who goes to different places to sell things wants to travel the shortest distance. But he has to calculate the length of many possible routes to know which one is the shortest. A computer can calculate this but the experiment shows bees can do the same calculation quickly with a tiny brain. Scientists are very interested in how they do this. It would help us to understand how pollen is moved around. In addition, if they find this out, it could help us to improve communication networks. This might help humans to reduce traffic jams when there is an accident, for example.

    This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. As I searched the name, I found that there were two famous people having the same name who looked completely different! One invented hundreds of uses for peanuts(花生), while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; let the coin decide. I flipped(掷) a coin and Ah! Tails (背面)! My report would be about the great man who invented peanut butter, George Washington Carver.

    Weeks later, I stood in front of the classroom and proudly read my homework. But things started to get strange. I looked around the room, only to find my classmates with big smiles on their faces and tears in their eyes and my stone-faced teacher. I was completely lost. "What could be causing everyone to act this way?"

    Oh well, I dropped the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, "My report is on George Washington, the man who started the American War of Independence." The whole world became quiet! How could I know that my teacher meant that George Washington?

    Of course, my subject result was awful. Sad but fearless, I decided to turn this around. I talked to the headmaster Miss Lancelot, but she said firmly: No re-dos; no new score. I felt that it was not fair, and I believed I deserved a second chance. So I threw myself heartily into my work for the rest of the school year. Ten months later, I sat in the headmaster's office again, but this time a completely different conversation. I smiled and flashed back to the terrible moment at the beginning of the year as the headmaster told me I was good enough to skip(跳过) the 6th grade and started the 7th grade next term.
