为什么说道家文化是中国传统文化的支柱之一？

Tom, Mary, Jason, Ann 和Juliet想根据各自的兴趣爱好挑选自己喜欢阅读的文章。阅读下面某杂志的文章摘要（A----F），选出适合他们阅读的文章。选项中有一项是多余选项。

A. The Forbidden City, situated in the heart of Beijing, is the largest and the most complete imperial palace and ancient building complex in China. It was home to 24 emperors of the Ming (1368—1644) and Qing (1616—1911) dynasties. The construction of the palaces in the Forbidden City began in 1406. The project spread over 15 years and was not completed until 1470. Most of the buildings in the Forbidden City were rebuilt many times, although they maintained the original style.

B. Mount Tai, the leader of the “Five Sacred Mountains”, is located in the center of Shandong Province, spanning the ranges of Tai’an and Jinan. It covers an area of 550 square kilometers, and its main peak is about 1,532.7 meters high. Mount Tai is a natural museum with many cultural relics and artwork like Heavenly Queen Pool, Red Gate Palace and Mid-Heaven Gate. Besides historic relics, Mount Tai has unique natural scenery.

C. Each year, forecasts of when the blossoms will open are headline news. The information is used by cities to plan cherry blossom festival, travel agencies to schedule tours, and ordinary people to choose dates for parties involving lots of eating and drinking under the trees.

D. Hong Kong is perhaps the best shopping place in the world with reasonable prices, various products and best service. In Hong Kong, shopping is not only a “social activity” but also an important part of recreation and a way of life. Visitors can enjoy the shopping environment and experience the fashion trend.

E. The Leaning Tower of Pisa leans because of the unstable soil on which it was built. The construction started in 1173. The building began to lean as soon as the first three floors were completed. Nevertheless, building continued, and the seven-story structure was finished between 1360 and 1370. It leans a bit more each year, and it was closed for repairs in 1990. Engineers worked to stabilize the foundation and straighten it slightly to prevent damage.

F. Centuries ago, the African elephant inhabited most of the African continent. Today, elephants are found only in the south of the Sahara. As a result of the habitat loss, along with poaching（偷猎）, the number of elephants has greatly declined. The decline has caused serious concern about the long-term survival of the species.
