Hundreds of years ago, a Roman army came north from England to make war on Scotland. The Scots, a brave people, love their country. They fought hard to drive the enemy out of Scotland. But there were too many of the Romans. It looked as if the Romans would win.

    One night, the leader of the Scots marched his soldiers to the top of a hill. “We will rest here tonight, my men,” he said, “Tomorrow we will fight one more battle. We must win, or we will die.”

    They were all very tired. So they ate their supper quickly and fell asleep. There were four guards on duty, but they were very tired, too, and one by one, they fell asleep.

    The Romans were not asleep. Quickly they gathered at the foot of the hill. Slowly they went up the hill. Closer they came to the sleeping Scots. They were almost at the top. A few minutes more the war would be over. Suddenly, one of them put his foot on a thistle (蓟). He cried out and his sudden cry woke the Scots. In a minute they were on their feet and ready for a battle. The fighting was hard, but it did not last long. The Scots wiped out the Romans and saved Scotland.

    The thistle is not a beautiful plant. It has sharp needles all over it. Few people liked it. But the people of Scotland liked it so much that they made it their national flower.

    Being a volunteer brings me happiness. I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick animals can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

    I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2­ to 3­week­old owl. It had already been placed in a carrier for safety.

    I examined the chick(雏鸟) and it seemed fine. If I could find the nest, I might have been able to put it back, but no luck. My next work was to build a nest and settle it in a tree.

    The homeowner was very helpful. A wire basket was found. I put some pine（松树） branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

    Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

    A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had answered to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all—LUNCH！ The parents had done their duty and would probably continue to do so.

Dear Alcohol,

    You've been around forever. I can remember all the pain you've caused for me.

    Do you remember the night you almost took my father's life? I do. He loves you. Sometimes I think he loves you more than he loves me. He's addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn't the only one hurt by you that night.

    Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. "I'm so embarrassed," they said as I held their hair back so that they could vomit (呕吐). "I'm sorry," they said when I called taxies for them, walking them out and paying the driver in advance. "This won't happen again," they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.

    Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was in the midst of it all. She never saw him again. And it's all your fault.

    I wish you'd walk out of my life forever. I don't want anything to do with you. Look at all the pain you've caused. Sure, you've made people happy too from time to time. But the damage you've caused in the lives of millions is inexcusable. Stop luring (引诱) in the people I love. Stop hurting me, please.

Sincerely,

Anonymous

    On the day the tornado hit, there was no indication severe weather was on its way—the sky was blue and the sun had been out. The first alert my husband, Jimmy, 67, and I, 65, got came around 9 p.m., from some scrolling text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the presidential primary debate I had been watching to our local Pensacola, Florida, station.

    No sooner had we found coverage of the tornado than it was on top of us. Suddenly, the bones of the house shook, the power went out, and the wind began to roar through blown-out windows. We had three flights of steps to navigate to the relative safety of the first floor, where a closet fixed underneath a brick staircase might be the firmest place to wait things out. Everything around rattling, we struggled forward, uncertain whether we would make it.

    As we reached the last flight of steps, our front door blew out. Shards of glass flew everywhere. A three-foot-long tree branch whipped, missing us by inches.

    By the time I reached the closet, the tornado had been over us for about a minute. Jimmy pushed me down to the closet floor, but the wind kept him outside. I grasped his arm as the tornado constantly sucked the door open and tried to bring him with it. My knees and scalp were full of glass, but I felt no pain. If I had let go, Jimmy would have flown right out the back of the house and into the bay. Then everything stopped. In those first quiet moments, I couldn't believe it was over.

    The storm lasted four minutes. Four of the twelve town houses in our unit were completely destroyed. Of the houses left standing, ours suffered the most damage. Amazingly, none of us were severely injured.

Discover Nature Schools Programmer

    Becoming Bears (Kindergarten—2 grade)

    By becoming baby bears, children learn from their "parent" to survive the seasons. Kids will find safety in the spring and learn kinds of food bears eat during the summer, and then create a cave for winter hibernation (冬眠). After learning the skills needed to survive, students will go out of the cave as an independent black bear able to care for themselves.(1.5—2 hours)

    Whose Clues? (3—5 grade)

    Kids will discover how plants and animals use their special structures to survive. Through outdoor study of plants and animals, kids will recognise their special structures and learn how they enable species to eat, avoid their enemies and survive. Using what they have learnt, kids will choose one species and tell how they survive in their living places.(3—4 hours)

    Winged Wonders (3—5 grade)

    Birds add colour and sound to our world and play an important ecological (生态的) role. Students will learn the basics of birds, understand the role birds play in food chains and go bird watching using field guides and telescopes. Students will do hands－on activities. Students will use tools to build bird feeders, allowing them to attract birds at home.(3—4 hours)

    Exploring Your Watershed (6—8 grade)

    We all depend on clean water. Examining how our actions shape the waterways around us. Go on a hike to see some of the first－hand challenging water quality problems in a city. Students will test the water quality to determine the health of an ecosystem.

    Each programme is taught for a class with at least 10 students.

    All programmes include plenty of time outdoor. So please prepare proper clothing, sunscreen and insect killers for children.

After a busy morning, lunch can feel like just the pick-me-up you need-but sometimes the meal that you thought would energize you is the very thing that makes you want to nap at your desk.

Feeling tired after lunch, or post-meals in general, is known as postprandial somnolence—or, colloquially, the food coma.

Part of this phenomenon is due to basic physiology (生理学): When humans eat, most of our blood goes to the digestive organs to process the food, said Sandra Arévalo, director of community health and wellness at Montefiore Nyack Hospital in New York state.

The tendency to get tired after eating isn't inherently suggestive of something amiss (出错的). But there can be additional factors that worsen this natural response, making getting through the rest of the workday or any activities feel like a slog. Here's what to watch out for and how to make adjustments.

When it comes to why you feel overly tired after eating, a common cause is consuming meals that are heavy in terms of quantity or quality. Not eating breakfast can lead to overindulging later in the day if excessive (过度的) hunger makes controlling your appetite difficult, Arévalo said.

Sometimes, however, the makeup of certain foods can contribute to tiredness. Fats are the hardest nutrient to digest because their molecules are much larger than those of protein or carbs, said Julie Stefanski, a spokesperson for the Academy of Nutrition and Dietetics. If you had a meal high in fat—such as fried foods or pizza—that could make you feel tired. Meals high in added sugar or refined or highly processed carbohydrates can have the same effect.

The fiber in so-called whole foods like corns slows the absorption of sugar into the body, which means they don't cause blood sugar or insulin spikes and instead give you more stable, lasting energy, said Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic.

"A five-minute walk or something helps to improve circulation and alertness (机敏), as well," Arévalo said.
