The morning had been a disaster. My tooth was aching, and I'd been in an argument with a friend. Her words still hurt: “The trouble with you is that you won't put yourself in my place. Can't you see things from my point of view?” I shook my head stubbornly—and felt the ache in my tooth. I'd thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.

    “If you come by right now,” the receptionist said, “the dentist will fit you in.”

    I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short time? Why wasn't he as busy as the others?

    In the dentist's office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.

    When I told her my fears, she laughed and said, “Don't worry. The dentist is very good.”

    “How long do I have to wait for him?” I asked impatiently.

    “Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.

    “The artwork?” I was puzzled.

    The chair went back, suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.

    What a relief！

    Have you ever lost your direction? Then you might find satellite navigation(satnav) systems(卫星定位系统) helpful.

    A satnav system uses groups of satellites. They send information to a receiver(接收器), such as your smartphone. Then they can find where you are.

The earliest satnav system is the Global Positioning System(GPS) of the United States. The US has put 24 satellites into space to make sure GPS can locate(定位) a person correctly and globally. Likewise, Russia's GLONASS and European Union's Galileo can also work globally.

    But China is catching up, building its own BeiDou Navigation Satellite System. BeiDou is China's homegrown satnav system, reported Xinhua. It was set up in 2000, when China sent BeiDou's first navigation experiment satellite into space. With it, China became the third country to build a satnav system after the US and Russia.

    BeiDou can find you wherever you are. It helps you go faster by finding shortcuts(捷径) and using correct directions. When you are in trouble and call the police, they will know exactly where you are if you have a cellphone that uses BeiDou.

    Today, there are more than 20 BeiDou satellites above our heads. And the system is able to offer open services to the Asia-Pacific region(亚太地区).

    In November, China plans to send more BeiDou-3 satellites into space. BeiDou-3's position accuracy(准确度) is less than five meters, Ran Chengqi, a senior designer of the satellite navigation system, told China Daily.

    By 2020, BeiDou is planned to have 35 satellites and begin serving globally, reported Xinhua.

    Galdwell's book, Blink, is all about first impressions and what he calls “rapid cognition（认知）”. In his own words, “It's a book about the kind of thinking that happens in a short time. When you meet someone for the first time or read the first few sentences of a book, your mind takes about two seconds to jump to a series of conclusions.”

    Galdwell points out that most scientific tradition is based on a great deal more than two seconds' thought though years of scientific study can come from a quick observation. As for rapid cognition, Gladwell realizes some first impressions don't seem to be based on anything. He noticed that Americans support taller candidates（候选人）. In fact, since 1900, only four candidates have beaten men who are taller than themselves. With this in mind Gladwell got in touch with 500 companies in the US and found that almost all of their managers were tall. Gladwell said, “That's weird. There is no connection between height and intelligence or height and decision-making…But for some reason companies chose tall people for leadership roles. I think that's an example of bad rapid cognition.”

    As an example of good rapid cognition, he tells the story of the Emergency Room doctors at Cook County Hospital in Chicago. A few years ago, the hospital changed the way they diagnosed（诊断）heart attacks. Their doctors took no notice of the patient's age, weight and medical history and gave most of their attention to a few really important pieces of information, such as blood pressure and heart rate. And what happened? Cook County is now one of the best places in the United States for diagnosing chest pain.

    Gladwell believes the power of first impressions should be studied further. “The first task of Blink is to show the fact: decisions made very quickly can be as good as decisions made slowly and carefully.”

    “When your mother scolds you, you can look elsewhere and think about other things. Just ignore her words. But remember: such a tough attitude cannot be used often.” These words are from a series of cartoons which outline skills for children to fight against their mothers. The images have created heated debate among Chinese netizens（网民）.

    Regarded as “a book for children aged 6 to 12 who are always scolded by their parents”， the cartoons, drawn by two 10-year-old Beijing girls, list over 20 skills which children can use to deal with their mothers' anger such as crying, pretending to be ashamed, fleeing into the toilet and pleasing her afterwards. Each skill is described with vivid pictures and humorous notes. The creativity of the young girls has amazed netizens, the Yangtse Evening Post reported on Thursday.

