　　该图表从三个不同方面展示了六个城市地铁系统的特点。

　　The table demonstrates the features of the underground railway systems in 6 cities in three different aspects.

　　首先，这六个城市的地铁系统是按年代顺序开通的，其中伦敦是最早的(1863年)，而洛杉矶是最晚的(2001年)。地铁系统在20世纪进入全盛时期，四条地铁线路分别在巴黎(1900年)，东京(1927年)，华盛顿(1976年)，以及洛杉矶(1981年)建立起来。

　　First, the subway systems in the six cities were opened in time sequence with London being the earliest (in 1863) and Los Angeles the latest ( in 2001 ). The underground railway system had their prime time in the 20th century, which saw the construction of 4 underground railway systems respectively in Paris (1900), in Tokyo (1927), in Washington DC (1976), and in Los Angeles (1981).

　　第二，依照从伦敦到洛杉叽的排列顺序，也是根据建造地铁的年代顺序，这六个城市地铁线路长度基本上依次大幅降低。伦敦线路最长，394公里，巴黎第二，199公里，东京第三，155公里，华盛顿126公里。京都和洛杉叽最有趣，分别只有区区11公里和28公里，难与前四名相提并论。

　　Second, seen from London to Los Angeles, which happened to be in chronological order of subway construction, the above-mentioned six cities roughly revealed a trend of sharp decrease in the length of the subway route. London ranked No. 1 in this respect, with a length of 394km; Paris came next with 199km; Tokyo was No. 3 with 155km; Washington DC ranked No. 4 with 126 km. Kyoto and Los Angeles were the most interesting, with merely 11km and 28km respectively, nothing comparable with the top 4 cities.

　　第三，在这六个城市每年地铁运送乘客的数量上我们看到一些令人难以预料的数据。东京成为领头羊，有19亿2千7百万之多;巴黎名列第二，有11亿9千1百万;伦敦位居第三，为7亿7千5百万;华盛顿第四，1亿4千4百万;洛杉叽和京都分别是5千万和4千5百万。因此，与其它城市相比可见差距之大。

　　Third, we see some really unexpected figures about the number of passengers transported by the subway system in these six cities. Tokyo took the lead with 1.927 billion; Paris came next with 1.191 billion; London was No. 3 with 775 million; Washington DC was No. 4 with 144 million. Los Angeles and Kyoto had 50 million and 45 million respectively. Therefore, we can see the big difference as compared with other cities.

　　总之，6个城市在地铁的建设历史、地铁长度和年运送旅客能力方面皆呈现出了很大的不同。

　　Overall, the six cities revealed great differences in the history of subway construction, the length of subway lines and the yearly passenger transportation capability.
