It's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends — every moment in their life would be like seeing the world for the first time.

    But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago.

    In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.

    Researchers used computer software to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

    In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively（挑衅地） in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

    Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild.

    “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

    For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

    Sam Allred suffers from a rare and incurable kidney (肾脏) disease. One day, when his sister was playing a song repeatedly, Sam sang along. His sister thought it was funny so she recorded it and posted the video online. The video — and Sam — became a hit. Only 8 years old at the time, he couldn't have expected the response.

    "The Doctors (The television show) called and wanted me on their show so they paid for me to go to California," says Sam, now 13, "and we got to stay in a hotel where all the movie stars stayed."

    During that visit to California, Angie Allred, Sam's mother, had an idea about Sam writing a children's book. Together, she and Sam wrote Opening Hearts, which tells Sam's experience of living with a chronic (慢性的) illness.

    "I wrote the book to teach people to be kinder to people," Sam says. Moreover, Sam wanted to send pillows to sick children staying in hospitals around the country to make their stay more comfortable, an idea that came from a time when he was in the hospital.

    "A few kind boys came in with pillows and they gave me one and it meant a lot to me that someone cared about kids in the hospital," says Sam.

    Angie thought of starting a nonprofit organization to provide a way for people to contribute money to realize Sam's ideas. She named the nonprofit Kindness for Kids.

    Since then, Sam has taken pillows to children staying at Providence Hospital in Anchorage.

    Sam's father, Scott Allred, owns a small business that contracts (承包) shipping services with FedEx Ground. He asked the company for help.

    "FedEx Ground learned about Sam's pillow project," says Erin Truxal, manager of public relations for FedEx Ground. "We thought, 'What a perfect way for us to get involved.' "

    The company provided shipping services for Sam to ship about 5,000 pillows to hospitals.

    Sam wants to send more pillows to all of the children's hospitals in every state. His goal is simple: "Kids in the hospital as happy as they were before they got sick," he says.

    A name is more than just a word. It carries the weight of a person's whole identity. A name can represent a person's ethnicity (种族身份) and culture, or show respect for their ancestral roots. A self-given name may represent a person's beliefs or chosen identity.

    Everyone has the right to have their name pronounced correctly. It is a sign of respect for a person's individuality. "A person's name is to him or her the sweetest and most important sound in any language," Dale Carnegie writes in his book How to Win Friends and Influence People. Behind each name is a story, and when a name is anglicized (英语化), mispronounced, or ignored, that story is dismissed.

    A name mispronounced for a long time can negatively impact a person's attitude toward their own identity. It can create feelings of shame or embarrassment because they are made to feel like a burden. In the long term, this might cause someone to distance themselves from their roots. They may begin shying away from their native language, culture, and family for the sake of fitting in.

    In order to avoid this, many international students living in the U.S. choose English names. People shouldn't have to ignore their identities for the sake of someone else's convenience.

    Everyone makes mistakes, and not everyone can get a name right on the first try. Mispronouncing a name repeatedly, however, shows a lack of effort. It is not okay to be comfortable with mispronouncing names, and being unfamiliar with a language is no excuse.

    If you're unsure whether you're pronouncing a name correctly, just ask. Think of it as a way to expand and strengthen understanding, both personally and culturally. When meeting someone for the first time, make sure that you heard the name correctly. It doesn't take a lot to simply repeat the name back. Spell it out. Write it down. Do whatever you have to do to get the name right. Making the effort to correctly pronounce someone's name is an essential part of cultural competency (文化素养). Without this, we cannot expect to show respect and tolerance for our diverse community.

The summer I turned 16, my father gave me his car — a gift wasted on me at that age. The important thing was that Hannah and I could drive around.

    Hannah was my best friend, a year younger but much taller, almost five foot ten. "Hannah's a knockout," my mother always said. And that summer she signed with a modeling agency. She was already doing runway work.

    A month after my birthday, Hannah and I went to the movies. On the way home, we stopped at the McDonald's drive-through, putting the fries on the seat between us to share. "Let's ride around a while," I said. It was a clear night, full moon slung low over the desert. Taking a turning too fast, I plowed (撞)through a neighbor's wall and drove into a full-grown tree.

    We were taken in separate ambulances. I'd cracked(使裂开)my cheek bone; Hannah's forehead had split wide open. End of her modeling career. What would I say to her?

    When her mother, Sharon, came into my hospital room, I started to cry. She sat beside me and took my hand. "I rear-ended(追尾) my best friend when I was your age, "she said, "I totaled her car and mine."

    "I'm so sorry." I said.

    "You're both alive," she said, "The rest is window dressing. I forgive you. Hannah will too."

Sharon's forgiveness allowed Hannah and me to stay friends throughout high school and college, to be at each other's weddings … The scars are so faded that no one else would notice, but in the sunlight I can still see it just below her hairline — for me, a mark of grace(优雅).

Fishy Weather Conditions

    Laj amanu，Australia，is a dry little town，sitting right on the edge of the Tanami desert. Can you imagines How surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado，only it forms above oceans，lakes，or rivers. Like a tornado，a waterspout moves in a circle at high speeds. When it moves above the water，it tends to carry the fish with it，as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still，the fish in Honduras were very much alive when they rained down to the ground，but they were all blind. In England and Australia，it rained fish and snakes，and none were blind. It was difficult to puzzle out，but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep，underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras，scientists began to connect some dots. Clearly，these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent，and each time，people have tried in various ways to explain this strange phenomenon. Historically，villagers thought the “fishes from the heavens” might be answers to prayers for food. Others suggested that floods overran river banks and oceans，leaving the fish on the city streets. No scientist had actually seen the rain as it occurred，only the fish left on the ground. But in 1990，a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.
