    Susan Cain: The power of Introverts (性格内向者)

    Does a cup of tea and a good book sound like a perfect Friday night? In this personal talk, Susan Cain argues that introverts have important talents and abilities. Our culture may value being social and outgoing, but the world needs all kinds.

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. "There can be no doubt that our trusty bicycles have changed the way people get around our great city," Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, "Bike riding can improve people's happiness."

    Children's books are everywhere. New ones, old ones, made-into-movie ones. It seems as if the children's publishing industry is developing rapidly. Here are some books every young child should have in their book diet.

    The Peter Rabbit books by Beatrix Potter

    It's best to have a copy of the original stories, with the original drawings done by Beatrix Potter herself. In The Tale of Peter Rabbit are the delightful tales of Peter Rabbit. Included in the series are also cute little stories about mice. These books have sweet stories that teach lessons.

The Cat in the Hat by Dr. Seuss

    Dr. Seuss is, of course, the master of children's literature. Dr. Seuss teaches children to play with language and have a good time reading. The pictures are wonderful and inspire lots of fun questions. Big kids will like re-reading Dr. Seuss along with their younger sisters and brothers.

Make Way for Ducklings by Robert McCloskey

    The story of Mr. and Mrs. Mallard is shown by simple pencil drawings that help children use their imaginations. The story explores the city of Boston as the Mallards look for a place to get their ducklings safely across the city. Jack, Kack, Lack, Mack, Nack, Ouack, Pack, and Quack are good examples of obedience(顺从) as they follow Mrs. Mallard through the city.

The Very Hungry Caterpillar(毛虫) and other books by Eric Carle

    The Eric Carle books have delightful pictures, full of bright colors and interesting detail. In The Very Hungry Caterpillar, children see the life cycle of a butterfly through the eyes of a caterpillar that is hungry. The children will laugh at all the food the caterpillar eats and be overjoyed by the beautiful butterfly at the end. All the Eric Carle books are fun for kids and parents, with simple ideas and beautiful art.

    There are many children's books available, and this list is only the beginning. However, these are all essential to a good children's library.

    I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and gone into the adult section of the library to be buried in fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found taught basic techniques, and I tried to practice.

    At first the magic wasn't any good. It was just a trick—a bad trick. I spent hours each day running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks my mom got a carpet and placed it under the mirror to muffle (消音) the sound of the coin falling again and again.

    One day I made the coin disappear on the playground. We had been playing football and were standing in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. Everyone went crazy.

    A few years later, I staged an underwater escape in the river that flowed through the middle of the campus of the University of Iowa, where I went to school. I stood on a boat in the middle of the river wearing nothing but biking shorts. The sky was dead and gray, and the water was cold at the surface, and colder in the depths below.

    Technically, I succeeded. I jumped into the water, sank to the bottom, and escaped from the locks and the chains before swimming to the surface. But it didn't feel like a success.

    In the kitchen of my mother's houses there has always been a wooden stand (木架)with a small notepad(记事本)and a hole for a pencil.

    I'm looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil, five houses later, the current paper and pencil look the same as they always did. Surely it can't be the same pencil. The pad is more modern, but the wooden stand is definitely the original one.

    "I'm just amazed you still have the same stand for holding the pad and pencil after all these year." I say to her, walking back into the living-room with a sheet of paper and the pencil. "You still use a pencil. Can't you afford a pen?"

    My mother replies a little sharply. "It works perfectly well. I've always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in those days."

    Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, "One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back. It turned out to be a real breakthrough for solving the mathematical problem I was working on."

    This story—which happened before I was born—reminds me how extraordinary my mother was, and is, as a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have traveled unaffected through fifty years, rooted in the soil of a cheap wooden breadboard, invisible(看不到的)exhibits at every meal.

    Scientists have connected the "fat gene" with the "happy gene". They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends. The breakthrough could be an explanation for why fat characters, such as The Laughing Policeman and Father Christmas are often described as joyful and kind.

    FTO is the major genetic contributor to being fat. But it is also connected with an eight percent reduction in the risk of depression. Researchers at McMaster University in Canada had been studying whether there was a connection between being fat and being depressed. They found the opposite was true.

    They studied 17, 200 DNA from participants in 21 countries. Results showed people with FTO gene—the fat gene—showed less signs of depression. This finding was supported by three additional international studies.

    Professor David Meyre said, "We set out from the belief that being depressed and being fat both deal with brain activity. We thought that fat genes may be related to depression. However, we have discovered a molecule (分子) contributing to depression. It is the first evidence that an FTO fat gene is connected with protection against depression.

    In a recent interview, actress Lisa Riley said she was more than comfortable with her size. She said she is a "big, really happy" girl who is lucky enough to be confident in her own skin, and added, "Many people want to be thinner. Not me. I love being different and it drives me mad that people don't believe I'm happy with what I am."
