Top lists are lecturing people on everything from “100 places to visit” to “100 books to read”. Aren't you just tired of being told what to do with your time?

    Now you have a list to end all lists!

    Take a look at the following two examples from the list of “101 thins not to do”:

    Swim with Dolphins?

    Swimming with dolphins is one of the world's most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded tourists, they could get caught up in ropes and killed by propellers(螺旋桨).

    Here's a little secret. Dolphins look like smiling at you, but actually they're just opening mouths.

    Go to see the Mona Lisa?

    There must be something about the mysterious smile. The 6 million people who visit the lady in the Louvre every year can't all be wrong, after all. But they can be quite annoying, standing in front of you, holding up their cameras to prevent you from seeing anything. In fact, it is hard for you to see the painting clearly because you have to stay away from it for security reasons. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds most.

    If the mysterious lady in the picture knew her fate, she wouldn't just be smiling, she'd be laughing.

    So, still long to see the Mona Lisa? If you want to find out more about the list, read 101 Things NOT to Do Before You Die. Visit www. not2dobeforeidie. co. uk and buy the book at a 20% discount.

    In a paper published in the journey Science Advance, researchers describe how Matabele ants, a species of large ant known for attacking termite colonies (白蚁群落), will, after the battle, pick up injured fellow soldiers and carry them back to the nest where they can recover.

    The paper is the latest in a growing body of research that this form of helping behavior, previously observed in some mammals and birds, may not require complex emotion, and may, therefore, be far more widespread in nature than previously thought.

    “Here we have an example of an individual saving another individual,” says lead researcher Erik Frank who conducted the research. “We can be quite certain that the ants don't know why they are doing what they are doing.”

    It's a behavior that pays off for the colony. Our classic conception of worker ants is that they are essentially abandoned, but Mr. Frank and his colleagues calculated that the practice of rescuing nest mates results in a colony size that is a 28.7 percent larger than it would be had the ants left their fellow soldiers for dead.

    “These injured ants are able to recover from their injuries, ” says Frank. “They are essential for the safety and the betterment of the colony. ”

    When a Matabele ant is injured, as often happens during battles with termites, its body will give off two smelly chemicals that tell other ants to carry it back to the nest. Indeed, the researchers found that using these chemicals to seek help from uninjured ants will effectively activate the rescue behavior, supporting their theory that the ants were acting on pure instinct(本能), not more complex emotions.

    “The more we study rescue behavior in ants and other animals, the more we are going to realize that it's not just limited to the species we've observed so far, ” says Karen Hollis, a professor at Mount Holyoke College, mentioning studies that found that dolphins help other injured dolphins to the surface for air, capuchin monkeys defend each other during intergroup battles, and rats free other rats that are trapped.

    In the summer of 1848, in Guatemala, a man called Ambrosio Tut went out into the jungle, as he did almost every day. Tut was a gum collector, looking for gum in the jungle. To do this, he had to climb the trees. One day, he got to the top of one tree and something caught his eye. He looked out across the trees and saw the tops of some old buildings.

    Tut didn't really know what he had seen but he knew it was something special. He ran to tell the local governor excitedly, and together they walked into the jungle. There they found Tikal, the city that the Mayans had built, many hundreds of years before. The two men saw pyramids, squares and houses.

    For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city. But no one had seen it for centuries. Between 200 and 900 AD, the city of Tikal had ben the centre of Mayan civilisation in the area, but then the Mayas let it—nobody knows why! After 1000 AD, the jungle began to cover it. And then people forgot that it was there.

    Seven years before Tut found Tikal, two British explorers had gone to Guatemala and had written a report about Mayan treasures in the jungle—but they hadn't mentioned Tikal. Even earlier than this, local Indians had told people about a great city hidden in the trees, but no one had listened to them. So they lost the chance to find the treasure. Now the lost city had been found again, and people went there immediately to see it.

    If you're a fan of smart technology, you may have had some sleepless nights lately.

    That's because Alexa, the artificial intelligence (AI) behind US company Amazon's Echo smart speakers, has been "letting out an automatic, creepy (令人毛骨悚然的) cackle," for no apparent reason, according to BBC News.

    Many social media users shared their stories of Alexa scaring them with the seemingly unprompted laugh.

    "Every time Alexa laughs, an angel dies," Tesla and SpaceX founder Elon Musk joked on social media.

    On March 7, Amazon released an update that fixed the problem, saying that the laugh was triggered (引发) by Echo devices mistakenly thinking that users had said the command "Alexa, laugh".

    However, what should have been a funny story raised the ongoing topic of man versus machine.

    With the rise of artificial and robotic technology, "Digital machines have started to demonstrate (展示) broad abilities in pattern recognition, complex communication, and other fields that used to only belong to human," wrote Erik Brynjolfsson and Andrew McAfee in their book The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Technologies. They believe that AI will "do more and more, and our lives will get better".

