首先明确这几个词的核心用法差异：
1. over作介词，侧重表示在物体的正上方横跨/越过，第一句新桥是修建在河流的上方横跨河面，符合over的使用场景。
2. through作介词，侧重表示从物体的内部空间穿过，阳光是穿透窗户的内部空间照进室内，符合through的使用场景。
3. across作介词，侧重表示从物体的表面横向横跨越过，飞越大西洋是从大西洋的水域表面横跨，符合across的使用场景。
4. cross是实义动词，意为“穿过、越过”，第四句主句用了一般过去时，从句时态保持一致，缺少谓语动词，因此用cross的过去式crossed，表示冲过终点线。
5. past作介词，意为“经过、路过”，walk past是固定搭配，意为“走过/路过某地”，符合路过村庄的语境。
