Cleverness is a gift while kindness is achoice. Gifts are easy—they're given after all. Choices can be hard.

    I got the idea to start Amazon 16 yearsago. I came across the fact that the Internet usage was growing at 2,300percent per year. I'd never seen or heard of anything that grew that fast, andthe idea of building an online bookstore with millions of titles was veryexciting to me. I had just turned 30 years old, and I'd been married for ayear. I told my wife Mac kenzie that I wanted to quit my job and go to do thiscrazy thing that probably wouldn't work since most start-ups don't and I wasn'tsure what to expect. Mac kenzie told me I should go for it. As a young boy, I'd been a garage inventor. I'd always wanted to be an inventor, and she wanted meto follow my passion.

    I was working at a financial firm in NewYork City with a bunch of very smart people and I had a brilliant boss that Imuch admired. I went to my boss and told him I wanted to start a companyselling books on the Internet. He took me on a long walk in Central Park,listened carefully to me, and finally said, “That sounds like a really good idea,but it would be an even better idea for someone who didn't already have a goodjob.” That logic made some sense to me, and he convinced me to think about itfor 48 hours before making a final decision. Seen in that light, it was reallya difficult choice, but finally, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always behaunted (萦绕)by a decision to not try at all.

    After much consideration, I took theless safe path to follow my passion, and I'm proud of that choice. For all ofus, in the end, we are our choice.

    It's common knowledge that sleep problems can be caused by things such as stress, anxiety, or even using a smartphone before bedtime. But recently, a team of researchers discovered that genes could also be a cause of sleepless nights.

    The scientists, from Rockefeller University in New York, US, found that delayed sleep phase disorder（DSPD，睡眠相位后移综合症）, a condition that affects one's sleeping patterns, is passed down via a mutated（突变的）gene. DSPD sufferers wake up later and go to bed later than the average person. To come to their conclusion, the team studied a 46-year-old woman who is only usually able to fall asleep at 2 or 3 in the morning. It was discovered that the woman's body produces the hormone that helps her sleep at night up to 7 hours later than regular sleepers. The scientists found this was caused by a mutation in one of the woman's genes, one that helps regulate the “body clock”.

    Some of the woman's family members were also found to share the same mutation—and the same sleeping problems –leading the scientists to believe that sleep troubles are passed down through the generations.

    However, having this mutation doesn't mean you automatically have sleep problems. The team also found two people who had the mutation but reported no problems with their sleep.

    But while this is an interesting discovery, it offers no help to those who can't fall asleep at night—although there are a few things you could try to help you sleep earlier.

    BBC journalist Michael Mosley produced a TV documentary in May in which he talked about his battle with insomnia（失眠）and the techniques he used. “I avoid social media for at least an hour before bed, I do mindfulness exercises, and if I wake up in the middle of the night, I read a book for an hour or so,” he wrote in an article for the Radio Times.

    People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions — and a new report published online in Current Biology explains why.

    Rachael Jack from University of Glasgow, said that rather than scanning evenly across a face as Westerners do, Easterners fix their attention on the eyes.

    "We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, while Easterners favor the eyes and ignore the mouth."

    According to Jack and his colleagues, the discovery shows that communication of human emotions is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used reliably to convey emotions in cross­cultural situations.

    The researchers studied cultural differences in the recognition of facial expressions by recording the facial movements of 13 Western people and 13 Eastern people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, or angry. They compared how accurately participants read those facial expressions using their particular eye movement strategies.

    It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggests that while Westerners use the whole face to convey emotions, Easterners use the eyes more and the mouth less."

    In short, the data shows that facial expressions are not universal signals of human emotions. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotions. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

    Imagine possessing something that you loved so much. Imagine what it would feel like if you lost it. While that item may be something as simple as a doll, you would still feel very upset, but you could replace it with a new one. Now imagine losing something that you depend on for survival and cannot be replaced. That is what it would be like if we lost the natural environment around us.

