This is my first time in Boston, and with excitement and a bit of nervousness, we boarded Boston's duck boat. This duck boat is a combination of car and ship, which shocked me very much. I have never seen such a boat before. On the way, I saw the tallest building in Boston, towering high into the clouds, which made me learn about Boston. We took this boat to the Charles River, which was said to have been very dirty. The government decided to clean it up and make it the cleanest river in the United States, where people can even swim. The duck boat is also very comfortable, you can enjoy the breeze while watching the stunning scenery. This duck boat trip was great.

After finishing the duck boat, we took a ride to the famous Harvard University. We listened to the opening ceremony of Harvard University and the professor told us about his research project: the human ear. I thought there was nothing to study about the ears, but the professor really shocked me. There is a cell called a hear cell in the ear that specifically controls hearing and direction judgment. If you heard a sound that is too loud, the hear cell is damaged, you will not be able to hear or control the direction. After the professor shared the research project, several Harvard college students gave us suggestions for going to Harvard, which I believe will be of great help to us.

After listening to the opening lecture of Harvard University, we began to visit Harvard University. The size of Harvard University exceeded my imagination, and its beautiful scenery also immersed me in it. Harvard University is like a city, with dormitories, office buildings, shops, restaurants, parks, streets, and all kinds of people doing different things: walking, taking photos, and studying. After walking for a while, we arrived at the statue of Harvard President "John Harvard". He sat majestically in a chair, holding his hands on the handles, gazing ahead as if looking at the many students at Harvard. Today's journey has brought me a lot, especially seeing a famous school in the world. I look forward to tomorrow.

我们下午参观了哈佛大学的校园。校园很大，像社区一样，马路和车辆把不同的建筑分割开来。哈佛的美景随处可见，不过最令我印象深刻的还是约翰·哈佛的雕塑。作为世界上最享有盛名的学府之一，起初我对它的印象就是庄重，带着对于知识的尊重，可这座雕像背后的故事颠覆了我对它的认知。雕像刻着一位盛装的男士，下面有着三个词：约翰·哈佛、建立者，1638。这座雕塑是哈佛十分著名的风景，可带领我们参观的学生却说它有3个谎言！我印象中庄严的学府竟然开了这样一个玩笑。登时，我心中与哈佛的距离被拉近了，原来哈佛大学是如此的有趣、开放。短暂思考过后，那位同学告诉了我们。约翰·哈佛曾为哈佛大学提供过资金，所以以他的名字命名，不过他并不是建立者。其次，约翰·哈佛是在1636年捐赠的钱财，而不是1638年。最后，也是最有意思的——那个雕像根本不是约翰·哈佛！原来，在雕刻时，约翰·哈佛的画像已经丢失，雕刻者也不知道他本人的模样，所以雕像并不是哈佛本人。在经历过这样的小故事过后，我已对哈佛大学感到亲切许多，也期待接下来哈佛的课程！

7月5日，我们再一次来到哈佛大学校园，步入自然历史博物馆。

自然？历史？起初我始终找不到这两个词语的联系，而当我迈进窄小的门，踏入这古朴又典雅的建筑时，思绪便顺着交错的楼梯蔓延开来。我随手推开身前的门，霎时间仿佛外面变得异常喧嚣，而我则置身于自然之中，一切都变得那么安静……这里是一个植物的专门展区，沉香色的木柜，昏黄的灯光，好像无时无刻都在让参观者沉静下来。颇让我震惊的是，工作人员说这些无一不是玻璃制作的，却看不出丝毫破绽。也正是得益于材质，植物的每一处细节都被放大，哪怕是花针都能清楚地看出。

接下来，去到了矿石展区。映入眼帘便是各种各样的、五颜六色的矿石，大多都是奇珍异玩，简直应接不暇，以至于使我忘却时间的流逝。抓住尾巴，我便又跑到了动物展区。我穿过一条昏暗走廊，豁然开朗，好似进入陶渊明笔下的世外桃源。这里都是巨型的古生物化石，还有些泡在福尔马林里标本，单是入口就架着一个直径大约两米的龟壳，好不壮观。

闹钟开始作响，望着最后一个展区的入口，而我不得不回头。虽然旅程告一段落，但思考可以持续推进。
