BEIJING — The launch of a new manned space mission brings China closer to the establishment of a permanent space station, international experts say.

    Chinese taikonauts, Jing Haipeng, 50, and Chen Dong, 37, were blasted off into space onboard Shenzhou-11 at 7:30 am Monday and will spend 30 days in the Chinese space laboratory Tiangong-2.The launch marks a key step toward China's plan to eventually operate a permanent space station. The successful launch of the Shenzhou-11 spacecraft is another step forward to put China among leading players in space technology, said Alexander Zheleznyakov, a Russian expert on history of space flights. China's experimental space lab will help provide solutions for spacecraft of different functions to approach and anchor, and for a long-term operation of life support system, said Zheleznyakov. Shenzhou-11 is scheduled to anchor on Wednesday with Tiangong-2, which is part of China's plan to build a permanent space station by 2022.

    China can now test technologies for cargo spacecraft anchoring, life support system operation and water recycling to ensure a long-term continuous operation of its space station in the future with less dependence on renewal from the Earth, he said. If all goes well, China will launch the unpiloted Tianzhou-1 cargo ship next spring to autonomously tie up with Tiangong-2. Tianzhou-1 will be capable of automatically transferring rocket fuels, a vital requirement for space station grouping and maintenance, according to a report by Columbia Broadcasting System (CBS).

    "That will further their anchoring abilities needed for the larger space station," Johnson Freese was quoted." Tiangong-2 is supposed to be able to stay in orbit for two years or longer, so that's taking them (Chinese) really close to 2019 or so. I think this will be their last big technology test phase before going to their large space station," said Freese.

    IPhone owners are vainer（虚荣）and spend more on clothes and grooming（仪容）than those who have BlackBerrys and Android phones, new research claims.BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets are most creative and the best cooks.

    The study, carried out by TalkTalk Mobile, surveyed 2,000 owners of the three major smartphone brands to determine whether the choice of handset was an extension(延伸) of their personality. The study rated users in various walks of life using a point scoring system including personalities, daily habits and the type of industries they work in.

    Other results from the study found that people with an iPhone are more image conscious and generally consider themselves more attractive than those with other handsets. They are most likely to describe themselves as adventurous, bright and are most likely to work in media, publishing and education. They also believe their boss rates them highly. Apple owners also tend to have done more travelling and are the most active on social media sites.

    BlackBerry owners were found to be the least punctual(准时的), but despite putting in the least hours at work they are the most active phone user—sending more texts and making more calls in the average day than any other phone user. They are more social and have more friends overall. They also earn nearly two and a half thousand pounds a year more than other smartphone owners, with an average salary of $27,406. BlackBerry users classed themselves so loud and mainly work in the health, finance or property sectors. They were also found to drink more tea and coffee each day than any other phone user.

    Android owners were found to watch more TV than others and drink the most alcohol—consuming more in an average week than iPhone and BlackBerry drinkers. They have the most jobs in engineering, the government and public services and environmental services. They have the best manners and are more shy and relaxed than their counterparts.

    Dan Meader, Director of Mobile at TalkTalk, said,“Many of us have our mobile phones on us almost constantly so they do become an extension of us in many ways. It's interesting to see then how the choice in handset may reflect different aspects of personality and the results do show some unusual difference

    Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress.This difference may explain why men are more likely to suffer from stress related disorders.

    Until now，psychological research has maintained that both men and women have the same “fightorflight” reaction to stress.In other words，individuals either react with aggressive behavior，such as verbal or physical conflict (“fight”)，or they react by withdrawing from the stressful situation (“flight”)．However，the UCLA research team found that men and women have quite different biological and behavioral responses to stress.While men often react to stress in the fightorflight response，women often have another kind of reaction which could be called “tend and befriend.” That is，they often react to stressful conditions by protecting and nurturing their young (“tend”)，and by looking for social contact and support from others—especially other females (“befriend”)．

    Scientists have long known that in the fightorflight reaction to stress，an important role is played by certain hormones(激素) released by the body.The UCLA research team suggests that the female tendorbefriend response is also based on a hormone.This hormone，called oxytocin，has been studied in the context of childbirth，but now it is being studied for its role in the response of both men and women to stress.The principal investigator，Dr.Shelley E．Taylor，explained that “animals and people with high levels of oxytocin are calmer，more relaxed，more social，and less anxious.” While men also secrete(分泌) oxytocin，its effects are reduced by male hormones.

    In terms of everyday behavior，the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed.They may phone relatives or friends，or ask directions if they are lost.

    The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work.The typical father wanted to be left alone to enjoy some peace and quiet.For a typical mother，coping with a bad day at work meant focusing her attention on her children and their needs.

    The differences in responding to stress may explain the fact that women have lower frequency of stressrelated disorders such as high blood pressure or aggressive behavior.The tendandbefriend regulatory(调节的) system may protect women against stress，and this may explain why women on average live longer than men.

Mark Twain's First Money

      Mark Twain was asked one day if he could remember the first money he ever earned. He thought a long time and then said, "Yes, it was at school. I can remember everything about it. School boys in those days did not take good care of their chairs and desks. There was a rule in our school that if anyone damaged his desk or chair, he would have to pay five dollars or the teacher would beat him in front of the whole school."

    "One day I damaged my desk in some way, I had to pay five dollars or be beaten before the whole school. My father said it would be too bad to have our family disgraced in front of the whole school. He agreed to give me five dollars to hand over the teacher. But before he gave me the money, he took me upstairs and gave me a beating."

    "But as I had one beating and I decided I would take another beating at school and keep the five dollars. So that's what I did. That was the first money I ever earned."

    "Bill, you never miss!" Joe said admiringly. "Unless I'm in a real game," Bill complained. "Then I miss all the time." Joe knew that Bill was right. Bill performed much better when he was having fun with Joe in the school yard than he did when he was playing for the school team in front of a large crowd. "Maybe you just need to practice more," Joe suggested. "But I practice all the time with you!" Bill objected. He shook his head. "I just can't play well when people are watching me." "You play well when I'm watching," Joe pointed out. "That's because I've known you since we were five years old," Bill said with a smile. "I'm just not comfortable playing when other people are around." Joe nodded and understood, but he also had an idea.

    The next day Joe and Bill met in the school yard again to practice. After a few minutes, Joe excused himself. "Practice without me," Joe said to his friend. "I'll be back in a minute. "

    Joe hurried through the school building, gathering together whomever he could find-two students, a math teacher, two secretaries, and a janitor(看门人). When Joe explained why he needed them, everyone was happy to help. Joe reminded the group to stay quiet as they all went toward the school's basketball court. As Joe had hoped, Bill was still practicing basketball. He made five baskets in a row without noticing the silent people standing behind him.

    "Hey, Bill!" Joe called out finally. Bill turned. A look of surprise came over his face. "I just wanted to show you that you could play well with people watching you," Joe said. "Now you'll have nothing to worry about for the next game!"
