NEW YORK—Australian mining enterpriser Clive Palmer on Tuesday unveiled(公布) blueprints (蓝本) for Titanic Ⅱ, 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 best-known 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(漫不经心的) to say it.”

    Unlike the original, TitanicⅡ will 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.

    TitanicⅡ will 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 TitanicⅡ has not yet been signed, Palmer said.

    Every pet owner loves his pet. There is no argument here.

    But when we asked our readers whether they would clone their beloved animals, the responses were split almost down the middle. Of the 228 readers who answered it, 108 would lone, 111 would not and nine weighed each side without offering an opinion.

    Clearly, from readers' response, this is an issue that reaches deeply into both the joy and eventual sadness of owning a pet. It speaks, as well, to people's widely differing expectations over the developing scientific procedure.

    Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope a clone could never truly recreate a pet, many simply didn't wish to go against the natural law of life and death.

    Both sides expressed equal love for their animals. More than a few respondents owned “the t dog/cat in the World”. They thought of their pets as their “best friend”, ''a member of the family,” “the light of my life.” They told moving stories of pets' heroism, intelligence and selfless devotion.

Little wonders the loss is so disturbing—and the cloning so attractive. “People become very lose to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of Goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away... It's understandable. Death is always painful. It's difficult to deal with. It's hard to accept.”

    But would cloning reduce the blow? This question seemed to be at the heart of this problem.

    During his freshman year at Mission Viejo High School in the United States, Chance Blanscet told his parents he wanted to score a touchdown (触地得分) for the Diablos football team.

    Born with dwarfism (侏儒症), Blanscet, now 16 and a sophomore (高二学生),

doesn't have the size of a football player, but his courage more than enough makes up for this. On May 19, Mission Viejo High's cheerleaders called Chance's name as he seized (抓住) his opportunity.

    Taking a hand-off (传球) from the receiver, Blanscet raced toward the end zone as fast as he could, while his teammates created a path for Blanscet straight across the goal line.

    After scoring his touchdown, the players lifted him up and celebrated.

    Blanscet spent the first six years of his life in local hospitals before getting adopted (收养) by parents Andy and Michele Blanscet.

    When they brought him home, he couldn't speak and could only walk with the help of a walking frame (助行架). But as he grew older and stronger, he needed less medical attention.

    Blanscet was received with open arms at his high school and became interested in football after attending the first game of his freshman year.

    After meeting Diablos head coach Bob Johnson, he was eventually asked to lead the team's junior squad (小队).“This is an amazing group,” Michele Blanscet said. “They're so supportive. They view him for his abilities, not his disabilities.”

    Blanscet's video class filmed the entire event, from Blanscet leading the team to his post-touchdown celebration. And instead of shouting “Diablos,” the players shouted “Chance”.

    That's a thing of a lifetime,” Johnson said. “He tries to make it to every game. This is just a special thing they wanted to do for him.”

    The scenes will be used for a video Blanscet is working on for class. It will also include highlights of football games from last fall, and interviews with players and cheerleaders.

    “We needed something big to go with it,” said Marty Deutschman, who has been Blanscet's one-on-one instructor (教员) for three years. Deutschman organized the event about a month ago.

    Everyone was immediately on board. “We're so impressed with the school spirit,” Andy Blanscet said. “The students are there for each other and they were able to put together such a big event in a short time with all that enthusiasm.”

    My sister and I were flying by ourselves from our home in Kansas to a summer camp in Minnesota. Our plane had a two-hour stop at the airport in Omaha, Nebraska. A flight attendant took us to a souvenir shop, where a toy airplane looked just like the plane my sister and I were flying on. I really wanted that airplane. I had $10 and the plane cost $8. I had no idea what I needed to buy at camp, but I bought the plane anyway. When we reached the camp, I discovered that there were no showers! Instead, we bathed in a lake every night. I needed to buy special soap because the regular soap I brought had chemicals that could harm the fish. The special soap cost $4 at the camp store. However, I had only $2 left.

