Thinking about the future isn't special skill. Actually, everyone does it all the time. We schedule future activities and appointments on our calendars. We make to-do lists, a promise to ourselves of how we will spend our future time and energy. We look up the weekend's weather. We make predictions about the results of sporting events. We practice, study and train for upcoming events that matter to us. We daydream about events we're eagerly looking forward to. We worry about others.

    Most of this common future thinking is about the near future: the next few minutes, hours, days, weeks, months or maybe even the next few years of our lives. Little time is spent thinking about what our lives will be like or what actions we should prepare to take in the far future: ten years, twenty years, or even fifty years from now. This kind of far-future thinking is the domain of professional futurists.

    Futurists are trained to imagine distant realities that seem impossible to others: technologies that don't exist yet, great changes to laws, strange diseases most likely to infect us in the year 2031. Why indeed think about such distant futures? Are there psychological and social benefits to imagining the world, and our lives, decades in advance? And if so, what does it take to become good at imagining the far future?

    These were the fascinating questions that we recently explored with other futurists. I was personally inspired by the discussions, and learned a lot about how futurists imagine the future of life. They specifically wanted to use their imaginations to make the world a better place. Another big benefit for me was that this way of thinking is a skill that can be taught. Society would benefit greatly if we all learned the valuable skills that enable us to think about what things would be like in the future.

    When I spent the summer with my grandmother, she always set me down to the general store with a list. Behind the counter was a lady like no one I'd ever seen.

    “Excuse me,” I said. She looked up and said, “I'm Miss Bee.”

    “I need to get these.” I said, holding up my list. “So? Go get them. ” Miss Bee pointed to a sign. “There's no one here except you and me and I'm not your servant, so get yourself a basket from that pile.”

    I visited Miss Bee twice a week that summer. Sometimes she shortchanged me. Other times she overcharged. Going to the store was like going into battle. All summer long she found ways to trick me. No sooner had I learned how to pronounce “bicarbonate of soda” and memorized its location on the shelves than she made me hunt for it all over again. But by summer's end the shopping trip that had once taken me an hour was done in 15 minutes. The morning I was to return home, I stopped in to get some run.

    “All right, little girl,” she said. “What did you learn this summer?” “That you're a meanie!” I replied. Miss Bee just laughed and said, “I know what you think of me. Well, I don't care! My job is to teach every child I meet life lessons. When you get older you'll be glad!” Glad I met Miss Bee? Ha! The idea was absurd.

    Until one day my daughter came to me with homework troubles. “It's too hard,” she said. “Could you finish my math problems for me?”

    “If I do it for you, how will you ever learn to do it yourself?” I said. Suddenly, I was back at that general store where I had learned the hard way to add up my bill by myself. Had I ever been overcharged since?

    On Sunday 23 April, most than 30,000 people participated in the 2017 London Marathon, running 26.2 miles (42.2 kilometres)around the city center.

    The London Marathon has taken place every year since 1981. At the first one, just 6, 225 people completed the course, and since then it has grown into one of the biggest sporting events in the world. It is one of the 'World Marathon Majors', which is a competition made up of six global marathon events. The overall male and female winners receive $1 million in prize money between them. There are eleven people who have run every London Marathon since it began—they call themselves the 'Ever Presents.

    This year, the winners of the London Marathon were surprisingly both from Kenya—Daniel Wanjiru, who finished in 2 hours and 5 minutes, and Mary Keitany, whose time was 2 hours and 17 minutes.

    However, most marathon runners are not professional athletes. They are amateurs who have trained for months to raise money for charity or just as a personal challenge. For example, Tom Harrison took three days just to reach the run's halfway point, as he is crawling the course on his hands and knees dressed as a gorilla(大猩猩), trying to raise money and attention for the charity 'The Gorilla Organisation'.

    Matthew Rees was another runner to encourage people, as he stopped just before the finish line to help David Wyeth run the last 200m.They did not know each other before, but Matthew saw that David was exhausted and possibly close to collapsing, and wanted to help him finish.

    Every year there are lots of touching stories like this from the London Marathon, and it is a huge achievement even to run the 26.2 miles!

    Rosa Parks became famous in 1955 when she refused to give up her seat on a bus to a white passenger in Montgomery, Alabama. She was important in the movement for civil rights（民权） in the American South during the 1950s and 60s. At the time, blacks in the South were forced to sit in the back of public buses and to give up their seats to white people.

