It was a weeknight. We were a half dozen guys in our late teens, hanging around “the flat” — as usual. The flat was poorly furnished, which, after some time, grew tiresome. We wanted action.

    We got in a car, big enough for all of us to crowd into — and off we went, in search of adventure. We soon found ourselves at Blue Gum Corner, a place named after the huge old blue gum tree that stood by there, a well-known local landmark. It stands at a minor crossroad leading to our town. The trunk is tall and smooth with no handholds for climbing. About six metres from the ground the first branch sticks out over the road. We parked beneath the huge old tree and discussed what we might do. All of a sudden we hit upon an idea — a hanging! I was chosen as “hangee”.

    The plan was quite simple. As I stood upon the roof of the car, the rope (绳子) was threaded down my jacket through my collar and down one leg of my jeans. I put my foot through the loop at the bottom. There I hung, still. The boys rolled about laughing until, a car, I hear a car! Before they ran to hide in the nearby field, they gave me a good push so that “the body” would swing as the car drove by.

    To our disappointment, the car simply turned off for town without even slowing. The boys came out of their hiding places and we discussed the situation. Surely they had seen me, hadn't they? Then we heard another car. The act was repeated, but still without any obvious reaction. We played the game about five or six times, but as no one seemed to notice, we abandoned the trick.

    What we did not know was that every car that had passed had unquestionably seen “the body” and each one, too scared to stop, had driven directly to the local Police Station. Now at that time of the night, the local policeman was sound asleep in his bed, so the first person sent to the scene was the traffic officer that happened to be on duty that particular night. He had been informed that some person had been killed, by hanging, at Blue Gum Corner. When he arrived, the body was gone! And he was hearing “unnatural sounds” from the surrounding area. As far as he knew, some fierce animal was hiding in the field before him, possibly dragging a body behind him — and we thought we were scared!

    He went to his radio and made a call that really began to worry us. I lay so close that I could hear every word. He called for the “armed police” and a “dog team, better make it two” and he had a “serious situation” at Blue Gum Corner. Then the police officer arrived. After a briefing from the traffic officer he decided not to go into the field until armed police and dog teams arrived. Now two spotlights were on the field and none of us could move.

    As luck would have it, police cars cannot leave their spotlights on all night without charging their batteries. So, after a time, the two officers began lightening the field by turns, allowing us the opportunity to move on our fours for freedom. One by one, we all managed to steal away and make our way home. Behind us we left what must have looked like a small city of lights, police cars, roadblocks, barking dogs, armed officers and an old rope hanging from a tree.

    When I think back to that night, to that tree, to what the drivers of the cars think happened, to what police believe happened, and to what I know happened, I am reminded of a simple truth — our eyes see darkness and light, color and movement, our ears hear only vibrations (振动) in the air. It is how we explain these vivid pictures that shapes our “reality”.

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an "environmental chamber." The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    "We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km."

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    Recently, many e-commerce platforms, including Didi Taxi, Ctrip, Fliggy, JD ad Taobao, have been uncovered that they are cheating their frequent customers. Their ways are pretty clever. When there are new users or conservative old users, they will give a quite appealing price to attract them into registering and buying goods. However, their big data is not that friendly to the stable users and frequent visitors. The system always offers them higher price for the same products or service. How does this happen? According to the data analysis, the system knows clearly that although they feel the price is high, they will finally pay the bill. By collecting and analyzing users' profiles, buying habits and other information, big data recommends the same products to different users with different prices.

Companies also try other ways to make money, making online consumption far more worrying. For example, video websites always offer 120 seconds' advertisements, which drives people crazy. And even if you pay for the membership to get rid of the ads, you have to “enjoy” 15-second “private” ads. By broadcasting them, companies make huge profits — second to the membership fees. Also, owning 100Mbps network, you still put up with the slow speed when you are downloading a song. You have no choice but to become a VIP when you seek high quality services. Users seem to be lambs(羊羔) among wolves. Even though they say,” Since you have money, I'll charge you more”, we can't do anything about it.