    What upset me was that I couldn't get clean without the soap, which was soon found by my teacher, Sally. I had to tell her that I had spent most of my money on a toy airplane. She laughed and explained to me that a budget was necessary and it was a plan for spending money to help make sure you set aside enough for things you need, like soap, before you buy fun things, like toys.

    Sally gave me one of her extra(额外的) bottles of special soap. When I returned home, I decided to budget. I spent several weeks writing down everything I bought, just to get an idea of how I was already spending my money. Then I made my first weekly budget. My budget wasn't always the same each week. For some weeks, I would have more in my “Money In” account because I did some jobs around the house. Once summer vacation started, I didn't need to buy school lunches, so I had extra money to go to the neighborhood swimming pool or to give to the town animal shelter.

    Budgeting was hard, sometimes. Whatever week it was, I always made sure that “Money In” equaled “Save and Spend.” That's called making ends meet, and it's how you make sure that the money you have will always be enough to cover your plans to spend and save.

    When my daughter Sara was in the fifth grade, she came to me with a problem." Marcy hates me！" she cried." Because Kathy is my friend, too. She wants me to be her friend and nobody else's. You talk to Marcy. You tell her that I want to be her friend, but I can have other friends, too！"

    Oh！I looked at her for a few moments，wondering how I got into this mess，when suddenly an idea came to me.

    Picking up two baskets from the living room, I explained, "When everyone is born, he or she has a little basket. This little one here is yours. The big one is mine. As you grow, so does the basket. You can see your little basket is inside mine because when you were born, there were too many things you couldn't do for yourself. I did everything you couldn't do on your own." She nodded.

    "Well, as you grew older and began to do some things on your own, I began placing a few more things in your basket. When you learned to tie your shoes, that went in your basket."

    She said softly, "I can tie my own shoes."

    "Right. As you grow older，there will be more and more things you must do on your own." As I spoke, I gradually took her basket out of mine and handed it to her." You will finally carry your own basket with things only you can do."

    She looked up at me and said," I understand. There are some things that I have to do for myself because they are in my basket."

    A study published in the journal Science reveals that since 1970, bird populations in the United States and Canada have declined by 29 percent, or almost 3 billion birds. The results show tremendous losses across diverse groups of birds and habitats - from iconic songsters such as meadowlarks to long-distance migrants such as swallows.

    "These data are consistent with what we're seeing elsewhere," said coauthor Peter Marra, former head of the Smithsonian Migratory Bird Center. It's urgent to address ongoing threats, both because the domino effects (多米诺效应)can lead to the decay of ecosystems that humans depend on for our own health and livelihoods and because people all over the world cherish birds in their own right. Can you imagine a world without birdsong?"

    Evidence for the declines emerged from detection of migratory birds in the air from 143 NEXRAD weather radar stations across the continent in a period spanning over 10 years as well as from nearly 50 years of data collected through multiple monitoring efforts on the ground. Citizen-science participants also contributed a lot, for the analysis included citizen-science data from the North American Breeding Bird Survey coordinated by the Canadian Wildlife Service- the main sources of long-term, large-scale population data for North American birds.

    The study noted that the largest factor driving these declines is likely the widespread loss and degradation of habitat, especially due to agricultural intensification and urbanization. Other studies have documented death from predation (捕食)by domestic cats; collisions with glass, buildings, and other structures; and pervasive (普遍的)use of pesticides associated with widespread declines in insects, an essential food source for birds. Climate change is expected to compound these challenges by altering habitats and threatening plant communities that birds need to survive.

    "It's a wake-up call that we've lost more than a quarter of our birds in the U.S. and Canada," said coauthor Adam Smith from Environment and Climate Change Canada. But the crisis reaches far beyond our individual borders. Many of the birds that breed in Canadian backyards migrate through or spend the winter in the U.S. and places farther south - from Mexico and the Caribbean to Central and South America. What our birds need now is an historic, hemispheric effort that unites people and organizations with one common goal: bringing our birds back.
