It was the first time I had been abroad. It was also the first time I had taken a trip by myself. I had great enthusiasm and high hopes, and I wasn39。t let down. It39。s hard to describe how I felt when I arrived at the airport in New York. Looking at people of different races and nationalities passing by and hearing different languages all around me, I couldn39。t say anything for a long time. I had never understood the cultural diversity of the US so clearly and closely before. The following days were even more impressive. We integrated(融入)into the forest of concrete and cement(混凝土和水泥). We waved to the Statue of Liberty。 we looked down at the busy island of Manhattan。 we looked at wellknown universities—Harvard of ancient Egypt. Then we visited some wellknown university—Harvard, Yale, Princeton and Columbia—each with its own appealing and timehonored history. But what all these universities have in mon is their peaceful academic atmospheres witch you could feel everywhere. I was impressed by the libraries, decorated just like cathedrals(教堂), and the laboratories just next to the classroom. My dream is to return to those places as an international student. Finally came our destinations—the Model United Nations conference at the University of Chicago. Students from various countries arrived to act as United Nations delegations and share their opinions about global issues. As a nonnative speaker, I felt that peting against native speakers was a very tough task. But it was also a rare change to improve my English and I couldn39。t throw it away. With perseverance and devotion. I got used to talking to other delegations naturally. Although I didn39。t win any awards, the chairman praised me at the closing ceremony for my excellent performance. That made me feel really proud. This trip brought me unforgettable and valuable experiences that will benefit me forever. （1）What is the main purpose of the author39。s going to America?

His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier. These are the findings of a 40173。year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. Boys who worked in the home or munity gained petence (能力) and came to feel they were worthwhile members of society, said George Vaillant, the psychologist (心理學(xué)家) who made the discovery. And because they felt good about themselves, others felt good about them. Vaillant39。s study followed these males in great detail. Interviews were repeated at a