    It pains us that we haven't figured out a way to deal with the problem. The only thing we can do is replacing our iPhones with Android phones if we want to buy a membership card, and applying for new accounts if we want cheaper hotels. Not finding a way to fight back, we can't do anything but accept them passively.

    Qing-Feng Steamed Dumpling Shop. Daniang Dumpling. McDonald's. What do these companies have in common?

    Well, besides all being fast food chains, their logos are all red. And it's not a coincidence. Color is one of the many that companies use to connect with customers. And if fast food wasn't hard enough, those red logos might make it even harder to ignore.

    The average human can see ten million colors, but red is special. It's one of the first colors our ancient ancestors thought important enough to name. Early human languages were uncolorful. There were words for “black” and “white” and “red” but not much else.

    As a result, we have a deeper connection to red than any other color and we react to it in certain ways that actually play to fast food companies' advantage. For starters, researchers have found that red can cause a sense of urgency. On top of that, it also has an ability to whet (刺激) our appetites. And when you pair those two together, you've got the perfect recipe to attract hungry customers who want food, fast.

    So the red logo isn't just a welcoming sign. It's a seduction (诱惑) for your brain. Now, it's unclear why red makes us feel this way. But perhaps it has something to do with where the word comes from. Many ancient languages first named red from their word for “blood”. But red's bloody beginning has transformed. During medieval times, for example, red was worn by royals as a status symbol. And today, brides in many parts of India are married in red dress.

    In fact, red is one of the few colors today that cultures all over the world view positively. And it's no wonder companies attach so much importance to their logos. After all, we're a visual species. Despite having five senses, 80% of the information our brains process on a daily basis comes from our eyes. And according to marketing company WebPageFX, nearly 85% of consumers say the main reason they choose one product over the other is color.

    Just think what McDonald's would look like in blue, green, or pink! It's just not the same, right?

    From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.

    The international space station （ISS） is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.

    As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seem to be the only country that has the ability to build a space station alone, and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone's effort and will benefit everyone.

    Led by the U. S. and Russia, the ISS is a joint project between six space agencies involving 16countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten﹣year's hard work in construction. China has applied for participation in （taking part in） the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ﹣F/T1 carrier rocket blasted off （leave the ground） and successfully carried the Tiangong﹣1into space on September 29, 2011, China takes a big step toward its Space Station Era.

    Some West media suggested that the successful launch of Tiangong﹣1 would disturb the balance of global space power, raising concerns about "China threat". China's space project is not designed for military purpose but for developing space technology to explore space resources and make use of them for mankind's well﹣being.

    Working with a stressed mind is like swimming with a jacket on, while a mind free from work stress is light like the wind and it can help you accomplish your daily tasks easily. To relieve (缓解)stress and lighten your mind, you must first understand the nature of stress and the reasons why it builds up. Then you can easily beat stress.

    Talk it out

    Talking to others helps relieve work stress especially when you and the person you talk to are in the same boat and under the same work stress. Your worries will be divided! If you are your own boss, you need some good advisers around you, who know your trouble and talk sense. If there is no such persons at your workplace, let there be one at home, who is a friend, a family member or a guide that you can talk to.

    Let music calm your mind

    Music has the power to take you into a new world, away from your worries. Taking a break to listen to some favorite music is also a great way to relieve stress.

    Take a walk

    If there is a park around, go and have a walk there. You can eat some snacks sitting on the grass. Move around, look at the world around you and forget your work for a while. Let your body get some exercise. A walk works as it also clears your thoughts. You can listen to music while going on a walk.

    Have a life beyond the workplace

    If you keep thinking about nothing other than work all the time, there is bound to be stress. So, throw away your thoughts about work after you leave your office and get a life beyond it. Have a life beyond the workplace, and you can relax after work.
