我居住在一个小村庄，我要离开我的村庄去使我的梦想成真.我的村庄和城市间有一座大桥.它大约有800米长，我害怕开车，因此我想要骑我的新自行车去，我骑自行车大约要花费3个小时到达那个城市.当我横过那座桥的时候，我有时会停下骑自行车去看河里的小船.船就像一片片的树叶。
I live in a small village. I want to leave my village to make my dream come true. There is a big bridge between my village and the city. It is about 800 meters long. I'm afraid to drive，so I want to go by my new bike. It takes me about three hours to get to the city by bike. When I cross the bridge，sometimes I stop riding to see the boats in the river. The boats are like leaves.
