How I Turned to Be Optimistic

    I began to grow up that winter night when my parents and I were returning from my aunt's house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.

    I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.

    The four years that followed taught me the importance of optimism (乐观), but the idea did not come to me at once. For the first two years in New York I was really lost-having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex (复杂的) for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times.”

    My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.

    From my experiences I have learned one important rule: almost all common troubles finally go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.

    Kenya-Giraffe Conservation

    Preserve and protect Kenya's Wildlife

    After some difficult years, Kenya is back in fashion and welcoming travellers with open arms, with one main aim—help save and protect their unique wildlife. It isn't just the elephant under threat, but it's the smaller species that are also suffering, for example, Rothschild Giraffes. Now there are only 670 left in the wild and they need your help to survive.

    How can you help?

    Head out to the Soysambu Conservancy, which is home to more than 450 bird species and over 50 different mammals, including lions, zebra and more than 100 critically endangered Rothschild's Giraffes.

Get stuck into general reserve conservation but primarily focus on the research and protection of their resident Rothschild Giraffes, which is the reserve's main priority.

    Your Daily Tasks

    Work will be a combination of observational research and hands on work—five days a week.

    Minimum number of weeks is 2. This project is perfect for anyone with a passion for nature, wildlife, and the great outdoors.

    No previous conservation experience required.

    Where will you live?

    You will stay in the houses right in the middle of the reserve with other volunteers.

    The weekends will be free time, so you can explore further up the Rift Valley, Lake El-menteita itself and beyond.

    Lately a popular eight-floor bookstore in Hefei,Anhui province,has risen to fame because it becomes the world's first shared bookstore,in a move meant to encourage more reading among Chinese citizens.

    It comes to people's attention as more than 200,000 visitors flooded the store on its first day as a shared bookstore on July 16 this year,a record high since it was reopened to the public in 2013.Some 4,000 books were brought home on the first day,Thepaper.cn reported.

    Customers are allowed to borrow up to two books valued under 150 yuan per visit after registering with an app and paying the 99 yuan deposit fee（押金）.

    All books on sale in the bookstore are available for sharing.Returned books that are damaged are sold at a discount.The bookstore also provides a bonus for bookworms.People who finish reading 12 books in three months receive eight percent of their deposit back,and members can be rewarded one yuan for every book read.

    "We want to bring down the cost of reading so people could read more books,"Xu Xinwei,who helps run the bookstore,told Thepaper.cn.

    Some parents buy a lot of books for their children,but they usually end up collecting dust as their children grow up.Similarly,some popular novels for young people also fall out of fashion,according to Xu."Books are more effectively circulated when they're shared."

    A Spanish company Siesta&Go has opened the first public napping (小睡) space in Madrid. It promises people a quiet rest in the middle of the city's business center.

    Napping spaces are nothing new; places to rest are already set up in other big cities in the world. But the idea would appear to work well with the culture of Spain, where people traditionally take an afternoon nap, called siesta.

    The Madrid nap space recently opened with 19 beds. People can use them by the minute or by the hour, and they can also choose either a private or shared room. An hour of napping inside a private room costs about $15.

    Siesta &Go provides all bedding, clean nightshirts and other materials. Nippers can request to be woken up when their time is up. It also offers areas to work, with armchairs, newspapers and coffee for those not wishing to sleep.

    Philip &Go is one happy customer. Marco says he gets tired during the day because of hard work. He says a siesta is the perfect way to build up energy. "I come for about 30 minutes or something like that. That is usually enough for me to be full of energy."

    While many Spanish people love their naps, others like Carlos Villarroja say they are just too busy to keep the tradition. "It's a Spanish tradition, but I think it's more of a legend (传说) than a tradition. Because of the lifestyle and the working hours, we have very little free time for a siesta at least during the week."

    But many health experts believe there is evidence that taking a short nap can be very good for the body and mind. Scientific studies show that taking a siesta can also prevent illness and lower blood pressure.

    Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.

    In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢体). This makes coordinating (协调) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.

    Another interesting characteristic of bat flight is the way in which bats land-upside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.

Preparing Cities for Robot Cars

    The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

    While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

    Do we want to copy—or even worsen—the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport—an unwelcome side effect researchers have already found in ride-hailing (叫车) services.

    A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

    Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
