When you visit America, you will see the word Motel on signs and notice boards. It is made up of “motor” and “hotel” and it is really a hotel for people who arrive by car (however, you don’t need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria (自助餐馆). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.

In these great National Parks, you may meet guests you don’t expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow. As she got close, she saw the thief. She was dreadfully frightened: it wasn’t a human thief — it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!

There are also, of course, places called “rooming houses”,  where they receive lodgers (房客). You will see such signs as Tourists or Rooms Rent, and you could try one of these. A word of warning — looking for a room in New York during the tourist season is like looking for gold on the moon!

背景资料：2007年8月13日，xx省xx县堤溪沱江大桥在施工过程中发生坍塌事故，造成64人死亡、4人重伤、18人轻伤，直接经济损失3974.7万元。直接原因是：堤溪沱江大桥主拱圈砌筑材料不满足规范和设计要求，拱桥上部构造施工工序不合理，主拱圈砌筑质量差，降低了拱圈砌体的整体性和强度，随着拱上施工荷载的不断增加，造成1号孔主拱圈靠近0号桥台一侧拱脚区段砲体强度达到破坏极限而崩塌，受连拱效应影响最终导致整座桥坍塌。间接原因是：（1）建设单位严重违反建设工程管理的有关规定，项目管理混乱。（2）施工单位严重违反有关桥梁建设的法律法规及技术标准，施工质量控制不力，现场管理混乱。（3）监理单位违反了有关规定，未能依法履行工程监理职责。（4）承担设计和勘察任务的设计院工作不到位。（5）有关主管部门和监管部门对该工程的质量监管严重失职、指导不力。（6）州、县两级政府和有关部门及省有关部门对工程建设立项审批、招投标、质量和安全生产等方面的工作监管不力，对下属单位要求不严，管理不到位。

这是一起生产安全责任事故。（）
