One day, when I was working as a psychologist in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. "This boy has lost his family," he wrote. "He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?" '

I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically.

The first two times we met David didn't say a word. He sat there, only looking up to look at the children’s drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon - in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company. But why did he never look at me?

"Perhaps he simply needs someone to share his pain with," I thought. "Perhaps he senses that I respect his suffering." Some months later, when we were playing chess, he looked up at me suddenly.

"It's your turn," he said.

After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times about his biking with some friends, an d about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one - without any words – can reach out to another person. All it takes is a hug, a shoulder to cry' on, a friendly touch, and an ear that listens.

材料一：被称为“史上最严交规”的俢订版《机动车驾驶证申领和使用规定》与2013年1月1日起施行。新交规中对闯黄灯、故意遮挡号牌等违法行为也加大了处罚力度，而这在车主中引发不少争议。对于“闯黄灯扣6分”的规定，在一项网络调查中，有超过80﹪的网友认为，黄灯亮便罚，不仅易造成追尾，还会大大降低过路口车速，带来更严重的堵塞。但也有近20﹪的网友支持新规，认为“闯黄灯”罚款扣分是一种突破，可以促进养成良好的交通习惯。
