The minute you start talking about what you're going to do if you lose, you have lost.

    Some people have a great fear of losing. In fact, fear is not the best description of what they have. It is more like a crazy phobia(恐惧症) that they cannot keep away from. Day after day, these people allow their fear of losing to control everything in their lives. They are so afraid of losing that they try to keep away from losing without considering the cost of doing so.

    When things start to get out of control, fear begins to come in. As the fear of losing or getting hurt overwhelms(充溢) them, they quickly look for excuses, rather than fight back or find a way to deal with their fear. They never realize that losing is just as common as eating and breathing.

    If one is given a choice, who wouldn't prefer winning over losing? After all, winning is exciting and winning is what living is all about. Although we might try hard all the time, we're not going to win every time. In fact, most of us are going to lose a lot more often than we win and, believe it or not, it's not all bad.

    In order to make the most of our abilities ，we have to take risks every now and then. When we take risks, we might get knocked down, or even knocked flat, but with each failure and each loss, we have an opportunity to get better and get closer to the life we expect.

    I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.

    Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.

    I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.

    I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.

    I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.

    I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise to strangers who try to catch my attention from now on.

    Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.

    This robot looking like a helicopter（直升机）, is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions（作用）are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake.

    This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. "

This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.

    As well as a detector（探测器）that finds victims（遇难者）and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.

    Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.

    Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year.

A Teenage Inventor

    The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

    Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia's method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia's method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

    Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

    "What affects one country affects everyone," Olivia told CNBC. "We have to work together to find answers to the huge challenges which cause harm to the global health." The Connecticut's teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

    Olivia hopes her success will inspire other girls interested in science and computers. "I would just encourage girls to try it in the beginning, and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science," she told CNBC, "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests."

    With the New Year just months away, you are probably looking forward to watching the wonderful fireworks(烟花) shows. Unfortunately, the over ten million blind Americans, and scores more around the world, have never been able to experience this joyful celebration. That may change soon thanks to Feeling Fireworks, a tactile(可触摸的) fireworks experience invented by the masterminds at the Disney Research Lab in Switzerland.

    To experience the show, users stand in front of a large screen, which is made of special material. They then place their hands at the base of the screen and move them around to feel the fireworks. Alternatively, their hands can be placed in the center of the screen, where the initial explosions happen, and then moved across to explore other fireworks.

    As the fireworks begin to explode, one of five nozzles(喷嘴) at the back of the screen starts to send out water, creating shaking movements. One specializes in the “blooming(开花) flower effect,” while another reproduces the“crackle(噼啪声)” effect. The rest take care of rockets and explosions. A computer controls the timing, while a Microsoft Kinect camera tracks the person's movement. According to the inventors, Feeling Fireworks allows users to experience “tactile fireworks that are similar to physical fireworks happening in the sky.”

    First appearing at the User Interface Software and Technology conference held in Quebec City, Canada from October 22 to October 25, 2017, the low-cost technology is still in its early stage, with only a 66 percent success rate. However, the team plans to continue-improving the experience and believes the day when everyone will be able to enjoy the thrill of fireworks shows is not far. When ready, Feeling Fireworks will initially be available only at Disney theme parks, and then hopefully, at fireworks shows worldwide.

    Knowing what to do at checkout and properly preparing for it can turn a potentially heated situation into a quick thank you add goodbye. Below we made a list of five things you should remember at hotel checkout.

Don't be late to check

    Hotels may add an extremely high price for being just a half hour late. If you know you won't make the cutoff time, it never hurts to call ahead and try to negotiate away a potential charge.

    Don't forget to double cheek the room and safe

    Make sure you don't leave things behind. If you have an early flight or checkout time, pack up as much as you can the night before so that last-minute rush isn't too annoying. Also, be sure to take out anything in the room safe.

    Don't forget to tip the housekeepers

    It's always polite to leave some money for the people keeping your room clean.

    Don't ignore the detailed bill

    You may be in a rush, but give the detailed hill a careful look to see if the hotel charge is different from the rate you initially booked.

    Don't get angry

    Shooting at the assistant manager standing behind the front desk probably won't help.

    When dealing with an unexpected item on the bill. Think about how difficult it can be to deal with annoyed customers. Keep calm and things may be solved better and sooner.