    Firstly, I believe the environment should be preserved because it supports human life. One of the largest examples is that we get all of our food and drinks from the environment. If the environment were to be destroyed beyond revival, then the human race would be over in months. Scientists have yet to find another planet with similar conditions to the Earth, and if it's found, we don't have the technology to get to that planet on time.

    Secondly, I believe that the environment serves as an amazing educational tool for students. When I was in second grade, I had an absolute interest in animals. When we had a field trip to the Daggerwing Nature Center, I was very excited. When we got there, I could hardly believe what I was seeing. There was a bridge to get to the main building, and under the bridge was a small swamp (沼泽) with turtles, fish, and my personal favorite, alligators. I was so surprised that I almost ran into the tour guide. We walked into the building and saw various animals in their habitats. I was so inspired by this visit. Six years later, I have taken an animal behavior class for three weeks. Meeting by chance with the environment can inspire people, and if preserved it will continue to inspire people.

    In conclusion, the environment is so valuable because it can't be replaced, keeps us alive, and serves as a great educational tool.

    During an earthquake, you should know what to do. If the earthquake strikes while you're inside a house, you should lie on the floor under a strong table or other furniture. If there is no furniture, you can cover your head with your arms and keep still in the corner of the room. You should keep away from windows, glass walls, or anything that can fall.

    If you are in bed, hold firmly onto your bed and make use of a pillow to safeguard your head. You may use a doorway but only when it is close to you. It should also be considered whether it is strong enough to deal with the load.

    If you are running out, do not use lifts, even if they work. Electricity may go out at any time. Many injuries happen when people try to rush out. This means you ought to stay in your house or perhaps wherever you are.

    When you stay outdoors, you should stay far from buildings, power wires or lights. You should be in the open until the quake stops. Remember that many earthquake deaths outside the house come from falling-apart walls, flying glass and other falling things.

    If an earthquake strikes and you are driving, you should pull up to the side of the highway and stop as quickly as possible. You ought not to stop under trees, buildings or energy wires. Don't stop in the middle of the street as it could trouble others.

    When trapped, you shouldn't move. Your mouth should be covered with a piece of clothing or a handkerchief. This is because it is possible for you to breathe in some dust. Do not shout whenever possible. You should only shout in the end to get help from rescuers.

    It was the beginning of 2011. I had just finished filming the first season of Game of Thrones(《权利的游戏》). With almost no professional experience, I had been given the role of Daenerys Targaryen. The show was so successful that young girls would dress themselves up as Daenerys for Halloween.

    And yet, terrified of the attention, terrified of trying to make good on the faith that the creators had put in me, I worked much harder.

    On the morning of February 11, 2011, I was getting dressed in a gym when I started to feel a bad headache. I was so exhausted that I could barely put on my sneakers. I tried to ignore the pain, but I couldn't. I reached the toilet and sank to my knees. A woman came to help me. Then everything became unclear. I only remember the sound of an ambulance.

    That operation lasted three hours. When I woke, the pain was unbearable. After four days, they moved me out of the I.C.U. (重症监护室). But one day when a nurse asked me, as part of a series of cognitive (认知的) exercises, " What's your name?", I couldn't remember my name and I felt terrified: I am an actor; I need to remember my lines. Now, I couldn't recall my name.

    The phenomenon is called aphasia. Then I was sent back to the I.C.U. and, after about a week, I was able to speak and know my name. And I was also aware that there were people in the beds around me who didn't make it out of the I.C.U. I was continually reminded of just how fortunate I was.

    I rarely gave a thought to my health. Nearly all I thought about was acting. I thought of myself as healthy. Once in a while, I would get dizzy. When I was fourteen, I had a migraine (偏头痛) that kept me in bed for a couple of days. But it all seemed manageable — part of the stress of being an actor. Now I think I might have been experiencing warning signs of what was to come.

    Anyway, there is something pleasant about coming to the end of Thrones. And I'm so happy to be here to see the beginning of whatever comes next.
