Food serves as a form of communication in two fundamental ways. Sharing bread or other foods is a common human tradition that can promote unity and trust. Food can also have a specific meaning, and play a significant role in a family or culture's celebrations or traditions. The foods we eat—and when and how we eat them—are often unique to a particular culture or may even differ between rural (农村的) and urban areas within one country.

    Sharing bread, whether during a special occasion (时刻) or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition hits its roots in the custom of sharing bread.

    Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread represent blocks of gold for prosperity (兴旺) in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies (预示) success in the New Year for the person who receives it.

    Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity.

    Nutrition is necessary for life, so it is not surprising that food is such an important part of different cultures around the world.

    A middle-aged man with a long beard was caught by the police for bad behavior and property damage. The man, Bill Wild, checked into a hotel last night, telling the clerk he would pay cash in advance and would be staying for four nights. He then asked her where the nearest store was and she told him it was John-Johns.

    Wild went to the store and bought three gallons of honey and four gallons of chocolate syrup (糖浆). The cashier asked him why he wanted these things and he replied, "I'm trying to become a sweeter person." The cashier smiled at the joke. Wild drove back to the hotel. He opened all bottles and poured them into the bathtub. He added warm water to the mix. He tuned the radio to an opera music station, took off his clothes, jumped into the tub, and started singing loudly with the music.

    Fifteen minutes later, the neighbor phoned the clerk complaining about the noise. The clerk knocked on Wild's door, but he just kept singing. She phoned his room, but he didn't answer. Then she called the police, who arrived quickly. They broke into the room. The floor was covered in water and the bathtub was full of chocolate and honey. "He seemed so nice and friendly. Who'd have thought he was a bathtub-singing nut?" said the clerk. The police said this was the third time that Wild had been arrested for this kind of behavior.

    Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels(板). However, instead of turning sunlight into energy as solar panels do, the material turns heat into infrared（红外线的）radiation.

    Shanhui Fan is an electrical engineering professor at Stanford University. He says that the panels have a layer of material that is like sand. The panels act like a mirror. They take heat out of buildings and reflect the light from the sun. And he says both the heat and sunlight arc sent 100 kilometers into outer space. "It's a structure that cools itself without electricity input, even under the sun. So, what it does is basically radiate heat to outer space and also reflect the sunlight so it doesn't get heated up by the sun. Mr. Fan says it is like having a window into space. The heat is sent directly into space without increasing the air temperature

    He says buildings in developing countries that do not have electricity or air conditioning could use the panels. "In areas where electricity is out of reach for many people, there is a potential benefit for storing medicine or even food. In many of these situations, being able to reduce the temperature is important. And this would provide a way to do it.”

    The researchers say the main problem is creating actual cooling systems using the high-tech panels. They say it may be possible to develop a cooling spray(喷涂）that could be used on present solid structures. They believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems.

    Tears ran down from my eyes as I saw the essay my high school English teacher had just handed back. A big F was written on top. I was hopeless. I was stupid !My face burned with shame when my classmates called me stupid.

    “I'm the only one who doesn't know my ABCs!” I sobbed to Mom.

    “I'll help,” she promised.

    Everyday I sat with her, but to me, cat looked like cta and red was reb. Frustrated, I would return to my bedroom and draw, filling the paper with houses, restaurants and offices.

    “When I grow up, I want my own store,” I told Mom , pointing to my drawings.

    “That's great!” she said, “ but first you have to learn to read.”

Later, I was diagnosed with dyslexia (失读症). So Mom took me to a learning centre, where I was given reading exercises. But I still had a hard time. Finally, I graduated, but I was afraid of my reading skills.

    “I'll never get a job !”  I cried to Mom later again.

    “Don't focus on what you can't do,” she comforted, “ Concentrate on what you really can.”

    But what can I do? I wondered. Suddenly, I thought of the drawings I'd made as a child and my dream of having my own store. I enjoyed sales so much that over the next few years, I tried my hand at other businesses. Today, I watch over seven branches. We have 187 employees and $15 million in sales.

    While I'll never be what my teachers might have wanted, I am a success--on my own terms. The other day a student sent me a card, reading: You gave me so much confidence. I hope to be like you when I am big. Tears of joy filled my eyes. This was my A, and I smiled.

    If Confucius (孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. We'd need a fan or a strong wind to help him put them out. While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

    But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually included Chinese art, history and philosophy (哲学). Some social scientists suggest that Westerners should take advantages of the ancient Chinese wisdom to make up for the drawbacks of Westerners philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

    So the old thinker's ideas are still alive and well.  Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West. As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow (乌鸦) landed on their window.

    The father asked his son, "What is that?"

    The son replied, "That is a crow."

    After a few minutes, the father asked his son for the second time, "What is this?"

    The son said, "Father, I told you just now. It's a crow."

    After a little while, the father asked his son the same question for the third time, "What is this?"

    This time, the son said to his father in a low and cold tone, "It's a crow, a crow."

    After a moment, the father yet again asked his son for the fourth time, "What is this?"

    This time his son shouted at his father, "Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW'. Are you not able to understand this?"

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page.

    Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feel angry, but instead felt affection for my son.

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. From today say this aloud, "I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the best way no matter how they behave."
