Lesson 71; 大本钟简介 英国伦敦著名古钟或称大本钟（Big Ben），是伦敦的传统坐标。 大本钟从1859年就为伦敦城报时，根据格林尼治时间每隔一小时敲响一次，至今将近一个半世纪，尽管这期间大本钟曾两度裂开而重铸。现在大本钟的钟声仍然清晰、动听。自从1859年投入使用后，英国政府每隔五年就要对大本钟实施维护，包括清洗钟体、替换大本钟的报时轮系和运转轮系等。 名称由来 大本钟得名于它在1859年修建时的建造者本杰明爵士（Benjamin Hall），故名“大本”。; 【New words】 1 parliament [pa:l?m?nt] n.议会 2 erect [irekt] v.建起 3 accurate [?kjur?t] adj.准确的 4 official [?fi??l] n.官员 5 Greenwich [grenit?] n.格林尼治 6 observatory [?bz?:v?t?ri] n.天文台 7 check [t?ek] v.检查 8 microphone [maikr?f?un] n.扩音器 9 tower [tau?] n.塔; 1 parliament n.议会，国会 （美）congress member of parliament 国会议员 congressman 国会男议员（美） congresswoman 国会女议员（美） the Houses of Parliament 国会大厦 the British Parliament 英国国会;2 erect 1）v.建起，建造 〖同义：set up， put up， build〗 eg.They are planning to erect a monument. 2) v.竖立，使直立 erect a flagpole 竖立旗杆 erect a tent 搭起帐篷 erection n.建立 eg.

On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time. A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down! ;;【短语总结】 1. 国会大厦 2. 烧毁 3. 得名于 4. 负责 5. 不但…而且 6. 非常准确 7. 与……连接 8. 出故障 9. 没能做…… 10. 从事 11. 一桶油漆 12. 放慢; 【Reading comprehension】 （ ）1.
