Although Paris is often considered the city of romance, close to a million adult who call it home are single. Many single people say that France's capital is one of the most difficult places to meet people. The complaints of this lonely group have inspired a new phenomenon known as “supermarket dating.” At Galerie Lafayette Gourmet, singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes, brown hair, and is 1.8 meters tall, or whatever may be on their romantic shopping list.

    At this Paris location, single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door, they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles.

    With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat.

    Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish（美化）one's appearance or to lie about one's age over the Internet. The supermarket, on the other hand, is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another's grocery basket can say a thing or two about that person's character or intentions. Buying pet food can be a man's way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These days it's possible to find much more than food at a grocery store.

    It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold! Wait a moment. Could it just be a common cold or the flu that's been going around?

    A cold gives you a runny nose and cough. But it's usually easy to deal with. Some take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.

    On the other hand, the flu can be much more dangerous. It usually gives you fever.

    Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.

    Don't worry. If you get a flu vaccine（疫苗）, it can stop you from getting the virus. Flu vaccines work by giving the body a small amount of flu viruses. This causes your body to develop antibodies. So next time you get the flu, the antibodies should help you.

    The flu virus changes every few years. Therefore, there are so many types of flu, such as H1N1 and H5N1. The antibodies for one type of flu can't help us against all types of flu. That's why we need to get vaccine every year.

    However, good health habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen your immune system.

    The arm bones of women who lived 7,000 years ago show a surprising level of strength-even higher than today's professional athletes. that's according to a first-ever study comparing prehistoric(史前的) bones to those of living people. The finding suggests a revision of history- the everyday lives of prehistoric women were filled with hard labor, rather than just sitting at home doing lighter tasks while the men struggled and fought for life.

    Before the study, there are no clear records describing how our ancient ancestors lived. It can be easy to forget that bone is a living tissue, one that responds to the difficulties we put our bodies through, "said lead author Alison Macintosh."Physical force and muscle activity both put pressure on the bone. The bone reacts by changing in shape, thickness and other aspects over time.

    Previous studies only compared female bones to contemporary male bones, the researchers said-and that's a problem, because the response of male bones to stress and change is much bigger than that of women. For instance, as humans moved from a hunter-gatherer lifestyle constantly on the move to a more settled agrarian(农耕的) one, changes can be observed in the structure of the shinbone(胫骨)- and these changes were much more evident in men.

    However, a comparison of the bones of prehistoric women to the bones of living female athletes can help us work out a more accurate picture of what those prehistoric women were doing. "By analyzing the bones of living people and comparing them to the ancient bones, we can start to explain the kinds of labor our ancestors were reforming, Macintosh said. What they found was that women's leg strength hasn't changed a great deal, but their arms used to be very powerful. Prehistoric women, the researchers found, had arm strength 11-16 percent stronger than those of modern rowers, and 30 percent stronger than those of non-athletes.

    When an earthquake hit a small town, many houses fell down. After the earthquake, all the newspapers reported many stories about some of the families who were in trouble.

    One Sunday, when I was reading a newspaper, a special picture touched me. It gave the clothing sizes of each family member. I thought that this would be a good chance to teach my children to help those who were less lucky than themselves. I said to my seven-year-old twins, Brad and Brett, and three-year-old Meghan, "We have so much, and these poor people now have nothing. We'll share what we have with them."

    I filled a box with foods and clothes. While I was doing this, I encouraged the boys to choose their toys and donate some of their less favorite things. Meghan watched quietly as the boys took out their old toys and games and put them together. Then she walked away. A few minutes later she came back with Lucy, her much-loved doll. She put the doll on top of the other toys. "Oh, dear," I said. "You don't have to give Lucy. You love her so much." Meghan said, "Lucy makes me happy, Mommy. Maybe she'll make another little girl happy, too."

    I looked at Meghan for a long moment. She taught me a lesson. It's easy to give something that we don't want any more, but hard to give what we cherish (珍爱), isn't it?

Intelligence is traditionally viewed as the ability to think and learn. Yet in a complex world, there's another set of cognitive (认知的) skills that might matter more: the ability to rethink. Therefore, my aim in this book is to explore how rethinking happens by seeking out the most convincing evidence and some of the world's most skilled rethinkers.

The first section focuses on opening our own minds. You'll find out why a forward-thinking businessman got trapped in the past, how a Nobel Prize-winning scientist welcomes the joy of being wrong, how the world's best forecasters update their views, and how an Oscar-winning filmmaker has productive fights.

The second section examines how we can encourage other people to think again. You'll learn how an international debate champion wins arguments and an African-American musician persuades people to abandon discrimination (歧视). You'll discover how a special kind of listening helped an officer convince the opposing side to join in peace talks. And if you're a Yankees fan, I'm going to see if I can convince you to root for the Red Sox.

The third section is about how we can create communities of lifelong learners. In social life, a lab that specializes in difficult conversations will cast light on how we can communicate better about debated issues like climate change. In schools, you'll find out how educators teach kids to think again by treating classrooms like museums, and approaching projects like rewriting time-honored textbooks. I close by examining the importance of reconsidering our best-laid plans.

This book is an invitation to let go of knowledge and opinions that are no longer serving you well, and to establish your sense of self in flexibility rather than consistency. If you can master the art of rethinking, I believe you'll be better positioned for success at work and happiness in life. Thinking again can help you generate new solutions to old problems and revisit old solutions to new problems. It's a path to learning more from the people around you and living with fewer regrets.
