阅读理解。 Until I started my Happiness Project, I didn't think much about rituals and whether they made me happy. But when I reflected on them, I realized that I found rituals both calming and energizing. For example, in my high school, exams were taken very seriously. When everyone was steeled at a desk, the teacher would pass out the papers, and we would lay them face down. She would return to the front of the classroom, look at the clock, and say quietly, 'It is 9:10 now. You have two hours. Be sure to read all the instructions carefully'-then a pause -'you may turn over your test paper and begin now.'  This familiar, quiet formula made the start of an exam into a little ritual that put me in the right frame of mind to face a tense exam. In kindergarten, after singing a good-bye song, the children stand in a circle in the classroom, while the grown-ups wait in a line outside the door. The teacher calls the children's names, one by one, and the child comes to the door to get a big hug and to leave. The orderliness of this process keeps everyone calm and cheerful. So think about rituals in your life. Take a moment to taste the enjoyable ones. Think about opportunities to heighten the experience of an ordinary occasion by treating it with special consideration. This is particularly useful if it's a stressful or emotional experience, discussing a child's report card, giving a performance review. Packing for a trip, or getting ready for a date. Studies show that family traditions and family rituals encourage children's social development and improve feeling of family. They're not just important for children but for the whole society. 1.
