Transport bosses say a third of Londoners will have to work from home during 2012 Olympic games to avoid chronic(持续的) overcrowding on the capital's tubes and buses. Commuters(乘车上下班的人) have been told they can expect waits of over half an hour or more for tubes at some of the busiest stations during the games. And Transport for London(TfL) claims some of the busiest areas such as Canary Wharf will only be able to cope if 60 percent of workers change their travel plans. And the Olympics are set to cause chaos(混乱) on the roads too with the creation of special‘games lanes’ likely to bring many main routes to gridlock. 真正的价值并不在人生的舞台上,而在我们扮演的角色中。 2 The controversial lanes will be reserved purely for the use of competitors and VIPs.Even buses and taxis will be barred(禁止) from using them.①Around 5.3 million people are expected to turn up for the 16 days of the London Olympics．August 3 is expected to be the busiest day with around 800，000 people using public transport. Organizers fear a repetition of the 1996 Atlanta Olympics which became known as the ‘Glitch(差错，缺点) Games’ after transport chaos caused many competitors to miss their events. ②London transport commissioner Peter Hendy said he hopes London will copy the Sydney Olympics of 2000，when 27 percent of workers took leave from their jobs. He told the Observer: “I am not going to be responsible for a transport mess like Atlanta.” ③Earlier this month the Mail reported how tube and train drivers will pocket up to￡1，800 in return for promising not to go on strike during next summer's event. ★★1．佳句仿写 ①直到会议开始半个小时后他才露面。(turn up 意为“出现，露面”) ________________________________________________ ②我们将会把郊游推迟到下个星期，那时我们就不会那么忙了。(when 引导非限制性定语从句) _______________________________________________ ③作为对他的帮助的回报，我邀请他到我家吃午饭。(in return for 意为“作为对……的回报”) _______________________________________________ 2．翻译佳句，放眼高考 ①Commuters(乘车上下班的人) have been told they can expect waits of over half an hour or more for tubes at some of the busiest stations during the games. ___________________________________________________________________________________________ ②Organizers fear a repetition of the 1996 Atlanta Olympics which became known as the ‘Glitch(差错，缺点) Games’ after transport chaos caused many competitors to miss their events. ___________________________________________________________________________________________ Period 1 Introduction, Reading and Vocabulary 【学习目标】通过阅读文章，了解北京的交通方式及交通状况 【重难点】通过阅读了解事实信息 【学法指导】通过阅读文章推断作者的语气态度;文章出处 【课前自主预习】P1-3（个人活动+小组内分享） I 单词识记 ★ 1．________n．电线 2．________adj.郊区的；市郊的 3．________vt.展示；陈列 4．________n．执照；许可证 5．________n．收据 6．________n．目的地；终点 7．________vt.探索 8．________n．路线 9．provide vt.________ 10．impressive adj.________ 11．convenient adj.________ 12．pedal vt.& vi.________ 3 13．fare n．________ 14．tricycle n．________ 15．airconditioned adj.________ II. 短语天地 1．________马上，一会儿 2．________与……相连 3．________到处旅行；四处走动 4．be/get stuck in________ 5．under construction________ III. 句型搜索(组内成员自划好句+分享)★ 1．Simply raise your hand，and a taxi appears in no time. 2．There are 20，000 buses and trolleybuses in Beijing，but they can get very crowded. 3．However，there is also a night bus service，provided by buses with a number in the 200s. 【课内活动与交流】 Introduction：Vocabulary and speaking 1.
