Recently I paid a visit to Harvard University, where there are top class scientists and professors and the best academic system in the world.
I was pretty shocked when I first stepped onto the campus. Well, it’s not even really a campus. It’s more like a district in a small town.
Harvard’s main buildings are from the 18^th century. They look very old and simple. You might even say they’re a little shabby. They don’t fit the modern idea of university at all. The buildings are surrounded by grass and trees, so I felt as if I had walked into a medieval castle. But when I looked across the street, busy shops and in-fashion students made me feel like I was in the 21^st century again. It creates a strong contrast(对照) and brings a special atmosphere to the school.
Our tour guide Gary took us around and told us, “You see this grass field in the center of the school? Here is where they host their graduation ceremony. They just set up tents and benches and have a very simple ceremony. Unbelievable! Who would think the most talented students just graduate on the lawn?”
I saw some students put a blanket on the grass and lie down to read a book. When I listened to the soft sound of pages turning, along with the chirping(鸟叫声) of the birds, I felt very calm. There was no competitive feeling at all.
Harvard has the world’s first computer in its science center and there are hundreds of high-end computers too. Its religion and the literature departments are also among the best. It is the perfect mix of tradition and new technology. It makes Harvard a very attractive place to study in.
I hope one day I’ll attend my dream school---Harvard.

One day, when I was a freshman in high school, I saw a kid from my class walking home. His name was Kyle. He was carrying all of his books. I thought to myself, “Why would anyone bring home all his books on a Friday? He must really be a nerd(书呆子).” So I shrugged my shoulders and went on. As I was walking, I saw some kids running at him, knocking all his books out of his arms and he landed in the dirt. His glasses went flying, and I saw them land in the grass about ten feet from him. I saw this terrible sadness in his eyes. I jogged over to him, and as he crawled around looking for his glasses, I handed him his glasses. He said, “Thanks!” There Was a big smile on his face. It was one of those smiles that showed real gratitude. I helped him pick up his books, and asked him where he lived, It turned out he lived near me, so I asked him why! had never seen him before. He said he had gone to a private school before coming to this school. I would have never hung out with a private school kid before. We talked all the way home. He turned a pretty cool kid. I asked him if he wanted to play football on Saturday with me and my friends. He said yes. Over the next four years, Kyle and I became best friends.
Graduation day arrived. Kyle was valedictorian of our class, so he had to prepare a speech for graduation. In his speech he said. “Graduation is a time to thank those who helped you make it through those tough years. I am going to tell you a story.” I stared at my friend in disbelief as he told the story of the first day We met. He had planned to kill himself over the weekend. He talked of how he had cleaned out his locker so his Mom wouldn't have to do it later and was carrying his stuff home. He gave me a little smile. “Thankfully, I was saved. My friend saved me from doing the unspeakable.” I heard the gasp go through the crowd as this handsome, popular boy told us all about his weakest moment.
