Recently I and other Red Cross volunteers met a group of victims from Hurricane Katrina. We were there, as mental health professionals, to offer “psychological first aid” and I was struck by the simple healing power of presence. As we walked in the gate to the shelter, we were greeted with a burst of gratitude from the first person we met. I felt appreciated, but also guilty, because I hadn't really done anything yet.

    I first realized the power of presence many years ago when a friend's mother passed away unexpectedly. I received a call saying she had just passed away. I wanted to rush down there immediately, but didn't want to intrude(打扰) on this very personal period of sadness. I was torn about what to do. Another friend with me then said, “Just go. Just be there.” I did, and I will never regret it.

    Since then, I have not hesitated to be in the presence of others. Once I sat at the bedside of a young man suffering from the pain of his AIDS-ralated dying. He was not awake, and obviously unaware of others' presence. However, the atmosphere was by no means solenm. His family, playing guitars and singing, allowed him to be present with them as though he were still fully alive.

    In my life, I am repeatedly struck by the healing power of presence. In it, none of us are truly alone. It not only is something we give to others but also changes me for the better.

    It's said that you don't know a man until you walk a mile in his shoes. And you also don't know what it's like for older people to travel until you accompany one on a trip.

    After flying with my elderly father from Washington, D.C. to L.A. in July, I began to realize that a companion has important tasks that can make a journey easier for older people. I booked nonstop tickets on JetBlue to avoid tiring, confusing connections, and we flew directly into small, manageable Long Beach Airport. Even though my father could walk, I arranged with the airline for wheelchair assistance, which meant we got on board first.

    When I took him back to the airport for his return flight to Washington, I got permission from JetBlue to wait with him at the gate instead of saying goodbye at the security checkpoint. I wished he'd had a first-class seat and access to a comfortable airline club. Better yet, I wish I had flown with him both ways. As I watched the attendant wheel him to the lift that took him from the tarmac（飞机跑道）to the plane, I felt like an anxious mom sending her child to school for the first time.

    Things can go awry on a plane trip. And then there is the horrifying story about Joe and Margie. When they landed at Dallas-Fort Worth International Airport, a wheelchair attendant met them to help with a connection. But somehow Margie, who had Alzheimer's disease, disappeared.

    I didn't need to worry about my father wandering away; at 82, his mind was sharper than mine. But his hearing was poor, so I worried about what would happen if he missed an important announcement. Fortunately, everything went just fine. Careful planning made the trip successful.

    Next time I travel with a senior, I'll know better. I hope there will be a next time.

    The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.

    As far as the Internet being a part of our lives. - Well, that train has left the station. This expression means there is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure (血压) in a young group: teenagers.

    The study results show that teens who spend at least 14 hours a week only may cause high blood pressure, which makes your heart and blood vessels (血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and other diseases.

    The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 t0 17 years old, took part in it. 134 0f the teens were described as "heavy Internet users". And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure.

    The lead researcher is Andrea CassidyBushrow. She said, "Using the Internet is part of our daily life, but it shouldn't ruin us." Ms. Cassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn't let their children use the Internet for more than two hours a day, five days a week.

    People need to relax and enjoy themselves. One way they can have a good time is to watch a baseball game or another sports event. Even thousands of years ago, groups of people gathered to watch skilled athletes (运动员).

    Over 2000 years ago in Greece, certain days in the year were festival days. These were holidays when people stopped work and enjoyed themselves. They liked to watch athletes take part in races and other games of skill.

The most important festival was held every four years at the town of Olympia. It was held in honor of the Greek god Zeus (宙斯). For five days, athletes from all parts of the Greek world took part in the Olympic Games. At the Olympic Games, people could watch them box, run, jump and so on. There was a relay race between two teams of men in which a lighted torch (火矩) was passed from runner to runner. The Olympic Games were thought to be so important that cities which were at war with one another had to stop fighting. People were allowed to travel to the games safely. Thousands of people came to Olympia from cities in Greece and from her colonies (殖民地) in Africa, Asia and Italy. They met as friends to cheer their favorite athletes and to enjoy themselves.

If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

The reason is thought to be the so–called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, "Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start."

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, "This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful."

Half a Day

    I walked alongside my father, holding his right hand. All my clothes were new: the black shoes, the green school uniform, and the red cap. They did not make me happy, however, as this was the day I was to be thrown into school for the first time.

    "Why school?" I asked my father. "What have I done?"

    "I'm not punishing you," he said, laughing. "School's not a punishment. It's a place that makes useful men out of boys. Don't you want to be useful like your brothers?"

    I was not convinced. I did not believe there was really any good to be had in tearing me away from my home and throwing me into the huge, high-walled building.

    When we arrived at the gate we could see the courtyard, vast and full of boys and girls. "Go in by you," said my father, "and join them. Put a smile on your face and be a good example to others."

    I hesitated and squeezed his hand firmly, but he gently pushed me from him. "Be a man", he said. "Today you truly begin life. You will find me waiting for you when it's time to leave."

    I took a few steps. Then the faces of the boys and girls came into view. I did not know a single one of them, and none of them knew me. I felt I was a stranger who had lost his way. But then some boys began to glance at me in curiosity, and one of them came over and asked, "Who brought you?"

    "My father," I whispered.

    "My father's dead," he said simply.

    I did not know what to say. The gate was now closed. Some of the children burst into tears. The bell rang. A lady came along and said, "This is your new home. There are mothers and fathers here, too. Everything that is enjoyable and beneficial is here. So dry your tears and face life joyfully."

    Well, it seemed that my misgivings had had no basis. From the first moments I made many friends. I had never imagined school would have this rich variety of experiences.
