.阅读理解
Looking at China's history over the past 60 years，it is apparent that，despite much suffering，the country has achieved huge political，economic and social success，especially during the past three decades.
The press center for the celebration of the 60th founding anniversary of new China was officially opened on the morning of September 22. Zha Shouchen，deputy director of the press center introduced that，during the National Day，there would be 3,200 domestic reporters，and more than 1,300 foreign journalists to come to Beijing to make the covering work.
The press center provided many services for domestic and foreign reporters，such as issuing the press cards to reporters，accepting the interview application，organizing press conferences and activities of group interviews，providing the means of communication and information services for reporters.And the following was the scene.
A grand parade in Beijing on Oct.1，led by the People's Liberation Army and the People's Armed Police Force，showed some of China's latest achievements in defense modernization.About 8,000 military officers，along with tanks and other vehicles，formed a straight line stretching 3 kms.
The military parade was followed by a civilian parade featuring six massive performing groups and 36 formations of about 100,000 people.In addition,60 floats(彩车)represented everything from the country's geographic areas to the previous year's Beijing Olympics.
Everyday life in China is a parade on a grand scale，with citizens now being able to enjoy things their ancestors did not dare to contemplate 100 years ago，things their grandparents took for luxury 60 years ago，and things their parents did not even know how to attempt 30 years ago.
【语篇解读】 本文简要介绍了中华人民共和国60周年国庆的庆祝活动以及60年来中国的巨变。
