Housework is a frequent source of disputes (争论) between lazy husbands and their hard-working wives, but women have been warned not to expect men to pull their weight any time soon.

    A study from Oxford University has found that men are unlikely to be doing an equal share of housework before 2050. Mothers, the researchers warned, will continue to shoulder the burden of childcare and housework for the next four decades, largely because housework such as cleaning and cooking is still regarded as“women's work”.

    The gap between the amount of time men and women spend on housework has narrowed slowly over the past 40 years. But it will take another four decades before true housework equality is achieved, the study concluded. The research found that in the Nordic countries, the burden of housework is shared more equally between men and women. In the UK, women spend an average of four hours and forty minutes each day on housework, compared with two hours and twenty-eight minutes for men. This is an improvement from the 1960s, when British women typically spent six hours a day on housework, while men spent just 90 minutes every day.

    But progress towards housework equality appears to be slowing in some countries. Dr Oriel Sullivan, a research reader from Oxford's Department of Sociology, said, “we've looked at what is affecting the equality in the home, and we have found that certain tasks seem to be given according to whether they are viewed as ‘men's work' or ‘women's work'.”Dr Sullivan said cultural attitudes taught at school may be responsible for the views of housework. “At school it is much easier for a girl to be a tomboy, but it is much more difficult for a boy to enjoy baking and dancing,” she said.

    Plenty of people dream of traveling to other planets. But “Star Wars” fans can actually visit locations where many of the films' most famous scenes were shot. Here are some of the places where “Star Wars” comes to life.

Hotel Sidi Driss, Matmata, Tunisia

    Perhaps the most famous "Star Wars" landmark in the world, this is where the interiors of Luke Skywalker's childhood home on planet Tatooine were filmed. Centuries ago, Berbers built the underground structure as a real home. Eventually it became a hotel, which George Lucas used to film the first "Star Wars" film. The set decorations came down when the crew left, but were rebuilt in 2000 for "Attack of the Clones." Since then, they've remained, so guests can eat at the table where young master Luke did.

La Grande Dune, outside Nefta, Tunisia

    The igloo(冰屋) outside of Luke's house was filmed about 300 kilometers away on the dried-up salt lake of Chott El Jerid. The igloo is still there, reachable with a decent car at the GPS coordinates 33"50'34. 42"N, 7"46'44.48"E.

    The surrounding hotels are man-made, to create the illusion (幻觉)that the underground house is next to it. The igloo from the 1977 movie was taken apart, but again rebuilt for "Attack of the Clones," and later restored by a fan. Nearby is La Grande Dune, site of the Dune Sea. About 30 minutes from the igloo is the set of Mos Espa, the spaceport town where Anakin was discovered as a young slave.

Redwood National and State parks, California

    Endor, the forest moon home of the furry Ewoks, was filmed among California's giant redwoods. Most of the well-known scenes were shot on private land owned by a lumber company. Since the cast and crew worked on "Return of the Jedi" in 1982, heavy logging has left most of the landscape unrecognizable. But driving through the parks still gives a feel for the set, especially along the Avenue of the Giants highway.

    In Grizzly Creek Redwoods State Park and the Humboldt Redwoods State Park, plates were filmed for some chase scenes.

    At any discussion of a job offer, money can be a deal breaker. Negotiating an attractive deal, however, can be hard for many job candidates because they lack the necessary skills or simply because they're too concerned that pushing for a high salary can cost them the job.

    These factors certainly can be hurdles (障碍), but it doesn't mean that you give up trying to get the best deal you can get. Needless to say, if money isn't a big factor in your decision, you still need to make sure that the deal you're accepting is fair compared to what's offered in the market. Selling yourself short once can impact your future salaries and set you back financially.

    Here are common mistakes that many jobseekers commit in negotiating money.

    Negotiate too early. Timing is of essence in any negotiation, and negotiating a salary too early in the process can cost you dearly. Many employers, in fact, rank this as one of the biggest mistakes job candidates make. The best timing to begin a salary discussion is after you and your future employer are nearly sure that you've been selected for the position.

    Abandon professionalism. It's common that people, after going through a long recruitment process, can be shocked that the salary offered is significantly below their expectations. If you find yourself in this situation, don't abandon your professional attitude or throw a fit. This likely will get you nowhere except the door.

    There're two options to this situation: the first is that the employer is inflexible (不灵活的) about the budget, and in this case, you may just leave and make a graceful exit from the hiring process.

    The second option is that there's some negotiation room for the hiring manager with other decision makers in the organization. If this is the case, you may be surprised that a final push with a positive attitude and a well-delivered presentation about your skills and market price can get you closer to your expected salary. Still, if this is not acceptable, you don't have to take it.

    The single, decisive factor that made it possible for mankind to settle in lasting communities（社区，聚居地）was agriculture. After farming was developed in the Middle East in about 6500 BC, people living in family units did not have to be on the move continually searching for food or hunting their animals. Once people could control the production of food and be assured of a reliable supply of it, their lives changed completely.

