高铁地上的地标怎么看？
在高铁/动车停靠的站台上，地面会有不同颜色标记，共橘黄色、绿色、蓝色和紫色4种颜色，上面写有车厢号和其他车厢方向箭头。其实，这就是所谓的“地标”，用来方便乘客候车，高铁进站停车后，车厢门一般恰好与地标上的车厢门一致。
为什么非要设立4种颜色的地标呢？原来，每条铁轨上有数辆高铁行驶，一个站台经常会接收和发送不同方向的列车，不同方向的列车自然会有不同的排序。同时，不同列车长度还不同，比如有的8节、有的16节。因此平台上的“地标”位置也发生了变化。

请到我的家乡来，这里的景色可美了 ！一副天然的农村景象，一来就会让你留恋往返的哦！如果你来的是秋天，那就更好了！你也许会问：“为什么好呢？”你就耐心地听我讲解吧！ 秋姑娘越过田野，使田里的稻谷变得金黄金黄的，田里的青蛙好像非常高兴，老在田里跳来跳去的，请到我的家乡来作文。稻谷好像被风吹得直弯腰，农民有的驾驶着收割机收割着稻谷，有的农民用镰刀割着稻谷。农民的脸上挂着温馨的笑容。小孩子也开心地在田里打滚，整个田里发出会心的笑容。 秋姑娘飞跃小河边，使小河边的大树的叶子变成了黄色，树上果实累累，使人立刻想摘下来尝一尝果实的味道
《爵士乐》这本书大体讲什么
Jazz is the story of a triangle of passion jealousy, murder and redemption, of sex and spirituality, of slavery and liberation, of country and city, of being male and female, African American, and above all of being human. In the story, Joe Trace is in his fifties. He is a door-to-door salesman who migrated from town to the city with his devoted wife Violet. He meets Dorcas, an eighteen-year-old girl, and he falls in love with her. The relationship doesn’t end well, as Joe shoots her to death at a party. During the funeral, his wife Violent tries to disfigure the corpse of her rival with a knife. In the novel Jazz, Toni Morrison described a black family move from town to the city, which is what happened on his father. Both of her parents came from sharecropping families who had moved North in pursuit of better living conditions in the early 1900s, and her father’s family had faced a great deal of discrimination.
