People are being lured(引诱) onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

    Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.

    The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends' names—were set, by default(默认) to be shared with everyone on the Internet.

    According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a “less satisfying experience”.

    Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends?

    The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set principles for social-networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，” Schrage admits.

    I suspect that whatever Facebook has done so far to invade our privacy is only the beginning, which is why I'm considering deactivating (撤销) my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That's too high a price to pay.

    The Taj Mahal(泰姬陵) is a love story, a sad and beautiful one. If it didn't exist, we would easily imagine that the story of its construction was simply a fairy tale.

    Three hundred years ago, there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was Mumtaz Mahal: its shortened form Taj Mahal, means “pride of the palace”. In the year 1630 this beloved wife of the emperor died. He was so broken-hearted that he thought of giving up his throne(王位). He decided out of his love for his wife to build her the most beautiful tomb(墓穴) that had ever been seen.

    He invited the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was completed. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahal, one of the most beautiful buildings in the world.

    The building itself stands on a marble platform, 29 meters' square and 6-7 meters' high. Towers rise from each of the four corners. The Taj itself soars another 61 meters into the air. It is an eight-sided building made of white marble.

    The emperor planned to build an identical tomb of black marble for himself on the other side of the river connected by a silver bridge. However, his son put him into prison in the palace before he could finish, and for the rest of his life, he could only gaze across river at the tomb of his beloved wife.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although bosses publicly praise the broad benefits AI will bring very much, their main interest lies in cutting costs. One European bank asked a technology company to find a way of reducing the staff in its operations department from 50,000 to 500. This special report has shown that AI-enhanced tools can help reduce staff in departments such as customer service and human resources by a large amount. The McKinsey Global Institute finds that by 2030 up to 375m people, or 14% of the global workers in companies or countries, could have their jobs automated away. Bosses will need to decide whether they are prepared to offer and pay for retraining, and whether they will give time off for it. Many companies say they are all for workers developing new skills, but not at the employer's expense.

    A second important question is how to protect privacy as AI spreads. The Internet has already made it possible to track people's digital（数字的）behaviour in extremely small detail. AT will offer even better tools for businesses to monitor consumers(客户) and workers, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised（个性化的）service. But AI probably brings privacy violations (侵犯) that are seen as shocking and morally unacceptable. In the wrong hands, useful technology could be against fair and equal treatment. Countries with a record of the careful watching of a person place, especially by the police or army and human-rights abuses already using AI to monitor political activity. The police around the world will use AI to spot criminals, but may also look on ordinary citizens secretly, in order to discover things or find out information about them. New rules will be needed to ensure agreement on what degree of monitoring is acceptable.

    The third question is about the effect of AI on competition in business. Today many firms are competing to provide AI-enhanced tools to companies. But a technology company that achieves artificial intelligence could race ahead of competitors, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

    A trip to Paris is not complete without a visit to the Eiffel Tower. To get the most out of your visit read our tips below:

    Visit at Night

    Riding up the Eiffel Tower at night and looking out over the streets of Paris, you'll see why Paris is known as the “City of Light”. At street level, the spotlights on the top of the Tower and the reflections (倒影) of the Tower in the Seine (塞纳河) are sights not to be missed.

    Purchase (购买) Your Ticket in Advance Online

    Avoid the long ticket lines at the Eiffel Tower by purchasing your ticket online from the Eiffel Tower website.

    You'll pick a time to visit and then select whether to print out the ticket or display it on your phone or iPad, a convenient choice if you buy your ticket in Paris without a printer.

    Don't Bring Valuable Objects with You

    Before entering the Eiffel Tower, your bags will be examined by a security officer. If an item you are carrying sets off the metal detector, the officer will take you away from the line for further inspection. Probably you will miss the chance to go up the Eiffel Tower.

    Have Drinks and Snacks at the Eiffel Tower

    If you're like us, after an exciting trip to the Eiffel Tower, you'll be ready to rest your legs and have a relaxing snack and a drink in a Parisian cafe. Across the Seine in the Trocadero area, there are many elegant cafes. The atmosphere is great, but the prices are in the stratosphere (极高水平). Actually, the perfect place for common visitors to eat and drink is on the Eiffel Tower itself.

    A retired United States soldier named Terry McGlade, who had served in Iraq and Afghanistan, his dog Major is a hero. He is specially trained to says sense when McGlade is about to have a seizure, get his phone and dial 911 for help.

    When Major had recently sensed an incident about to happen, and McGlade collapsed and hit the floor, Major was able to get to McGlade's phone, and more or less bite on the phone which is specially set up so that when multiple buttons are pressed and held in, it goes into emergency call mode, and dial 911.

    "He was actually able to get my phone out of my pocket," McGlade said.

    The 911 operators who got the call from Major said they never heard him bark or anything. However, they could hear what sounded like a confused man in the background, and did get quite suspicious after quite a few calls from McGlade's cell phone kept coming in. Quite clearly, Major was using his leg and also stepping on the screen to get the phone to díal for help.

    After Major was sure someone would be on their way to help, he then made his way out to the front of the house to wait. When police and ambulance arrived, he led them into the house and right to McGlade, still in distress.

    "I probably would have been in severe trouble if he wouldn't have called," McGlade said.

    McGlade was taken to the hospital, where he was kept overnight for observation, but thanks to his best friend, and now hero of the day, Major. He is feeling much better, and will make a full recovery with little risk of lasting damage from this particular incident.
