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.

    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.

    Pakistan should be everyone's tourist destination for 2018, but what if you already live there?

    Then perhaps you should consider visiting these five must- visit places for the new year.

Lake Saiful Muluk

    At an altitude of 3, 224m, surrounded by now mountains, the lake rewards those that make the three-hour uphill walk from Naran. You will find the pathway just above the free market, but there is a superior option to get a jeep and split the costs with some other tourists; expect to pay about 700 rupees, worth it to view this natural beauty.

Deosai National Park

As another high point in Pakistan, it has an average altitude of 4,114m — the Deosai Plains are one of the highest plateaus(高原 )in the world. If you make it to the park, you expect to find rich plants and wild animals. The breathtaking scenery on show at the plains is enough to make 2018 a memorable year.

Naltar Valley

Accessible via a 2.5—hour drive from Gilgit, well worth visiting. Covered with pine trees and other plants, it has a dreamlike feel about it. Various colors all year around make you fall in love.

Shangrila Resort

    Right in the north of Pakistan in the Central valley of Gilgit-Baltistan. Locals call this a paradise(乐园）,and that's what it feels like. No visit is complete without checking out the restaurant which is built in the structure of an aircraft.

Rama Meadow

    Doesn't feel like Pakistan at all, more like somewhere in Minnesota. Watch the sheep and cows feeding while clear water flows in streams from high in the mountains. Against Chongra's ice-covered peak, this little meadow is a piece art.

    Wedding is one of the most universal traditions in the world. But it's celebrated differently by people around the world. Now let's know something about these traditions.

       In Jamaica, weddings are a community affair, with the whole village often coming together to help plan the big day. People in the village gather in the street to see the bride and if she isn't in perfect shape, she will be publicly criticized. And while women wear the typical white wedding dress，men wear a bush jacket for the event. Several cakes are baked for the ceremony and on the wedding day married women wearing white dresses carry the confections (甜点) to the wedding. The reception is often held at the groom's house, in a booth specially built for the event. The wedding celebration also includes a lot of dancing.

    In Welsh wedding tradition, a man carves a spoon out of wood and gives it to the woman he loves. H she wears it, they are engaged (订婚）. Brides are often hidden by their families just before their wedding day. The groom and his family follow and whoever finds her will be the next to get married.

    In her bouquet, a Welsh bride carries a small tree with shiny green leaves and white flowers that smell nice as a symbol of love, and gives a cutting of the plant to her bridesmaids as well. If the bridesmaid plants the cutting in her yard and it blooms, she will soon marry, according to Welsh tradition.

    In Czechoslovak, before the wedding, the bride's friends traditionally plant a tree in her yard and decorate it with colored ribbons and eggshells, because, according to the legend, the bride will live as long as the tree. Before the marriage vows, a baby is placed in the couple*8 bed to bless their fertility. During the wading ceremony, Czech women surround the bride*, dancing and singing. They then remove her veil (面纱）and make her put on a handrnade babushka ( a woman's head scarf).

    Imagine you're standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

    Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

    In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine." Biometrics is ideally good in practice, not so much," said John Michener, a biometrics expert.

    When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. "The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.

    "We may expect too much from biometrics," Anil Jain, a computer science professor at Michigan State University, told CBS News. "No security systems are perfect."

    Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."
