Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”

    Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real talk I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

    Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk,burningto find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?

    Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster's office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

    We could say that any animal that knows how to find food, avoid being eaten, and raise babies is pretty smart. But can animals learn and remember or can they solve problems?

Many animals have good memories for where food is — a useful skim Scrub jays (灌丛鸦) may be the champions. In one experiment, scientists put them in pre-made holes. After the jays had hidden some food, they were taken out. Scientists mapped where the food was hidd6n and then remove ii, which meant the jays couldn't find the holes by smell. But when the jays came back again, they went right to the hiding they had used. In the wild, they remember where thousands of holes arc. Could you do that?

    Another important smart skill is being able to spot shapes and generalize. This kind of test work best with animals that see well and are interested in pictures. Call in the pigeons(鸽子)! In this test, pigeons had to learn to pick out photos with trees in them, and to ignore photos that didn't include any trees. Once they had learned the rules, they were very adept at it.

    Scientists have to be careful when they test animals for smarts, and the person giving the test has to know the animal really well, in one experiment, a few bananas were hung out of reach over a p on the ground. Monkeys figured out right away how to get the bananas: pick up a stick and knocked down. But clever elephants kept failing this test. Finally scientists figure out why. An elephant's trunk work as both its hand and its nose. When it got the stick, it couldn't smell the bananas. When the elephants were given a couple of boxes instead, they quickly use them to make a step and got the bananas.

    As we're learning, the world is full of smart animals, each thinking in its own special way.

    Simone was born in Ohio, but grew up in Texas. Early on, she and her siblings (兄妹) were adopted by her grandparents, who she says support her in everything. She first realized she wanted to be a gymnast at the age of 6 when she and her classmates went on a field trip to a local gym. A coach at the gym saw her natural talent and wrote a letter to her grandparents urging them to get her involved. The sport she signed up for “for fun” soon turned into her life's enthusiasm.

    Simone is energetic, so it's no surprise that she's got a few medals in her time. Her ten world gold medals are the most ever achieved by a woman in gymnastics history. She is also the first woman to win four medals at the same World Championships, which happened in her second year performing in 2014.

In 2015 Simone became the first gymnast to win three constant all-around titles at the World Gymnastic Championships. She even amazed herself, telling the interviewer “I blew my own mind.” and posting to social media “breaking history is kind of cool.”

    What surprised everyone most though, was that she was performing perfectly as she usually does—her skill is so beyond everyone else that she can't be beaten even when she trips up!

    At schools across the United States, students often sit down to cafeteria lunches made from processed foods that are high in fat, sodium, and sugar. But kids at Public School(P. S. )216 in Brooklyn have a different dining experience. Principal Donna Neglia reports that her students love eating fresh fruits and vegetables.

    P. S. 216 participated in the Edible Schoolyard Project, a nonprofit program founded by Chef Alice Waters in 1995. The program that Waters created helps public schools across the country start on-site gardens and weave principles of healthy eating into the curriculum. Students grow and maintain crops, harvesting the fruits and vegetables for cafeteria meals.

    Waters expressed her passion for the principles of the farm-to-table movement. She advised schools to connect with the farmers in their area and change their buying practices when planning meals for students.

    Waters has long been inspiring people to care about where their food comes from. In 1993, she put forward the idea of a White House vegetable garden. It was not until 2009 that Michelle Obama started the garden in the backyard of the White House. She and members of the kitchen staff spent hours tending to the garden, often with help from local school children.

    “That gave people a sense that she cared about children and cared about where our food comes from,” Waters said, praising the former First Lady's concern for young people's health. “We are just building this movement, and it is very exciting. ”

    “Through the Edible Schoolyard Project, students also learn about the benefits of healthy eating in the classroom.” Neglia said. “P. S. 216 is teaching kids about careers in the food industry—such as farming and agriculture, nutrition, food safety, and the restaurant business.”

    Similar classes are taking place around the country. So far, the Edible Schoolyard Project has reached more than 1 million students in more than 367 schools. “I'm thinking about the future of the planet,” Waters said. “I'm doing this for our generation.”

    When the weather is good, most children would like to play outside. So we asked some kids and their parents whether the following toys kept them happy.

    All Surface Swingball, $35.99

    Played by Martin, nine, and five-year-old Alex in Crewe, Cheshire.

    Mother Jennifer says, "The boys thought the toy was excellent and really wanted to play with it. It can be played with alone or with another child. It's for the right age range but I believe the toy can be played with by all ages and is suitable for the whole family."

    Rubberwood Quoits Set, $13.99

    Played by Jessica, four.

    Mother Lucy Hayburst, 37, in Chichester, West Sussex, says, "Jessica played with this toy for a few minutes but quickly stopped playing with it. Since we bought this toy for her, she only played several times. The quality is very good. It can be played with by one child or more. Besides, I believe it's more suitable for older kids."

    Wooden Animal Skittles, $14.99

    Played by Matthew, two.

    Father Richard Lee, 36, from Dartford, Kent, says, "Matthew was very interested in the toys and liked to play with them, but that only lasted for around five minutes. The skittles were fun at first but that feeling soon disappeared. Two or more children can play with the toy together. And I think they are most suitable for kids aged between three and seven. Our youngest son, Ethan, just kept trying to eat the lion's head."

    First Tailball Net Set, $22

    Played by James, five.

    Mother Sarah Schwar, 39, from Grays, Essex, says, "James loved the toy." He enjoyed balls so it was perfect for him. We used it in the summer as it was easy to take on trips. It is suitable for kids over five years old. I think the price is fair and your children deserve it."

Daphne Soares, a biologist, makes an amazing discovery about alligators. The first time she got really close to an alligator (短吻鳄) was when she was helping to bold down an eight-foot American alligator. It was then that she noticed is face was covered with little black spots. This led to the discovery of the little black dots.

She started her study of the black dots. When she read the books and scientific journals, she learned that people had noticed the dots, but no one really knew what the dots were for.

To find out the secret she placed electrodes (电极) on nerves coming from some of the dots. When the nerves fired, they sent a message to the brain and created a tiny electric current. Just then she heard a small sound over a loudspeaker. She tired to see if the dots acted like eyes and temperature sensors, but nothing worked.

One day she was careless with dropping a tool into an alligator's tank. When she put her hand in the tank to get the tool out, she made small waves in the water. When they reached the alligator's face, she heard a noise over the speaker. She then realized that the dots must be sensitive to the changes in pressure when hit by waves of water.

After that, she is now studying blind cavefish. She is trying to learn whether they are blind from birth or lose their sight as they grow up. She is also doing more research on crocodilians (鳄目). She wants to find out how the genes of alligators with pressure sensors only on their faces differ from the genes of crocodilians that have pressure sensors all over their body.
