Two recent studies have found that punishment is not the best way to influence behavior.

    One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.

    They had about two hundred college students play a version of the game known as the Prisoner's Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.

    The other study involved children. It was presented last month in California at a conference on violence and abuse（虐待）. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.

    The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.

    In today's world, English is the most wildly used language. It is our duty to learn English in the new situation of the reform and opening to the outside world. How can we master the English language? I'd like to give you some good advice.

    First, get interested in it. I enjoy listening to foreign friends talking when I was a child. At the same time I watched the English program Follow Me on TV. From then on, I kept on learning English. The more I learned, the more progress I made.

    Second, practice makes perfect. Many people study English very hard, but they are very shy to speak it in public, for they are afraid of making mistakes. Remember you have to make a mistake before you can correct it. A native English speaker makes mistakes sometimes, too.

    Third, the beginners should be encouraged to pay attention to idioms. The English language has many idioms. For example, you should say “ He is as strong as a cow.”

    When I was 16 years old, I made my first visit to the United States. It wasn't the first time I had been abroad. Like most English children I learned French at school and I had often been to France, so I was used to speaking a foreign language to people who didn't understand English. But when I went to America I was really looking forward to having a nice easy holiday without any language problems.

    How wrong I was! The misunderstanding began at the airport. I was looking for a public telephone to give my American friend Danny a ring and tell her that I had arrived. A friendly old man saw me looking like being lost and asked if he could help me.

    “Yes,” I said. “I want to give my friend a ring.”

    “Well, that's nice,” he said. “Are you getting married? But aren't you a bit young?”

    “Who is talking about marriage?” I replied. “I just want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?”

    “Oh!” he said. “There's a phone downstairs.”

    When at last we did meet up, Danny explained the misunderstanding to me.

    “Don't worry,” she said to me. “I had many difficulties at first. There are lots of words which the Americans use differently in meaning from us British. You'll soon get used to all the funny things they say. But most of the time British and American people can understand each other!”

    Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation (感觉) of warmth encourages emotional (情感的) warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist (心理学家) John A. Bargh.

    Psychologists have known that one person's perception (感知) of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable (能干的). Much of this is rooted in very early childhood experiences, Bargh argues, when babies' sense of the world around them is shaped by physical sensations, particularly warmth and coldness.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses (假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly (抽象的),” says Bargh.

    Sweat (汗水)rail its way down my cheek. It was hot, but the air was still and wet. One final play and the State Softball Championship was ours.

    I looked towards people who were watching the game. Sure enough, I found my mom. I always wished my dad were here. The farm needed his full attention, but I did not care.

    Finally, we won! State Champs! I let out a scream of happiness, fall of tears. My mom made a “V” to celebrate my success and smiled. I smiled back at her.

    We all received medals (奖牌), but I cannot remember any of it. I concentrated my thoughts on my dad, I ran to my mom, asking for her cell phone. I had to tell my dad about the happiest day of my life, and complained (抱怨）about how he did not care.

    The phone rang twice, and no one answered. My heart sank with sadness, but I tried again anyway.

    “Hello?” My dad answered.

    “Dad!” I cried. “We won State!” Silence.

    “Dad?” I could hear something on the other end. “Are you crying?”

    “I'm just really happy for you, Meggie,” he said. “And I'm sorry I couldn't be there.”

    An apology（抱歉）was all I needed. I hung up the phone feeling relaxed, and I began to understand how it must feel to be a father. I forgave him for never being there. He worked so I could play. My father loved me enough to let me experience life^ happiest moments without him.

Tea is currently the world's most popular drink, only after water. However, there was a time when tea was known only to the Chinese. So, how did tea originate in China? And how did it get to conquer the world to the extent that people often describe something they really like as their "cup of tea"? 

While we know that tea drink started in China, its true origin remains something unknown. Legend has it that about 5, 000 years ago, Shennong came across tea when dried leaves blew into a pot of boiling water. Following his discovery, tea was used as medicine, included in meals and later offered as a refreshing drink to officials and noblemen. Eventually, it became a common drink enjoyed by all Chinese people. 

The love of tea inspired many people to write about it. Over the years, tea drinking became an important part of China's rich culture. The great poet Du Fu described his tea-drinking experience in poetic language. Lu Yu, a tea master, wrote The Classic of Tea, which remains the earliest and most famous detailed study on tea in the world. 

It is then not surprising that the beauty of tea was eventually spread to a wider world. Tang and Song Dynasties needed strong Tibetan horses, so the Tea Horse Road was born. Porters (脚夫) carrying back-breaking loads of tea bricks made their way through dangerous snow-covered mountain passes, to trade Sichuan and Yunnan tea for horses. Over time, the gift of tea was further delivered to Western Asia and Easten Africa. As early as the Tang Dynasty, Saicho, a Japanese monk came to study in China and took tea seeds and tea-making customs to Japan. Around the 1600s, tea was shipped to Europe from China by Portuguese and Dutch sea traders.