According to one of the girls' mothers, her daughter once received a poor mark in an exam, and the mother blamed her and compared her performance with another classmate. The daughter's feelings led to her creating the cartoons. The girl's father, who first posted the pictures on his Sohu Microblog on Monday, said he hopes parents pay close attention to the pictures, allow children to feel free to develop their own characteristics and try not to criticize them so often.

“The cartoons, although an individual case, reflect a modern phenomenon and some of the problems within Chinese family education,” said Yu Qinfang, an expert on family education. According to a survey of 104 children and their parents, Yu discovered that as many as 51.9 percent of primary school students hate being urged to do things by their mothers. “Not giving children enough time and hurrying them to do things seems to be a very tiny detail within family life, but it is potentially a huge problem which can easily be ignored by parents. A mother's blame may lead to negative feelings within her child's heart,” Yu said. “Parents should learn to blame less and be more patient.”

    When I was three years old, I couldn't speak. It was a strange reality that none of the doctors I visited could understand.

    One day, I was shadowing my mother. She found herself looking in a mirror, and through it our eyes met. She began to speak to me through the reflection, and I slowly began to mimic(模仿)her mouth's movements until I formed a word.

    It turned out I'm deaf in my left ear, and have a slight problem in my right. Being hard of hearing has been difficult, but I've never lived in a state of self-hating sorrow. Imagine being able to shut out all sound as you lay your head down to sleep by simply rolling over onto one side. That's my reality when I sleep on my "good ear", and it makes me feel like a superhero sometimes.

    People call my deaf side my "bad ear", but when I wear my hearing aid, I have access to a range of features that some other deaf people don't. In cinemas, for example, with one click of a button I can enjoy a whole film as though it were whispered to me from the mouths of the actors.

    Owning a hearing aid hasn't always felt good, however. On the first day I got my aid, when I was eight, I took it to school for show-and-tell. As I explained how it worked to my classmates, a boy yelled out, "Aren't those for old men?" At that moment, I felt different. It took a long time for me to get over that sense of being so unlike my peers.

    But it's not just school kids who can make us deaf and hard-of-hearing people feel like burdens. Every video on social media that lacks subtitles(字幕), for example, means an entire community of deaf people is unable to enjoy it. Completely deaf people are excluded from enjoying many movies too, as subtitles in cinemas are almost impossible to find.

    And with hearing aids costing around $2,500 each, it can be hard for many people to afford to be able to listen to the things that others take for granted. As for me, I can listen to music, enjoy films, and catch conversations - I'm lucky. I'm deaf, but I can still hear everything. I've been blessed with wonderful life experiences, and I am human. And when it comes to sleeping, I'm even superhuman.

    The family of a 6-year-old adopted Chinese girl who badly needs a bone marrow transplant (骨髓移植) believes they have found a match in China.

    Kailee Wells suffers from a serious aplastic anemia (再生障碍性贫血), which prevents bone marrow from producing new blood cells. She has taken courses of treatment but has shown little sign of recovery.

The best help for such patients is a transplant of healthy marrow or blood cells from a suitable donor. Certain tissue of the patient and the donor must match.

    Kailee's mother, Linda Wells, made her second trip to China earlier this month to find a donor. Her husband, Owen Wells, said that his wife believed doctors there had found a match.

     “For these last 22 months, we've been living in fear that Kailee would take a turn for the worse and there would be nothing we could do about it,” he said. “Now we have something we can use and save our little girl. We are just about ready to start jumping up and down and rejoicing.”

    Wells said a Chinese girl who is about a year old has a blood sample that matches Kailee's perfectly. The next step, he said, would be to make sure the sample is safely harvested and protected for transplant, the details of which have yet to be worked out.

    Linda Wells first traveled to China in February to try to locate the girl's birth mother, who is likely to be a match. But she found no relatives and decided to try again this month.

    “This gives us so much encouragement because now we found what we thought we would never be able to find for Kailee,” Owen Wells said. “We're going to continue our blood donor drive to try to continue to help as many people as we possibly can. We're just so happy.”
