Questions 9-18

·Read the following passages and answer questions 9-18.
1. The Palace Museum, known as the Forbidden City, was the imperial palace of the Ming and Qing dynasties. In the early 5th century, the capital of the Ming dynasty was moved from Nanjing to Beijing. Twenty four emperors of the Ming and Qing dynasties ruled in the Forbidden City. The last dynasty fell in 1911, but Emperor Puyi still lived in the inner court. It was not until 1925 that the complex was converted into a museum. Since then the palace has been open to the public.
2. The large-scale construction involved 100,000 artisans and 1,000,000 civilians. The material needed for building the palace came from all over the country. In the Qing dynasty, the timber came mostly from Sicbuan, Guangdong, Guangxi, Yunnan provinces. The gold brick was made in Suzhou. The glazed tiles were made in Sanjiadian, Beijing.
3. The Palace Museum is located in the center of Beijing, covering an area of 72 hectares. The floor square is 163,000 square meters. It is 961m long from south to north, and 753m wide from east to west.
4. According to the calculations made in 1973, there are more than 90 courtyards, 980 buildings and 8704 room units inside the Forbidden City. During the Ming and Qing dynasties, the number of building varied, and so there was no fixed number of rooms.
5. The astronomers in ancient China divided the main fixed stars into three Yunan. Ziweiyuan is the residence of the heavenly emperor, it is in the middle and also called Zi palace. The feudal emperors call themselves the sons of heaven and called the palace they lived in the symbol of Zi palace in heaven. The palace where the emperor resided was completely forbidden for the common people. So that is why it is called the Forbidden City. In the 1992 comments on Beijing attractions in World Travel Wonders, experts commented that the Forbidden City was the largest, best preserved palace complex remaining in the world today. The Forbidden City was placed on the World Cultural Heritage List by UNESCO in 1987.
