19．You may ride on your bicycle in a rush to get to school every morning．You may fight to get a bit of space on a bus or on the subway．You may also watch taxis crawl their way through traffic jams．No matter where you are，all big cities around the worl have traffic jams these days．But although they all have their problems，many cities also have a type of transport that has become a cultural icon （文化標識）．In London to avoid the traffic above ground，people use the"underground"，also called the"Tube"．The city has the oldest and most complicated underground railway system in the world and is the pride of many Londoners．With 12lines and 275stations across the city，the Tube，is normally the quickest and easiest way of getting around London．In London，you are never far from a Tube station．New York is famous for its Yellow cabs．They serve as a quick and easy way of getting across Manhattan，where the subway doesn't take you everywhere．Stopping a cab is easy； just stick out your arm like you do in any city．But，with over 12，000yellow cabs in the Big Apple，they also cause traffic jams．Since 1873when the first cable car started public service，the slow and noisy vehicle has been a symbol of San Francisco．Although once damaged by a serious earthquake and challenged by cars，it is never caught in traffic jams and provides better views than the subway．But there are no such symbols in Los Angeles．If you visit you'd better rent a car．The city's public transportation is terrible．It can take hours to get across town by bus．The subway covers just a small part of the city centre．The light rail line only runs between the Long Beach hotel area and the city centre．That's why Angelenos love their private cars more than any other people in the world．

分析 本文主要講述了世界上的幾個大城市里交通堵塞情況，以及某些解決辦法．
解答 21．C 細節理解題．根據短文第三段內容In London to avoid the traffic above ground，people use the"underground"，also called the"Tube"．The city has the oldest and most complicated underground railway system in the world and is the pride of many Londoners．With 12lines and 275stations across the city，the Tube，is normally the quickest and easiest way of getting around London可知，在倫敦，為了避開地面擁擠的交通，人們都會選擇乘坐地鐵．它包括12條線路和275個車站，是暢游倫敦最快捷簡便的途徑．故選C．
22．D 推理判斷題．根據第四段內容New York is famous for its Yellow cabs．They serve as a quick and easy way of getting across Manhattan，where the subway doesn't take you everywhere．Stopping a cab is easy； just stick out your arm like you do in any city．可知，紐約最著名的交通工具是黃色出租車．坐這種出租車出行快速、簡便，只需你一招手便可以打到出租車．據此可以推測"黃色出租車"是紐約的"文化標識"．故答案選D．
23． B 細節理解題．根據短文最后一段Since 1873when the first cable car started public service，the slow and noisy vehicle has been a symbol of San Francisco．Although once damaged by a serious earthquake and challenged by cars，it is never caught in traffic jams and provides better views than the subway．But there are no such symbols in Los Angeles．If you visit you'd better rent a car．The city's public transportation is terrible．It can take hours to get across town by bus．The subway covers just a small part of the city centre．The light rail line only runs between the Long Beach hotel area and the city centre．That's why Angelenos love their private cars more than any other people in the world．可知，這個城市公共交通狀況糟透了．坐公交車穿越整個城市需數個小時．地鐵只覆蓋了市中心的一小部分．因此，洛杉磯市民比世界上其他人更喜歡私家車．只有B沒有提到，故答案選B．
24． A 主旨大意題．根據短文第一、第二段可知，本文的中心話題是世界上所有的大城市現在都有交通問題．為解決這一難題，作者列舉了倫敦、紐約、舊金山和洛杉磯等一些大城市的做法．由此可得出答案選A．
