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.

    Several months ago, I attended the opening event for a new children's literacy (读写能力) campaign at the Burbank Library in California. The campaign is called Marvel Comics Close- Up, aimed at using comic books to encourage kids to read. Disney and Marvel donated 210,000 books to libraries and schools across the country.

    Stars from Disney XD participated. They read Spider-Man comic books to 70 kids from Boys & Girls Clubs in southern California. The stars included Drake Bell (Ultimate Spider-Man), Dylan Riley Snyder (Kickin' it), Olivia Holt (Kickin' It) and Coie Jenson (Crash & Bernstein).

    Drake Bell said that the Marvel reading campaign is aimed at kids who are bored with books, believing comic books are the answer for kids who say they'd rather play video games. “Comic books really get you into the story,” he told TFK(Time For Kids). “They are not just words or pictures on a page.”

    Dylan Riley Snyder knows from his experiences that comic books have the power to inspire kids' imagination. His mom was a teacher and she used comic books to interest students who thought they weren't interested in reading. Dylan attended these classes. He would read the comic books and draw the characters along with the students. “It was a great way for these kids to start to enjoy reading,” Dylan said. “That's how I got interested in reading too. Now I can share my love for comic books with others through the Marvel Comics Close-Up program.”

    David Levine is the Vice President of Disney XD Worldwide. He said great stories and great characters, like Spider-Man and The Avengers, were key to making reading fun. “Reading can encourage you to explore new things and take you to all sorts of exciting places,” he told TFK.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic（神经质的）than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    On a recent trip to the island of Newfoundland, Canada, my husband asked our talkative cab driver what made him most proud to be a native.

    "Our generosity and hospitality (好客)" he replied in a strong local accent. "If your car breaks down in the middle of nowhere, someone will stop to help. People here are kind like that." His answer rang in my mind during that ride with my husband and teenage kids, as we headed out to explore on the first day of our vacation.

    Little did I know we were about to experience some of that remarkable Newfoundland kindness for ourselves. We met Alma that same morning at the start of a long hike. Our teenagers hurried ahead, and as we walked behind, admiring the scenery, two women in sunglasses and summer hiking equipment stopped. They'd heard us discussing different routes, and then asked if we'd like suggestions. They looked to be in their 40s, and were both enthusiastic to share their local expertise.

    We listened eagerly, taking mental notes, until one of the women asked, "You have a car, right?" I explained that there were no cars available during our week on the island, so we had to rely on cabs instead.

    "Oh no," she said, "you need a car." And then, as casually as if offering a piece of chewing gum (口香糖), she said, "Take mine!" My husband and I just smiled in disbelief, dumbfounded.

    "Why not?" she insisted. "You need a car to get to know all these places."

    "But you don't even know us," I said.

    "That doesn't matter," she continued with absolute determination.

    Surprised, I looked over at her friend, who shrugged and said, "That's Alma."

    Forty minutes of talking later, my family climbed into Alma's car. We spent the rest of our vacation discovering different areas of this beautiful island. But it wasn't the groups of whales we saw, or the vast areas of woodland, that made this place so memorable. Instead, it was the act of kindness from a complete stranger that made us realize how special Newfoundland really was.

    Next year, there's no doubt where we'll be taking our summer vacation. Who knows what act of kindness we'll meet then?

    Some insects, such as butterflies and ladybugs, are quite beautiful. But, did you know that many bugs are also edible and are filled with protein?

    Aletheia Price knows this—and a lot more—about bugs. She also thinks you should try eating some. If you visit the website www.eatbug.com, you will find all kinds of information about edible insects. Most of it was written by Aletheia Price when she was fifteen years old. Aletheia started eating bugs at the age of thirteen. Before long, she found that she really enjoyed some of them. She also became interested in finding out more about which kinds of bugs could be eaten and how to cook them.

    According to Aletheia, there are at least 1,462 kinds of edible insects. (Doesn't that make you wonder who tried all of them and decided they were edible?) Some of her favorite dishes include mealworm chocolate chip cookies, ant tacos(玉米卷), and chocolate-covered crickets(蟋蟀). On her website she has recipes for insect entrees(开胃菜) and some helpful tips. For example, when preparing crickets, it is best to remove their legs before cooking, for the legs tend to get stuck in your teeth. She also offers information for anyone who wants to raise bugs for food.

    Aletheia realizes that eating bugs is not for everyone. But, if you think about it, you have to admit that eating bugs might be a good idea. There are billions and billions of bugs in this world. If we could get used to eating them, we would have plenty of food for everyone.

Tips for Writing Short Stories

    I was reading an article with David Vann's top tips for writing short stories -- he is a published writer, his most famous book being, "Legends of a Suicide." First of all he stats that there are no rules, but if he were forced to create rules for short stores, then they would be something like the following.

    He says there is no room for anything that is not related to the protagonist -- the main character of the story -- or indeed the problem of the protagonist. He makes it clear that the protagonist must have a problem, and this problem must divide the protagonist: he doesn't know what he is going to do to solve the problem. There is no point, then, in having a short story about a man who says he is hungry and then just goes to the shops to buy food. Nothing exciting happens. But if the man is hungry and he has a child who is hungry, then he has a problem; who does he give the food to?

    There should also be an antagonist, that is, somebody who works against the protagonist. The antagonist should ideally have the same problem as the protagonist but will have a totally different way of looking at it. This presents the possibility of having battles in the short story.

    Furthermore, the antagonist and the protagonist must know each other. But because they are viewing the same problem from different angles, they will probably drive each other crazy.

    Finally, the short story has to acknowledge a change in the protagonist. We must then, as a reader, see how the character will continue their life differently as a result of the events of the story. There is no point in going back to the beginning; the short story is a waste of time if nothing actually happens that is significant.

    It is very hard to create a character whom a reader cares about and a plot that a reader is interested in with just a few hundred words. But it is possible: Edgar Allen Poe, Anton Chekhov, and JG Ballard -- amongst many others -- have proved repeatedly that short stores can be little pieces of perfection. The best don't just see the protagonist change; they see the reader change, too.