    Farming was a revolutionary discovery. It not only made settlements possible and later the building of cities but it also made available a reliable food supply. With more food available, more people could be fed. Population therefore increased. The growing number of people available for more kinds of work led to the development of new social formations. With more and more food, a community could support a variety of workers who were not farmers.

Farming in the world over has always relied upon a dependable water supply. For the earliest societies this meant rivers and streams or regular rainfall. The first great civilizations grew up along rivers. Later communities were able to develop by taking advantage of the rainy seasons.

    All of the ancient civilizations probably developed in much the same way, in spite of a few differences. As villages grew, the production of more numerous goods became possible. Cloth could be woven from wool. Houses made of wood, brick, and stone could be put up.

    The science of mathematics was an early outcome of agriculture. People studied the movements of the moon, the sun, and the planets to work out seasons, By doing so they created the first calendars（日历）. With a calendar it was possible to find out the arrival of each growing season. Measurement of land areas was necessary if field was to be divided accurately. Measurement of amounts, for example, of seeds or grains was also a factor in farming and housekeeping. Later measures of value as money exchange became common.

    All of the major ancient civilizations in Mesopotamia, Egypt, the Indus Valley, and China appeared in the 4th millennium（千年）BC. Historians still argue over which one came into being first. It may well have been the Middle East. This place reaches out from the Nile River in Egypt northward along the coast of former Palestine, then eastward into Asia to include Mesopotamia. In this area people settled along the riverbanks and practiced field agriculture. This kind of farming depended on the reproduction of seed, normally from grain crops.

    I took down the violin I made in the past two months, and walked towards the farmland outside. The violin shined in the sunlight, and I admitted, unwillingly, that it looked good. But I knew it was a mockery (笑柄) of my failure to find beauty.

    “What makes a violin beautiful?”

    I first asked this question as a three-year-old child and now again as a teenager. When I listened to a violin for the first time, I was so astonished by its beauty that I imagined a fairy living in the wooden frame. But fairies faded when I grew older. I wanted a reasonable answer to the question.

    I referred to Professor Ruan, my violin teacher, who introduced the violin to me 14 years ago. This 85-year-old man rhapsodized about (热烈赞美)the legend of Antonio Stradivari. “His violins are the most beautiful works human has ever crafted.” “Make a violin with your own hands," Professor Ruan suggested, "When you play it, you'll know.”

    However, when Professor Ruan introduced to me a violin workshop, what I saw was far from my expectation. In front of me was a fat worker, shirtless and sunburned, soon to become my master. What shocked me most was that the “master” knew nearly nothing about music. His rough hands had been tending crops, not instruments, for most of his life.

Two months later, standing outside the workshop, I was disappointed. Yes, I just finished or copied a Stradivarius violin. But I didn't find beauty in it. Then I remembered Professor Ruan's words, "When you play it, you'll know.” So I closed my eyes, and focused on where my fingers and strings touched. Music flowed suddenly so beautifully that for a moment I doubted my own ears. Slowly I opened my eyes, and with surprise found the fairy of my childhood fantasy dancing to my music — the two-year-old daughter of the master.

    Professor Ruan was right. I didn't find beauty until I played music with the violin, because beauty isn't in the instrument itself. It's just here, deep down, in ourselves.

    My name is Kobus Vermeulen. On February 16, 2015, I was one of five South Africans among the 100 people selected by Mars One to begin training to live on the Red Planet. The Dutch not-for-profit's aim is simple: build a human colony (殖民地) on Mars. Since I have begun this journey, the one question that people ask me most is why I want to leave a good planet for wasteland. Here is why.

    I have been interested in Mars since I was a child, and I always thought that if I had the opportunity to leave the planet, I would take it. So the why begins with a child's dream.

    However, as I grew, so did the why. In my eyes, since the 1970s the public has stopped trying to learn more about space. We've put our dream aside. We're satisfied with getting our dose (一份) of the future from sci-fi movies and comic books. And so the first part of my motivation (动机) is to get people thinking about space travel and the colonization (殖民化) of other planets in real terms again instead of just as sci-fi visions of the future.

    If we want that future, the truth is that we have to build it, and anything worth doing comes with risks. Somebody has to take the risks, and I, along with thousands of other people, am willing to take them.

    But it goes deeper than that. If the task of Mars One is even partially (部分地) successful, it will encourage a new generation of scientists and engineers that will build us an even better future.

    Without a dream, there is no reason to build those things. The public that does not try to understand science and technology does not choose good leaders. Leaders who don't care for science and technology do not make budgets (预算) for it. Besides, without the money, the dream dies. Projects like Mars One are like a focusing lens (聚焦透镜) for dreams. It is an opportunity to change hearts and minds at the grassroots level.
