大家在地鐵站的時(shí)候時(shí)常會(huì)聽(tīng)到“左行右立”四個(gè)字。對(duì)于這簡(jiǎn)單的四個(gè)字，你是否做得到呢？如今，扶梯已成為人們?nèi)粘Ｉ�活中不可或缺的設(shè)施，扶梯禮儀也成為了現(xiàn)代都市文明的一面觀察鏡。

Even though you may want to catch your breath and just wait while you're transported up or down, you should still consider others and leave enough space for people in a hurry, so that they can run and catch the train.

　　在包括北京和倫敦在內(nèi)的許多城市中，扶梯上會(huì)貼有“左行右立”的標(biāo)識(shí)來(lái)疏導(dǎo)人流。但一些城市出于安全考慮，禁止人們?cè)诜鎏萆闲凶摺?br />