    Parks moved to Detroit, Michigan, in 1957 to escape death threats. She continued living in Detroit until her death in 2005, at age 92. But the house in Detroit where Parks lived for many years was abandoned and scheduled to be torn down. Her niece, Rhea McCauley, bought it for $500 to stop it from being destroyed. She then gave it to American artist, Ryan Mendoza.

    Mendoza and others took it apart and then sent it across the Atlantic Ocean to the German capital of Berlin. There, he led efforts to rebuild the house. It now is behind his own house in Berlin. It gets daily visitors, although it is difficult to find, Mendoza said.

    But less than a year after the house was rebuilt in Berlin, Mendoza decided it should be returned to the United States. He made the decision after deadly violence took place at a recent white nationalist event in Charlottesville, Virginia. That incident increased calls for removing statues of Confederate（美国南部联邦的） leaders from the Civil War in the U.S.

    Mendoza said there are not enough civil rights monuments "to balance things out" with the Confederate statues. He said the Rosa Parks house belongs back in America "Imagine if the house were on a public setting in a prominent city in the U.S.," Mendoza said. "That's an education tool that shouldn't be denied by the American people. They have to know their past."

    The house would be welcomed back in Detroit. Detroit has failed to protect historical homes in the past. Such houses include the former home of Ralph Bunche, the first African-American to win the Nobel Peace Prize. Detroit's failure to protect history also is shown by the loss of the Rosa Parks house, Hammer said.

    You may find yourself wondering: do blind people dream? Dream sleep is generated deep within the brain. As it is a function of the brain, and not the eyes, blind people dream as much as a sighted person would. It is interesting that the timing of the blindness in life may in fact influence the content of the dreams, however.

    Research has evaluated the sensory experiences of blind people while dreaming for decades. These findings have been interpreted (解释) within the context of sighted people's experience of dreams. It is useful to consider the content of all dreams to better understand where it differs among the blind.

    Most dreams contain features that are both visual and kinesthetic (related to movement, such as falling). More than half of dreams contain a sound. It is rare for people to describe other sensory experiences, such as those related to smell, taste, and pain. It is estimated that these latter three elements occur in less than 1 percent of dream reports. Interestingly, women more often experience smell and taste in their dreams while men more often report sound and pain.

    Blind people are more likely to report feelings of touch, taste, and smell in their dreams compared to sighted people. This likely corresponds to their waking experience which relies more on these senses. They do not have dramatic differences in dream content, except that they seem to have less aggression in their dreams.

    Despite these subtle differences in dream content, can blind people see when they dream? Some blind people actually can see in dreams, but it depends on when they lost their vision. Individuals who are born blind or those who become blind at a young age (typically by the age of 4 or 5 years) do not have visual imagery in their dreams. On the other hand, those who become blind after 5 or 6 years of age are able to see in their dreams. Therefore, there seems to be a window in the development of the brain in which the capacity to have visual dreams is established.

    Claude Monet, Pablo Picasso and Leonardo da Vinci ... the art world has never lacked talent. And now, a new painter is ready to join the list although this one isn't even human.

    Next month, auction house Christie's Prints and Multiples will make history by offering the first piece of art created by artificial intelligence (AI) for sale. The painting is a portrait of a man called Edmond De Bela- my, and is expected to be sold for up to $10,000.

    The work, which features a man with a mysterious look on his face, was created by software developed by the French art group Obvious. Laugero-Lasserre, an art collector, called the work "grotesque and amazing at the same time". This isn't the first example of Al-produced artwork, as AI has already been used to write poems and compose .songs. However, many people doubt whether it should be called art at all.

According to Russian writer Leo Tolstroy (1828 -1910), art is about creating emotion (情感). It's "a means of …joining people together in the same feelings' he once said.

So, if the emotion behind art is what makes it, the ability to create and use tools is what makes human Icings different from other species. And as a tool itself, the AI technology used to create the portrait is the result of a lot of effort made by several designers. Together, they "fed" the AI a huge collection of paintings from the 14th to the 18th centuries, until it was able to work out how to make similar paintings of its own.

    The introduction of AI art could be the beginning of a new artistic movement. However, not everyone is ready to welcome these high-tech artists just yet.

    "The human mind is what's behind the AI technology. And the human mind is not a cold, hard fact," said Oscar Schwartz, a professor of AI. "Rather, it in something that's created with our opinions and something that changes over
