大本钟简介 　　英国伦敦著名古钟或称大本钟(Big Ben)，是伦敦的传统地标。 　　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”。 observatory n. 天文台 observe vt. to see or notice sb/sth 看到,注意到，观察到 The police observed a man enter the bank. 警察注意到一个男人走进了银行 to make a remark 说话；评论 He observed that it was a lovely day. check n/v. 检查 n.支票 check in 登记 He has just checked in at the hotel. 他刚刚在旅馆办好住宿手续。 check out 检查出来 tower n. 塔 water tower 水塔 tower bridge 塔桥 Which radio station can it be heard on ?
