Your next car might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

    Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（统治的）are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

    Driverless cars will reduce accidents by around 90 percent. That's big—the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

    On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

    Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

    A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.

    In the latter part of the 20th century, child labor remains a serious problem in many parts of the world. Studies carried out in 1979, the International Year of the Children, showed that more than 50 million children below the age of 15 were working in various jobs often under dangerous conditions. Many of these children live in underdeveloped countries in Latin America, Africa, and Asia. Their living conditions are crude and their chances for education small. The poor income they bring in, however, is necessary for the survival of their families. Frequently, these families lack the basic necessities of life—adequate food, decent（得体的、合适的）clothing and shelter, and even water for bathing.

    In some countries industrialization has created working conditions for children that are comparable to the worst features of the 19th-century factories and mines. In India, for example, some 20,000 children work 16-hour days in match factories.

    Child-labor problems are not, of course, limited to developing nations. They occur wherever poverty exists in Europe and the United States. The most important efforts to eliminate（根除）child-labor abuses throughout the world come from the International Labor Organization (ILO), founded in 1919 and now a special agency of the United Nations. The organization has introduced several child-labor conventions（规定）among its members, including a minimum（最低）age of 16 years for admission to all work, a higher minimum age of specific types of employment, compulsory（强制的）medical examinations, and It depends on voluntary obedience（服从）of member nations.

    As self — driving cars come closer to being common on American roads, much of the rhetoric (说辞) promoting them has to do with safety. About 40,000 people die on U. S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous vehicles aren't car companies looking to improve the safety of their existing products. Huge backing for self - driving technologies is coming from Silicon Valley giants like Google and Apple.

    Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technological push. In this case, it's clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive (动机) to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data - and often money - to tech companies.

    At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving - as has happened in virtually every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an antomobile in which continuous cellphone use no longer poses a threat to anyone.

    In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it's around four hours a day for the average adult in the U. S. However, that rapid growth is likely to slow down as people run out of time that ' s available for them to use their devices. Unless, of course, there's a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizable opportunity for increased cellphone use.

    So as the public conversation around autonomous cars highlights the safety advantages, don't forget the tech industry ' s powerful desire for more profits, which goes well beyond simply saving us from ourselves.

    Fikiri Kiponda's path from accountant to marine (海洋的) conservationist was sparked by a chance encounter.    After securing his dream job, Kiponda decided he wanted more. He wasn't quite sure what he was looking for until he ran across some turtle hatchlings.

    He didn't know it was turtle. Fortunately enough he got the right person to ask and he got motivated. That person was Nkindi, a staff member at the Watamu Conservation project who later invited him to volunteer on the project. He later left his accounting job and fully devoted himself into the world of sea turtles. Now，he runs and spends his time nursing critically endangered sea turtles back to health.

    Sea turtles have been around for nearly 110 million years and are now considered highly endangered. Their preservation rests on activities of conservationists such as Kiponda as these turtles face numerous threats and signs of their extinction in the next 50 years.

    Local fishermen traditionally catch them to supplement their own low catch rates and sell them for their oil. As changes are made to accommodate more hotels for tourists, there is less available beach land for turtle nesting.

    Kiponda's passion has now spread to his community, changing their attitude towards sea life preservation with his “by-catch release programme.”

    Through this program, fishermen are now paid for returning turtles accidentally caught in their fishing nets. The healthy ones are tagged and released into the marine park while he takes care of sick and injured turtles back to health.

    Before the launch of pioneering spirit like this, turtles caught by fishermen were used for their meat and their oil extracted (提炼) for its medicinal properties.

    “Releasing the turtle back into the ocean is a very good feeling, like, you feel like you've done something concrete and I guess everybody would love to do that...so I guess it's unique work.”

    Since 2013,Torobo, a robotic are designed to test the limits of artificial intelligence, has had one ambition—to be admitted to the University of Tokyo, one of Asia's top-ranked educational institutions. Although equipped with an extensive database of textbooks and other teaching materials, Torobo has repeatedly failed to obtain the university's required minimum 80% score in the National Center Test, a yearly standardized entrance examination adopted by Japanese universities. This year was no exception.

    In early November, Torobo, along with millions of Japanese high school students, took a mock(模拟的)exam to prepare for the all-important standardized test.

    Torobo's total score of 525 out of 950, which was higher than the national average, was enough for it to get admitted to many other influential Japanese universities.

    However, its standard score of 57.1%, though 14 points higher than in 2015, still fell short of the minimum required for the University of Tokyo.

    A closer analysis of the results showed that Torobo was able to draw from its database to solve knowledge-based questions and ones involving complex mathematical calculations, but it had a hard time thinking independently, failing to comprehend multiple sentences and phrases to arrive at the logical conclusions. This weakness was reflected in its shabby English scores.

    Fortunately, the robot's creators have decided to free Torobo from its four-year sufferings. Noriko Arai, professor of the University of Tokyo who heads the team, says, “From the present results, we are able to evaluate the possibilities and limits of artificial intelligence. From now on, we will grow its abilities in the fields where it is doing well and aim to improve them to levels that can be applied in industry.” So while Torobo will never graduate from the University of Tokyo, it can still look forward to a bright future!

A donation letter is what you write to a person you expect, who will give away some of his money to support your good cause. Good as the cause may be, it is hard to make a person part with his hard-earned money. It takes some really great writing skills to write such a letter.

The donation letter for charity isn't exactly a formal letter for business communication. You need to take a casual tone. Make sure that you know the name of the recipient (收信人) to sound more like a friendly gesture. The language too should not be extremely serious and should be slightly informal, which can make your recipient willing to believe you.

Make sure that you include all the details regarding your program, your funds required, and your plan in the letter. The most important thing is to mention how someone stands to benefit because of the recipient's contribution. Talk about how many lives your charity fund has been able to change and how many more you wish to change further. This may touch the reader and talk him into making a donation towards your cause. Include the amount which you expect the recipient to donate, within your letter.

A typical donation letter is often divided into four paragraphs. The first paragraph will be an introduction to your organization, like what you do, how long you have been running, and your achievements. The second paragraph will give more details regarding your current goals that you're trying to reach. In the third paragraph you use a more direct method here, asking politely for any help. Keep it short and clear. The final paragraph is your conclusion, where you tell exactly how the help received would be put into good use. Add a "thank you" for any and all help received.
