英国前首相丘吉尔说：“我们塑造了建筑，而建筑反过来也影响着我们”。下列是一组具有政治意义的建筑图片。请阅读并回答问题。

材料一 明清故宫建于北京城中央，以南北为中轴线，座北朝南，充分体现了皇权至高无上的封建统治思想。在宫城外又有北京城，城城包围，显示了森严的等级制度。 

材料二 依泰晤士河而建的英国议会大厦是英国的政治中心。它不仅外表雄伟壮观、内部装饰华丽，而且其建筑结构和内部设计也能充分体现世界上最古老的君主立宪政体。

These days, many passers-by always spot a beggar on the Jiaochangkou Street in Yuzhong District of Chongqing in southwest China.

The beggar’s name is Xia Haibo, and he was born in Meihe Village, Tianmen City of Hubei Province. Being 25 years old, he is quite a special beggar in some ways — he doesn’t beg on his knees, as other beggars do when begging. Rather, he often stands in the crowded street, either reading a book or thinking about something carefully. He also started a blog on the Internet which has been clicked more than 500,000 times. He likes reading — he has read many classical Chinese poems. He has kept writing and recently, he has planned to publish his writings.

In 1998, Xia entered Tianmen Middle School as the best student in his town. However, a year before he took the college entrance examination, he came down with a high fever and was later diagnosed (诊断) as having rheumatoid arthritis (类风湿性关节炎). In order to treat his disease, his father borrowed 60,000 yuan from relatives and friends. However, with this money, he didn’t recover from the disease. He did not want to become a burden (负担) to his family any more. So in July, 2006, he left his hometown and went to Wuhan to make a living by begging.

Begging has become a job to Xia now. However, he doesn’t plan to go on living like this. “By July 24, 2008, when I have been begging for two years, I will stop my begging life. I promise,” he said.

It is his plan that by using the money he “earns”, he will rent a small shop in his hometown and keep on writing in his spare time.

Right now, he is trying to finish a book of his own. The book, called Love Is With Me, tells about the people who helped him during his begging life.
