The Daming Temple

Initially(最初) built during the Daming Period of Liu Song Dynasty in the Southern Dynasty, the Daming Temple lies on the hillside of the Shugang Ridge(山脊) in the northwest of Yangzhou. In the Sui Dynasty, the wonderful Qiling Tower was built at the site. In the Tang Dynasty, the abbot(住持) of the Daming Temple Jian Zhen sailed across to Japan to spread Buddhism. The Pingshan Hall was built here in the Song Dynasty The Daming Temple enjoyed its highest fame in the Qing dynasty

The Daming Temple Scenic Spot mainly consists of three parts, the temple complex, the Memorial Hall Of Master Jian Zhen and the Pingshan Hall.

After going through the Gate Hall. You will find two ginkgo trees growing to the north of the hall. Further north stands the main hall of the temple, called the Mahavira Hall(大雄宝殿),which is a one-story building with a triple-eave roof(三重檐屋顶). To the east of the Daming Temple stands the high Qiling Tower. In the Tang Dynasty many a poet like Li Bai, Gao Shi, Bai Juyi and Liu Yuxi visited and climbed the tower and wrote verses. The present Qiling Tower, a nine-story structure reaching 70 metres in height, was rebuilt in 1995 in the style of the Tang Dynasty.

The main building of the Memorial Hall Of Master Jian Zhen is located to the northeast of the Mahavira Hall. Jian Zhen, a famous master of Buddhism in the Tang Dynasty, was a Yangzhou native. He resided in the Daming Temple as the abbor for many years before he left for Japan. Jian Zhen’s sailing to Japan had great influences on Japan.

To the west of the Mahavira Hall is the Pingshan Hall which was built by Ou Yangxiu. After the failure of the reform(改革), he was demoted(贬职)to Yangzhou to take office as the mayor. Years later, Su Dongpo, Ou Yangxiu’s student, came to Yangzhou. In order to memorize his teacher, he built the Guilin Hall behind the Pingshan Hall. Besides, Emperors Kangxi and Qianlong admired Ou Yangxiu for his personality, statesmanship(治国之才) and essays so much that they came here each time they went on their southern inspection tours.

【题目】I think the most terrible thing in life for my little brother is getting up in the morning. He is almost sick when my mother calls, "Herbert! It's seven o'clock! Get up!" Herbert answers, "I'm coming!" and goes right back to sleep. I'm not at all like my brother. I usually wake up before my mother calls me. I jump out of bed and go into the bathroom to take a shower. I get dressed, brush my teeth, comb my hair, and get ready to go downstairs for breakfast as soon as my mother calls. But not Herbert. He just sleeps. A military band (军乐队) in our bedroom could not wake him up. I call him and say, "Get up! Mum will be up here to pull you out of bed if you don't get up immediately!"?? But he just sleeps. After calling a few more times my mother has to come upstairs and pull Herbert out of bed. It's that way every day with my little brother. Perhaps some day he'll learn to get up on time, but I really don't think so.
