More than 10 years ago, it was difficult to buy a tasty pineapple.The fruits that made it to the UK were green on the outside and, more often than not,hard with an unpleasant taste within.Then in 1966,the Del Monte Gold pineapple produced in Hawaii first hit our shelves.

    The new type of pineapple looked more yellowy-gold than green.It was slightly softer on the outside and had a lot of juice inside.But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world's best-selling pineapple variety, and delivering natural levels of sweetness in the mouth,up until then only found in tinned pineapple.

    In nutrition it was all good news too.This nice tasting pineapple contained four times more vitamin C than the old green variety.Nutritionists said that it was not only full of vitamins, but also good against some diseases.People were understandably eager to be able to buy this wonderful fruit.The new type of pineapple was selling fast9 and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.

    Seeing the growing market for its winning pineapple, Del Monte tried to keep market to itself.But other fruit companies developed similar pineapples.Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte's attempts to keep the golden pineapple for itself were just a way to knock them out the market.

    After ruling the tennis world for almost five years,Roger Federer is adjusting to life at NO.2.But,like any king whose throne has been taken away,the Swiss star is already planning secretly bis return to power,beginning at this week's US Open.

    The problem is, many experts think he will never do it.They blame everything from age and tough competition to his racket and psychology.

    For years Federer, had enjoyed the view from the top.Competitors saw him as undefeated,and for the most part he was.However,before the 2008 season began,Federer had an illness that stole his strength and clearly affected his play on the court.Ever since,he has struggled to return to form,winning just two of his last 14 tournaments.

    "Twenty-seven is an age when your body starts talking back to you."tennis great John McEnroe told the New York Times.

    Pancho Sefura, another tennis great, noted that Federer is also facing a maturing crop of young talents."There are too many great players now,"he said,naming Britain's Andy  Murray,21,and Latvia's Ernests Gulbis,20.

    US magazine Sports Illustrated tennis columnist Jon Wertheim suggested that part of Federer's problem could be his insistence on using a small racket.He says that the smaller head demands ball control.But we see time and again that racket makers try to get players to use a certain stick-one they would like to market to consumers and it has a negative effect on the professional game.

    Sports psychologist Jim Loehr told the Times that Federer is probably feeling "a sense of doubt"after being considered as undefeated for so long.If Federer is to recover his state of being undefeated,Loehr said he must overcome his doubt."Federer doesn't need fame and money.But he has to get better.He has to go t.o a whole new level.That's the only way he stays in the game," he said.

    As for beginning his first Grand Slam in ages as the NO.2 seed, Federer said it might be for the best."Five years almost,I was expected to win every tournament I entered,"he said,"so maybe Rafael Nadal now feels what I had to feel for a very long time.It will be interesting to see how he handles it."

    On Tuesday, scientists announced that they have discovered the bones of four settlers in Jamestown, Virginia. Jamestown was the first permanent English settlement in what become the United States. The bones were unearthed under the floor of a Jamestown church which was discovered in 2010 and is considered as America‘s first Protestant church.

    The Jamestown Rediscovery Foundation at Historic Jamestowne and the Smithsonian's Museum of Natural History announced that the settlers held high leadership positions. The men, Rev.Robert Hunt,Capt. Gabriel Archer,Sir Ferdinando Wainman,and Capt. William West, all played a role in the Jamestown settlement. After being lost to history for more than 400 years, the discovery of their remains provides new clues about their life and the importance of religion in the 1600s.

    “This is a very important discovery,” Jamestown Rediscovery Foundation President James Horn said in a statement. “These men were among the first founders of English America."

    About 100 people settled along the James River in what would become the first English settlement m 1607. During that time, settlers in Jamestown were faced with famine and disease The colony was nearly wiped out due to conflict with Native Americans in the area and with other English settlers.

    "They lived and died at a hard time in the history of the settlement , when Jamestown almost ended in  failure," Horn said. “The bones of these men help fill in the stories of their lives ”

    The Smithsonian and the Rediscovery Foundation found the remains in November of 2013. Scientists used 3-D technology to locate the exact gravesites of the men. The team wanted to identify its findings before announcing the discovery. They identified the men using historical records and studied the chemicals of the bones to learn what the men ate and where they came from.

    Findings from the burials will go on display within weeks at Historic Jamestowne. The site also plans to honor the men and will keep their bones in a safe place for future study.

    When an Indiana woman got an emergency call that her mother was in hospital, she knew she had no time to waste getting to her mom's side in Montgomery, Alabama. As she pulled over to get gas about 170 miles from her destination, the woman reached for her purse. It wasn't there. In the flurry to get to her mother's side, she'd left her handbag at home, along with her wallet and phone.

    The woman felt totally at a loss. Desperate for help, she asked for help in a truck stop. Someone sent her up the road to Jim Oliver's Smoke House, a restaurant known for its generosity. In fact, it's even been nominated (提名) as one of the Nicest Places in America.

    In the parking lot of the restaurant, the woman broke down telling her story to the owner, James Oliver. He listened patiently, checking her car for an Indiana license plate and deciding whether he should believe her. To her astonishment, he handed her $200 in cash. In hopes of calming her down, Oliver offered her a meal, which she took to go so she could get back on the road.

    Handing hundreds of dollars over to a stranger might seem crazy to some people, but to Oliver, it's common sense. He figured a tank of gas alone would cost $75 or so, and she'd need more money for a motel room and food before she could work things out with her credit card. “I instinctively (本能地) went for $200,” he says. “I didn't think of getting it back.”

    The Smoke House has had a reputation for kindness ever since Oliver's dad, the original owner, was in charge. In addition to helping travelers in need, Oliver's father was involved in the community by helping to establish a state park, daycare, medical center, and more. “Growing up, he instilled (灌输) in us to help other people,” says Oliver.

    The Smoke House might look like a business, but it's a charity at heart. “When you've got food, you can't turn people away that need help,” says Oliver.

    A conference was held with former technology industry leaders calling for urgent measures to protect children from smartphone addiction (上瘾).

    Among those urging major changes is Tristan Harris—a former high-level employee at Google. He just launched a group that will seek to gather and publish evidence of how digital devices and social media can harm children and young people. Harris says he believes companies like Google, Facebook and Apple have a "moral responsibility" not to create technology products that can "hijack how the mind works".

    The conference where Harris spoke was sponsored by Common Sense Media, a child and family activist group. The organization says research suggests that half of all teenagers feel addicted to their mobile devices, while about 60 percent of parents believe their kids are addicted.

    The group also cites a recent study of eighth graders that found heavy users of technology were 56 percent more likely to say they are unhappy, while 27 percent more likely to be depressed. Even Facebook cited research last year suggesting that social media use can harm mental health when used in certain ways.

    James Steyer is the founder of Common Sense. He says more than half of schools in the US are already members of the organization. The group provides teachers and parents with learning materials intended to help students develop critical thinking skills and balance their digital lives.

    Some US schools, however, have tried to limit or remove technology to improve learning. One of them is in Silicon Valley, the center of the American tech-industry.

    The Waldorf School of the Peninsula does not use any computers or digital technology in its education programs up to the seventh grade. The schools' website says while Waldorf teachers recognize the role technology can play in the classroom, it must wait until the student reaches the right developmental age. Normally when students reach high school, they are allowed to use computers and digital tools in the classroom.
