阅读材料,完成下列问题。

    清代诗人尚镕写到:“天下好山水,必有楼台收。山水与楼台,又须文字留。”黄河流经千里,山西在黄河边建起鹳雀楼,王之涣为此写下了“白日依山尽,黄河入海流;欲穷千里目,更上一层楼”的千古名句。湖南岳阳楼,范仲淹写下“先天下之忧而忧,后天下之乐而乐”;江西滕王阁,王勃写下“落霞与孤骛齐飞,秋水共长天一色”;湖北黄鹤楼,李白写下“故人西辞黄鹤楼,烟花三月下扬州;孤帆远影碧空尽,唯见长江天际流”。当下,许多城市有名山名水,但只注重修庙建寺,而不注重建楼题词。这实际上是一种短视行为,只看眼前利益,不看长远发展。缺乏文化支撑,必定没有生命力。

    我国历史名楼多建于水陆交通枢纽,多为木质结构,在经历了风霜雨雪的侵蚀或战乱的破坏后,留存至今的多只剩下遗迹(址)。鹳雀楼历唐经宋,元初(公元1272年)毁于战火。数百年来,无数观光游人只能望河兴叹,空留下无尽的遗憾。1997年12月,该楼的复建工程开始,新建的鹳雀楼为仿唐形制,四檐三层,楼内还设有两部楼梯间和两部载人电梯上下相通。2002年9月26日,新鹳雀楼落成并开始接待游人。滕王阁,1300多年来历经兴废28次。现楼是1983年10月1日第29次重修.1989年落成的滕王阁。

    有人认为,这些装了电梯的“名楼”是一种假古董,没必要重建,关于这些“名楼”重建的质疑也一直存在。

    Jeanne Calment, a French woman, became a record breaker on 17 October of 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.

    Jeanne Calment lives in a small old people's home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old in good health than someone of 120. She still has a lively sense of humor. When asked on her 120th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her.

    So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercise every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86.

    A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying: Sorry, I'm still alive!
