The female dog, who Leonard appropriately named Gobi, joined Leonard on the second day of the annual 4 Deserts Race Series and ran side-by-side with him for 77 miles. Leonard noticed Gobi running with 101 runners during the first day, but on the second day, Gobi was on the start line, looking up at him. "This was the first contact I had with her and as I ran off the line I noticed her by my side," he said. "I didn't speak much to her that day, but at the finish line she followed me into the tent and we slept next to each other. That was it then."

    Leonard shared his sleeping space, water and food with his small companion during the race. He even lent her a hand when needed. "I carried her across rivers that she could not cross on her own," he wrote on his Crowdfunder page.

    After the race, it was clear to Leonard that he had developed a special bond with the pup and started researching ways to get Gobi to the UK. He learned that it would take four months for Gobi to be medically checked and cleared for entry, all of which will cost $6,560 USD, an amount that has been surpassed(超过) due to a successful Crowdfunder campaign that raised $13,330 USD.

    Thomas Edison received a patent(专利) for his kinetoscope(电影放映机) on August31, 1887. It was a machine for viewing moving pictures. Edison had hoped to combine his no invention with the phonograph(留声机), which he had invented 10 years earlier. He thought that people would like to watch moving pictures that went along with the sound. He was not able to make them work together. The kinetoscope, however, was a popular attraction by itself. A person looked through small holes in a box-like machine and saw pictures in action. One of the first films made showed a man sneezing.

    A problem with this invention was that only one person could view the moving pictures at a time. By 1891, Edison had invented a projector that showed the film on a screen. Many people could watch together.

    In 1893, Edison built a motion-picture studio. He made over 300 silent films. Most of them were short. That was because the pictures flashed, or shook a lot. It was hard for people to watch more than 10 minutes at a time.

    The first films were mostly of real events. They would show famous people walking somewhere, cars on a street, burning houses, and other news stories. Then comedies and short dramas were made.

    Edison's movie studio closed in 1918. By then other companies were also making films. Better cameras were made. Sound was added. Then color came along. Today, movies are among the most popular forms of entertainment.

    "A photograph that one has taken of oneself, typically with a smart phone or webcam and uploaded to a social media website" is the definition of "selfie" in the Oxford English Dictionary. In fact, it wasn't even in the dictionary until August of last year. It earned its place there because people are now so obsessed with (对……痴迷) selfies—we take them when we try on a new hat, play with our pets or when we meet a friend whom we haven't seen in a while.

    But is there any scientific explanation for this obsession? Well, you should probably ask James Kilner, a neuroscientist(神经系统科学家) at University College London.

    Through our lifetime we become experts at recognizing and interpreting other people's faces and facial expressions. In contrast, according to Kilner, we have a very poor understanding of our own faces since we have little experience of looking at them—we just feel them most of the time.

    This has been proved in previous studies, according to the BBC.

    Kilner found that most people chose the more attractive picture. This suggests that we tend to think of ourselves as better-looking than we actually are. To further test how we actually perceive our own faces, Kilner carried out another study. He showed people different versions of their own portrait—the original, one that had been edited to look less attractive and one that was made more attractive—and asked them to pick the version which they thought looked most like them. They chose the more attractive version.

    But what does it say about settles? Well, isn't that obvious? Selfies give us the power to create a photograph—by taking it from various angles, with different poses, using filters (滤色镜) and so on—that better matches our expectations with our actual faces.

    "You suddenly have control in a way that you don't have in non-virtual(非虚拟的) interactions," Kilner told the Canada-based CTV News. Selfies allow you "to keep taking pictures until you manage to take one you're happy with", he explained.

    Electric Shock

    Injuries caused by electric shock are fairly common. When a person has received an electric shock, no one should go near him/her until the current has been turned off.

    If a shock occurring at work or at home causes someone to lose consciousness（知觉）, electrical connection must be broken before anyone tries to give assistance. You should either turn off the switch at the mains or, if that is not possible, push the person away with a dry piece of wood.

    Treatment of Shock

    Look out for signs of shock. People who have been injured or who may have lost a lot of blood, or those who have had heart attacks, may be in deep shock. The signs to look for are faintness, paleness, a moist, sticky skin, shallow, rapid breathing and a fast but weak heartbeat.

    Shock can prove fatal, and it is essential to do something to prevent its developing. The best way to treat or prevent shock is to keep the patient lying down , better with the legs higher than the head; if possible, raise the lower part of the body on a rolled-up packet or similar object. Make the patient as comfortable as possible, loosening any tight clothing, and comfort him/her because fright increases the effects of shock.

    Why we cry with happiness show: Responding with a negative reaction helps us deal with extreme joy. If you cry with happiness at weddings, you are responding to a happy experience with a negative reaction. The researchers believe the unusual reaction may help renew emotional balance in us and keep extreme emotions under control. The findings make it clear how people express and control their emotions, which could help improve their understanding of people's mental(精神的) health.

    Dr Oriana Aragon set out to explore the phrase “tears of joy”, which she said never made sense to her. But after studying a series of incongruous(不和谐的) expressions, she now understands better why people cry when they are happy. “People may be renewing emotional balance with these expressions,” she explained. “They seem to take place when people are struck by strong positive emotions. People, who do this, seem to recover better from those strong emotions.”

    The report show various examples of responding to a positive experience with a negative emotion, such as, a crying wife seeing the husband returning from war again, and teenage girls screaming at a Justin Bieber concert. Examples also include a baseball player who hits a home run, only to be slapped(拍) on the back by teammates, as well as when people cannot help kissing babies' faces who they consider lovely.

    Dr Aragon and her team discovered that people, who expressed negative reactions to positive news, were able to moderate(缓和) strong emotions more quickly. There is also some evidence that strong negative feelings may provoke positive expressions. For example, nervous laughter often happens when people are faced with a hard situation. We've seen people smiling during times of extreme sadness.

    “The findings affect our knowledge of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” Dr Aragon said.

    Last night, when I went to see my grandmother, she was sitting alone at the nurse station with her word search book. My grandmother was sitting at the desk with her book but no pencil just staring at the letters as if she was trying to find the word. I came to her and said hello.

    Usually, she at least knows I am connected to her somehow but this time, she looked at me with doubt. I introduced myself and told her that I was her granddaughter. "I don't know who you are," she said." Do you want to go outside?" I asked. "okay," she said.

    We got her things and I wrapped it all in a blanket we would use as a tablecloth. I asked her if she could hold it while I pushed her wheelchair and held her cup of tea.

    She held her hands out and I placed the cloth bundle (捆) on her lap. I put the cloth on the table and she helped smooth it down-then I put the rest of the items on the cloth.

    Now she was just staring at me as if confused, as if trying to figure me out. "Do you know who I am?" I asked. She said, "I don't really know." "I am your granddaughter," I said. "I am not sure what that is. I don't know, I don't know you," she said.

    I think of my friend whose mother has not known him for years, has no recollection (记忆), and doesn't speak any more. It is a painful sight for all those living who remember. I am grateful that my grandmother is still so present. I have a sinking feeling that our days are numbered.

    For now, she is still here, still says thank you, and still loves me from a deep and secret place. Tomorrow, I will see her and she may or may not know me-and that will be okay. I still know her.
