NEW YORK－Australian mining enterprise Clive Palmer on Tuesday unveiled(公布)blueprints for TitanicⅡ, a modern copy of the doomed ocean liner, although he didn't call the ship unsinkable any more.

    The ship will largely recreate the design and decoration of the fabled original, with some modifications to keep it in line with current safety rules and shipbuilding practices, and the addition of some modern comforts such as air conditioning, Palmer said at a press conference in New York.

    The three passenger classes, however, will be prevented from mingling(混杂), as in 1912, Palmer said. “I'm not too superstitious(迷信的).”Palmer said when asked whether recreating a ship best­known for sinking was tempting fate.

    White Star Line, the operator of the original ship, had said the Titanic was designed to be unsinkable. About 1, 500 people died on Titanic's maiden voyage in 1912 from Southampton to New York after the ship collided with an iceberg in the North Atlantic.

    Palmer, who created the company Blue Star Line last year, refused to make a similar boast.

    “Anything will sink if you put a hole in it, ” Palmer said. “I think it would be very cavalier to say it.”

    Unlike the original, TitanicⅡwill have more than enough space in its lifeboats for every person on board and will have additional escape staircases. Markku Kanerva, sales director at Deltamarin, the Finnish company designing the ship, said it would be the “safest cruise ship in the world”．

    Palmer refused to answer questions about the project's cost. Although the Titanic was the world's largest ship in her time, she would be smaller than many of today's modern cruise ships.

    “It's not about the money，” Palmer said. “I've got enough money for it. I think that's all that matters.”

    Forbes estimated Palmer's net worth to be $795 million in 2012.He describes himself as a billionaire.

    TitanicⅡwill be built by Chinese state­-owned CSC Jinling Shipyard, which has already built four ore carriers for Palmer's mining business, he said. The contract to build TitanicⅡhas not yet been signed, Palmer said.

    Reports tell us that Americans work more and vacation less than people in other major industrial countries. Still, millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.

    For example, many retired Americans can be found driving around the United States in big recreational vehicles, known as R. V.'s. These serve as a home away from home. In fact, it might even be their only home as they see the country.

    Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There, they can experience what life was like for early Americans. If that is not exciting enough, also in Williamsburg is a water park and an amusement park with rides.

    Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing, except maybe read a book.

    Some families fly to other countries on vacation. Or they go on a cruise ship (大型游轮) and stop in different ports. Cruise ships are like floating cities.

    But not everyone goes someplace special on vacation. This might be the only time for people to work on things like home improvement projects. And while they do that, they might think of all the fun their friends are having.

    If you think you have two left feet but would love to be a good dancer then why not try your hand at dancing?

    That's exactly what I did five years ago and I immediately fell in love with dancing. To me, dancing is a magical experience: I've become fitter, look younger and feel more confident. I enjoy it so much that I will never give up this healthy pastime.

    It's very sociable as well. You meet people and make new friends while dancing the night away. Haven't you heard stories about how dancing inspired new romances or rekindled (重燃) old ones? My friends Joe and Rena just had their big day a few weeks ago after they met each other at a Ceroc workshop some three years before.

    The word “Ceroc” comes from the French language. Without the complicated footwork, it is easier to pick up by beginners. Another good thing about Ceroc is that while it is a partner dance, you don't have to bring a dancing partner.

    Other popular styles of dancing in the UK include ballroom, belly dancing, lindy hop, salsa, tango and tap dancing, just to name a few.

    No matter what types of dancing you do, one thing is for sure: you will become fitter. For office workers like me, dancing is good cardio exercise after a long day sitting in front of the computer screen. It also strengthens your muscles, improves your coordination(协调) and increases your physical confidence.

    Few people will end up being queens of the dance floor. The aim is not to win a competition but to enjoy the interaction(交流). As long as you do the right moves, keep the rhythm and most importantly keep an encouraging smile to your dancing partners, you will always be a winner!

    It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name "hackers".

    Police arrested a few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades.

    As hackers gained experience, they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline's computer to give him free airplane tickets.

    The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into.

    In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime.

    The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.

    The U.S. government believes foreign governments have hired hackers to try to break into top-secret defense computers.

    Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most outstanding minds in the U.S. will be working to frustrate the attempts of computer hackers.

    The idea behind Facebook is to make us feel connected all the time. But in my research, I've found that the truth is quiet different.

    Technology, it turns out, has made being alone seem like a problem that needs soling. When young people are alone, even for a minute or two, they feel the need to connect to get on Facebook or some other social networks and chat. But in connecting, they often end up feeling more isolated. Why? Because by being in constant (不断的) connection, they lose the ability to feel satisfied with their own company (独处).

    Facebook can help us keep in touch with our friends, but we too often use it instead of spending face to face time with them. And since we feel the need to keep up with them online, we don't have moments of loneliness where we can collect our thoughts and learn how to be comfortable being alone.

    Facebook connects more of us to more of our friends and family in more places than we have ever been connected before. Yes. Facebook is a huge time sink -maybe the biggest ever. Many people post useless stuff. And seeing too much of your friends lives can make you jealous (嫉妒的), but it won't make you lonely.

    Jane, a former student of mine, who is back in New York after living abroad for ten years told me that Facebook helps her a lot. The first time she moved back to New York from abroad, she felt disconnected from her family and friends. now because of lots of photos and information updates (更新), she knows what is happening with her friends all the time.

    In fact, if you are lonely in real life, you will be lonely online as well.