    However, ever since the earliest days of AI, there have been concerns that some day, software will take over the world, leaving the fate of humans unknown.

    "With artificial intelligence we are summoning (召唤) the demon ," Musk told students during a meeting at MIT in 2014. "If I had to guess at what our biggest existential threat is, it's probably that. So we need to be very careful."

    Many scientists have shared the same concern. The late British physicist Stephen Hawking said at a technology conference in Portugal in November that "computers can, in theory, imitate human intelligence, and exceed it… AI could be the worst event in the history of our civilization." If creators are to safely control AI, however, Hawking suggested that they "employ best practice and effective management".

    "I am an optimist and I believe that we can create AI for the good of the world," he said at the conference. "We simply need to be aware of the dangers, identify them, employ the best possible practice and management, and prepare for its consequences well in advance."

    On Sept. 19 the Westchase Elementary PTA（Parent-Teacher Association）will hold its Wizard Walk. The Wizard Walk is a locally organized, healthy alternative to traditional product sales that will raise money to support all PTA programs and events for the year. Remaining money will be applied to an on-going capital campaign to build a new playground.

    The Wizard Walk will take place on Wednesday, Sept. 28, from 8 a. m. to noon at the Westchase Recreation Center Field.  Volunteers will be needed throughout the event.  Look for more Wizard Walk information and volunteer sign-up links in your student's folder, or contact（联系）Laura Kohler at president＠ westchasepta. org.

    The PTA is also holding a year-long Spirit Stick fundraiser（资金筹集活动）. Spirit Sticks are small and students can display them on a key ring on their backpacks, which represent a variety of interests and accomplishments. There will be many ways to earn a Spirit Stick （good grades, great behavior, exceptional attendance, etc.）and opportunities to purchase the limited edition sticks for just $1 every Friday in the courtyard. For more information, contact Nikki Pivnichny at fundraising@ westchasepta. org.

    In addition to new fundraising programs, the PTA is partnering with our Guidance Counselor, Mrs. Kiersten Rivenburg, on a new campaign called Kindness Counts. Look for new recognitions and rewards as we continue to promote kindness from our children, staff and parents throughout the year.

    Every person plans to run off to some tropical isle, but few do. Real life, family, work, and monetary limitations get in the way. Ian Fleming let none of these considerations stop him.

    After the war, Fleming set down his schedule. The first week of January saw him leave England and travel to Jamaica. The first week of March saw his return. He accepted his job at Kemsley newspapers without compromise—this portion of the year would be set aside for Jamaica or he would look elsewhere for employment.

    For 6 years Fleming traveled each winter to Jamaica, lounging in paradise, romancing women, chasing the sunset, but it was not until he faced the pressure of a married woman who was pregnant with his child did Fleming start the writer's journey which would change his life and popular culture forever. As Fleming waited in Jamaica for Anne's divorce to become final, he wrote the first draft of a novel, Casino Royale.

    Fleming's career as a writer deserves more examination than can be offered here, but suffice it to say, over the next 12 years, Ian Fleming transformed his elite existence, his arrogance, his style, and his acid wit into some of the greatest thrillers ever written. Fleming incurred the respect of authors as diverse as Raymond Chandler, Kingsley Amis, and Edith Sitwell. His fans included John, Jackie, and Bobby Kennedy, and his social circle included Prime Minister Anthony Eden, Evelyn Waugh, and Somerset Maugham.

    Fleming filled out the 12 years of Bond with great adventure journalism. Even in stories which had little action or pay off, such as his short non-fiction book, The Diamond Smugglers, the "Fleming-flair" ensured exciting reading. He wrote the "Atticus" column for the Sunday Times, proving a wonderful conduit for inside intelligence information, and clever rebukes (指责).

    Regardless of book sales or family obligations, Fleming managed to live the life he wanted. As the years passed, his passion for golfing increased so he took more time with it. Fleming's long-term fascination with America grew, so he traveled there more often.

    Ian Fleming's full life caught up with him through his heart. It may be that years of drinking and smoking took their toll, or that the butter-rich cooking Fleming loved was the culprit. Or maybe it was just genetics. Whatever the cause, Fleming's health declined in the late 1950s. This plus anxieties in the marriage increased Fleming's depression. With the success of Bond, the world came knocking at Fleming's door, and he had a harder time shutting those out that he did not want in his life.

    Nonetheless, Fleming fought the loosing battle of his weakening heart by throwing more fuel on the fire. He continued to drink and smoke, making some excuses but not many. He wrote books he wanted to read, and traveled the world with style and authority. By this time, Fleming had already earned his own fortune, created his own identity, and ruled his own literary empire.
