陪同外方人士在路上行进时要注意哪些礼仪？
参考答案：
陪同外方人士在路上行进时，在礼仪上的位次排列可分做两种：一是并排行进。它讲究“以右为上”，或“居中为上”。由此可见，陪同人员应当主动在并排行走时走在外侧或两侧，陪同对象走在内侧或中央。二是单行行进。它讲究“居前为上”，即请陪同对象行进在前。但若陪同对象不认识道路，或道路状态不佳，则由陪同人员在左前方引导。引导者在引路时应侧身面向被引导者，在必要时提醒对方“脚下留神”。

In some places, people use a bicycle to get to work. In other places, bicycle riding is a very popular exercise to people who live in cities. But who invented the first bicycle? In 1791, a Frenchman named Comte de Siverac invented and owned the first bicycle. Mrs. Sivrac rode the bicycle in Paris. The handles(把手) and the seat were wooden. This bicycle was very difficult to move. A rider even had to pick up the front wheel to change direction. Finally, the bicycle had no brakes for stopping or pedals for the feet! Riding a bicycle was a great risk! In 1817, a German named Baron von Draus de Sauerbrun made the first bicycle better. The seat became more comfortable. The wheel could now change direction. His ride in the forest took only one hour instead of three hours on foot, which surprised people at that time. Sauerbrun brought this kind of bicycle from Germany to France. Then Denis Johnson, an Englishman, made a bicycle for women. It had spaces for their dresses to hang down. But these bicycles still had no brakes or pedals, and riders often got hurt. These bicycles and the people who rode them were not very popular. It took another forty-five years for the bicycle to become popular. More than 100 years later, bicycle riding is more popular than ever. In fact, in India and China, there are still many more bicycles than cars. The Great Invention
