| Now we have comfortable buses in New York. I would like to tell to you how comfortable they are. The number of the seats on a bus is from 44 to 19. At first, they just changed the normal (正常的) seats to airplane seats and took off 10 seats on the bus. However, everyone wanted to have a more comfortable seat on the bus when they took long trips by bus. Also, the bus manager (经理) wanted to get more money, so they changed the airplane seats to sofas, and the number of the seats becomes 19. The new buses are coming out, but the prices are going up too. The owners have many ideas Maybe you never think about these before. Now they have bus waiters, they serve (提供) water, snacks, newspapers and toys. Also, you can change the direction of the sofas so that you can feel more comfortable, and they have a service (服务) bell on each sofa. Some managers even ask bus drivers to play some videos on the bus. When you take a long trip, they provide luxurious (豪华) buses that have an LCD(液晶 彩色显示器)on each seat. That is not the only surprising thing on the bus--they also have three different video channels(频道), and seventy TV games for killing time when you are on the bus. In a word, we want to be more comfortable when we are on a trip. That is the reason why we have sofas on the buses. Maybe we will have beds on the buses in the future. | ||||||||
