A handsome man can earn a fifth more than an average-looking colleague but a beautiful woman is not paid a penny more than her average-looking colleague, new research has shown.

    The study by senior economists（经济学家）found that being good-looking meant male workers could earn 22 percent more than average-looking colleagues. Researchers said good looks did not give women a similar advantage.

    Andrew Leigh, a former economics professor at the Australian National University who co-authored the report, said: “Beauty can be a double-edged sword for women.”

    “Some people still believe good looks and intelligence are incompatible(矛盾的) in women, so a good-looking women can't be that productive, but it doesn't affect men's pay.”

    He said that although he believed good-looking women may also earn more, the research did not support his theory.

    The research found that handsome men in all jobs, from manual labour（手工劳动）to highly-paid professional careers, can earn 22 percent more than their colleagues doing the same work.

    Men with below-average looks face a battle in the office, with ugliness reducing a man's earnings by 26 percent compared to an average-looking worker.

    Former male model, Caitlan Mitchell, 28, who has a first class degree in history from Edinburgh University and now works for a cosmetics company, told the Sunday Times:' It gives you confidence, and I suspect people tend to warm to you more quickly.”

    The study, named Unpacking the Beauty Premium, was the largest exercise of its kind and repeated a survey from 1984 to see if the beauty premium（美貌溢价) had changed.

    Leigh said the research showed people in the workplace were “lookist(以貌取人的)”and he hoped the findings would encourage employers to remove their prejudice.

    The principles about applying for jobs have altered greatly lately. In the past, people preferred a hand­written application letter. However, nowadays it is becoming more and more common to apply for a job through the Internet. You can find information on the Internet about how to apply for jobs. Information can be found about how to fulfill your application letter, the clothes that you should wear and how to carry out the interview itself.

    The importance of body language is often mentioned, but doesn't always get the attention it deserves. After all, before a word has even been spoken, your body language will have already given people their first impression of you. Additionally, your body language will also give out a lot more information. Based on your body language it can be seen if you are self-confident. It can also show if you are a busy or a quiet type and it helps give an impression of whether you are speaking truthfully or not. Body language can show how enthusiastic you are and if you are a nice person, someone who will take his work seriously, but also someone who has a sense of humor and can enjoy a joke from time to time. The members of the application committee will ask you questions, but your answers won't only be oral. The committee will not only pay attention to what you say, but also to how you say it! Body language will determine first if it “clicks”， and sometimes all it takes is just a few seconds. Everybody uses body language, but it takes place mostly at a subconscious (下意识的) level. Using body language appropriately, you can definitely increase your chances of getting a job.

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, "You should have goals like climbing the mountain. " without the mountain-climbing that we both enjoyed, we couldn't have enough time to spend together because my father was very busy. I really got a lot from mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.

Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds'singing, but as time passed, I got a pain in both of my legs. I wanted to quit climbing. In fact, I hated it at that mountain, but my father said to me, "You can always see a beautiful sky at the top of the mountain, but you can't see it before you reach the top. Only there at the top can you see all of the nice things, just like in life. "

    At that time, I was too young to understand his words. But later after that, I got new hope and confidence. I found myself standing at the top of the sky, which was as clear as crystal.

    Parallel worlds exist and interact with our world, say physicists.

    Quantum mechanics (量子力学), though firmly tested, is so weird and anti-intuitive that physicist Richard Feynman once remarked, “I think I can safely say nobody understands quantum mechanics.” Attempts to explain some of the bizarre (奇异的) consequences of quantum theory have led to some mind-bending ideas, such as the Copenhagen interpretation and the many-worlds interpretation.

    Now there's a new theory on the block, called the “many interacting worlds” hypothesis (假设) (MIW), and the idea is just as profound as it sounds. The theory suggests not only parallel worlds exist, but that they interact with our world on the quantum level and are thus detectable. Though still speculative (推测的), the theory may help to finally explain some of the bizarre consequences inherent in quantum mechanics.

    The theory is a spinoff of the many-worlds interpretation in quantum mechanics—an assumption that all possible alternative histories and futures are real, each representing an actual, though parallel, world. One problem with the many-worlds interpretation, however, has been that it is fundamentally untestable, since observations can only be made in our world. Happenings in these proposed “parallel” worlds can thus only be imagined.

    MIW, however, says otherwise. It suggests that parallel worlds can interact on the quantum level, and in fact that they do.

    “The idea of parallel universes in quantum mechanics has been around since 1957,” explained Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the physicists to come up with MIW. “In the well-known 'Many-Worlds Interpretation', each universe branches into a bunch of new universes every time a quantum measurement is made. All possibilities are therefore realized — in some universes the dinosaur-killing asteroid (小行星) missed Earth. In others, Australia was colonized by the Portuguese.”

    “But critics question the reality of these other universes, since they do not influence our universe at all,” he added. “On this score, our 'Many Interacting Worlds' approach is completely different, as its name implies.”

    Wiseman and colleagues have proposed that there exists “a universal force of repulsion between 'nearby'(i.e. similar) worlds, which tends to make them more dissimilar.” Quantum effects can be explained by factoring in this force, they propose.

    When asked about whether their theory might imply that humans could someday interact with other worlds, Wiseman said: “It's not part of our theory. But the idea of human interactions with other universes is no longer pure fantasy.”

    What might your life look like if you made different choices? Maybe one day you'll be able to look into one of these alternative worlds and find out.

    A typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours' sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the problems happen because our sleep patterns are not fixed, and they change as we grow.

    So a later school start time could help to solve this problem, by ensuring to get their eight plus hours of sleep and react properly to their body's natural rhythms(规律). There has been a general change over the past 25 years to shorten the school day. This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks.

    Later start times could help teens' grades and health. This is mainly because it makes the management of children easier. Managing hundreds of children "playing" requires effective staffing. And there is always the fear that behavior worsens during breaks. So the theory goes that having them in class and strictly managed must be better.

    But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are forced to study ancient history. And teaching staff also move through from one class to another, with hardly a rest or time to refocus.

    Clearly rethinking the school day could benefit everyone included. Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. For teachers, it could also mean a less stressful day all around and what could be better than that?

German cities are redrawing road markings to create new cycle paths for the duration of the Covid-19 lockdown, as cyclists demand more space to physically distance on their way to work.

Local authorities in the Kreuzberg district of Berlin trialled (试行) temporary widening of two cycle paths on 27 March, arguing it would help cyclists keep the required 1.5-metre distance apart while car traffic was down owing to Germans' coronavirus (冠状病毒) restrictions.

On Friday, the council declared the plan a success because it had improved cycling safety while not blocking traffic.

The council said it had used removable tape and mobile signs to mark out the widened paths, which can be removed when the current restrictions on movement are lifted.

Residents in 133 other German cities have formally submitted applications for similar pop-up bike paths to their local authorities on the back of a campaign by Environmental Action Germany (DUH), an environmental NGO.

The campaign group cites new research linking air pollution to higher coronavirus death rates as an argument for redrawing road signs across the country. "The coronavirus is showing us that clean air is necessary," said DUH's chair, Jurgen Resch. "It is now especially important to temporarily make it more important for people to move safely on their bikes. This will help improve air quality, enable exercise in fresh air while keeping a safe distance and avoid unnecessary accidents."

In Germany, bike repair shops are allowed to work because of the Covid-19 going on. Three federal states, Berlin, Saxony-Anhalt and Mecklenburg-Vorpommern, have allowed bike shops to stay open.
