Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character,and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

        Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

        To answer these questions, Brooks surveys a wide range of disciplines（学科）. Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention.So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science.

    Henry Ford was born on a farm on July 30th, 1863. The farm was near the city of Detroit.

    Henry was always interested in machines. He enjoyed fixing clocks.And he helped repair farm equipment. When Henry was sixteen years old, he left the family farm and went to Detroit to learn more about machines. Henry used what he learned from work to develop engines. In 1903, he was ready to start building cars for the public. On July 15th, 1903, a man named Doctor Pfenning bought the first car from the Ford Motor Company.

    The sale to Doctor Pfenning was the beginning of a huge number of requests for Ford cars.By the end of March, 1904, almost 600 Ford cars had been sold. At the start of 1905, the Ford Motor Company was producing 25 cars each day.

    Henry Ford was sure the future of the automobile industry was in a low-priced car for the general public. He said then, and many times after,“I want to make a car that anybody can buy.”

    In 1907, Henry Ford said: "I will build a motor car for the great mass of people. 1t will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one.”

    Believe it or not, school uniforms are absolutely not only clothes for students. They stand for the culture or beauty appreciation standard of a country. To wear uniforms has become a trend in most countries in modern society. Well, let's take a look at school uniforms in different nations. This will be interesting. And here, you will detect diverse allure (魅力)！

    The style of England school uniforms is rather classic, simple and respectable. Middle school students must wear traditional western-style school uniforms. Boys wear traditional western-style clothes, regular leather shoes and must wear neckties. Girls also wear western-style clothes, regular leather shoes and must wear bow ties. This classic clothing style unconsciously affects England students' temperament(性格)and also sense of beauty.

    Both boy and girl students in Australia are required to wear black leather shoes and white socks. They wear school uniforms all the time except the physical education, when they need to wear gym suits.

    Students in Malaysia obey rather strict rules. Girls' dresses must be long to cover the knees. Shirts must cover the elbow. Comparing with Thai students, they are much more conservative. School uniforms in most schools of China are only different in size. You can't find big differences between boys' uniforms and girls' uniforms only from the appearance. Both of them are loose sport suits.

    Junxi “Emma” Yang played Carnegie Hall before she got to high school. But her piano skills may have to take a back seat to her programming skill.

    According to World Journal, a US-based Chinese media organization, Emma, a 14-year-old student at the Brearley School in Manhattan, New York started coding when she was 6. Four years later, her beloved grandmother began developing Alzheimer's.

    When Emma's family moved to New York from Hong Kong in 2014, she became passionate about programming. By the time she was 10, her grandmother had already developed the disease.

    Emma got right to work. With her coding skills, she had a smartphone app created before long, designed to help people suffering from Alzheimer's.

    “Now, 'Timeless' has moved to the second stage of design,”says Emma.

    Emma hopes her grandmother can benefit from the artificial intelligence technology built into “Timeless,” the app Emma developed, to overcome her memory loss.

    Emma's newly finished app has gained support from Dr. Melissa Kramps, an Alzheimer's specialist, and from Kairo, a developer specializing in artificial intelligence.

    Timeless uses facial recognition to remind someone with Alzheimer's of vital information about the person whose photo they are looking at on their screen. It also signals whether they have just called somebody.

    The app also allows for the photo-talking, then moves to identify the people on the screen.

    The Timeless project is featured on the website Indiegogo for fundraising. Emma is hoping to raise $50,000 and work alongside professional programmers to have Timeless launched by the end of 2018.

    Many people have hailed Emma for her efforts. Bill Gates voiced his support, commending her on her bid to help bridge the gap between people with Alzheimer's and the ones they love.

    After finishing a meal at an American Chinese restaurant you probably expect to receive a handful of fortune cookies after you pay the bill. Fortune cookies are in Chinese restaurants throughout the United States. It's rather satisfying to crack open a cookie at the end of your meal and read your “lucky fortune” on the slip of paper inside.

    The exact origin of the fortune cookie is unknown. It is thought that the tasty snack was the first introduced into San Francisco in 1914, after an immigrant began distributing the cookie with “thank you” notes in them. These “thank you” notes were intended as symbols of appreciation for friends who stood with him through the economic hardship and discrimination of his early life in America.

    There is an alternate origin story. Los Angeles is regarded as the site of the fortune cookie's invention. In this version of the story, David Jung, a Chinese immigrant residing in L. A., is thought to have created the cookie in order to uplift the spirits of the poor and homeless. In 1918, Jung handed out the cookies for free to the poor outside his shop and each cookie contained a strip of paper with an inspirational sentence printed on it.

    Fortune cookies first began to gain popularity in mainstream American culture during WWII. Chinese restaurants would serve them in place of desserts, as desserts were not popular in traditional Chinese cuisine. Today fortune cookies are not tied to Chinese-American culture. In fact, the largest fortune cookie manufacturer is located in the United States and it produces 4.5 million fortune cookies a day —— an evidence to the modern-day popularity of the snack. However, an attempt to introduce the fortune cookie to China in 1992 was a failure, and the cookie was cited for being “too American.”

    So the next time you break open a fortune cookie and read a fortune about the many successes you should expect in your future, remember that the conclusion to your Chinese restaurant meal may not be as Chinese as you think.

We use both words and body language to express our thoughts and opinions in our interactions with other people. We can learn a lot about what people are thinking by watching their body language. Words are important, but the way people stand, hold their arms, and move their hands can also give us information about their feelings.

Just like spoken language, body language varies from culture to culture. The crucial thing is using body language in a way that is appropriate to the culture you are in. For example, making eye contact—looking into someone's eyes—in some countries is a way to display interest. In other countries, by contrast, eye contact is not always approved of. For example, in many Middle Eastern countries, men and women are not socially permitted to make eye contact. In Japan, it may demonstrate respect to look down when talking to an older person.

The gesture for "OK" has different meanings in different cultures. In Japan, someone who witnesses another person employing the gesture might think it means money. In France, a person encountering an identical gesture may interpret it as meaning zero. However, you should avoid making this gesture in Brazil and Germany, as it is not considered polite.

Even the gestures we use for "yes" and "no" differ around the world. In many countries, shaking one's head means "no", and nodding means "yes". By comparison, in Bulgaria and southern Albania, the gestures have the opposite meaning. There are also differences in how we touch each other, how close we stand to someone we are talking to, and how we act when we meet or part. In countries like France and Russia, people may kiss their friends on the cheek when they meet. Elsewhere, people favour shaking hands, bowing from the waist, or nodding the head when they meet someone else.

Some gestures seem to have the same meaning everywhere. Placing your hands together and resting them on the side of your head while closing your eyes means "sleep". A good way of saying "I am full" is moving your hand in circles over your stomach after a meal.

Some body language has many different uses. Perhaps the best example is smiling. A smile can help us get through difficult situations and find friends in a world of strangers. A    smile    can    break    down    barriers. We can use a smile to apologise, to greet someone, to ask for help, or to start a conversation. Experts suggest smiling at yourself in the mirror to make yourself feel happier and stronger. And if we are feeling down or lonely, there is nothing better than seeing the smiling face of a good friend.
