    Throughout history, artist, inventors, writers and scientists have solved problems in their dreams. Now, let's have a look together at some of them.

    ⒈Paul McCartney Found Yesterday in a dream

    Paul McCartney is one of the most famous singers/songwriters of all time. According to the Guinness Book of Records, his Beatles song Yesterday(1965) has the most cover（翻唱） versions of any song ever written and, according to record label BMI，was performed over seven million times in the 20^th century.

    The tune for Yesterday came to Paul McCartney in a dream.

“I woke up with a lovely tune in my head. I thought, 'That's great, I wonder what that is?' There was an upright piano next to me, to the right of my bed by the window. I got out of bed, sat at the piano, found G, found F sharp minor—- and that leads you through then to B to E minor, and finally back to E. It all leads forward logically. I liked the melody a lot, but because I'd dreamed it, I couldn't believe I'd written it. I thought, 'No, I've never written anything like this before.' But I had the tune, which was the most magic thing! ”

    ⒉Mary Shelley's Frankentein Inspired by a Dream

    In the summer of 1816, nineteen-year-old Mary Wollstonecraft Godwin and her lover, the poet Percy Shelley (whom she married later that year), visited the poet Lord Byron at his villa beside Lake Geneva in Switzerland. Stormy weather frequently forced them indoors, where they and Byron's other guests sometimes read from a volume of ghost stories. One evening, Byron challenged his guests to each write one themselves.

    Mary's story, inspired by a dream, became Frankentein（科学怪人）.

“When I placed my head upon my pillow, I did not sleep, nor could I be said to think—-My eyes shut ,I saw——with my acute mental vision—-the pale student of unholy arts kneeling beside the thing he had put together. I saw the ugly figure of a man stretch out, and then, on the working of some powerful engine, show signs of life, and tremble with an uneasy motion, extremely frightful. The next morning I announced that I had thought of a story. I began that day with the words, 'It was on a dull night of November', making only a transcript(文字稿) of the cruel terror of my waking dream.”

    Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creative enough, to take up singing. But today, things stand differently.

    According to a survey by Tesco Mobile, a UK company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger(博客), or “vlogger(视频博主)”. The survey, carried out among 1,002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal careers.

    This change is undoubtedly as a result of the Internet and social media. They have made it so much easier to reach audience of the world, without having to enter a career in show business in the traditional way.

    In the past, the biggest stars were trained by the Hollywood studios; now, anyone with a computer camera can become a star. Vloggers are the big stars of today because they are normal people interacting(互动) with their fans about everyday life.”

    However, what people see is only the bright side of being a vlogger and they fail to notice the fact that only those who are successful earn fame and fortune. For every success there are hundreds of others who never get off the starting line. There are the dreams that come true and the dreams that remain dreams forever.

    Although being vloggers is popular, some young people choose to follow careers that don't necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It's an online platform(平台) for runners to keep a record of their races. His job allows him to express his enthusiasm, and is always a learning experience. And that's enough for him.

    We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn't finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

    According to Time, of course not, taste has little to do with quality of water.

    According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

    "But it's most likely safe to drink," Norwegian expert Truls Krogh told Science Nordic. "If the water is covered and of good quality to start with, in principle it can last a thousand years. That's because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health."

    People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

    However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

    With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you're more likely to be ill.

    And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to "several health damage, including heart disease and cancer", Time reported.

    Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

I recently read Pablo Picasso's quote, "I'm always doing that which I cannot do, in order that I may learn how to do it." It reminded me of myself—and how I do, learn, and improve. I recalled one of my earliest memories of doing before learning: baking scones(烤饼) when I was 10 years old. I wanted to bake scones for my mom.

I always sat at the kitchen table when my mom baked, and I had observed her process numerous times. She always used a recipe book and followed the process carefully. As I started to try, I didn't know I shouldn't handle the dough (面团) with my hands too much once I had added the baking powder(发酵粉). However, I knew exactly how to roll out the dough and use a cookie cutter to cut the scones, because I had repeated it in my mind hundreds of times.

As my mom arrived home, the smell of freshly baked scones welcomed her into the kitchen. They were baked to golden brown perfection—flat, as a result of over-handling the dough, but they tasted OK. My mom praised me for my attempt, rather than blaming me for the state of the kitchen, which was a surprise! That night she told my dad how proud she was, and what a good job I'd done. Over time, she taught me the finer tricks of baking and cooking.

My habit of doing before learning still stands me in good stead. Whatever computer program or application I have to learn, I do so by simply starting to use it. I learn as I go on, and I've often been able to help others because I've gone through the process of learning from beginning to end. What I discovered from my experience is the wisdom to know when it's OK to do and then learn, and when it's probably better to learn and then do!
