    Do you and your friends ever talk about your dreams with each other? If you do, you might have noticed something interesting – some of your friends seldom remember their dreams, but some can always describe their dreams so clearly that it seems like they're describing things that really happened to them. What makes those people different?

    The answer is simple. There are two different types of dreamers – low dream recallers（回忆者）and high dream recallers.

    Low dream recallers usually remember their dreams only twice a month. But high dream recallers are able to remember them about five mornings a week. And a new study suggests that activity in a certain part of the brain could have something to do with it, reported The Huffington Post.

    Perrine Ruby, a French researcher at the Lyon Neuroscience Research Center, studied 41 people (21 high dream recallers and 20 low dream recallers) and recorded their brain activity.

    She found that a part of the brain called the temporo-parietal junction (颞顶联合区) was more active in high dream recallers than in low dream recallers – both when they were sleeping and awake.

    This brain area collects and processes（编程）information from the outside world. This means that high dream recallers know more about what's happening around them. For example, when they are awake, they respond (对……有反应) more strongly to hearing their own names, and when they are sleeping, they are woken more easily by sounds and movements.

    By closely studying people's brain activities, Ruby found that high dream recallers have twice as much “wakefulness time” during sleep as low dream recallers do. And it is during these short times of wakefulness that the brain remembers dreams.

    “The sleeping brain is not able to remember new information,” Ruby told The Washington Post. “It needs to wake up to be able to do that.”

    This is not hard to understand. Just try to think of your own sleeping experiences. If you are worried during the night, you are more likely to remember your dreams, but if you sleep well, you will remember little in the morning, and this is because “you never get a chance to remember”, Robert Stickgold, a Harvard Medical School researcher, told The Washington Post.

    I'm the engine that keeps you working, and I'm here to share some of my secrets.

    I have 100 billion nerve cells (神经细胞), so you need to consider before you blame (责怪) me for not being so fast enough. It's not really my fault: information travels through me too fast and sometimes I can't keep all of it.

    The Internet is making me weak. A study found that you've been relying more on the Internet. That means I'm going to forget more over time. Scientists have been worried that our ability to think is being lost.

    In general, I'm about ten percent larger in men than women. It doesn't make men smarter. It just lets me control their different bodies. Actually, it's more common for women to get angry, but men can't focus on a thing well. They usually have language difficulties.

    Your mobile phone scares me. A new study showed that more than one hour of mobile phone use can get me in trouble. Mobile phone radiation (辐射) might cause me to be in a worse situation.

    Some parts of me never sleep. It's important for you to get a good night's sleep. Sleep helps to improve memories. In fact, when you are asleep, some parts of me are still working hard on my duty.

    Besides, laughter is really the best medicine for me. So remember to laugh more for my better situation.

    Sometimes it seems that time is flying. Perhaps it doesn't need to feel this way. Our experience of time can be possibly changed. By understanding the psychological (心理学的) processes behind our different experiences of time, we might be able to slow down time a little.

    One basic law of psychological time is that time seems to slow down when we're exposed (接触) to new environments and experiences. The law is caused by the relationship between our experience of time and the amount of information our minds process. The more information our minds take in, the slower time seems to pass.

    It follows, then, that we have different experiences of time in different situations. In some situations, our life is full of new experiences. Our minds process a lot of information and time seems to slow down. In other situations, we have fewer new experiences and the world around us becomes more and more familiar (熟悉的). We become insensitive to our experience, which means we process less information, and time seems to speed up.

    How can we slow down time? Here are two suggestions.

    Firstly, since we know that familiarity makes time pass faster, we can expose ourselves to as many new experiences as possible. We can give ourselves new challenges, meet new people, and expose our minds to new information, hobbies and skills. This will increase the amount of information our minds process and expand (增加) our experience of time.

    Secondly, and perhaps most effectively, we can give our whole attention to an experience-to what we are seeing, feeling, tasting, smelling or hearing. This means living through our senses rather than through our thoughts. For example, on the way home, focus your attention outside of yourself, instead of thinking about the problems you have to deal with. Look at the sky, or at the buildings you pass, traveling among them. This open attitude to your experiences helps take in more information and also has a time-expanding effect.

    To a certain degree, we can understand and control our experience of time passing. It's possible for us to slow down time by expanding our experience of time.

    When you are waiting for a bus at a station, a 31-metre-long bus is coming to you. You must be surprised. In fact, the 31-metre-long bus is the longest bus in the world. And the bus comes from Germany. An ordinary bus is only about 10 metres long and it can carry only 80 people once. But the longest bus can carry 256 people. So we will need fewer buses in the future. The longest bus can save energy, too. That's to say, it will take less energy than an ordinary bus. Moreover, the driver can drive the longest bus as easily as an ordinary one.

    However, firstly, it has to spend $ 10, 000, 000 buying the longest bus. Someone jokes that we can buy a lot of ordinary buses with that money. Secondly, people think that it is hard for the longest bus to travel on the bustling streets. It may cause new traffic problems. Thirdly, it is easy for someone to get onto the bus without buying a ticket.

In the western world, Chinese takeout with rice and fortune cookies(幸运饼干) is a popular kind of food. But this kind of Chinese food isn't very authentic(正宗的), it is very {#blank#}1{#/blank#}[̍dIfrənt] from real Chinese food. Now over the years, real Chinese{#blank#}2{#/blank#}(dish) have become more popular in foreign countries as well.

Chinese people who live {#blank#}3{#/blank#}[ə̍ brɔːd] introduced many of them. Some have been popular in foreign countries for many years, {#blank#}4{#/blank#}others are new, like tanghulu. It is a traditional Chinese snack that's made{#blank#}5{#/blank#}fruit, usually Chinese hawthorns(山楂). The fruit is stuck on a stick of bamboo. Then it is {#blank#}6{#/blank#}(cover) with sugar syrup(糖浆), which becomes hard after it cools down.

Wang Jialiang, a tanghulu vendor(摊贩) from China, sold 8, 000 sticks in Russia {#blank#}7{#/blank#}one day. Tanghulu made him{#blank#}8{#/blank#} [̍ feIməs] in Russia, with his picture{#blank#}9{#/blank#}(appear) in the local newspaper. In the Russian city of Vladivostok, the deputy mayor(副市长) is a big fan of the snack, always coming to buy it {#blank#}10{#/blank#}(he)from Wang Jialiang.

Researchers have developed a printer that produces 3D personalized chocolate. The printer, which produces 3D chocolate by b{#blank#}1{#/blank#} up successive layer is thought to be an improvement in gift shopping. It has already received huge amounts of interest from shopkeepers. 

It is hoped that project will eventually see people designing and creating their own products across a wide range of gifts. The l{#blank#}2{#/blank#} researcher, Dr. Liang said, "What makes this technology special is that users will be able to design and make t{#blank#}3{#/blank#} own products. "In the long term it could be developed to help consumers. design many products from different m{#blank#}4{#/blank#}" From the shape of a child's favourite toy to a friends' face, the possibilities are endless and only limited by our ideas, " he said. 

The research team is now looking to develop a consumer stage where people will be able to send their own chocolate designs for 3D printing. They will also be able to browse through the designs of other users, but can't c{#blank#}5{#/blank#} them without permission. Dr. Liang added, "Eventually we can may see many mass-produced products being r{#blank#}6{#/blank#} by unique designs created by customers. "

This is an imaginative application of two developing technologies as well as a good example of how creative research can be applied to create new products and sales-ideas. 

He also said, "By combining developments in engineering with the commercial potential of the digital economy, we can have a look at the future of new markets—creating new jobs and, in this case, sweet business opportunities.
